For two PEMAc molecular weights and two pulp types, the power-law slopes were 0.6; however, the pre-exponential terms depended upon the specific polymer and pulp type combination. We propose that the relationships between the wet tensile index and βΓ, from polymer-treated, laboratory pulp handsheets, can be used to predict if proposed curing conditions for larger-scale processes will produce a repulpable product.Condensed deposition favors biochemical analysis, bioassays, and clinical diagnosis, but the existing strategies may suffer from low resolution, inaccurate control, cross-contamination, or miscellaneous apparatus. Herein, we propose a noncontact light strategy to enable the condensed deposition for droplet evaporative crystallization, in which the photothermal effect of a focused infrared laser is employed to induce intense evaporation. Due to the localized heating effect, not only can the droplet evaporative crystallization on the hydrophobic substrate be promoted, but also the resultant intensified Marangoni flow enables the movement of the early-formed crystals, preventing the pinning of the triple-phase contact line. Synergy of the Marangoni flow and nonuniform evaporation makes the solutes tend to accumulate near the focused light beam region, which facilitates the condensed deposition. More importantly, this light strategy not only enables condensed deposition on the hydrophobic surface with low hysteresis, but also works successfully on the hydrophilic substrate with high hysteresis via adjusting input laser power. It is demonstrated that the light strategy proposed in the present study has great potential for relevant applications.Nanocomposites combine multiple favorable properties to achieve intriguing functionalities, but the formation of nanocomposites with only one constituent with the inclusion of multiple superior properties is still not known. Herein, novel self-compounded nanocomposite membranes from one single polymer-cellulose cinnamate (CCi)-with multiple outstanding properties are reported. The self-compounded membranes contain two distinct morphologies as CCi nanoparticles (CCi-NPs) and a CCi polymer matrix, while CCi-NPs are either firmly embedded in the CCi matrix or fused with adjacent CCi-NPs. The unique self-compounded nanostructure endows the membranes with a tensile strength of 94 MPa and Young's modulus of 3.1 GPa. The water vapor permeability, oxygen permeability, and oil permeability reach as low as (0.94 ± 0.03) × 10-11 g m-1 s-1 Pa-1, (8.48 ± 2.39) ×10-13 cm3·cm/cm2·s·cmHg, and 0.008 ± 0.003 g mm m-2 day-1, respectively. Moreover, self-compounded CCi nanocomposite membranes also demonstrate UV-shielding and photothermal conversion properties. UVB and UVC light are entirely blocked, while UVA light is partly blocked. The temperature increases from room temperature to 120 °C within 1 min under UV irradiation. https://www.selleckchem.com/products/lipofermata.html In addition, CCi membranes also show remarkable thermal and humidity resistance. Based on these outstanding properties, CCi membranes are applied as food packaging materials. This work offers a new avenue to construct nanocomposites with multiple superior properties from one constituent, which is promising for diverse applications.Arsenic species transformation in paddy soils has important implications for arsenic accumulation in rice grains and its safety to the consumers. Methylated thioarsenates including highly toxic dimethylated monothioarsenate (DMMTA) have been detected in paddy soils, but their production and dynamics remain poorly understood. In the present study, we first optimized a HPLC-ICP-MS method to quantify methylated thioarsenate species. Using this method together with 10 mM diethylenetriamine pentaacetate (DTPA) to preserve As speciation, we investigated methylated thioarsenate species in porewaters of seven As-contaminated soils incubated under flooded conditions and of two paddy fields. DMMTA was the main methylated thioarsenate species in the porewaters in both incubated soils and paddy fields, with concentrations ranging from 0.2 to 36.2 μg/L and representing ca. 58% of its precursor dimethylarsenate (DMA). The temporal production and dynamics of DMMTA were linked with the DMA concentrations. When soils were drained, DMMTA was converted to DMA. In the two paddy fields, DMMTA concentrations in rice grains were 0.4-10.1 μg/kg. Addition of sulfur fertilizer and rice straw incorporation increased grain DMMTA by 9-28%. These results suggest that DMMTA is an important As species in paddy soils and can accumulate in rice grains, presenting a risk to food safety and human health.Porphyria is a group of genetic photodermatoses that cause too much porphyrin to accumulate in the blood, skin, and liver, resulting in skin photosensitivity and damage, liver disease, or potential liver failure. Conventional detection methods include high-performance liquid chromatography and fluorescence spectrometry. However, these methods usually require complicated pretreatment and time-consuming processes. Therefore, efficient and fast detection of porphyria is urgently needed. Herein, we develop a molecular afterglow reporter-based sensing scheme for the detection of porphyrins in whole blood. The afterglow reporter can respond to the production of singlet oxygen (1O2) of porphyrins after light excitation, and the detection signals can be amplified through adjusting the amount of singlet oxygen and afterglow reporter molecules. Moreover, without the use of a real-time excitation source, afterglow signals can avoid the scattering and autofluorescence interference in biological samples, thereby reducing background noise. More importantly, we prove the applicability of the afterglow reporter in the quantitative detection of porphyrins in whole blood and demonstrate its great clinical potential. Exercise can have a positive effect on body functioning and immunity. This study systematically evaluated the effect of exercise intervention on patients diagnosed with primary insomnia. Based on the meta-analysis, we developed exercise recommendations to help improving sleep quality in these patients. Using a combination of manual and electronic retrieval strategies, we examined the CNKI, VIP, Wanfang, Web of Science, SpringerLink, EBSCO, PubMed, Cochrane Library, and Embase databases; and identified randomized controlled trials that addressed the effects of exercise intervention on primary insomnia and were published before October 2019. Risk of bias was assessed based on the Cochrane Handbook 5.1.0, and meta-analysis was conducted using STATA 13.0 (StataCorp LLC; College Station, TX, USA). Data were included for 1269 patients who received exercise interventions and 1203 patients who received drug therapy or no intervention (controls) in 23 trials of high quality. Meta-analysis showed that exercise intervention had a significant effect on the treatment of primary insomnia (SMD -1.

