The objective of this study was to evaluate the effects of the consumption of Minas Frescal cheese (2 g for 15 d) produced with pasteurized milk or milk subjected to ohmic heating on the health variables (biochemical, hematological, and uric acid levels) of rats, as well as on the identity variables and proteolysis indices of cheese. Three groups of rats (n = 6 per group) were studied, as follows control group, without cheese consumption (CON), rats fed Minas Frescal cheese produced with milk pasteurized by conventional technology (PC, 72 to 75°C for 15 s), and rats fed Minas Frescal cheese produced with milk subjected to ohmic heating (OHC, 8 V/cm, 72 to 75°C for 15 s). Ohmic heating did not alter the macronutrient levels (moisture, fat, protein) of the cheeses, but an increase in the proteolysis index was observed. For both cheeses, no significant differences were observed for feed intake (139 to 143 g/d), water consumption (196 to 206 mL/d), or final animal weight (236 to 252 g), and no changes were detected in hematological variables (counts of red blood cells, hemoglobin, leukocytes, and platelets) or levels of potassium, calcium, magnesium, urea, creatinine, total cholesterol, high-density lipoprotein cholesterol, blood glucose, and bilirubin (total, direct, and indirect) of rats. In addition, both cheeses led to a reduction of serum triglycerides and an increase in monocyte, eosinophil, and basophil levels. However, consumption of OHC resulted in decreased sodium, uric acid, and lymphocyte levels. The present results suggest that ohmic heating in the processing of Minas Frescal cheese has positive effects on the health of healthy rats. Feet and legs disorders influence dairy cattle breeding by their effect on animal welfare, economic losses due to lower production and fertility, costs of treatment, and problems with herd management. In our study, we estimated heritabilities and performed a 2-step GWAS for 3 traits describing hoof health hoof health status defined by a veterinarian (HSV), hoof health status defined by a claw trimmer (HSC), and the total number of hoof disorders (NHD), scored in 1,998 Fleckvieh and 979 Braunvieh cows. The individuals were genotyped with a high-density (HD) panel consisting of 76,934 SNP. For significant genomic regions, the SNP information was enhanced by SNP imputed from the whole-genome sequence of Fleckvieh and Braunvieh bulls from the 1000 Bulls Genome project. The heritabilities were estimated to be 0.035 for HSV, 0.249 for HSC, and 0.279 for NHD. Based on the first-stage GWAS with SNP from the HD panel, 7 significant genomic regions on 6 chromosomes were defined (1) 120 SNP spanning 15,522 bp on BTA1, i causal mutation for HSC was rs134142607 on BTA13, within the exon of C13H20orf194. For NHD, 33 SNP with the highest estimated effect were located on BTA7 within a region of a predicted gene positioned between RIOK2 and RGMB. On BTA14, all significant SNP were located in introns of STK3, which is responsible for the "abnormal gait" phenotype in mice. We analyzed a large number of immune response parameters from quarter milk samples with distinct bacteriological and quarter somatic cell count (qSCC) statuses. Furthermore, we sought to explore and identify displayed immune response patterns in milk samples from mammary glands with nonspecific mastitis. Thus, 92 quarter milk samples from 28 cows were stratified into 4 groups, as follows (1) 49 culture-negative control quarters with a low qSCC (2 × 105 cells/mL; so-called quarters with nonspecific mastitis) from 10 dairy cows; (3) 8 culture-positive quarters with low qSCC (noninflammatory quarters with low qSCC) from 5 dairy cows; and (4) 20 culture-positive quarters with high qSCC (so-called truly infected quarters) from 8 dairy cows. https://www.selleckchem.com/products/ly333531.html Using flow cytometry, we evaluated the percentage of milk neutrophils and their viability, intracellular reactive oxygen species production, phagocytosis, and the expression of CD62L, CD11b, and CD44 for each of the 4 quarter strata. Furthermore, the percentage of monocyte/macrermore, an increase in milk CD4+ T cells was associated with nonspecific mastitis, suggesting an increase in this leukocyte subpopulation is correlated with low bacterial shedding. Our study allows us to go further in our understanding of mammary gland immunity, providing further insights on potential protective mammary gland immunity, which we hypothesize can open new avenues for the development of novel targets that can promote bovine udder health. The objective of this study was to evaluate the protection conferred by lactoferrin, α-lactalbumin, and β-lactoglobulin in cerebral ischemia reperfusion (I/R) injury. Rat pheochromocytoma (PC12) cells were used to construct an oxygen and glucose deprivation model in vitro, and ICR mice underwent carotid artery "ligation-relaxation" to construct a cerebral I/R injury model in vivo. The level of toll-like receptor 4 (TLR4) and downstream factors including nuclear factor-κB, tumor necrosis factor-α, and IL-1β were measured. Metabonomics detection and data mining were conducted to identify the specific metabolic sponsor of the 3 proteins. The results showed that lactoferrin, α-lactalbumin, and β-lactoglobulin protected neurons from cerebral I/R injury by increasing the level of bopindolol and subsequently inhibiting the TLR4-related pathway to different degrees; β-lactoglobulin had the strongest activity of the 3 proteins. In summary, this study is the first to investigate and compare the protective effects of lactoferrin, α-lactalbumin, and β-lactoglobulin in a cerebral stroke model. The results implicate TLR4 as a novel target of the 3 bioactive proteins to prevent cerebral I/R injury. The aim of this study was to evaluate temporal variations in circulating levels of selected hormones and metabolites in commercial dairy goats during the transition period. Blood samples from 940 goats were collected weekly, from -3 to 3 wk relative to delivery, to measure the effects of level of milk production, parity number, and litter size on concentrations of glucose, β-hydroxybutyrate (BHB), fatty acids, and plasma urea nitrogen (PUN). A subset of 80 goats [40 low-yielding (LY, 3.7 L/d)] were selected from the study population to measure the effects of level of milk production on plasma concentration of insulin, prolactin, and growth hormone. Average (±SD) milk yield (from 3 to 30 d in milk), body weight, and body condition score for the study population were 2.4 ± 0.78 L/d, 70 ± 16.0 kg, and 2.5 ± 0.28 units, respectively. Milk yield was moderately correlated with parity number (r = 0.49) but had weak correlation with litter size (r = 0.14). In multiparous but not in primiparous goats, antepartum concentrations of fatty acids and BHB increased with increasing litter size.

