Understanding the relationships between seed traits and germination responses is crucial for assessing natural regeneration, particularly in threatened ecosystems like the seasonally dry tropical forest (SDTF). This study explored links between seed traits (mass, volume, moisture content, and dispersal type), germination responses (germinability, germination speed (v¯), time to 50% of germination (T50), synchrony, and photoblastism), and physical dormancy (PY) in 65 SDTF species under experimental laboratory conditions...

BACKGROUND: Routine vaccination coverage in Latin America and the Caribbean declined prior to and during the coronavirus pandemic. We assessed the pandemic's impact on national coverage levels and analyzed whether financial and inequality indicators, immunization policies, and pandemic policies were associated with changes in national and regional coverage levels. METHODOLOGY: We compared first- and third-dose coverage of diphtheria-pertussis-tetanus-containing vaccine (DTPcv) with predicted coverages using time series forecast modeling for 39 LAC countries and territories...

Fusarium wilt of bananas (FWB) is a severe plant disease that leads to substantial losses in banana production worldwide. It remains a major concern for Cuban banana cultivation. The disease is caused by members of the soil-borne Fusarium oxysporum species complex. However, the genetic diversity among Fusarium species infecting bananas in Cuba has remained largely unexplored. In our comprehensive survey, we examined symptomatic banana plants across all production zones in the country, collecting 170 Fusarium isolates...

To examine whether the endometrial cancer (EC) survival disadvantage among Black populations is US-specific, a comparison between African descent populations from different countries with a high development index is warranted. We analyzed 28,213 EC cases from cancer registries in Florida (2005-2018) and Martinique (2005-2018)/Guadeloupe (2008-2018), French Caribbean islands. Kaplan-Meier and all-cause Cox proportional hazards models were used to compare survival. Models were stratified by EC histology type and the main predictor examined was race/ethnicity [non-Hispanic White (NHW) and Black (NHB) women in the US versus Black women residing in the Caribbean]...

BACKGROUND: Streptococcus pneumoniae is a leading cause of morbidity and mortality globally, causing bacteremic pneumonia, meningitis, sepsis, and other invasive pneumococcal diseases. Evidence supports nasopharyngeal pneumococcal carriage as a reservoir for transmission and precursor of pneumococcal disease. OBJECTIVES: To estimate the pneumococcal nasopharyngeal burden in all age groups in Latin America and the Caribbean (LAC) before, during, and after the introduction of pneumococcal vaccine conjugate (PVC)...

BACKGROUND: Hantavirus and dengue virus infections lead to diseases causing economic and public health concerns. Acute hantavirus infections can lead to similar clinical haemorrhagic signs as other endemic diseases including dengue and leptospirosis. METHODS: Using a retrospective case analysis of pregnant dengue and hantavirus disease patients with clinical reports and compatible clinical laboratory information during pregnancy, we report the first evidence of dengue and hantavirus infections and a case of dual dengue and hantavirus infection among pregnant women in the Caribbean...

B A rapid review was conducted to describe pesticide exposure assessment methodologies in Agricultural Work Contexts (AWC)s in Latin America and the Caribbean (LAC), in order to provide elements to reduce vulnerabilities within the agricultural population. A final number of 79 articles were selected from Medline via Pubmed, LILACS, and SciELO. In the region, family agriculture is the predominant form of agricultural production (72%) in informal agricultural work contexts (AWCs), which are characterized by small-scale diversified agricultural production, lower educational attainment, limited income, and a lack of social and healthcare security for the families...

In October 2023, several colonies of an alien soft coral species were reported on shallow reefs in southwest Puerto Rico. The soft coral was identified as a xeniid octocoral (species undetermined), resembling the octocoral Unomia stolonifera , which has invaded and overgrown reefs in Venezuela in recent years. To conclusively characterize the species of the invading xeniid, we employed multilocus barcoding targeting four genes (ND2, mtMutS, COI, and 28S) of three separate colonies across three locations in southwest Puerto Rico...

INTRODUCTION: Both immigrant and racialized status may be associated with the pursuit of living donor kidney transplant (LDKT). METHODS: This study was a secondary analysis of a convenience cross-sectional sample of patients with kidney failure in Toronto, obtained from our "Comprehensive Psychosocial Research Data System" research database. The exposures included racialized, immigrant, and combined immigrant and racialized status (White nonimmigrant, racialized nonimmigrant, White immigrant and racialized immigrant)...