Long-term brown coal mining contributes to risk element contents in soils surrounding coal basins. However, there is a lack of bioaccessibility characterization of the risk elements in the soils at the impacted locations for estimation of the potential health risk, in relation to the effects of soil particle size and element origin. In this study, soils from different geological areas (geogenic vs. anthropogenic) were sampled around the Most brown coal basin, Czech Republic. These soils were passed through sieves to obtain seven aggregate size fractions. For an estimation of the oral bioaccessibility of As and Pb in the size fractions, the physiologically based extraction test was applied, whereas the potential pulmonary bioaccessibility of the elements was estimated by using both Gamble's and Hatch's tests. The results showed that the geochemical pattern of the investigated elements clearly separates the soil samples collected from the mountain region (mineralization from geogenic processes) from those of the basin region (extensive coal mining). For As, the results indicated that it poses higher risks in the anthropogenically affected basin region due to its higher gastro-intestinal and pulmonary bioaccessibility in soil samples in this area. A higher bioaccessibility of As in the soils was recorded in the finer grain size fractions, which are usually air-borne and can be easily ingested and/or inhaled, leading to potential health risks to humans and livestock. The opposite pattern, with a higher content on coarse particles, was recorded for Pb, indicating a potential risk of livestock in the non-forest mountainous areas.This study aims to formulate and fabricate the optimum condition of modified kenaf core (MKC) for the removal of targeted endocrine-disrupting compounds in a batch adsorption system. Kenaf core was chemically modified using phosphoric acid as an activating agent, which involved the pyrolysis step. Results indicated a significant difference (p  T3KC for E2 and EE2 adsorption, respectively, through hydrogen bonding and the π-π interaction mechanism. Thus, the findings revealed T2KC at a moderate level of acid concentration (0.5 M H3PO4) to be a potential biochar, with an environmentally safe and sound profile for opposing emerging pollutant issues as well as for the attainment of sustainable development goals.Oleogel consists of hydrophobic solvent and an oleogelator. In this study, attempts were made to study the influence of Celecoxib solubility, concentration and dispersability on its release, absorption, and biological performance. Oleogels were prepared to study the formulation variables on its stability and release. Castor oil was selected as the oil and the oleogelator concentration was 4.5% w/w. F3 revealed the highest release and stability compared to other formulae. The percent permeated across the rat intestine showed a 7.5-fold increase over free Celecoxib, and its lifetime was found to be greater than 18 months. The efficacy of free Celecoxib and oleogel formulae to treat rats with ulcerative colitis was done via the induction of ulcerative colitis (UC) through administration of 5% dextran sodium sulphate (DSS). https://www.selleckchem.com/products/gsk2643943a.html Celecoxib besides its formulae significantly reduced the release of Leucine rich 2 glycoprotein (LRG), Myeloperoxidase (MPO), Tumor necrosis factor-α (TNF-α), proinflammatory cytokine expression, High mobility group box 1 (HMGB1), Nuclear factor kappa B (NF-ΚB), Trefoil Factor 3 (TFF3), Metalloproteinase-3 (MMP3), and miRNA31. Moreover, F3 significantly increased the colonic cAMP in DSS treated rats and reduced the intestinal inflammation beside healing of mucosa and restitution of the epithelium of the gastrointestinal tract. Polypharmacy (PP) is common in end-stage chronic renal disease patients largely due to the presence of multiple comorbid conditions. Although PP is potentially harmful, its relationship with mortality and morbidity in hemodialysis patients currently remains unclear. Study design cohort study. participants one hundred and fifty-two initial hemodialysis patients (male, 88 patients; mean age, 70.3years) were enrolled between February 2015 and March 2018 at Nobeoka Prefectural Hospital and Chiyoda Hospital. patients were divided into 2 groups according to PP (6 or more drug prescriptions or less) during admission and discharge for the initiation of hemodialysis. all-cause mortality and hospitalization during the mean 2.8-year follow-up. hazard ratios (HRs) were estimated using Cox's model for the relationships between PP and clinical outcomes and adjusted for potential confounders. The group with 5 or less drug prescriptions was set as a reference. The number of prescribed drugs per patient averaged 7.4 at admission and 7.0 at discharge for initial hemodialysis. One hundred (65.8%) and 94 patients (61.8%) had PP at admission and discharge, respectively. During the follow-up, 20 patients died and 71 were hospitalized. PP at admission did not correlate with outcomes, whereas that at discharge correlated with all-cause hospitalization. PP at discharge may be associated with clinical outcomes. However, it remains unclear whether PP is the direct cause of outcomes or is simply a marker for an increased risk of outcomes. PP at discharge may be associated with clinical outcomes. However, it remains unclear whether PP is the direct cause of outcomes or is simply a marker for an increased risk of outcomes. The majority of active tuberculosis (TB) cases develop from latent tuberculosis infection (LTBI). Since the risk of TB in hemodialysis (HD) patients is particularly high, interferon-gamma release assay (IGRA) for LTBI screening in HD patients is considered important. However, the prevalence and characteristics of LTBI in Japanese HD patients remain obscure. We performed an observational cross-sectional study of LTBI using IGRA QFT-3G tests in 118 HD outpatients enrolled at 3 hospitals of varying location and function. Of the 118 patients, 96 were QFT negative, 7 were QFT indeterminate, 14 were QFT positive, and 1 was QFT judgment impossible. No patient had active TB. Confirmed (QFT positive) and possible (QFT positive + indeterminate) LTBI patients totaled 14 (11.9%) and 21 (17.8%), respectively. The LTBI possible group was significantly older and had a significantly higher rate of nephrosclerosis versus the QFT-negative group. The indeterminate group had a significantly longer HD period. The QFT results were not remarkably affected by other clinical data, including hospital characteristics.