The matrix effect was effectively eliminated after the clean-up procedure as confirmed by comparing the ratio of standard curves prepared by standards dissolved in both matrix solvent and 5 mmol/L ammonium acetate in water acetonitrile (955, v/v). The recoveries of these nitrofuran metabolites under the 1 µg/kg, 2 µg/kg and 10 µg/kg spiking levels were between 77.4% and 95.6%. These metabolites after the extraction were stable at 4 °C for 24 h. The validated method was used to analyze the residue level of these nitrofuran metabolites in 25 gelatin Chinese medicines. Results showed that only one Colla Corii Asini sample contained SEM (2.52 µg/kg) and AOZ (6.27 µg/kg), whereas one Testudinis Carapacis et Plastri sample had SEM (1.27 µg/kg) and AMOZ (9.53 µg/kg). INTRODUCTION Sub-optimal use or interpretation of imaging investigations prior to diagnosis of certain cancers may be associated with less timely diagnosis, but pre-diagnostic imaging activity for urological cancer is unknown. METHOD We analysed linked data derived from primary and secondary care records and cancer registration to evaluate the use of clinically relevant imaging tests pre-diagnosis, in patients with bladder and kidney cancer diagnosed in 2012-15 in England. As pre-diagnostic imaging activity increased from background rate 8 months pre-diagnosis, we used logistic regression to determine factors associated with first imaging test occurring 4-8 months pre-diagnosis, considering that such instances may reflect possible missed opportunities for expediting the diagnosis. RESULTS 1963 patients with bladder or kidney cancer had at least one imaging test in the 8 months pre-diagnosis. 420 (21%) of patients had their first imaging test 4-8 months pre-diagnosis, that being ultrasound, CT and X-ray in 48%, 43% and 9% of those cases, respectively. https://www.selleckchem.com/ Factors associated with greater risk of a first imaging test 4-8 months pre-diagnosis were kidney cancer, diagnosis at stages other than stage IV, first imaging having been an X-ray, test requested by GP and absence of haematuria before the imaging request. CONCLUSION About 1 in 5 patients with urological cancers receive relevant first imaging investigations 4-8 months prior to diagnosis, which may represent potential missed diagnostic opportunities for earlier diagnosis. Flavone derivatives have been shown to possess anti-inflammatory properties in various inflammation model systems; however, their underlying molecular mechanisms remain elusive. In this study, a flavone derivative 3',4',5'-trihydroxyflavone (THF; NJK16003) was synthesized, and its anti-inflammatory effects and molecular targets were investigated using in vitro systems and an in vivo colitis model. NJK16003 showed potent anti-inflammatory activities in cell-based assays using macrophages. In vitro enzyme activity assays using various inflammation-related kinases revealed the mammalian target of rapamycin (mTOR) as a possible molecular target. Treatment of RAW264.7 cells with NJK16003 resulted in an increase in light chain 3B protein lipidation and a decrease in p62 protein levels and ribosomal S6 kinase phosphorylation, indicating that NJK16003 induces autophagy through mTOR inhibition. NJK16003 treatment resulted in significant induction of autophagy and suppression of inflammatory responses in intestinal epithelial cells. Autophagy induction has been shown to alleviate colitis by suppressing inflammatory responses and apoptotic cell death of intestinal epithelial cells. Indeed, inflammatory responses and intestinal epithelial cell death in our DSS-induced colitis mouse model were significantly suppressed by NJK16003 treatment. Our results indicate that NJK16003 could suppress inflammation by inducing autophagy through its mTOR inhibitory activity. These results suggest that NJK16003 could be a possible therapeutic agent for the treatment of inflammatory bowel diseases including colitis. Tumor therapeutic vaccines have faced a challenge for effective protection against malignant tumors by inducing tumor-specific CD8+ T cell responses. Here, we designed a DNA vaccine containing a tumor-specific antigen of Dickkopf-1 (DKK-1) and an immune checkpoint of programmed death ligand 1 (PD-L1) delivered by PLGA/PEI nanoparticle-mediated delivery system for multiple myeloma therapy. Murine subcutaneous tumor model established with human DKK1 (hDKK-1)-SP2/0 cells were intramuscularly immunized with PLGA/PEI-pPD-L1/pDDK-1 vaccine and equal amount of control 3 times at 10 day-intervals. Compared with PLGA/PEI-pDKK1 immunization group, PLGA/PEI-pPD-L1/pDKK-1 co-immunization enhanced the induction and mature of CD11c+ DCs and CD8+CD11c+ DCs, and promoted antigen-specific Th1 responses and cytotoxic T lymphocyte (CTL) responses. The reduced tumor volume and weight as well as increased tumor inhibition rate were observed in PLGA/PEI-pPD-L1/pDKK-1 vaccine co-immunization group, indicated that the vaccine could effectively inhibit the tumor growth of multiple myeloma. The anti-tumor activity of PLGA/PEI-pPD-L1/pDKK-1 vaccine was abrogated by CD8 cell depletion accompanied with the reduced percentages of CD8+CD11c+ DCs and CD8+ T cells in the spleen and TILs. These results indicated that the anti-tumor efficacy of PLGA/PEI-pPD-L1/pDKK-1 vaccine was required for CD8+CD11c+ DCs-mediated CD8+ T cell immunity responses. This vaccine strategy may represent a potential and promising approach for hematological malignancy treatment. As a chronic musculoskeletal degeneration disease, osteoarthritis (OA) clinically manifests as joint pain, stiffness and a limited range of movement. OA has affected the life quality of at least one-tenth of the population but lacks satisfactory treatments. α-Bisabolol (BISA) is a small oily sesquiterpene alcohol widely found in essential oils of chamomile (Matricaria recutita), salvia and wood of Candeia and has multiple biological properties, particularly an anti-inflammatory effect. The purpose of this study is to assess the anti-inflammatory and chondroprotective effect of BISA in OA progression and explore its underlying mechanism. We isolated human chondrocytes and treated them with advanced glycation end products (AGEs) to imitate OA progression in vitro. BISA pretreatment suppressed the AGE-induced inflammatory reaction and extracellular matrix (ECM) degeneration by blocking nuclear factor kappa B (NF-κB), p38 and c-Jun N-terminal kinase (JNK) signaling. Moreover, a mouse destabilization of the medial meniscus (DMM) model was established by surgery to investigate BISA protection in vivo.

