Hand Hygiene Knowledge and Hand Dirtiness Assessment to Inform Alcohol-Based Hand Rub Appropriateness in Community Settings in Uganda and Kenya.

During the coronavirus disease 2019 pandemic, alcohol-based hand rub (ABHR) availability and use increased as a prevention measure. ABHR is a convenient, effective way to kill microbes on hands but is hampered by the presence of organic material, whereas handwashing with water and soap (HWWS) can physically remove microbes and dirt. Although ABHR is preferred in most health care settings, the suitability of ABHR use in community settings has not been measured.

Factors associated with hand hygiene adherence among healthcare workers in Guatemala during the COVID-19 pandemic.

Background: Healthcare-associated infections are prevalent in low- and middle-income countries and may be reduced through proper hand hygiene (HH) adherence during patient care.

Aim: We produced and distributed alcohol-based hand rub (ABHR) to 19 public primary- and secondary-level healthcare facilities in Quetzaltenango, Guatemala, and carried out HH observations to assess healthcare workers' (HCWs) HH adherence, and to identify factors associated with this practice. HH adherence was defined as washing hands with soap and water or using ABHR.

Hand hygiene perceptions, preferences, and practices among hospital staff in the Dominican Republic in the context of COVID-19: a qualitative study.

Background: Proper hand hygiene (HH), which includes sanitizing with alcohol-based hand rub (ABHR) (or handwashing with soap and water if ABHR is unavailable), is key for preventing healthcare-associated infections (HCAI), including COVID-19. Understanding drivers of HH is key to improving adherence.

Aim: This study aims to explore drivers and barriers to HH practice at two hospitals in the Dominican Republic in the context of the COVID-19 pandemic to inform development of HH behaviour change interventions.

Water, Sanitation, and Hygiene Infrastructure and Resources in Schools in Belize during the COVID-19 Pandemic, 2021-2023.

Access to water, sanitation, and hygiene (WASH) resources in schools is critical for disease prevention and control, especially during public health emergencies. In Belize, systematic, national data on WASH in schools are needed to inform public health decisions and interventions. From December 2021 to January 2022, a national survey was sent electronically to government and government-aided primary and secondary schools in Belize (N = 308) to gather information on WASH services.

Assessing hand hygiene knowledge, attitudes, and behaviors among Guatemalan primary school students in the context of the COVID-19 pandemic.

Background: Hand hygiene (HH) is an important practice that prevents transmission of infectious diseases, such as COVID-19. However, in resource-limited areas, where water and soap are not always available, it can be difficult to practice HH correctly and at appropriate moments. The purpose of this study was to assess HH knowledge and behaviors among students from six elementary schools in Quetzaltenango, Guatemala to identify gaps that could later inform interventions to improve HH.

Assessment of Water, Sanitation, and Hygiene Conditions in Public Elementary Schools in Quetzaltenango, Guatemala, in the Context of the COVID-19 Pandemic.

Water, sanitation, and hygiene (WASH) services in schools are essential to reduce infectious disease transmission, including that of COVID-19. This study aimed to establish a baseline of WASH services in six public elementary schools in Guatemala, with a focus on hand hygiene. We used the WHO/UNICEF Joint Monitoring Programme (JMP) report indicators to assess the WASH infrastructure at each school.

Overturning in the subpolar North Atlantic: a review.

The Overturning in the Subpolar North Atlantic Program (OSNAP) was initiated in the spring of 2010 through a collaborative effort involving the USA, the UK, Germany, the Netherlands and Canada. A key feature of OSNAP is a trans-basin observing system deployed in the summer of 2014 for the continuous measure of volume, heat and freshwater fluxes in the subpolar North Atlantic. This review focuses on advancements made possible by the collective OSNAP observations.

Buoyancy forcing and the subpolar Atlantic meridional overturning circulation.

The North Atlantic meridional overturning circulation and its variability are examined in terms of the overturning in density space and diapycnal water mass transformation. The magnitude of the mean overturning is similar to the surface water mass transformation, but the density and properties of these waters are modified by diapycnal mixing. Surface waters are progressively densified while circulating cyclonically around the subpolar gyre, with the densest waters and deepest convection occurring in the Labrador Sea and Nordic Seas.

Access to and Use of Hand Hygiene Resources during the COVID-19 Pandemic in Two Districts in Uganda, January-April 2021.

To understand access to and use of hand hygiene in healthcare facilities (HCFs) and community locations during the COVID-19 pandemic, we evaluated factors associated with hand hygiene in 60 priority HCFs and community locations in two border districts in Uganda. We assessed water and hand hygiene resource availability and observed hand hygiene practice by staff or patrons. Regression modeling estimated factors associated with the availability or use of hand hygiene.

Identification of risk factors and mosquito vectors associated with dengue virus infection in American Samoa, 2017.

Introduction: The first outbreak of dengue in American Samoa was reported in 1911. Sporadic outbreaks have been reported since, as were outbreaks of other pathogens transmitted by Aedes species mosquitoes including Ross River, chikungunya, and Zika viruses. During an outbreak of dengue virus-type 2 (DENV-2) in 2016-2018, we conducted household-based cluster investigations to identify population-specific risk factors associated with infection and performed entomologic surveillance to determine the relative abundance of Ae.

Seasonality of the Meridional Overturning Circulation in the subpolar North Atlantic.

