RESUMO

The year 2021 marked a decade of holopelagic sargassum (morphotypes Sargassum natans I and VIII, and Sargassum fluitans III) stranding on the Caribbean and West African coasts. Beaching of millions of tons of sargassum negatively impacts coastal ecosystems, economies, and human health. Additionally, the La Soufrière volcano erupted in St. Vincent in April 2021, at the start of the sargassum season. We investigated potential monthly variations in morphotype abundance and biomass composition of sargassum harvested in Jamaica and assessed the influence of processing methods (shade-drying vs. frozen samples) and of volcanic ash exposure on biochemical and elemental components. S. fluitans III was the most abundant morphotype across the year. Limited monthly variations were observed for key brown algal components (phlorotannins, fucoxanthin, and alginate). Shade-drying did not significantly alter the contents of proteins but affected levels of phlorotannins, fucoxanthin, mannitol, and alginate. Simulation of sargassum and volcanic ash drift combined with age statistics suggested that sargassum potentially shared the surface layer with ash for ~50 d, approximately 100 d before stranding in Jamaica. Integrated elemental analysis of volcanic ash, ambient seawater, and sargassum biomass showed that algae harvested from August had accumulated P, Al, Fe, Mn, Zn, and Ni, probably from the ash, and contained less As. This ash fingerprint confirmed the geographical origin and drift timescale of sargassum. Since environmental conditions and processing methods influence biomass composition, efforts should continue to improve understanding, forecasting, monitoring, and valorizing sargassum, particularly as strandings of sargassum show no sign of abating.

RESUMO

Insectivorous Old World horseshoe bats (Rhinolophus spp.) are the likely source of the ancestral SARS-CoV-2 prior to its spillover into humans and causing the COVID-19 pandemic. Natural coronavirus infections of bats appear to be principally confined to the intestines, suggesting fecal-oral transmission; however, little is known about the biology of SARS-related coronaviruses in bats. Previous experimental challenges of Egyptian fruit bats (Rousettus aegyptiacus) resulted in limited infection restricted to the respiratory tract, whereas insectivorous North American big brown bats (Eptesicus fuscus) showed no evidence of infection. In the present study, we challenged Jamaican fruit bats (Artibeus jamaicensis) with SARS-CoV-2 to determine their susceptibility. Infection was confined to the intestine for only a few days with prominent viral nucleocapsid antigen in epithelial cells, and mononuclear cells of the lamina propria and Peyer's patches, but with no evidence of infection of other tissues; none of the bats showed visible signs of disease or seroconverted. Expression levels of ACE2 were low in the lungs, which may account for the lack of pulmonary infection. Bats were then intranasally inoculated with a replication-defective adenovirus encoding human ACE2 and 5 days later challenged with SARS-CoV-2. Viral antigen was prominent in lungs for up to 14 days, with loss of pulmonary cellularity during this time; however, the bats did not exhibit weight loss or visible signs of disease. From day 7, bats had low to moderate IgG antibody titers to spike protein by ELISA, and one bat on day 10 had low-titer neutralizing antibodies. CD4+ helper T cells became activated upon ex vivo recall stimulation with SARS-CoV-2 nucleocapsid peptide library and exhibited elevated mRNA expression of the regulatory T cell cytokines interleukin-10 and transforming growth factor-ß, which may have limited inflammatory pathology. Collectively, these data show that Jamaican fruit bats are poorly susceptible to SARS-CoV-2 but that expression of human ACE2 in their lungs leads to robust infection and an adaptive immune response with low-titer antibodies and a regulatory T cell-like response that may explain the lack of prominent inflammation in the lungs. This model will allow for insight of how SARS-CoV-2 infects bats and how bat innate and adaptive immune responses engage the virus without overt clinical disease.

RESUMO

BACKGROUND: Jamaican soil is abundant in heavy metals including mercury (Hg). Due to availability and ease of access, fish is a traditional dietary component in Jamaica and a significant source of Hg exposure. Mercury is a xenobiotic and known neuro-toxicant that affects children's neurodevelopment. Human glutathione S-transferase (GST) genes, including GSTT1, GSTM1, and GSTP1, affect Hg conjugation and elimination mechanisms. METHODS: In this exposure assessment study we used data from 375 typically developing (TD) 2-8-year-old Jamaican children to explore the association between environmental Hg exposure, GST genes, and their interaction effects on blood Hg concentrations (BHgCs). We used multivariable general linear models (GLMs). RESULTS: We identified the child's age, consumption of saltwater fish, canned fish (sardine, mackerel), string beans, grain, and starches (pasta, macaroni, noodles) as the environmental factors significantly associated with BHgCs (all P < 0.05). A significant interaction between consumption of canned fish (sardine, mackerel) and GSTP1 in relation to BHgC using either a co-dominant or recessive genetic model (overall interaction P = 0.01 and P < 0.01, respectively) indicated that consumption of canned fish (sardine, mackerel) was significantly associated with higher mean BHgC only among children with the GSTP1 Ile105Val, Ile/Ile [Ratio of mean Hg (95% CI) = 1.59 (1.09, 2.32), P = 0.02] and Ile/Val [Ratio of mean Hg (95% CI) = 1.46 (1.12, 1.91), P = 0.01] genotypes. CONCLUSIONS: Since this is the first study from Jamaica to report these findings, replication in other populations is recommended.