OBJECTIVE: To document the process of introducing COVID-19 vaccines in a selection of Latin American and Caribbean countries, including the lessons learned and the strengths and weaknesses, and similarities and differences among programs. METHODS: This descriptive study is based on a systematic evaluation of the process of introducing COVID-19 vaccines in Argentina, Belize, Brazil, Costa Rica, Panama and Peru. Data were collected through a questionnaire distributed to key stakeholders...

INTRODUCTION: Hypertensive disorders during pregnancy are a major cause of severe morbidity, long-term disability, and death. Appropriate pharmacological treatment is essential in the management of these disorders.

This paper aims to identify how cognitive and emotional self-regulation (SR) processes in infants from 0 to 36 months are defined within the Latin American academic context. A systematic review based on the PRISMA methodology was implemented to review the conceptual and operational definition of SR, the type of study, the country of origin of the authors, and the reference to the adequacy of the research to the specific cultural context of Latin America. Twenty-two papers that met the selection criteria were selected...

BACKGROUND: Latin American and Caribbean countries are dealing with the combined challenges of pandemic-induced socicoeconomic stress and increasing public debt, potentially leading to reductions in welfare and health-care services, including primary care. We aimed to evaluate the impact of primary health-care coverage on child mortality in Latin America over the past two decades and to forecast the potential effects of primary health-care mitigation during the current economic crisis...

Anthropogenic pressure in areas of biodiversity importance erodes the integrity of the ecosystems they harbour, making features of biodiversity less buffered against extreme climatic events. We define the combination of these disturbances as compound events. We assessed compound event risk in protected areas (PAs) applying a spatial framework guided by criteria and quantitative thresholds associated with exposure to cyclones, drought, and intense human pressure. This assessment was used in a relational matrix to classify PAs with different risk of compound event occurrence...

INTRODUCTION: Surgical volume at Military Treatment Facilities (MTFs) has been gradually decreasing for roughly the past 2 decades. The Knowledge, Skills, and Abilities (KSA) Clinical Readiness Program linked surgical volume and readiness using a tool known as the KSA metric. However, the extent to which military medical missions contribute to the readiness of critical wartime specialties has not been evaluated using this metric. METHODS: In this study, a retrospective analysis was conducted using the surgical case logs from the US Naval Ship (USNS) Comfort missions in 2018 and 2019...

STUDY BACKGROUND: The effects of systemic racism were exacerbated and amplified throughout the COVID-19 pandemic. The resurgence of the "Black Lives Matter" movement in North America brought awareness to the public, especially white people, of the impacts of systemic racism in society and the urgent need for large-scale and institutional anti-racism work. PURPOSE: In collaboration with a local Community Health Centre, this research focused on identifying priority areas for tailored and co-developed anti-Black racism interventions in health services and community programming, as well as examining how purposeful relationships can be created with African, Caribbean, and Black (ACB) communities in London, Ontario...

With highly active antiretroviral therapy, HIV infection has become a treatable chronic disease. However, modifiable risk factors such as cigarette smoking continue to impact the morbidity and mortality of people with HIV (PWH). We assessed the prevalence and factors associated with cigarette smoking and motivation to quit among PWH in Western Jamaica. A cross-sectional study was conducted in which 392 adults seeking HIV care at health facilities in Western Jamaica completed an interviewer-administered questionnaire...

INTRODUCTION: It is not yet clear whether cardiac surgery by mini-incision (minimally invasive cardiac surgery [MICS]) is overall less painful than the conventional approach by full sternotomy (FS). A meta-analysis is necessary to investigate polled results on this topic. METHODS: PubMed®/MEDLINE, Cochrane CENTRAL, Latin American and Caribbean Health Sciences Literature (or LILACS), and Scientific Electronic Library Online (or SciELO) were searched for all clinical trials, reported until 2022, comparing FS with MICS in coronary artery bypass grafting (CABG), mitral valve surgery (MVS), and aortic valve replacement (AVR), and postoperative pain outcome was analyzed...