BACKGROUND Patients experiencing out-of-hospital cardiac arrest (OHCA) and subsequent post-cardiac arrest syndrome are often compromised by multi-organ failure. The Sequential Organ Failure Assessment (SOFA) score has been used to predict clinical outcome of patients requiring intensive care for multi-organ failure. Thus, the assessment of SOFA score is recommended as a criterion for sepsis. Although post-cardiac arrest patients frequently develop sepsis-like status in ICU, there are limited reports evaluating the SOFA score in post-cardiac arrest patients. We investigated the predictive value of the SOFA score in survival and neurological outcomes in patients with post-cardiac arrest syndrome. METHODS A total of 231 cardiovascular arrest patients achieving return of spontaneous circulation (ROSC) were finally extracted from the institutional consecutive database comprised of 1218 OHCA patients transferred to the institution between January 2015 and July 2018. The SOFA score was calculated on admission and after 48h. Predictors of survival and neurological outcome defined as having cerebral-performance-category (CPC) 1 or 2 at 30 days were determined. RESULTS SOFA score was lower in survived patients (5.0 vs 10.0, p less then 0.001) and those with favorable neurological outcome (5.0 vs 8.0, p less then 0.001) as compared with the counterparts. The SOFA score on admission was an independent predictor of survival (OR 0.68, 95% confidence interval [CI] 0.59-0.78; p less then 0.001) and favorable neurological performance (OR 0.79; 95% CI 0.69-0.90; p less then 0.001) at 30 days. Furthermore, a change in SOFA score (48-0h) was predictive of favorable 30-day neurological outcome (OR 0.71, 95% CI 0.60-0.85; p less then 0.001). CONCLUSIONS Evaluation of the SOFA score in the ICU is useful to predict survival and neurological outcome in post-cardiac arrest patients. BACKGROUND Early pregnancy loss (EPL) is a common event in the first trimester, occurring in 15-20% of recognized pregnancies. A common evidence-based medical regimen for EPL management uses the prostaglandin E1 analogue misoprostol 800 mcg self-administered vaginally. The clinical utility of this regimen is limited by suboptimal effectiveness in women with a closed cervical os, with 29% of women with EPL requiring a second dose after three days, and 16% eventually requiring a uterine aspiration procedure. OBJECTIVES To evaluate characteristics associated with treatment success in women receiving medical management with mifepristone-misoprostol or misoprostol alone for early pregnancy loss (EPL). STUDY DESIGN We performed a planned secondary analysis of a randomized trial comparing mifepristone-misoprostol to misoprostol alone for EPL treatment. The published prediction model for success of single-dose vaginal misoprostol included the following variables active bleeding, type of EPL (anembryonic pregnancy or , the only significant predictors of treatment success were mifepristone pretreatment (aOR 2.51, 95% CI 1.43-4.43), and smoking (aOR 2.15, 95% CI 1.03-4.49). CONCLUSION No baseline clinical factors predict success in women undergoing medical management of EPL with misoprostol. Adding mifepristone to the EPL medical management regimen improves treatment success and should be used regardless of baseline clinical characteristics. Symptoms of respiratory involvement are frequently present but overlooked by patients with Myotonic Dystrophy type 1 (DM1). A respiratory symptom checklist was designed to test whether a DM-specifically designed checklist to detect symptoms of respiratory involvement (The Respicheck Questionnaire) could help patients be more aware of their respiratory problems, if any, and help clinicians in identifying potential candidates for intervention. The Respicheck questionnaire was administered to 58 consecutive adult-onset patients with genetically determined DM1 who did not complain of respiratory involvement per history at enrollment. Based on respiratory function test results patients were divided into 3 groups A, (n = 17) having no signs of respiratory involvement; B (n = 13), patients having borderline results on respiratory assessments and having no need for respiratory intervention; C, (n = 28) patients having respiratory impairment requiring intervention. Respiratory test results and Respicheck scores were analyzed. Respicheck total score and subscales correlated positively with global respiratory impairment. Respicheck appears to be able to discriminate between patients having a higher level of respiratory dysfunction from those having a lower risk of respiratory involvement. This might allow to better target efforts and resources in respiratory management in DM1. V.Purpose We evaluated the efficacy and safety of avelumab, an anti-PD-L1 antibody, in patients with metastatic or unresectable colorectal cancer (mCRC) with mismatch repair deficiency (dMMR)/microsatellite instability-high (MSI-H) or POLE mutations. Materials and Methods In this prospective, open-label, multicenter phase II study, 33 patients with mCRC harboring dMMR/MSI-H or POLE mutations after failure of ≥1st-line chemotherapy received avelumab 10 mg/kg every 2 weeks. https://www.selleckchem.com/products/pacritinib-sb1518.html dMMR/MSI-H was confirmed with immunohistochemical staining (IHC) by loss of expression of MMR proteins or polymerase chain reaction (PCR) for microsatellite sequences. POLE mutation was confirmed by next-generation sequencing (NGS). The primary endpoint was the objective response rate (ORR) by Response Evaluation Criteria in Solid Tumors version 1.1. Results The median age was 60 years, and 78.8% were male. Thirty patients were dMMR/MSI-H and three had POLE mutations. The ORR was 24.2%, and all of the responders were dMMR/MSI-H. For 21 patients with MSI-H by PCR or NGS, the ORR was 28.6%. At a median follow-up duration of 16.3 months, median progression-free survival and overall survival were 3.9 and 13.2 months in all patients, and 8.1 months and not reached, respectively, in patients with MSI-H by PCR or NGS. Dose interruption and discontinuation due to treatment-related adverse events occurred in 4 and 2 patients, respectively, with no treatment-related deaths. Conclusion Avelumab displayed antitumor activity with manageable toxicity in patients with previously treated mCRC harboring dMMR/MSI-H. Diagnosis of dMMR/MSI-H with PCR or NGS could be complementary to IHC to select patients who would benefit from immunotherapy.

Furthermore, Slit2 overexpression attenuated the increases in myofilament-associated PKCs and phosphorylation of cTnI at Ser43 in the post-IR myocardium. The myofilament calcium sensitivity and actomyosin MgATPase activity were preserved in the post-IR Slit2 myocardium. Conclusion Our work demonstrates that Slit2 inhibits inflammatory responses and maintains myofilament contractile properties, thus contributing, at least in part, to the prevention of structural and functional damage during IR.