Understanding the variability of the Atlantic Meridional Overturning Circulation is essential for better predictions of our changing climate. Here we present an updated time series (August 2014 to June 2020) from the Overturning in the Subpolar North Atlantic Program. The 6-year time series allows us to observe the seasonality of the subpolar overturning and meridional heat and freshwater transports.

Improving Access to WHO Formulations of Alcohol-Based Hand Rub in Healthcare Facilities: A District-Wide Approach.

Alcohol-based hand rub (ABHR) is an effective hand hygiene measure to mitigate and prevent infectious disease transmission in healthcare facilities (HCFs); however, availability and affordability in low- and middle-income countries are limited. We sought to establish centralized local production of ABHR using a district-wide approach to increase provider access at all public HCFs in Kabarole and Kasese Districts in Western Uganda. Partner organizations worked with district governments to adapt and implement the WHO protocol for local ABHR production at the district scale.

Cholera Outbreak - Haiti, September 2022-January 2023.

On September 30, 2022, after >3 years with no confirmed cholera cases (1), the Directorate of Epidemiology, Laboratories and Research (DELR) of the Haitian Ministry of Public Health and Population (Ministère de la Santé Publique et de la Population [MSPP]) was notified of two patients with acute, watery diarrhea in the metropolitan area of Port-au-Prince. Within 2 days, Haiti's National Public Health Laboratory confirmed the bacterium Vibrio cholerae O1 in specimens from the two patients with suspected cholera infection, and an outbreak investigation began immediately. As of January 3, 2023, >20,000 suspected cholera cases had been reported throughout the country, and 79% of patients have been hospitalized.

A 51-year-old female with Raynaud's phenomenon who was started on phentermine one week prior presented with a one-day history of palpitations.

Establishment of District-Led Production of WHO-Recommended Alcohol-based Hand Rub (ABHR) during the COVID-19 Pandemic: A Model for Improving Access to ABHR during Health Emergencies.

In response to the COVID-19 pandemic, we established and sustained local production of alcohol-based handrub (ABHR) at district scale for healthcare facilities and community, public locations in four districts in Uganda. District officials provided space and staff for production units. The project renovated space for production, trained staff on ABHR production, and transported ABHR to key locations.

In-Hospital Outcomes of Transcatheter Tricuspid Valve Repair: An Analysis From the National Inpatient Sample.

Background: Patients with severe tricuspid regurgitation carry an elevated surgical risk resulting in increasing adoption of less invasive transcatheter therapies such as transcatheter tricuspid valve repair (TTVR); however, data are limited. This study aimed to describe patient characteristics and predictors of poor outcomes among those undergoing TTVR.

Methods: The National Inpatient Sample was queried (2016-2019) to identify all patients undergoing TTVR ( code 02UJ3JZ) alone or in combination with mitral transcatheter edge-to-edge repair (MTEER) (code 02UG3JZ).

Passive In-Line Chlorination for Drinking Water Disinfection: A Critical Review.

The world is not on track to meet Sustainable Development Goal 6.1 to provide universal access to safely managed drinking water by 2030. Removal of priority microbial contaminants by disinfection is one aspect of ensuring water is safely managed.

When "Blue Babies" Grow Up: Complications After Surgical Repair of Tetralogy of Fallot.

Tetralogy of Fallot (TOF) is a complex congenital cardiac defect. Surgical correction is well established as the treatment of choice and has resulted in a rapidly growing group of adults living with TOF. We describe potential complications of patients who have undergone TOF repair and were lost to follow-up.

A systematic review on the use of ultrasound enhancing agents with transesophageal echocardiography to assess the left atrial appendage prior to cardioversion.

Background: Assessment of the left atrium and atrial appendage (LAA) for thrombus by transesophageal echocardiography (TEE) may be suboptimal due to difficult imaging windows and ultrasound artifacts. The present study analyzed the benefit of using ultrasound enhancing agents (UEAs) with TEE to improve diagnostic accuracy and image quality.

Methods: A systematic review of studies published through December 2020 was performed, and included investigations comparing the number of cases deemed indeterminate for visualization of LAA thrombi on TEE pre- versus post-UEAs prior to cardioversion for atrial fibrillation or flutter (AF).

Subpolar North Atlantic western boundary density anomalies and the Meridional Overturning Circulation.

Changes in the Atlantic Meridional Overturning Circulation, which have the potential to drive societally-important climate impacts, have traditionally been linked to the strength of deep water formation in the subpolar North Atlantic. Yet there is neither clear observational evidence nor agreement among models about how changes in deep water formation influence overturning. Here, we use data from a trans-basin mooring array (OSNAP-Overturning in the Subpolar North Atlantic Program) to show that winter convection during 2014-2018 in the interior basin had minimal impact on density changes in the deep western boundary currents in the subpolar basins.

The Harder the Heart, the Harder It Breaks: A Case of Complete Atrioventricular Block Secondary to Tertiary Hyperparathyroidism.

The appearance of first-degree atrioventricular block and mitral annulus calcification in an end-stage renal failure patient with elevated parathyroid hormone levels should raise the suspicion of metastatic cardiac calcification. Measures should be taken to normalize the parathyroid hormone, calcium, and phosphorus levels to limit the progression of atrioventricular block. Exploration or removal of parathyroid glands should be considered if heart block worsens.