s than primary LND, and it may be omitted in LAMN+G1 or in any Tis and T1 PATs. Overactive bladder (OAB) is a prevalent condition commonly treated with anticholinergic medications. The extent to which anticholinergic burden is associated with costs and healthcare resource use (HCRU) in the long-stay nursing home (LSNH) setting is currently unknown. This research evaluated the impact of anticholinergic burden on HCRU and related costs among LSNH residents with OAB. This was a cohort study based on 2013-2015Minimum Data Set-linked Medicare claims data involving LSNH residents aged ≥ 65 years with OAB and having Parts A, B and D coverage 6 months pre- and ≥ 12 months post-nursing home admission date (index date). Cumulative anticholinergic burden was determined using the Anticholinergic Cognitive Burden scale and defined daily dose. Direct medical costs related to HCRU were examined. HCRU included inpatient, outpatient, emergency room (ER), and physician office visits. Costs and HCRU associated with levels of anticholinergic burden were evaluated using generalized linear models. A total of 123,308 LSNH residents with OAB were included in this study. Most residents (87.2%) had some level (12.8%, none; 18.0%, low; 41.9%, moderate; and 27.3%, high) of cumulative anticholinergic burden. Results indicate that all types of resource utilization were higher among those with any level of anticholinergic burden than those with no burden. The outpatient, ER, and physician costs tended to be higher with increasing anticholinergic burden. Costs and HCRU patterns reflected increasing trends with anticholinergic burden. Targeted efforts towards reducing anticholinergic burden among LSNH residents with OAB may result in decreases in costs and HCRU. Costs and HCRU patterns reflected increasing trends with anticholinergic burden. Targeted efforts towards reducing anticholinergic burden among LSNH residents with OAB may result in decreases in costs and HCRU.Traditional herbal medicines, which have been used in the matured traditional medical systems as well as those have been used in ethnic medical systems, are invaluable resources of drug seeds. Ethnobotanical and ethnopharmacological survey may provide useful information of these herbal medicines, which are valuable for searching new bioactive molecules. From this viewpoint, we have been performing the ethnobotanical and ethnopharmacological field studies in Yunnan Province and Guangxi Zhuang Autonomous Region, China, and Mongolia. Phytochemical studies on traditional herbal medicines were performed based on the information obtained by our ethnobotanical survey. Herbal medicines used in Uzbekistan and Bangladesh were also investigated on the basis of the ethnopharmacological information obtained from collaborative researchers in the respective regions. Some studies were carried out for searching active substance(s) based on bioassay-guided fractionation and isolation. Over 150 new molecules were isolated in these studies, and their various biological activities were also demonstrated. This review summarizes the results of phytochemical studies of those traditional herbal medicines as well as biological activities of the isolated molecules.A 39-year-old previously healthy woman was referred to our emergency department by a primary care doctor on suspected to be acute enteritis, complaining of fever, anorexia, lower abdominal pain, and frequent diarrhea. The day after admission, although frequent diarrhea stopped, the abdominal distension worsened. An abdominal radiograph revealed several dilated loops of the small bowel, suggested that small bowel obstruction (SBO) had developed. White blood cell count and c-reactive protein were markedly increased, and abdominal contrast-enhanced computed tomography scan showed localized severely edematous bowel mucosa, increased adipose tissue concentration in the pelvis, and a beaded low absorption area in the uterus. https://www.selleckchem.com/products/ginkgolic-acid-s9432.html Gynecological examination revealed the presence of a pus-filled plastic intrauterine device (IUD) in the uterus. The patient confided that she had sex with her husband 2 days before the onset of symptoms. A diagnosis of SBO due to pelvic peritonitis caused by IUD infection during sexual activity was made. The SBO was cleared in 12 days with fasting, peripheral parenteral nutrition, antibiotic treatment, and insertion of an ileus tube. This case reminds us that it needs to consider disorders associated with the uterine appendages, in women of reproductive age with lower abdominal pain.Pancreatic cancer is the fourth leading cause of cancer-related death in Japan. Pancreatic cancer is categorized as resectable, borderline resectable, or unresectable based on the degree of adjacent vascular invasion and the presence of distant metastases. Neoadjuvant chemotherapy with gemcitabine and S-1 (NAC-GS) has recently become a standard option for resectable pancreatic cancer in Japanese patients. According to previous reports, GS is considered to be relatively safe and feasible treatment for Japanese patients, including the elderly. However, NAC-GS is occasionally associated with severe adverse events which may ultimately render the patient unfit for surgery. A 60-year-old man with resectable pancreatic cancer suffered from severe necrotic enteritis during NAC-GS, which required surgical resection. Considering the time course and histological findings of the resected bowel, S-1 was believed to be the causative agent. The low urinary dihydrouracil to uracil ratio also suggested possible dihydropyrimidine dehydrogenase deficiency, which may have hindered the metabolism of S-1 and contributed to the development of necrotic enteritis. Life-threatening enteritis occurs in approximately 0.3% of all patients who receive S-1. As initial symptoms are non-specific, patients should be instructed to lower the hurdle for contacting the hospital during NAC-GS. To evaluate the relationship between the position and impaction level of the impacted maxillary third molar teeth and marginal bone loss, caries and resorption findings on the distal surface of the second molar teeth with cone beam computerized tomography (CBCT) scans. All CBCT images of 189 impacted maxillary teeth belonging to 121 patients were examined by an observer. After determining the position and impaction level of the impacted maxillary third molar teeth, presence of caries, resorption and marginal bone loss in the distal of the second molar tooth were evaluated.IBM SPSS Statistics 22.0 (IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY IBM Corp.) was used for statistical analyses and calculations. Data were analysed using the Chi-square test and Fisher's exact test. A statistically significant difference was found in terms of the impaction level of the impacted maxillary third molar tooth and the presence of caries in the distal surface of the second molar tooth, in terms of the impaction level of the impacted third molar tooth and the presence of marginal bone loss in the distal surface of the second molar tooth.