Meanwhile, R. rugosa and C. morifolium are important cash plants in Kunming, South China. We focus on the population performance of these two thrips species on these three host plants with or without repeated exposure to imidacloprid in Kunming. https://www.selleckchem.com/products/sch58261.html In the field, the population numbers of F. occidentalis developed faster and were larger on these three sampled host plants, especially under imidacloprid exposure, compared with F. intonsa. The activity of the detoxifying enzymes (CarE, AchE, and MFO) and the antioxidant enzymes (CAT and POD) in both thrips species were significantly enhanced under imidacloprid exposure, whereas the activities of SOD in both thrips were significantly decreased on these three host plants, compared with the control. Overall, enzyme activity of F. occidentalis showed a greater increase than that observed in F. intonsa in most cases, which could be exploited in further studies on thrips resistance management.

If it can inhibit the activity of glycolysis-related enzymes and control the energy metabolism of tumor, it can be targeted for the treatment of malignant tumor. The target proteins phosphoglycerate kinase 2 (PGK2), glycerol-3-phosphate dehydrogenase (GPD2), and glucose-6-phosphate isomerase (GPI) were screened by combining transcriptome, proteomics, and reverse docking. We detected the binding constant of the active compound using microscale thermophoresis (MST). It was found that esculetin bound well with three potential target proteins. Esculetin significantly inhibited the rate of glycolysis, manifested by differences of cellular lactate production and glucose consumption in HepG2 cells with or without esculetin. It was found that GPD2 bound strongly to GPI, revealing the direct interaction between the two glycolysis-related proteins. Animal tests have further demonstrated that esculetin may have anticancer effects by affecting the activity of PGK2, GPD2, and GPI. The results of this study demonstrated that esculetin can affect the glucose metabolism by binding to glycolytic proteins, thus playing an anti-tumor role, and these proteins which have direct interactions are potential novel targets for tumor treatment by esculetin.

The hypolipidemic effects of statins in the liver are mainly regulated by organic anion transporting polypeptides (OATPs), and the expression of OATPs is regulated by nuclear receptors. Berberine has been reported to affect nuclear receptors. However, whether berberine affects the uptake of statins by regulating nuclear receptor-mediated expression of OATPs remains to be determined. The aim of this study was to investigate the effects of berberine on the expression of OATP1B1 in HepG2 and explore the underlying mechanism. In HepG2 cells, 10-50 μM berberine significantly increased the uptake of rosuvastatin by inducing the expression of OATP1B1 mRNA and protein. Dual-Luciferase reporter assay showed that luciferase activity of hFXR and hLXRα activated OATP1B1 promoter was increased by 2.5-50 μM berberine in a concentration-dependent manner, with half-maximal effective concentration (EC50) of 12.19 ± 0.86 and 32.15 ± 2.32 μM, respectively. In addition, after silencing FXR or LXRα by small interfering RNA (siRNA), berberine-induced OATP1B1 expression was significantly attenuated. Western blot analysis of FXR and LXRα protein levels in the cytoplasm and nucleus of HepG2 cells after treatment with berberine showed that berberine induced nuclear translocation and activation of FXR and LXRα. In conclusion, berberine-induced nuclear translocation of FXR and LXRα could activate OATP1B1 promoter, resulting in enhanced expression of OATP1B1 and increased uptake of rosuvastatin.

However, no effective therapy is available now. Aldehyde dehydrogenase 2 (ALDH2) enzyme has been shown to protect the heart from aldehyde toxicity such as 4-hydroxy-2-nonenal (4-HNE) and oxidative stress. In this study, we evaluated the effect of enhanced activity or expression of ALDH2 on post-cardiac arrest myocardial dysfunction and survival in a rat cardiac arrest model. Furthermore, we elucidated the underlying mechanisms with a focus on mitochondrial reactive oxygen species (ROS) production in a cell hypoxia/reoxygenation model. A total of 126 rats were used for the ALDH2 activation or cardiac overexpression of ALDH2 studies. Randomization was done 10 min before the respective agonist injection or in vivo gene delivery. We showed that enhanced activity or expression of ALDH2 significantly improved contractile function of the left ventricle and survival rate in rats subjected to cardiac arrest-cardiopulmonary resuscitation procedure. Moreover, ALDH2 prevented cardiac arrest-induced cardiomyocyte death from apoptosis and mitochondrial damage. Mechanistically, 4-HNE, a representative substrate of ALDH2, was dominantly increased in the hypoxia/reoxygenation-exposed cardiomyocytes. Direct addition of 4-HNE led to significantly augmented succinate accumulation and mitochondrial ROS production. Through metabolizing 4-HNE, ALDH2 significantly inhibited mitochondrial ROS production. Our findings provide compelling evidence of the cardioprotective effects of ALDH2 and therapeutic targeting this enzyme would provide an important approach for treating post-cardiac arrest myocardial dysfunction.

