Introduction: The 2022 Mpox outbreak is the largest viral outbreak recorded outside of Africa. The recent rise in human outbreaks has led to the perception that Mpox, an emerging zoonotic disease, has potential for epidemic spread. Healthcare practitioners are familiarizing themselves with the varied clinical manifestations and therapeutic approaches for this virus while public health organizations seek to limit the outbreak and treat those affected.

The relationship between gut microbiota, short chain fatty acid (SCFA) metabolism, and obesity is still not well understood. Here we investigated these associations in a large (n=1904) African origin cohort from Ghana, South Africa, Jamaica, Seychelles, and the US. Fecal microbiota diversity and SCFA concentration were greatest in Ghanaians, and lowest in the US population, representing the lowest and highest end of the epidemiologic transition spectrum, respectively.

This article provides a stocktake of the adaptation literature between 2013 and 2019 to better understand how adaptation responses affect risk under the particularly challenging conditions of compound climate events. Across 39 countries, 45 response types to compound hazards display anticipatory (9%), reactive (33%), and maladaptive (41%) characteristics, as well as hard (18%) and soft (68%) limits to adaptation. Low income, food insecurity, and access to institutional resources and finance are the most prominent of 23 vulnerabilities observed to negatively affect responses.

Tracking health system performance in times of crisis using routine health data: lessons learned from a multicountry consortium.

Health Res Policy Syst

January 2023

Department of Global Health and Population, Harvard T.H. Chan School of Public Health, 401 Park Drive, 3Rd Floor East, room L3-015A5, Landmark Center, Boston, MA, 02215, USA.

COVID-19 has prompted the use of readily available administrative data to track health system performance in times of crisis and to monitor disruptions in essential healthcare services. In this commentary we describe our experience working with these data and lessons learned across countries. Since April 2020, the Quality Evidence for Health System Transformation (QuEST) network has used administrative data and routine health information systems (RHIS) to assess health system performance during COVID-19 in Chile, Ethiopia, Ghana, Haiti, Lao People's Democratic Republic, Mexico, Nepal, South Africa, Republic of Korea and Thailand.

Relationship between vertical jump tests and ice skating performance in junior Polish ice hockey players.

Biol Sport

January 2023

Institute of Sport Sciences, Department of Exercise and Sport Performance, Jerzy Kukuczka Academy of Physical Education, Mikołowska 72A, 40-065 Katowice, Poland.

The aim of this study was to determine the relationships between vertical jumps (VJ) and various on-ice skating performances of junior ice hockey players (n = 19). The three modes of VJ or off-ice measures were countermovement jump with arm swing (CMJ), squat jump (SJ) and depth drop jump (DDJ). The on-ice skating performance was measured by the skating multistage aerobic test (SMAT), forward and backward acceleration test, top speed test, and repeated sprint ability (RSA) test.

The purpose of this study was to evaluate the effects of two different rest intervals (2 min and 3 min), between two consecutive sets of repeated sprint skating ability (RSSA) tests, on the repeated sprint ability of ice hockey Forwards and Defensemen. Two protocols of RSSA tests, RSSA-2 and RSSA-3, were completed by 16 ice hockey Forwards and 8 Defensemen. Defensemen were heavier (p < 0.

Impact of Smoking on Functional Prognosis after Ischemic Stroke according to Deprivation: A Prospective Cohort Study.

Neuroepidemiology

February 2023

Dijon Stroke Registry, EA7460, Pathophysiology and Epidemiology of Cerebro-Cardiovascular diseases (PEC2), University Hospital of Dijon, University of Burgundy, Dijon, France.

Background: Smoking influence on poststroke prognosis remains controversial. These conflicting results could be due to some residual confounding factors not fully considered in previous studies, including social deprivation. This study aimed to assess the joint impact of deprivation and smoking on functional outcomes after ischemic stroke.

Background: Diagnosis of acute rheumatic fever (ARF) is mainly clinical. Delayed or missed diagnosis and failure to administer appropriate and timely treatment of ARF leads to rheumatic heart disease (RHD), which could necessitate expensive treatments such as open-heart surgery. Implementation of preventative guidelines depends on availability of trained healthcare workers.

The present study was conducted in the Piparo mud-volcano, which is situated in the central part of the island of Trinidad, is geologically connected with the Central Fault Range Zone (CFRZ). This fault zone is a neotectonic (active) strike-slip fault system and an extension of the Andes Mountain chain. This study was aimed at detecting the possible gamma radiation level in Piparo MV after its eruption in September 2019 and finding the change in the ambient radiation level after that eruption.

Article Synopsis
  • - The study analyzed 60 Listeria monocytogenes isolates from various sources in Gauteng, South Africa, using multiple-locus variable-number analysis (MLVA) to determine their genotypes and serogroups.
  • - The sources included raw beef, ready-to-eat products, carcass swabs, cattle environments, and feces, with findings showing significant distribution across these sample types.
  • - MLVA successfully identified genetic relations and differences among the isolates, revealing distinct patterns in tandem repeats (TRs) and leading to the identification of at least five MLVA types in the region.

Declines in health service use during the Coronavirus Disease 2019 (COVID-19) pandemic could have important effects on population health. In this study, we used an interrupted time series design to assess the immediate effect of the pandemic on 31 health services in two low-income (Ethiopia and Haiti), six middle-income (Ghana, Lao People's Democratic Republic, Mexico, Nepal, South Africa and Thailand) and high-income (Chile and South Korea) countries. Despite efforts to maintain health services, disruptions of varying magnitude and duration were found in every country, with no clear patterns by country income group or pandemic intensity.

The impact of two different passive recovery durations, two and three minutes, between sets of repeated sprint skating ability (RSSA) test on skating speed, speed decrement (S), and heart rate (HR) response of ice hockey forwards (n = 12) and defensemen (n = 7) were determined. Six sets of 3 × 80 m sprint, with two-minute passive recovery between two consecutive sets, were performed in RSSA-2. A three-minute passive recovery period between two consecutive sets was allowed in RSSA-3.

  • Ovarian cancer is more prevalent among Black women in West Africa compared to those in North America, and survival rates are lower for Black women than White women, with factors like histotype and age at diagnosis affecting outcomes.
  • The study analyzed data from Nigerian patients, Caribbean-born Blacks, and US-born Blacks, revealing that Nigerians had a higher percentage of germ cell and sex-cord stromal tumors, whereas Caribbean and US-born blacks had more cases of serous ovarian cancer.
  • Nigerians were diagnosed with epithelial ovarian cancers at a younger age compared to their Caribbean and US counterparts, with all Black women showing earlier diagnosis of germ cell and sex-cord stromal tumors than White women.

For non-kin cooperation to be maintained, individuals need to respond adaptively to the cooperative behaviour of their social partners. Currently, however, little is known about the biological responses of individuals to experiencing cooperation. Here, we quantify the neuroregulatory response of Trinidadian guppies (Poecilia reticulata) experiencing cooperation or defection by examining the transcriptional response of the oxytocin gene (oxt; also known as isotocin), which has been implicated in cooperative decision-making.