Statistical assessment of continuous data was done with student t-test and nominal data was evaluated using X2-test and logistic regression. Results Forty infants were included with mean gestational age at birth of 29.5 ± 3.4 weeks and mean birth weight of 1.3 ± 0.5 kg. Mean time between lab draws while on same IL dose was 11.6 ± 0.2 h with resulting mean fasting and non-fasting (random) TG levels 82 ± 40 mg/dL (95% CI 68.4, 97.6) and 101 ± 40 mg/dL (95% CI 88.5, 115.8), respectively. Mean difference between TG levels during lipid-free interval and during infusion was -18.6 ± 51.2 mg/dL (95% CI -35.0, -2.3; p = 0.03). Conclusion We concluded there is no difference in the management of IL, when TG level was drawn randomly or as fasting sample. Obtaining TG level during routine lab draws is appropriate. We extrapolated that the administration of IL over 24 h will not interfere with TG level. One of the microRNAs (miRNAs) known to be associated with cancer development is miR-607. https://www.selleckchem.com/products/bms309403.html The aim of this study is to investigate the clinical significance and diagnostic and prognostic value of miR-607 and to explore its potential role in pancreatic ductal adenocarcinoma (PDAC). The expression levels of miR-607 were assessed by quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between miR-607 expression and clinical characteristics was analyzed by the Chi-square test. Overall survival (OS) and progression-free survival (PFS) were evaluated via the Kaplan-Meier method, and the association between miR-607 expression and OS was investigated by the Cox proportional hazard analysis. The diagnostic value was estimated via receiver operating characteristic (ROC) curve analysis. The effect of miR-607 overexpression on cell migration, invasion, and epithelial-mesenchymal transition (EMT) was determined by wound-healing, Transwell invasion, and Western blotting assays. miR-607 levels wer may serve as a potential diagnostic and prognostic biomarker through regulation of tumor metastasis in PDAC patients. Low serum miR-607 level may serve as a potential diagnostic and prognostic biomarker through regulation of tumor metastasis in PDAC patients. Gaps in coordination and transitions of care for liver cirrhosis contribute to high rates of hospital readmissions and inadequate quality of care. Understanding the differences in the mental models held by specialty and primary care physicians may help to identify the root causes of problems in the coordination of cirrhosis care. To compare and identify differences in the mental models of cirrhosis care held by primary and specialty care physicians and nurse practitioners that may be addressed to improve coordination and transitions. Cross-sectional formal elicitation of mental models using Cognitive Task Analysis. Purposive and chain-referral sampling to select family physicians (  = 8), specialists (  = 9), and cirrhosis-dedicated nurse practitioners (  = 2) across Alberta. Family physicians do not maintain rich mental models of cirrhosis care. They see cirrhosis patients relatively infrequently, rebuilding their mental models when required (knowledge on demand). They have reactive and patient-neg a shared mental model of responsibilities for addressing medical care and social determinants of health.Metabolic associated fatty liver disease (MAFLD) is a multifactorial systemic disorder that occurs in the absence of excessive alcohol consumption. The disease is characterized by fatty degeneration and fat accumulation in liver parenchymal cells, the incidence of which is increasing annually, particularly in younger adults. MAFLD is caused by genetic and metabolism related disorders, of which mitochondrial dysfunction is the major contributor. Natural products can relieve MAFLD through restoring mitochondrial function. In this article, we describe the relationship between mitochondria and MAFLD and discuss the beneficial effects of natural products as a future anti-MAFLD strategy. Significance Statement. We herein propose that the development of mitochondrial regulators/nutrients from natural products can remedy mitochondrial dysfunction which represents an attractive strategy for the treatment of MAFLD. Furthermore, the mitochondrial regulation of natural products can provide new insight into the underlying mechanisms of action of natural products used for future MAFLD therapeutics.Coronavirus disease 2019 (COVID-19) exhibit mild to moderate symptoms, whereas 15% of COVID-19 cases progress to pneumonia, some associated cutaneous findings are also reported as maculopapular eruptions, morbilliform rashes, urticaria, chickenpox-like lesions, and livedo reticularis. The inactivated COVID-19 vaccines are authorized for use in some countries including Turkey. Here, we report an unusual case of varicella-zoster virus (VZV) reactivation in a 68-year-old male patient who was vaccinated against COVID-19. The patient presented to family medicine clinic with a stinging sensation and pain radiating from the right side of his chest to his back. Physical examination revealed multiple pinheaded vesicular lesions upon an erythematous base occupying an area on his right mammary region and back corresponding to T3-T5 dermatomes. He reported that he got his second dose of COVID-19 vaccine 5 days ago. As COVID 19 decreases the cell-mediated immunity, it could also increase the risk of herpes zoster (HZ). Although the exact reason remains unsolved, vaccine-induced immunomodulation caused by live attenuated vaccines and attenuated alloreactivity caused by inactivated vaccines may be responsible mechanisms for the reactivation of HZ. Epidemiological studies are needed to clarify the possible connection between vaccination and reactivation of herpesvirus infections.Novel anti-coronavirus disease 2019 mRNA vaccines are rapidly implemented worldwide. Therefore, attention should be given to potentially life-threatening adverse reactions. We report on three young male patients, who developed acute myocarditis 2 days after receiving the second dose of the BNT162b2 vaccine. Primary acute myocarditis was not previously reported in association with vaccines that do not include adjuvants. A high index of suspicion should be maintained in order to diagnose and treat patients who develop auto-inflammatory vaccine-related complications in a timely manner. Further research is required in order to explore the significance of this phenomenon and its underlying molecular mechanism.