ics published by John Wiley & Sons Ltd.BACKGROUND Rhabdomyosarcoma (RMS) in infants is a particular entity with various clinical presentations and outcomes. To better understand the clinical heterogeneity of RMS in infants, an integrative clinical, histological, and molecular analysis was performed. METHODS From 1989 to 2015, 37 infants aged less than 6 months with a diagnosis of RMS and archival tumor materials were identified in France. Clinical data, central pathologic review, and molecular profile including RNA sequencing were analyzed. RESULTS Nineteen patients (51%) had embryonal RMS (ERMS) (including three highly differentiated ERMS with PTCH deletion), eight (22%) had spindle cell RMS (SRMS) (three VGLL2-, one NTRK-, and two (B)RAF-fusions), six (16%) had alveolar RMS (ARMS) (all FOXO1- or PAX3-fusion), two had unclassified RMS, and two poorly differentiated RMS were retrospectively diagnosed as rhabdoid tumors (RT) with loss of INI1 expression. The two RT patients died of rapid disease progression. Five-year event-free (EFS) and overall survival (OS) for RMS were 62% (95%CI, 47-82) and 52% (95%CI, 37-72). https://www.selleckchem.com/products/ana-12.html Eleven patients (31%) relapsed and four (11%) had primary refractory disease (all ERMS). In univariate analysis, EFS and OS were only associated with histology subtype, with 100% survival of known fusion-positive SRMS. RNA cluster expression showed three main clusters ARMS, ERMS, and "VGLL2-fusion" cluster, consisting of SRMS and ERMS. CONCLUSIONS Biopathology findings from this study support the different prognosis of infantile RMS. New fusion-positive SRMS has a very good outcome which may allow more conservative treatment in the future. © 2019 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.BACKGROUND AND PURPOSE Larotrectinib is an FDA-approved oral small-molecule inhibitor for treatment of neurotrophic tropomyosin receptor kinase (NTRK) fusion-positive cancer. We here investigated the functions of the multidrug efflux transporters ABCB1 and ABCG2, the SLCO1A/1B (OATP1A/1B) uptake transporters and the multispecific drug-metabolizing enzyme CYP3A in larotrectinib pharmacokinetic behavior. EXPERIMENTAL APPROACH In vitro, transepithelial drug transport and uptake assays were performed. In vivo, larotrectinib (10 mg/kg) was administered orally to relevant genetically modified mouse models. Cell medium, plasma samples and organ homogenates were measured by a sensitive and specific liquid chromatography-tandem mass spectrometric larotrectinib assay. KEY RESULTS In vitro, larotrectinib was avidly transported by human (h)ABCB1 and mouse (m)Abcg2 efficiently by hABCG2, and modestly by hOATP1A2. In vivo, both mAbcb1a/1b and mAbcg2 markedly limited larotrectinib oral availability and brain and testis accumulation (by 2.1-, 10.4-, and 2.7-fold, respectively), with mAbcb1a/1b playing a more prominent role. mOatp1a/1b also restricted larotrectinib oral availability (by 3.8-fold) and overall tissue exposure, apparently by mediating substantial uptake into the liver, thus likely facilitating hepatobiliary excretion. Additionally, larotrectinib is an excellent substrate of CYP3A, which restricts the oral availability of larotrectinib, and hence its tissue exposure. CONCLUSIONS AND IMPLICATIONS ABCG2 and especially ABCB1 limit the oral availability and brain and testis penetration of larotrectinib, while OATP1A/1B transporters restrict its systemic exposure by mediating hepatic uptake, thus allowing hepatobiliary excretion. CYP3A-mediated metabolism can strongly limit larotrectinib oral availability and hence its tissue concentrations. These insights may be useful in the further clinical development of larotrectinib.

The current study involved a pilot, parallel-group, randomized controlled trial of a video self-help intervention for primary care patients based on acceptance and commitment therapy (ACT). The intervention, called LifeStories, consisted of storytelling vignettes of patients describing their use of ACT-consistent coping skills for depression. Primary care patients were recruited to determine feasibility, acceptability, and potential clinical effects of the intervention. Twenty-one participants were assigned to use LifeStories over a period of 4 weeks, and 19 participants were assigned to an attention-matched comparison group. Qualitative feedback indicated that participants using LifeStories found the intervention to be engaging and useful in transmitting key ACT principles. Furthermore, those receiving LifeStories rated their level of "transportation" or immersion in the videos higher than the control group. Both conditions showed large improvements in levels of depression at a 12-week follow-up. There were no significant differences in symptom outcomes between groups; however, because this was a pilot study, it was not powered to detect differences between interventions. Both conditions additionally showed smaller effect size changes in psychological flexibility, a key ACT mechanism. The results suggest LifeStories to be a feasible and acceptable psychological intervention that may improve depression, and further research is warranted to determine its effectiveness as part of a stepped-care approach to treating depression in primary care. © 2020 John Wiley & Sons, Ltd.BACKGROUND Currently, the prognosis of kidney cancer depends mainly on the pathological grade or tumor stage. Clinicians have few effective tools that can personalize and adequately evaluate the prognosis of kidney cancer patients. METHODS A total of 70 481 kidney cancer patients were selected from the Surveillance, Epidemiology, and End Results database, among which patients diagnosed in 2005-2011 (n = 42 890) were used to establish nomograms for overall survival (OS) and cancer-specific survival (CSS), and those diagnosed in 2012-2015 (n = 24 591) were used for external validation. Univariate and multivariate Cox analyses were used to determine independent prognostic factors. Concordance index (C-index), receiver operating characteristic curve, and calibration curve were used to evaluate the predictive capacity of the nomograms. We further reduced subgroup classification and used propensity score matching to balance clinical informations, and analyzed the effect of other variables on survival. We established a new kidney cancer prognostic score system based on the effect of all available variables on survival.

tp//mhealth.jmir.org), 15.04.2020.BACKGROUND Video-based health care can help address access gaps for patients and is rapidly being offered by health care organizations. https://www.selleckchem.com/products/Cediranib.html However, patients who lack access to technology may be left behind in these initiatives. In 2016, the US Department of Veterans Affairs (VA) began distributing video-enabled tablets to provide video visits to veterans with health care access barriers. OBJECTIVE This study aimed to evaluate veterans' experiences with VA-issued tablets and identify patient characteristics associated with preferences for video visits vs in-person care. METHODS A baseline survey was sent to the tablet recipients, and a follow-up survey was sent to the respondents 3 to 6 months later. Multivariate logistic regression was used to identify patient characteristics associated with preferences for care, and we examined qualitative themes around care preferences using standard content analysis methods for coding the data collected in the open-ended questions. RESULTS Patient-reported access barriers cens in access to care, perceived differential quality of care, feasibility of obtaining necessary care, and technology-related challenges. CONCLUSIONS Many recipients of VA-issued tablets report that video care is equivalent to or preferred to in-person care. Results may inform efforts to identify good candidates for virtual care and interventions to support individuals who experience technical challenges. ©Cindie Slightam, Amy J Gregory, Jiaqi Hu, Josephine Jacobs, Tolessa Gurmessa, Rachel Kimerling, Daniel Blonigen, Donna M Zulman.

The early obstetric ultrasound assessment before 14 weeks is considered the best reference to assist in determining gestational age (GA), with an accuracy of ±5 to 7 days. However, this information is limited in many settings worldwide. OBJECTIVE The aim of this study is to analyze the association between the obstetric interventions during childbirth and the quality of GA determination, according to the first antenatal ultrasound assessment, which assisted the calculation. METHODS This is a hospital-based cohort study using medical record data of 2113 births at a perinatal referral center. The database was separated into groups and subgroups of analyses based on the reference used by obstetricians to obtain GA at birth. Maternal and neonatal characteristics, mode of delivery, oxytocin augmentation, and forceps delivery were compared between groups of pregnancies with GA determination at , Juliano De Souza Gaspar, Gabriela Luiza Nogueira Vitral, Vitor Barbosa Abrantes, Ingrid Michelle Fonseca De-Souza, Maria Tereza Silveira Moreira, Regina Amélia Lopes Pessoa Aguiar.

