[CORONA VIRUS, BREASTFEEDING AND GUIDELINES - A WORLDWIDE REVIEW].

INTRODUCTION: The COVID-19 pandemic has forced countries worldwide to face major issues and challenges. Among those challenges is breastfeeding from the first hours after birth until late infancy, in hospitals and communities. There is a consensus throughout the world and among leading international professional medical associations that breastfeeding is of significant importance for short- and long-term health outcomes in mothers and infants, as well as for its public health impact and reduction of national health expenditures. Moreover, breastfeeding or human milk feeding have been shown to reduce morbidity, specifically respiratory infections, among infants and children. This is not the first time health systems are dealing with coronavirus outbreaks, although currently, in the COVID-19 pandemic, there is still much that is unknown. Dealing with the unknown can lead to guidelines that may not fully take into consideration relevant risk benefit ratios for individuals and groups. In this review, we aim to summarize the guidelines of different leading professional groups around the world dealing with the COVID-19 pandemic. Evidence-based medicine rests on relevant scientific evidence, patients' values and preferences and clinical judgment. We wish to propose guidelines based on available evidence concerning breastfeeding, the current pandemic and weighing in potential risks and benefits while highlighting the need for ongoing breastfeeding research.

Risk assessment of human mpox infections: retrospective cohort study.

OBJECTIVES: The global supply of vaccines against mpox (previously called monkeypox virus infection) was significantly lower than the demand. Therefore, evidence-based vaccine prioritization criteria, based on risk assessment were needed. Our objective was therefore to identify the characteristics of individuals at the highest risk for mpox. METHODS: This population-based cohort study included all Clalit Health Services (CHS) subjects assumed to be at risk for mpox. The eligibility criteria for inclusion were determined based on known characteristics of people with infection worldwide and insights of lesbian, gay, bisexual, transgender, queer+ (LGBTQ+) -specialized CHS clinicians. Cox hazards models were used to identify the risk factors for mpox within the study cohort. The study commenced on 6 June 2022, the date of the first known mpox in CHS members, until 31 July 2022, when the mpox vaccination campaign started. RESULTS: A total of 8088 individuals of 4.7 million CHS members (0.18%) were identified according to the study inclusion criteria. Of those, 69 (0.85%) developed infection during the study period. Risk factors for mpox were birth in 1980 or later (hazard ratio, 5.04; 95% CI, 2.11-12.02), history of syphilis (2.62; 1.58-4.35), registration to primary healthcare clinics in the Tel Aviv district (2.82; 1.44-5.54), HIV-pre-exposure prophylaxis medication use (3.96; 2.14-7.31), PDE5 inhibitors use (2.92; 1.77-4.84), and recent sexually transmitted infections (STIs) within the last 18 months (2.27; 1.35-3.82). No infections were observed in individuals with none of the factors. Individuals with three or more risk factors had a 20.30-fold (10.39-39.69) higher risk for mpox compared with those with 0-2, with 85.5% (75.0-92.8%) sensitivity and 77.8% (76.9-78.7%) specificity. DISCUSSION: Weighting individuals' risk levels based on validated risk factors against vaccine availability can assist health systems in the equitable prioritization of vaccine allocation in various future outbreaks, given supply-demand gaps.

Sex difference in the association between malnutrition and hypoglycemia in hospitalized patients.

BACKGROUND: The aim of this paper was to examine the difference between males and females regarding association between malnutrition risk and hypoglycemia through a sub-analysis of a cross-sectional study of newly admitted patients to internal medicine departments. METHODS: Malnutrition risk, assessed with Nutritional Risk Screening 2002 (NRS2002), and serum albumin were measured upon admission. Logistic regression was applied to men and women separately, to test the effect of malnutrition and hypoalbuminemia on incidence of hypoglycemia. RESULTS: Included were 1186 patients (50.4% males, 39.2% with positive NRS2002). Rate of positive NRS2002 was similar across sexes (36.5% vs. 41.2% in males and females respectively, P=0.204). Among females, NRS2002 was associated with higher incidence of hypoglycemia (9.5% vs. 2.4% in NRS2002 negative females, P<0.001). Among males, no such difference was noted (9.2% compared to 7.1% in NRS2002 positive and negative males respectively, P=0.520). The weight loss/decreased food intake criterion of the NRS2002 was significantly higher in the hypoglycemic group within females (P=0.03). Logistic regression showed that serum albumin was inversely associated with hypoglycemia in both females (OR 0.477, 95% CI 0.282-0.806, P=0.006) and males (OR 0.532, 95% CI 0.355-0.795, P=0.002). However, increased malnutrition risk was associated with hypoglycemia only among females (OR 2.007, 95% CI 1.058-3.809, P=0.033). Diabetes status was associated with hypoglycemia (OR 1.907, 95% CI 1.056-3.445, P=0.032) only in males; this association did not occur in females. CONCLUSIONS: Malnutrition risk, as measured by the NRS2002, is associated with significantly increased incidence of hypoglycemia in women alone. Females who lose weight prior to hospitalization have an increased risk to develop hypoglycemia.