OBJECTIVE To identify sleep duration trajectories from early to middle adulthood and their associations with incident type 2 diabetes. RESEARCH DESIGN AND METHODS Using a group-based modeling approach, we identified sleep duration trajectories based on sleep duration in ages 20-25, 26-35, 36-45, and 46+ years, which were retrospectively assessed in 2009 among 60,068 women from the Nurses' Health Study II (median age 54.9 years) who were free of diabetes, cardiovascular disease, and cancer. We investigated the prospective associations between sleep duration trajectories and diabetes risk (2009-2017) using multivariable Cox proportional hazards models. RESULTS We documented 1,797 incident diabetes cases over a median follow-up of 7.8 years (442,437 person-years). Six sleep duration trajectories were identified persistent 5-, 6-, 7-, or 8-h sleep duration and increased or decreased sleep duration. After multivariable adjustment for diabetes risk factors, compared with the persistent 7-h sleep duration group, the hazard ratio was 1.43 (95% CI 1.10, 1.84) for the 5-h group, 1.17 (1.04, 1.33) for the 6-h group, 0.96 (0.84, 1.10) for the 8-h group, 1.33 (1.09, 1.61) for the increased sleep duration group, and 1.32 (1.10, 1.59) for the decreased sleep duration group. Additional adjustment for time-updated comorbidities and BMI attenuated these associations, although a significantly higher risk remained in the decreased sleep duration group (1.24 [1.03, 1.50]). CONCLUSIONS Persistent short sleep duration or changes in sleep duration from early to middle adulthood were associated with higher risk of type 2 diabetes in later life. These associations were weaker after obesity and metabolic comorbidities were accounted for. © 2020 by the American Diabetes Association.OBJECTIVE To determine if temporal glucose profiles differed between 1) women who were randomized to real-time continuous glucose monitoring (RT-CGM) or self-monitored blood glucose (SMBG), 2) women who used insulin pumps or multiple daily insulin injections (MDIs), and 3) women whose infants were born large for gestational age (LGA) or not, by assessing CGM data obtained from the Continuous Glucose Monitoring in Women With Type 1 Diabetes in Pregnancy Trial (CONCEPTT). RESEARCH DESIGN AND METHODS Standard summary metrics and functional data analysis (FDA) were applied to CGM data from the CONCEPTT trial (RT-CGM, n = 100; SMBG, n = 100) taken at baseline and at 24- and 34-weeks gestation. Multivariable regression analysis determined if temporal differences in 24-h glucose profiles occurred between comparators in each of the three groups. RESULTS FDA revealed that women using RT-CGM had significantly lower glucose (0.4-0.8 mmol/L [7-14 mg/dL]) for 7 h/day (0800 h-1200 h and 1600 h-1900 h) compared with those with SMBG. Women using pumps had significantly higher glucose (0.4-0.9 mmol/L [7-16 mg/dL]) for 12 h/day (0300 h to 0600 h, 1300 h to 1800 h, and 2030 h to 0030 h) at 24 weeks with no difference at 34 weeks compared with MDI. Women who had an LGA infant ran a significantly higher glucose by 0.4-0.7 mmol/L (7-13 mg/dL) for 4.5 h/day at baseline; by 0.4-0.9 mmol/L (7-16 mg/dL) for 16 h/day at 24 weeks; and by 0.4-0.7 mmol/L (7-13 mg/dL) for 14 h/day at 34 weeks. CONCLUSIONS FDA of temporal glucose profiles gives important information about differences in glucose control and its timing, which are undetectable by standard summary metrics. Women using RT-CGM were able to achieve better daytime glucose control, reducing fetal exposure to maternal glucose. © 2020 by the American Diabetes Association.BACKGROUND Air pollution is a risk factor for chronic obstructive pulmonary disease (COPD). Fraction of exhaled nitric oxide (FeNO) could be a useful biomarker for health effects of air pollutants. However, there were limited data from older populations with higher prevalence of COPD and other inflammatory conditions. METHODS We obtained data from the German Study on the influence of Air pollution on Lung function, Inflammation and Ageing. Spirometry and FeNO were measured by standard techniques. Air pollutant exposures were estimated following the European Study of Cohorts for Air Pollution Effects protocols, and ozone (O3) measured at the closest ground level monitoring station. Multiple linear regression models were fitted to FeNO with each pollutant separately and adjusted for potential confounders. RESULTS In 236 women (mean age 74.6 years), geometric mean FeNO was 15.2ppb. Almost a third (n=71, 30.1%) of the women had some chronic inflammatory respiratory condition. A higher FeNO concentration was associated with exposures to fine particles (PM2.5), PM2.5absorbance and respirable particles (PM10). There were no significant associations with PMcoarse, NO2, NOx, O3 or length of major roads within a 1 km buffer. Restricting the analysis to participants with a chronic inflammatory respiratory condition, with or without impaired lung function produced similar findings. Adjusting for diabetes did not materially alter the findings. There were no significant interactions between individual pollutants and asthma or current smoking. CONCLUSIONS This study adds to the evidence to reduce ambient PM2.5 concentrations as low as possible to protect the health of the general population. © Author(s) (or their employer(s)) 2020.

However, the long-term future of maintenance programs is dependent on quality evidence. METHODS AND ANALYSIS The ComEx3 randomised controlled trial will investigate the efficacy of extending a weekly supervised maintenance programme for an additional 6 months following an initial 10-week maintenance programme (intervention) by comparing with a control group who receive the same 10-week maintenance programme followed by 6 months of usual care. 120 participants with COPD will be recruited. Primary objective is to determine health-related quality of life over 12 months. Secondary objectives are to determine functional exercise capacity trajectory and to perform an economic evaluation of the intervention to the health system.

Trait anxiety is considered a susceptible factor for stress-related disorders, and is characterized by abnormal brain activity and connectivity in the regions related to emotional processing (e.g., the amygdala). However, only a few studies have examined the static and dynamic changes of functional connectivity in trait anxiety. We compared the resting-state static and dynamic functional connectivity (sFC/dFC) in individuals with high trait anxiety (HTA, n = 257) and low trait anxiety (LTA, n = 264) using bilateral amygdala subregions as the seeds, that is, the centromedial amygdala (CMA), basolateral amygdala (BLA), and superficial amygdala (SFA). The CMA, BLA, and SFA all showed reduced sFC with the executive control network (ECN) and anomalous dFC with the default mode network (DMN) in individuals with HTA. The CMA only showed reduced sFC with the ECN and reduced dFC with the DMN in individuals with HTA. The BLA showed reduced sFC with the salience network (mainly in the anterior and median cingulate), and increased dFC between the BLA and the DMN in individuals with HTA compared to those with LTA. Notably, HTA showed widespread anomalous functional connectivity in the SFA, including the visual network, mainly in the calcarine fissure, limbic system (olfactory cortex), and basal ganglia (putamen). The anomalous sFC and dFC in individuals with HTA may reflect altered mechanisms in prefrontal control, salient stimuli processing, and amygdaloidal responsivity to potential threats, leading to alterations in associative, attentional, interpretative, and regulating processes that sustain a threat-related processing bias in HTA individuals. The anomalous sFC and dFC in individuals with HTA may reflect altered mechanisms in prefrontal control, salient stimuli processing, and amygdaloidal responsivity to potential threats, leading to alterations in associative, attentional, interpretative, and regulating processes that sustain a threat-related processing bias in HTA individuals. While MR enterography allows detection of inflammatory bowel disease (IBD), the findings continue to be of limited use