However, for a minority of parents, such searches may become excessive and distressing. Little is known about excessive web-based searching by parents for information regarding their children's health. OBJECTIVE This study aimed to develop and validate an instrument designed to assess parents' web-based health information searching behavior, the Children's Health Internet Research, Parental Inventory (CHIRPI). METHODS A pilot survey was used to establish the instrument (21 items). CHIRPI was validated online in a second sample (372/384, 96.9% mothers; mean age 32.7 years, SD 5.8). Item analyses, an exploratory factor analysis (EFA), and correlations with parents' perception of their children's health-related vulnerability (Child Vulnerability Scale, CVS), parental health anxiety (modified short Health Anxiety Inventory, mSHAI), and parental cy15.04.2020.BACKGROUND Nearly half of the patients with breast cancer experience clinically significant mental distress within the first year of receiving their cancer diagnosis. There is an urgent need to identify scalable and cost-efficient ways of delivering empirically supported mental health interventions to patients with breast cancer. OBJECTIVE The aim of this study was to evaluate the feasibility of in-clinic recruitment for a mobile phone app study and to evaluate the usability and preliminary impact of a suite of mental health apps (IntelliCare) with phone coaching on psychosocial distress symptoms in patients recently diagnosed with breast cancer. METHODS This pilot study adopted a within-subject, 7-week pre-post study design. A total of 40 patients with breast cancer were recruited at a US National Cancer Institute-designated clinical cancer center.

Yet only 45% of technology interventions are theoretically based, and the acceptability mechanisms have been insufficiently studied. Acceptability and acceptance theories have provided interesting insights, particularly the unified theory of acceptance and use of technology 2 (UTAUT2). In several studies, the psychometric qualities of acceptability scales have not been well demonstrated. OBJECTIVE The aim of this study was to adapt the UTAUT2 to the electronic health (eHealth) context and provide a preliminary validation of the eHealth acceptability scale in a French sample. METHODS In line with the reference validation methodologies, we carried out the following stages of validating the scale with a total of 576 volunteers translation and adaptation, dimensionality tests, reliability tests, and construct validity tests. We used confirmatory factor analysis to validate a 22-item instrument with 7 subscales Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions, Hedonic Motivation, Price Value, and Habit.

2%). There was significant variation in airway device use between centres. The intubation rate ranged between 21% and 90% while supraglottic airway use varied between 1% and 45%. The choice of tracheal intubation vs. supraglottic airway as the second advanced airway device was not associated with immediate survival from the resuscitation attempt (odds ratio 0.81; 95% confidence interval 0.35-1.8). Conclusion There is wide variation in airway device use during resuscitation after IHCA. Only half of patients are intubated before return of spontaneous circulation and many are managed without an advanced airway. Further investigation is needed to determine optimal airway device management strategies during resuscitation following IHCA.Objectives Given the high need and the absence of specific antivirals for treatment of COVID-19 (the disease caused by severe acute respiratory syndrome-associated coronavirus-2 [SARS-CoV-2]), human immunodeficiency virus (HIV) protease inhibitors are being considered as therapeutic alternatives. Methods Prezcobix/Rezolsta is a fixed-dose combination of 800 mg of the HIV protease inhibitor darunavir (DRV) and 150 mg cobicistat, a CYP3A4 inhibitor, which is indicated in combination with other antiretroviral agents for the treatment of HIV infection. There are currently no definitive data on the safety and efficacy of DRV/cobicistat for the treatment of COVID-19. The in vitro antiviral activity of darunavir against a clinical isolate from a patient infected with SARS-CoV-2 was assessed. Results DRV showed no antiviral activity against SARS-CoV-2 at clinically relevant concentrations (EC50 > 100 μM). Remdesivir, used as a positive control, demonstrated potent antiviral activity (EC50 = 0.38 μM). Conclusions Overall, the data do not support the use of DRV for the treatment of COVID-19.Disintegration is the first event in the bioavailability cascade after the ingestion of immediate release tablets. Although the influence of various physico-chemical parameters of media on tablet disintegration has been investigated in depth, the role of temperature has received much less attention. Probing the effect of temperature on disintegration is important in order to understand if previous in vitro studies conducted at room temperature can be related to those performed at body temperature. Moreover, from a biorelevant point of view, a tablet could be co-ingested with a cold or hot drink, inducing transient variations of intragastric temperature; state of fever could also elevate body temperature. Here, we studied the effect of temperature on disintegration of directly compressed tablets made of disintegrants alone and in combination with commonly used diluents and binders, using an image analysis technique as well as a compendial disintegration apparatus. Our results indicate that temperature in the range of 23°C to 41°C had a positive effect on disintegration tablets tested at higher temperatures exhibited up to 2.9-fold faster disintegration than those tested at lower temperatures. The extent of temperature effect on disintegration time was significantly influenced by the composition of the formulations. Overall, the findings of this study suggest that disintegration results obtained in vitro at room temperature can be qualitatively, but not quantitatively, compared to those obtained at body temperature. We also speculate that although temperature had a moderate influence on in vitro disintegration, the magnitude of this effect is unlikely to impact the oral bioavailability in vivo.Recurrent outbreaks of Crimean-Congo hemorrhagic fever (CCHF) virus infection in different parts of world are a major global health concern. The CCHF viral infection is associated with severe hemorrhagic fevers and mortality up to 40%. More than 30 countries in Asia, Europe and Africa are affected with CCHF infection. Prevention of infection through vaccine becomes more important when no effective antiviral and associated therapies are available. Further ticks play a crucial role in maintenance and transmission of CCHFV. Therefore, the control of transmission by ticks is warranted for ultimate prevention of outbreak. The study employed a series of immunoinformatics approaches to design novel multiepitope vaccine targeting highly immunodominant epitopes of major structural proteins (Nucleoprotein and Glycoprotein complex) of CCHFV. Vaccine was designed by incorporating linear and conformational B cell, helper and cytotoxic T cell epitopes from these crucial immunogenic proteins adjoined with appropriate linkers and adjuvant. This vaccine construct was also complemented with a highly immunogenic and conserved protective tick salivary antigen named subolesin to impart dual activity as a unique transmission blocking vaccine. The B-cell peptides were also experimentally validated. The designed vaccine was further in silico validated for its physiochemical properties, allergenicity and immunogenicity etc. The proposed candidate vaccine construct has the potential to function both as a vaccine against CCHF virus as well as a universal anti-tick vaccine.The coronavirus disease 2019 surge in New York City created an increased demand for palliative care (PC) services. In staff-limited settings such as safety net systems, and amid growing reports of health care worker illness, leveraging help from less-affected areas around the country may provide an untapped source of support. A national social media outreach effort recruited 413 telepalliative medicine volunteers (TPMVs). After expedited credentialing and onboarding of 67 TPMVs, a two-week pilot was initiated in partnership with five public health hospitals without any previous existing telehealth structure. The volunteers completed 109 PC consults in the pilot period. Survey feedback from TPMVs and on-site PC providers was largely positive, with areas of improvement identified around electronic health record navigation and continuity of care. https://www.selleckchem.com/products/fti-277-hcl.html This was a successful, proof of concept, and quality improvement initiative leveraging TPMVs from across the nation for a PC pandemic response in a safety net system.