RESUMO

OBJECTIVES: Sickle cell disease (SCD) occurs in 2.8 % of our Jamaican antenatal population with homozygous HbSS being most associated with adverse maternal and perinatal outcomes. METHODS: A retrospective comparative analysis of HbSS, HbSC and HbSßThal pregnancy outcomes at the University Hospital of the West Indies (UHWI) between January 2012 and December 2022 was conducted. RESULTS: Of 120 patients (138 pregnancies), obesity occurred in 36 % (20/56) of the 'non-HbSS' group, i.e. HbSßThal (55 %, 5/9) and HbSC (32 %, 15/47) combined vs. 9.7 % of the HbSS (8/82). HbSS patients had more crises requiring transfusions, acute chest syndrome (ACS), maternal 'near-misses' (OR=10.7, 95 % 3.5-32.3; p<0.001), hospitalizations (OR 7.6, 95 % CI 3.4-16.9; p<0.001), low birth weight (LBW) neonates (OR 3.1, 1.1-8.9; p=0.037) and preterm birth (OR=2.6, 1.2-5.8; p=0.018) compared to HbSC and HbSßThal. Low dose aspirin was prescribed in 43 %. Logistic regression showed those NOT on aspirin (n=76) had more miscarriages (22 v. 2 %), were LESS likely to have a live birth (75 v. 95 % (0.2, 0.04-0.57, p=0.005)), but surprisingly had fewer painful crises (28 v. 46 % (0.5, 0.03-0.9, p=0.03)). CONCLUSIONS: HbSS women had a 10-fold excess of maternal near-misses. Additional research may further clarify the effects of aspirin on pregnancy outcomes as related to SCD genotypes.

RESUMO

Poor sleep and chronic illnesses have a bidirectional relationship where presence of one can worsen the other. Sickle cell disease (SCD) is associated with significant morbidity and early mortality. In this study, we examine sleep quality, its predictors, and its association with quality of life in Jamaican adults with SCD. This cross-sectional study evaluated 177 well adult SCD patients for sleep quality using The Pittsburgh Sleep Quality Index (PSQI) and quality of life using the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me). Multiple linear regression models examined the predictors of poor sleep quality. The mean global PSQI score was 6.9 (SD 4.2) with 56.5% having poor sleep quality. Women had significantly worse scores for sleep efficiency (p 0.005), sleep latency (p 0.03) and higher use of sleeping medications (p 0.02). Those overweight/obese had significantly worse subjective sleep quality (p 0.001) and sleep efficiency (p 0.05). In multivariate regression analysis, overweight individuals had poorer sleep quality (OR: 2.9; 95% C.I.: 1.07, 7.88) than those with normal weight whereas those unemployed and looking for a job had lower prevalence of poor sleep quality (OR 0.2; 95% C.I.: 0.05, 0.77) compared to employed individuals. Participants with good sleep quality had significantly better functioning in all 5 domains of the ASCQ-Me. In conclusion, persons with SCD who are overweight or obese are at increased risk of poor sleep which can negatively affect quality of life. Patient populations and healthcare providers will need to manage the emerging burden of overweight/obesity.

RESUMO

Birth cohort studies across the world have yielded information that has been used to inform policy and programme decisions that have improved the health and well-being of populations. A few such studies have been conducted in low- and middle-income countries due to funding, methodological and other challenges. This paper briefly reviews the methods of comprehensive birth cohort studies with extensive follow-up of participants through the life course conducted in low- and middle-income countries. It then reviews the first Jamaican birth cohort study of 1986 and discusses the methodological advances in implementing JA KIDS, the second Jamaican birth cohort study conducted in 2011. The aims and methods of JA KIDS are described in detail.

RESUMO

There is very little compelling evidence that household size negatively affects child development. In this study, the effects of household size on child development were analysed using data collected for a sample of 1311 four-year-old Jamaican children. Children's development was assessed using the Griffiths Mental Development Scales across six developmental domains: locomotor, personal-social, language, coordination, performance and practical reasoning. The findings suggest that children's locomotor and personal-social development are negatively affected by household crowding, with no significant effects observed for other domains. Additional results show that these adverse effects are strongest if the child lives in a single room compared to a separately detached house. This evidence speaks to the need to tailor policies towards access to good housing infrastructure and the provision of recreational spaces to encourage play and social interaction among children.