in guiding treatment-medication vs. surgery. To test the feasibility of MR elastography of the gut in healthy volunteers and IBD patients. Prospective pilot. Forty subjects (healthy volunteers n=20, 37 ± 14 years, 10 women; IBD patients n=20 (ulcerative colitis n=9, Crohn's disease n=11), 41 ± 15 years, 11 women). Multifrequency MR elastography using a single-shot spin-echo echo planar imaging sequence at 1.5 T with drive frequencies of 40, 50, 60, and 70 Hz. Maps of shear-wave speed (SWS, in m/s) and loss angle (φ, in rad), representing stiffness and solid-fluid behavior, respectively, were generated using tomoelastography data processing. Histopathological analysis of surgical specimens was used as reference standard in patients. Unpaired t-test, one-way analysis of variance followed by Tukey post hoc analysis, Pearson's correlation coefficient and area under the receiver operating characteristic curve (AUC) with 95%-confidence interval (CI). Significance level of 5%. MR elastography was feasible in all 40 subjects (100% technical success rate). SWS and φ were significantly increased in IBD by 21% and 20% (IBD 1.45 ± 0.14 m/s and 0.78 ± 0.12 rad; healthy volunteers 1.20 ± 0.14 m/s and 0.65 ± 0.06 rad), whereas no significant differences were found between ulcerative colitis and Crohn's disease (P=0.74 and 0.90, respectively). In a preliminary assessment, a high diagnostic accuracy in detecting IBD was suggested by an AUC of 0.90 (CI 0.81-0.96) for SWS and 0.84 (CI 0.71-0.95) for φ. In this pilot study, our results demonstrated the feasibility of MR elastography of the gut and showed an excellent diagnostic performance in predicting IBD. 1 TECHNICAL EFFICACY Stage 1. 1 TECHNICAL EFFICACY Stage 1. T1, T2, and T1ρ might be potential biomarkers for assessing liver fibrosis. However, few studies reported the value of them in different animal models. To investigate and compare the performances of T1, T2, and T1ρ for noninvasively staging liver fibrosis in bile duct ligation (BDL) or carbon tetrachloride (CCl ) model. Prospective animal model. Liver fibrosis was induced by BDL or injection of CCl in 120 rats. 11.7T, T1 mapping with 10 repetition times, T2 mapping with 32 echo times, and T1ρ with 10 spin-lock times. T1, T2, and T1ρ were measured and correlated with liver fibrosis stages, as well as the degree of inflammation, steatosis, iron deposition, and the expression of cytokeratin 19. https://www.selleckchem.com/products/bovine-serum-albumin.html The discriminative performance of T1, T2, and T1ρ for staging liver fibrosis was compared. One-way analysis of variance (ANOVA), Spearman's correlation analysis, factorial design ANOVA, and receiver operating characteristic curves (P < 0.05 was considered statistically significant). T1, T2, and T1ρ (BDL rho=0.73, 0.85, 0.68; CCl rho=0.80, 0.29, 0.61) were significantly correlated with liver fibrosis stages, while there was no significant difference in T2 among stage F0-F4 in the CCl model (P=0.204). The area under the curves (AUCs) range of T1, T2, and T1ρ for predicting ≥F1, ≥F2, ≥F3, and F4 were 0.76-0.95, 0.89-0.98, and 0.80-0.94 in the CCl model. For the CCl model, the AUCs range of T1, T2, and T1ρ for predicting ≥F1, ≥F2, ≥F3, and F4 were 0.83-0.95, 0.61-0.74, and 0.73-0.89, respectively. T2 had significantly higher AUC in the BDL model than CCl model for diagnosing liver fibrosis. The most sensitive and accurate method for staging liver fibrosis appeared to be T1 in our animal models followed by T1ρ. T2 may not be suitable for evaluating liver fibrosis. 1 TECHNICAL EFFICACY STAGE 2. 1 TECHNICAL EFFICACY STAGE 2. To understand the impact of professional stressors on nurses' and other health care providers' professional quality of life and moral distress as they cared for patients during the COVID-19 pandemic. Health care providers caring for patients during the COVID-19 pandemic are at increased risk of decreased professional quality of life and increased moral distress. A convergent mixed-methods design and snowball sampling was used to collect survey data (n = 171) and semi-structured interviews (n = 23) among health care providers working in the inpatient setting. Perceived lack of support from executive leadership, access to personal protective equipment and constantly changing guidelines led to decreased professional quality of life and increased moral distress among health care providers. Findings from this study indicate that shared governance, disaster management training and enhanced communication may assist executive leadership to reduce the likelihood of decreased professional quality of life and increased moral distress in front line health care providers.

Recent studies have reported suboptimal up-titration of heart failure (HF) therapies in patients with heart failure and areduced ejection fraction (HFrEF). Here, we report on the achieved doses after nurse-led up-titration, reasons for not achieving the target dose, subsequent changes in left ventricular ejection fraction (LVEF), and mortality. From 2012 to 2018, 378 HFrEF patients with arecent (< 3months) diagnosis of HF were referred to aspecialised HF-nurse led clinic for protocolised up-titration of guideline-directed medical therapy (GDMT). https://www.selleckchem.com/products/ins018-055-ism001-055.html The achieved doses of GDMT at 9months were recorded, as well as reasons for not achieving the optimal dose in all patients. Echocardiography was performed at baseline and after up-titration in 278patients. Of 345 HFrEF patients with afollow-up visit after 9months, 69% reached ≥ 50% of the recommended dose of renin-angiotensin-system (RAS) inhibitors, 73% reached ≥ 50% of the recommended dose of beta-blockers and 77% reached ≥ 50% of the recommended dose of mineralocorticoid receptor antagonists. The main reasons for not reaching the target dose were hypotension (RAS inhibitors and beta-blockers), bradycardia (beta-blockers) and renal dysfunction (RAS inhibitors). During amedian follow-up of 9months, mean LVEF increased from 27.6% at baseline to 38.8% at follow-up. Each 5% increase in LVEF was associated with an adjusted hazard ratio of 0.84 (0.75-0.94, p = 0.002) for mortality and 0.85 (0.78-0.94, p = 0.001) for the combined endpoint of mortality and/or HF hospitalisation after amean follow-up of 3.3years. This study shows that protocolised up-titration in anurse-led HF clinic leads to high doses of GDMT and improvement of LVEF in patients with new-onset HFrEF. This study shows that protocolised up-titration in a nurse-led HF clinic leads to high doses of GDMT and improvement of LVEF in patients with new-onset HFrEF. National medical/surgical organizations have recommended the use of neoadjuvant endocrine therapy (NET) to bridge surgery delay of weeks to months for patients with hormone receptor positive (HR+) breast cancer during the ongoing coronavirus disease 2019 (COVID-19) pandemic. The effects of NET of varying durations on pathologic response are unclear. Using the National Cancer Database (NCDB), we evaluated objective response to short (< 9 weeks), moderate (9-27 weeks), and long (> 27 weeks) duration of NET. The study cohort included female patients diagnosed with nonmetastatic invasive HR+ breast cancer, stratifying by those who received NET versus no NET between 2004 and 2016. Pathologic response was grouped