Furthermore, multiple functionalization of carbazole moieties reveals that polycyclic aromatic systems employed as acceptor units of host materials are best suited for PhOLEDs as they will increase their lifetime due to the larger ΔGS1-TS* and ΔES1-T1. For TADF-based devices, materials with fused ring systems (with N(sp3) at the centre) in the donor unit are the most recommended ones based on the findings of this work, as they avoid the dissociative channel altogether. A negative linear correlation between ΔGS1-TS* and HOMO-LUMO gap is observed, which provides an indirect way to predict the kinetic stability of these materials in excitonic states. These initial results are promising for the future development of the QSAR-type approach for the smart design of host materials for long-life blue OLEDs.Over the last decade, much work has been dedicated to improving the performance of gadolinium-based magnetic resonance imaging (MRI) contrast agents by tethering them to biocompatible gold nanoparticles. The enhancement in performance (measured in terms of 'relaxivity') stems from the restriction in motion experienced by the gadolinium chelates on being attached to the gold nanoparticle surface. More recently, the unique properties of gold nanoparticles have been exploited to create very promising tools for multimodal imaging and MRI-guided therapies. This review addresses the progress made in the design of gadolinium-functionalised gold nanoparticles for use in MRI, multimodal imaging and theranostics. It also seeks to connect the chemical properties of these assemblies with potential application in the clinic.Detection of chemical reactions in living cells is critical in understanding physiological metabolic processes in the context of nanomedicine. Carbon monoxide (CO) is one of the important gaseous signaling molecules. Surface-enhanced Raman spectroscopy (SERS)-based CO-releasing nanoparticles (CORN) is utilized to investigate the chemical reaction of CO delivery in live cells. Using SERS CORN, carbonyl dissociation from CORN-Ag-CpW(CO)3 to CORN-Ag-CpW(CO)2 in live cells is observed. The subsequent irreversible degradation to CO-free CORN is a consequence of oxidative stress in cells. This observation affirms the step transition of CORN-Ag-CpW(CO)3 in cellular CORN-Ag-CpW(CO)3 first proceeds via a direct loss of one CO followed by a oxidative decomposition giving rise to CORN-Ag-WO3 and as well as the release of one equivalents of CO. https://www.selleckchem.com/products/sd49-7.html Importantly, the decarbonylation process can be correlated with the level of inflammatory biomarkers. For the first time, we provide unambiguous evidence for the steps transition of CO-release mechanism in cellular.CO is extremely toxic to humans since it can combine with haemoglobin to form carboxy-haemoglobin that reduces the oxygen-carrying capacity of blood. Metal-organic frameworks (MOFs), in particular InOF-1, are currently receiving preferential attention for the separation and capture of CO. In this investigation we report a theoretical study based on periodic density-functional-theory (DFT) analysis and matching experimental results (in situ DRIFTS). The aim of this article is to describe the non-covalent interactions between the functional groups of InOF-1 and the CO molecule since they are crucial to understand the adsorption mechanism of these materials. Our results show that the CO molecule mainly interacts with the μ2-OH hydroxo groups of InOF-1 through O-HO hydrogen bonds, and Cπ interactions by the biphenyl rings of the MOF. These results provide useful information on the CO adsorption mechanisms in InOF-1.The primary processes that occur following direct irradiation of bio-macromolecules by ionizing radiation determine the multiscale responses that lead to biomolecular lesions. The so-called physical stage loosely describes processes of energy deposition and molecular ionization/excitation but remains largely elusive. We propose a new approach based on first principles density functional theory to simulate energy deposition in large and heterogeneous biomolecules by high-energy-transfer particles. Unlike traditional Monte Carlo approaches, our methodology does not rely on pre-parametrized sets of cross-sections, but captures excitation, ionization and low energy electron emission at the heart of complex biostructures. It furthermore gives access to valuable insights on ultrafast charge and hole dynamics on the femtosecond time scale. With this new tool, we reveal the mechanisms of ionization by swift ions in microscopic DNA models and solvated DNA comprising almost 750 atoms treated at the DFT level of description. We reveal a so-called ebb-and-flow ionization mechanism in which polarization of the irradiated moieties appears as a key feature. We also investigate where secondary electrons produced by irradiation localize on chemical moieties composing DNA. We compare irradiation of solvated DNA by light (H+, and He2+) vs. heavier (C6+) ions, highlighting the much higher probability of double ionization with the latter. Our methodology constitutes a stepping stone towards a greater understanding of the chemical stage and more generally towards the multiscale modelling of radiation damage in biology using first principles.Transformation of metastable supramolecular stacks of hydrogen-bonded rosettes composed of an ester-containing barbiturated naphthalene into crystalline nanosheets occurs through the rearrangement of hydrogen-bonding patterns. The involvement of the ester group in the crystalline hydrogen-bonded pattern is demonstrated, guiding us to a new molecular design that can afford supramolecular polymorphs with soft and hard molecular packing.Phase transition occurring during cycling plays a fundamentally important role in the cycling performance of nickel-rich cathodes. Here, splitting of two O3 phases, rather than the often observed O1 phases in the conventional LiCoO2 electrode, was discovered in LiNi0.85Co0.10Mn0.05O2 at a high-voltage region (>4.6 V). Such degradation could be mitigated via Al doping.Organic-inorganic halide hybrids are rapidly gaining increased attention owing to their remarkable optoelectronic performance. Amongst these, divalent and trivalent metal cations (Pb2+, Sn2+, Bi3+, and Sb3+) usually link to six halogen X atoms and form an asymmetric [MX6] octahedron with weak optical anisotropy. Herein, we show a first family of monovalent-metal-based hybrid halides [N(CH3)4]MCl2 (M = Ga, In) with a zero-dimensional configuration containing unprecedented linear [MX2] units. Owing to the reduced coordination number, the lone pairs on Ga+ and In+ exhibit quasi-two-dimensional distribution, thereby leading to a narrowed bandgap, enhanced optical anisotropy and strong nonlinear second harmonic response of 1.4 and 1.3 times that of benchmark KH2PO4, respectively.

