Comparing cancer and cardiovascular disease trends in 20 middle- or high-income countries 2000-19: A pointer to national trajectories towards achieving Sustainable Development goal target 3.4.

Cancer Treat Rev 2021 Sep 9;100:102290. Epub 2021 Sep 9.

Cancer Surveillance Branch, International Agency for Research on Cancer, Lyon, France.

With the 2030 Sustainable Development Goals (SDG) target of a one-third reduction in noncommunicable diseases (NCDs) less than a decade away, it is timely to assess national progress in reducing premature deaths from the two leading causes of mortality worldwide. We examine trends in the probability of dying ages 30-70 from cardiovascular disease (CVD) and cancer 2000-19 in 10 middle-income (MICs) and 10 high-income (HICs) countries with high quality data. We then predict whether the SDG target will be met in each country for CVD, cancer and for the four main NCDs combined. Read More

Basal cortisol concentrations related to maternal behavior during puppy development predict post-growth resilience in dogs.

Horm Behav 2021 Sep 15;136:105055. Epub 2021 Sep 15.

Department of Animal Science and Biotechnology Azabu University, 1-17-71 Fuchinobe, Chuo-ku, Sagamihara 252-5201, Kanagawa, Japan. Electronic address:

A prolonged stress hyporesponsive period (SHRP) due to the mother's presence may delay the timing of glucocorticoid (GC) elevation in infants, thereby reducing the excessive stress response that would affect post-growth temperament. In dogs, the SHRP has been suggested to persist until postnatal week (PW) 4; therefore, PW 5, which SHRP may be prolonged by the mother dog, may be a critical point in the developmental stage of dogs to establish stress responsiveness. We conducted a long-term survey on the development of dogs to investigate i) whether the degree of the stress response at PW 5 is determined by maternal behavior and ii) whether it can predict post-growth stress responses and temperament in dogs.

The fairness of ventilator allocation during the COVID-19 pandemic.

Authors:
Xueshi Wang

Bioethics 2021 Sep 18. Epub 2021 Sep 18.

Department of Philosophy, Harvard University, Cambridge, Massachusetts, USA.

There is ongoing debate on how to fairly allocate scarce critical care resources to patients with COVID-19. The debate revolves around two views: those who believe that priority for scarce resources should primarily aim at saving the most lives (SML) or at saving the most life-years, and those who believe that public health should focus on health equity to address health disparities and social determinants of health. I argue that maximizing medical outcomes by saving the greatest number of patients is not a plausible strategy for combating COVID-19. Read More

The management of moderate acute malnutrition in children aged 6-59 mo in low- and middle-income countries: a systematic review and meta-analysis.

Trans R Soc Trop Med Hyg 2021 Sep 17. Epub 2021 Sep 17.

Department of Medical Statistics, London School of Hygiene and Tropical Medicine, London, WC1E 7HT, UK.

Background: Malnutrition is a leading cause of morbidity and mortality in children aged <5 y, especially in low- and middle-income countries (LMICs). Unlike severe acute malnutrition, moderate acute malnutrition (MAM) affects greater numbers globally, and guidelines lack a robust evidence base. This systematic review and meta-analysis assessed the evidence for lipid-based nutrient supplements (LNSs), fortified blended flours (FBFs) and nutrition counselling, in the treatment of MAM.

Overall Survival of Patients Receiving Cisplatin or Carboplatin for Primary Metastatic Urothelial Carcinoma of the Bladder: A Contemporary Dutch Nationwide Cohort Study.

Eur Urol Focus 2021 Sep 14. Epub 2021 Sep 14.

Department of Research and Development, The Netherlands Comprehensive Cancer Organisation, Utrecht, The Netherlands; Radboud Institute for Health Sciences, Radboud University Medical Center, Nijmegen, The Netherlands.

Background: Cisplatin is preferred to carboplatin when treating metastatic urothelial carcinoma of the bladder (mUCB), despite its greater toxicity. Randomised studies underpinning this have been performed in noncontemporary populations with limitations in sample sizes and analyses, affecting their validity in current clinical practice.

Front Med (Lausanne) 2021 31;8:726950. Epub 2021 Aug 31.

Department of Infectious Diseases, Institute of Infection and Immunology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Patients with cirrhosis have an increased risk of short-term mortality, however, few studies quantify the association between neutrophil-to-lymphocyte ratio (NLR) and 90-day transplant-free mortality in cirrhotic patients. We prospectively analyzed 3,970 patients with chronic liver diseases from two multicenter cohorts in China (January 2015 to December 2016 and July 2018 to January 2019). Restricted cubic splines (RCS) were used to analyze the relation of NLR and all-causes 90-day transplant-free mortality in cirrhosis. Read More

High turn-over rates at the upper range limit and elevational source-sink dynamics in a widespread songbird.

Sci Rep 2021 Sep 16;11(1):18470. Epub 2021 Sep 16.

Swiss Ornithological Institute, Seerose 1, 6204, Sempach, Switzerland.

The formation of an upper distributional range limit for species breeding along mountain slopes is often based on environmental gradients resulting in changing demographic rates towards high elevations. However, we still lack an empirical understanding of how the interplay of demographic parameters forms the upper range limit in highly mobile species. Here, we study apparent survival and within-study area dispersal over a 700 m elevational gradient in barn swallows (Hirundo rustica) by using 15 years of capture-mark-recapture data. Read More

Department of Urology, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University, 107 West Yanjiang Road, Guangzhou, 510210, China.

Background: Balloon dilation is a commonly used minimally invasive endourological treatment of ureteral stricture, but the postoperative recurrence rate is relatively high. And factors contributing to recurrence after treatment are poorly understood. Herein, we sought to develop a novel clinical nomogram to predict ureteral stricture-free survival in patients suffering from ureter stricture and performed balloon dilation. Read More

ASXL1 and STAG2 are Common Mutations in GATA2 Deficiency Patients with Bone Marrow Disease and Myelodysplastic Syndrome.

Blood Adv 2021 Sep 16. Epub 2021 Sep 16.

National Insitutes of Health, Bethesda, Maryland, United States.

GATA2 Deficiency patients harbor de novo or inherited germline mutations in the GATA2 transcription factor gene, predisposing them to myeloid malignancies. There is considerable variation in disease progression, even among family members with the same mutation in GATA2. We investigated somatic mutations in 106 patients with GATA2 Deficiency to identify acquired mutations that are associated with myeloid malignancies. Read More

Models Predicting Hospital Admission of Adult Patients Utilizing Prehospital Data: Systematic Review Using PROBAST and CHARMS.

JMIR Med Inform 2021 Sep 16;9(9):e30022. Epub 2021 Sep 16.

Department of Health Services Administration, University of Alabama at Birmingham, Birmingham, AL, United States.

Background: Emergency department boarding and hospital exit block are primary causes of emergency department crowding and have been conclusively associated with poor patient outcomes and major threats to patient safety. Boarding occurs when a patient is delayed or blocked from transitioning out of the emergency department because of dysfunctional transition or bed assignment processes. Predictive models for estimating the probability of an occurrence of this type could be useful in reducing or preventing emergency department boarding and hospital exit block, to reduce emergency department crowding.