into four categories (complete, downstaged, stable, upstaged) by comparing clinical and pathologic staging data. Objective response to NET included complete, downstaged, and stable pathologic response. Clinical characteristics were compared using χ and analysis of variance (ANOVA) tests. Multivariable logistic regression was used to determine factors associated with NET use and objective response according to NET duration. A minority (1.2%) received NET in our cohort. Factors associated with NET use included older age, non-Black patients, more advanced clinical stage, higher comorbidity score, government insurance, and lobular histology. Objective response rate (ORR) was 56.7%, 52.1%, and 49.0% after short, moderate, and long NET duration, respectively. Short NET duration did not result in an inferior ORR. Future study to evaluate the interaction between surgery delay and NET use on clinical outcome will provide insights into the safety of NET to bridge potential surgery delay in patients with HR+ breast cancer. Short NET duration did not result in an inferior ORR. Future study to evaluate the interaction between surgery delay and NET use on clinical outcome will provide insights into the safety of NET to bridge potential surgery delay in patients with HR+ breast cancer. Although laparoscopic distal pancreatectomy (LDP) versus open approaches (ODP) for pancreatic adenocarcinoma (PDAC) is associated with reduced morbidity, its impact on optimal adjuvant chemotherapy (AC) utilization remains unclear. Furthermore, it is uncertain whether oncologic resection quality markers are equivalent between approaches. The National Cancer Database (NCDB) was queried between 2010 and 2016 for PDAC patients undergoing DP. Effect of LDP vs ODP and institutional case volumes on margin status, hospital stay, 30-day and 90-day mortality, administration of and delay to AC, and 30-day unplanned readmission were analyzed using binary and linear logistic regression. Cox multivariable regression was used to correct for confounders. The search yielded 3411 patients; 996 (29.2%) had LDP and 2415 (70.8%) had ODP. ODP had higher odds of readmission [odds ratio (OR) 1.681, p = 0.01] and longer hospital stay [β 1.745, p = 0.004]. No difference was found for 30-day mortality [OR 1.689, p = 0.303], 90-dachieve best possible cancer outcomes.The MD Anderson Hospital for Cancer Research (as it was named in 1946) incorporated pioneering changes that set new standards in hospital design, construction, and function. It is remarkable that surgeon R. Lee Clark, the new Director of the MD Anderson Hospital, and with no previous experience in hospital construction, personally led the design and supervision of a world class medical care and research facility. This is the untold story of his leadership and his diligence visiting hospitals and cancer facilities in America and Europe, his clever hiring, his supervision of the architectural firms (through 23 versions of architectural plans), his adaptability to the market when building costs were skyrocketing, and his extraordinary ability in raising enormous funds from private, state, and federal sources. He was such a creative genius in his inaugural building project that the new MD Anderson "cancer station" was described by national magazines as totally unique in its design that set new standards in cancer care delivery. With his typical determination, enthusiasm, and creative approach to problem-solving, Clark embarked on this building project in 1946 with a budget of $1,750,000, expecting to complete this project in 2 to 3 years. In fact, the entire project took 8 years and cost five times more than the original estimate, at almost $9,000,000! The process took 2 years for Dr. Clark to visit more than 30 cancer facilities and many academic hospitals in America and in Europe, 2 years of architectural planning, and 4 years of construction. When MD Anderson opened its doors in 1954, it was described by national magazines as "one of the most modern hospitals in the nation."

orded between countries wıth Cypriot students reporting hıgher level of knowledge than the Greek students in most of the dimensions. CONCLUSıON The findings revealed the gap between theory and practice and the need for collaboration between the two settings. Also, students reported relatively higher knowledge with regards to the technical aspects of patient safety. Still, they were less knowledgable about the sociocultural aspects of the patient, such as working in teams. Postoperative symptomatic anastomotic leakage (AL) is a serious complication after low anterior resection (LAR) for rectal cancer. AL can potentially affect short-term patient outcomes and long-term prognosis. This study aimed to explore the risk factors and long-term survival of symptomatic AL after laparoscopic LAR for rectal cancer. From May 2009 to May 2015, 298 consecutive patients who underwent laparoscopic LAR for rectal cancer with or without a defunctioning stoma were included in this study. Univariate and multivariate logistic regression analyses were used to explore independent risk factors for symptomatic AL. Survival analysis was performed using Kaplan-Meier curves, and log-rank tests were used for group comparisons. Among the 298 patients enrolled in this study, symptomatic AL occurred in eight (2.7%) patients. The univariate analysis showed that age of ≤65 years (P = 0.048), neoadjuvant therapy (P = 0.095), distance from the anal verge (P = 0.078), duration of operation (P = 0.001), and pathological tumor (T) category (P = 0.004) were associated with symptomatic AL. The multivariate analysis demonstrated that prolonged duration of operation (P = 0.010) was an independent risk factor for symptomatic AL after laparoscopic LAR for rectal cancer. No statistically significant differences were observed in the 3-year (P = 0.785) and 5-year (P = 0.979) overall survival rates. A prolonged duration of operation increased the risk of symptomatic AL after laparoscopic LAR for rectal cancer. An impact of symptomatic AL on a long-term survival was not observed in this study; however, further studies are required.

Clinical signs of heat in bitches that have been previously spayed are often associated with the presence of ovarian remnant syndrome. The inclusion of exogenous estrogens as a differential diagnosis in this regard is often ignored and may lead to misinterpretation of the case. Herein, we report a case of exogenous estrogen exposure over several months to a 6.5-year-old spayed crossbred bitch, weighing 8.4 kg. The bitch presented in the clinic because of suspected ovarian remnant syndrome. Castration was performed within the first 6 months after birth. Important endocrine parameters measured at the first appointment were Anti-Müllerian hormone (< 0.01 ng/mL), progesterone (0.36 ng/mL), estradiol-17ß (20.7 pg/mL), and luteinizing hormone (< 0.1 ng/mL). After an extensive conversation with the owner, it was revealed that she was using an estrogen spray because of severe menopausal symptoms. After the owner stopped using this spray, the symptoms of the bitch disappeared. Therefore, the uptake of estrogens should be a differential diagnosis for symptoms of the ovarian remnant syndrome. A detailed anamnesis is crucial to identify the source of estrogen in the environment of the affected bitch.