1%). The mean ratings of performance varied from 3.7 to 8.4. The lowest mean rating was in the subgroup play/school (3.7). For satisfaction, the mean ratings were from 2.6 to 5.2, with functional mobility as the highest and play/school the lowest. The results support the use of the COPM in clinical practice for children with cancer. Based on these findings, children with cancer perceive problems with occupations related to all aspects of daily life. This underlines the need to provide rehabilitation services, especially occupational therapy services for these children.Introduction The methods employed to document cystoscopic findings in bladder cancer patients lack accuracy and are subject to observer variability. We propose a novel endoimaging system and an online documentation platform to provide post-procedural 3D bladder reconstructions for improved diagnosis, management and follow-up.Material and methods The RaVeNNA4pi consortium is comprised of five industrial partners, two university hospitals and two technical institutes. These are grouped into hardware, software and clinical partners according to their professional expertise. The envisaged endoimaging system consists of an innovative cystoscope that generates 3D bladder reconstructions allowing users to remotely access a cloud-based centralized database to visualize individualized 3D bladder models from previous cystoscopies archived in DICOM format.Results Preliminary investigations successfully tracked the endoscope's rotational and translational movements. The structure-from-motion pipeline was tested in a bladder phantom and satisfactorily demonstrated 3D reconstructions of the processing sequence. AI-based semantic image segmentation achieved a 0.67 dice-score-coefficient over all classes. An online-platform allows physicians and patients to digitally visualize endoscopic findings by navigating a 3D bladder model.Conclusions Our work demonstrates the current developments of a novel endoimaging system equipped with the potential to generate 3D bladder reconstructions from cystoscopy videos and AI-assisted automated detection of bladder tumors.Cabozantinib is an oral tyrosine kinase inhibitor that targets VEGFR, MET and the TAM (TYRO3, AXL, MER) family of kinase receptors. In addition to their role in tumor growth and angiogenesis, cabozantinib targets promote an immune-suppressive microenvironment. Cabozantinib is approved as single-agent therapy for patients with advanced hepatocellular carcinoma who received prior sorafenib. Owing to its antitumor and immunomodulatory properties, cabozantinib is being developed in combination with immune checkpoint inhibitors. Early studies of these combinations have shown promising antitumor activity and tolerability in patients with solid tumors. Here, we describe the rationale and design of COSMIC-312, a Phase III study evaluating the safety and efficacy of cabozantinib in combination with atezolizumab (anti-PD-L1 monoclonal antibody) versus sorafenib for treatment-naive patients with advanced hepatocellular carcinoma. Clinical Trial Registration NCT03755791 (ClinicalTrials.gov).Objectives To investigate the assessment of inflammatory jaw pathologies using bone single-photon emission CT-CT (SPECT/CT) maximum standardized uptake value (SUVmax). Methods 44 patients with inflammatory jaw pathologies (7 chronic osteomyelitis, 8 osteoradionecrosis and 29 medication-related osteonecrosis of the jaw (MRONJ)) underwent SPECT/CT at 4 h after injection of 99mTc hydroxymethylene diphosphonate. The SPECT/CT parameters SUVmax of the inflammatory jaw pathologies were analyzed. Statistical analyses for the SUVmax were performed by one-way repeated measures analysis of variance with Tukey's honestly significant difference test. https://www.selleckchem.com/products/pacritinib-sb1518.html A p-value lower than 0.05 was considered statistically significant. Results The mean and standard deviation of SUVmax for 7 chronic osteomyelitis, 8 osteoradionecrosis and 29 MRONJ were 24.94 ± 3.65, 12.27 ± 5.47 and 16.55 ± 9.12, respectively. The SUVmax for chronic osteomyelitis were significantly higher than those for osteoradionecrosis (p = 0.011) and MRONJ (p = 0.043). Conclusions Bone SPECT/CT SUVmax in the uptake of 99mTc hydroxymethylene diphosphonate reflecting bone physiological changes for chronic osteomyelitis were significantly higher than those of osteonecrosis, such as osteoradionecrosis and MRONJ. Bone SPECT/CT SUVmax should be useful for the assessment of inflammatory jaw pathologies, such as chronic osteomyelitis, osteoradionecrosis and MRONJ.Introduction Rehearsing endovascular aortic aneurysm repair on patient-specific data is recent within virtual reality simulation and opens up new possibilities for operators to prepare for complex procedures. This study evaluated the feasibility of patient-specific rehearsal (PsR) and assessed operators' appraisal of the VIST-LAB simulator from Mentice.Material and methods CT-data was segmented and uploaded to the simulator, and simulated for 30 elective EVAR patients. Operators were asked how they perceived the PsR on a Likert scale after the PsR (once) and after the following procedure (each time).Results Patients were simulated and operated by 14 operators, always in pairs of one vascular surgeon and one interventional radiologist. The operators estimated that PsR improved individual and team performance (median 4), and recommended the use of PsR in general (median 4) and for difficult cases (median 5). The simulator realism got moderate scores (median 2-3). Inexperienced operators seemed to appreciate the PsR the most.Conclusions PsR was feasible and was evaluated by operators to improve individual and team performance. Inexperienced users were more positive towards PsR than experienced users. PsR realism and the ease of importing patient-specific data can still be improved, and further studies to quantify and precisely identify benefits are needed.Hysterectomy remains one of the most commonly performed gynecological procedures. The distinction between total and subtotal (supracervical) hysterectomy has many facets. Based on anatomical structures, a distinction is made between total and subtotal hysterectomy. In the present report, various factors affecting therapy decisions are examined individually and viewed in the context of the existing published literature. The surgical steps of total laparoscopic hysterectomy (TLH) and laparoscopic supracervical hysterectomy (LASH) are described didactically. Medical-ethical aspects of the increasingly complex balance between the scarcity of resources on the one hand, and growing demands on the other, form the basis of our medical decisions.