Long-term cyclic tensile testing with equine palmar/plantar tendons have not yet been performed due to problems in fixing equine tendons securely and loading them cyclically. It is well established that the biomechanical response of tendons varies during cyclic loading over time. The aim of this study was to develop a clamping device that enables repetitive cyclic tensile testing of equine superficial digital flexor tendon for at least 60 loading cycles and for 5 min. A novel cryo-clamp was developed and built. Healthy and collagenase-treated pony SDFTs were mounted in the custom-made cryo-clamp for the proximal tendon end and a special clamping device for the short pastern bone (os coronale). Simultaneously with tensile testing, we used a biplanar high-speed fluoroscopy system (FluoKin) to track tendon movement. The FluoKin system was additionally validated in precision measurements. During the cyclic tensile tests of the SDFTs, the average maximal force measured was 325 N and 953 N for a length variatiopy seems an appropriate and highly precise measurement tool for analysis of tendon behaviour under repetitive load in equine SDFTs. In this study, a good performing clamping technique for equine tendons under repetitive cyclic loading conditions is described. The presented cryo-clamps were tested up to 50 min duration and up to the machine maximal capacity of 10 kN. With the possibility of repetitive loading a stabilization of the time-force-curve and changes of hysteresis and creep became obvious after a dozen cycles, which underlines the necessity of repetitive cyclical testing. Furthermore, biplanar high-speed fluoroscopy seems an appropriate and highly precise measurement tool for analysis of tendon behaviour under repetitive load in equine SDFTs. Exposure to air pollution exerts direct effects on respiratory organs; however, molecular alterations underlying air pollution-induced pulmonary injury remain unclear. In this study, we investigated the effect of air pollution on the lung tissues of Sprague-Dawley rats with whole-body exposure to traffic-related PM (particulate matter < 1 μm in aerodynamic diameter) pollutants and compared it with that in rats exposed to high-efficiency particulate air-filtered gaseous pollutants and clean air controls for 3 and 6 months. Lung function and histological examinations were performed along with quantitative proteomics analysis and functional validation. Rats in the 6-month PM -exposed group exhibited a significant decline in lung function, as determined by decreased FEF and FEV /FVC; however, histological analysis revealed earlier lung damage, as evidenced by increased congestion and macrophage infiltration in 3-month PM -exposed rat lungs. https://www.selleckchem.com/products/amg-232.html The lung tissue proteomics analysis identified 2673 proteins that highlighted the differential dysregulation of proteins involved in oxidative stress, cellular metabolism, calcium signalling, inflammatory responses, and actin dynamics under exposures to PM and gaseous pollutants.

Plant pathogens and their hosts undergo adaptive changes in managed agricultural ecosystems, by overcoming host resistance, but the underlying genetic adaptations are difficult to determine in natural settings. Verticillium dahliae is a fungal pathogen that causes Verticillium wilt on many economically important crops including lettuce. We assessed the dynamics of changes in the V. dahliae genome under selection in a long-term field experiment. In this study, a field was fumigated before the Verticillium dahliae race 1 strain (VdLs.16) was introduced. A derivative 145-strain population was collected over a 6-year period from this field in whicha seggregating population of lettuce derived from Vr1/vr1 parents were evaluated. We de novo sequenced the parental genome of VdLs.16 strain and resequenced the derivative strains to analyze the genetic variations that accumulate over time in the field cropped with lettuce. Population genomics analyses identified 2769 single-nucleotide polymorphisms (SNPs) and 750 insertion/deletions (In-Dels) in the 145 isolates compared with the parental genome. Sequence divergence was identified in the coding sequence regions of 378 genes and in the putative promoter regions of 604 genes. Five-hundred and nine SNPs/In-Dels were identified as fixed. The SNPs and In-Dels were significantly enriched in the transposon-rich, gene-sparse regions, and in those genes with functional roles in signaling and transcriptional regulation. Under the managed ecosystem continuously cropped to lettuce, the local adaptation of V. dahliae evolves at a whole genome scale to accumulate SNPs/In-Dels nonrandomly in hypervariable regions that encode components of signal transduction and transcriptional regulation.

Atypical meningiomas exhibit a high tendency for tumor recurrence even after multimodal therapy. Information regarding recurrence patterns after additive radiotherapy is scarce but could improve radiotherapy planning and therapy decision. We conducted an analysis of recurrence patterns with regard to target volumes and dose coverage assessing target volume definition and postulated areas of tumor re-growth origin. https://www.selleckchem.com/products/bgb-3245-brimarafenib.html Prognostic factors contributing to relapse were evaluated. The clinical outcome of patients who had completed additive, somatostatin receptor (SSTR)-PET/CT-based fractionated intensity-modulated radiotherapy for atypical meningioma between 2007 and 2017 was analyzed. In case of tumor recurrence/progression, treatment planning was evaluated for coverage of the initial target volumes and the recurrent tumor tissue. We proposed a model evaluating the dose distribution in postulated areas of tumor re-growth origin. The median of proliferation marker MIB-1 was assessed as a prognostic factor for locaor dose escalation. The model showed adequate target volume and relative dose distribution but absolute dose appears lower in recurrent tumors without reaching statistical significance. This might provide a rationale for dose escalation studies. Biological factors such as MIB-1 might aid patients' stratification for dose escalation. Women are representing an increasing share of the labor force, thus, raising the need to accommodate breastfeeding working mothers at the workplace. While there is an emerging body of evidence supporting the positive influence of workplace lactation programs on breastfeeding outcomes, there is a lack of literature on the mechanisms underlying those interventions. Aims of this realist review were three-fold to uncover underlying mechanisms, determine who benefits the most from such interventions and important contextual factors influencing uptake. Purposive bibliographic searches on Medline, Web of Science Core Collection, CINAHL, Global Health, LILACS, Global Index Medicus, Business Source Complete, Proquest Dissertations and Theses and Open Access Theses and Dissertations were conducted to identify relevant publications. Included publications (qualitative and quantitative) described interventions aiming to improve the breastfeeding behavior of working mothers, that were initiated by the employer, reporteness of the intervention(s) available among working mothers as well as their work environment, change the workplace culture, foster manager/supervisor support and co-workers support, provide enough time and adequate space and facilities for women to breastfeed or express breastmilk during the workday. In order to be effective, workplace breastfeeding interventions need to raise awareness of the intervention(s) available among working mothers as well as their work environment, change the workplace culture, foster manager/supervisor support and co-workers support, provide enough time and adequate space and facilities for women to breastfeed or express breastmilk during the workday. Rational drug use requires that patients receive and take medication appropriately. Though the process of diagnosis and pharmaceutical care is complex, World Health Organization (WHO)/international network for rational use of drugs (INRUD) core drug use indicators investigate drug use to minimize the hazardous effect of the drug and enhance the wise use of scares resources. This study assessed drug use patterns in health centers of Dessie town using WHO/INRUD indicators. A cross-sectional study was conducted in public health centers of Dessie town. Data were retrospectively collected from 1500 prescriptions dispensed from January 1, 2018, to December 31, 2018 using WHO data collection tool to assess prescribing indicators. For patient care and health facility indicators, 600 patients and 3 health centers were prospectively reviewed. Systematic random sampling was used to select samples. Data were analyzed using the Statistical Package for the Social Sciences version 20. The average number of drugs per encounter was 2.