RESUMO

Violence against young children is known to have detrimental short and long-term effects. Yet, few studies investigate the prevalence of violence against young children, particularly very young children under the age of 2 years. This paper reports on the prevalence of violence against young children in Jamaica using data obtained from the JA KIDS birth cohort study that undertook pre-enrolment of pregnant mothers in the antenatal period and followed full or sub-samples of parents and children at 9-12 months, 18-22 months and 4-5 years. Violence in pregnancy was experienced by 6.1% of pre-enrolled mothers. As many as 43.1% of Jamaican children ages 9-12 months were shouted at, and almost 30% were slapped. Physical and emotional violence increased with age, and by 4-5 years, approximately 90% of children experienced physical and emotional violence. Non-violent methods, primarily explaining and reasoning with children, were also reported by more than 95% of parents at 4-5 years. Corporal punishment was the most common form of violence experienced, but young children also witnessed hurtful physical and emotional violence between mothers and their partners and lived in communities in which there were violent events. Strategies to reduce young children's experiences as victims and witnesses of violence are discussed.

RESUMO

OBJECTIVES: To evaluate the effectiveness of newborn screening for sickle cell disease in eastern Jamaica by determining what proportion of screen-positive infants were registered with the Sickle Cell Unit by 2 months (60 days) of age and identifying parents' perceptions of facilitators and barriers impacting age at registration. STUDY DESIGN: This cross-sectional study used a mixed method approach. Ages at diagnosis confirmation and first clinic visit were recorded for screen-positive infants born between February 1, 2015, and November 15, 2017. All parents were invited to complete the survey, and early and late attendees were invited to participate in the qualitative aspect of the study. A researcher-designed questionnaire and an interview guide based on the Capability, Opportunity, Motivation, Behavior, and health belief models examined factors that may affect time to registration. Quantitative data were analyzed to yield descriptive statistics using Stata®v14. All interview data were coded. Similar codes were grouped together into themes. RESULTS: Most (97.7%) of the 133 screen-positive infants had their diagnosis confirmed. Only 40% had their first clinic visit by age 60 days. Denial of the diagnosis, poor communication, and the costs of treatment and transportation were perceived barriers to registration, whereas family support was a facilitator. CONCLUSIONS: Diagnosis confirmation was almost universal, but most infants did not attend clinic by 2 months of age. In-depth interviews have identified several facilitators and barriers that can be targeted to improve early registration.

RESUMO

Gene flow and reticulation are increasingly recognized as important processes in the diversification of many taxonomic groups. With the increasing ease of collecting genomic data and the development of multispecies coalescent network approaches, such reticulations can be accounted for when inferring phylogeny and diversification. Caribbean Anolis lizards are a classic example of an adaptive radiation in which species have independently radiated on the islands of the Greater Antilles into the same ecomorph classes. Within the Jamaican radiation at least one species, Anolis opalinus, has been documented to be polyphyletic in its mitochondrial DNA, which could be the result of an ancient reticulation event or incomplete lineage sorting (ILS). Here, we generate mtDNA and genotyping-by-sequencing (GBS) data and implement gene tree, species tree, and multispecies coalescent network methods to infer the diversification of this group. Our mtDNA gene tree recovers the same relationships previously inferred for this group, which is strikingly different from the species tree inferred from our GBS data. Posterior predictive simulations suggest that our genomic data violate commonly adopted assumptions of the multispecies coalescent model (MSCM), so we use network approaches to infer phylogenetic relationships. The inferred network topology contains a reticulation event but does not explain the mtDNA polyphyly observed in this group; however, coalescent simulations suggest that the observed mtDNA topology is likely the result of past introgression. How common a signature of gene flow and reticulation is across the radiation of Anolis is unknown; however, the reticulation events that we demonstrate here may have allowed for adaptive evolution, as has been suggested in other, more recent, adaptive radiations. [Adaptive radiation; hybridization; introgression; multispecies network coalescent; posterior predictive simulation.].

RESUMO

OBJECTIVE: Prior studies have demonstrated survival differences between Black women with endometrial cancer (EC) born in the US and Caribbean. Our objective was to determine if country of birth influences EC overall survival (OS) in disaggregated subpopulations of Black women. METHODS: Using the Florida Cancer Data System, women with EC diagnosed from 1981 to 2017 were identified. Demographic and clinical information were abstracted. Women who self-identified as Black and born in the US (USB), Jamaica (JBB), or Haiti (HBB) were included. Statistical analyses were performed using chi-square, Cox proportional hazards models, and Kaplan-Meier methods with significance set at p < 0.05. RESULTS: 3817 women met the inclusion criteria. Compared to USB, JBB and HBB had more high-grade histologies, more advanced stage disease, had a greater proportion of uninsured or Medicaid insured, and had a higher proportion of women who received chemotherapy (all p < 0.05). In multivariate analyses, age (HR 1.03 [1.02-1.05]), regional stage (HR 1.52 [1.22-1.89]), distant stage (HR 3.73 [2.84-4.89]), lymphovascular space invasion (HR 1.96 [1.61-2.39]), receipt of surgery (HR 0.47 [0.29-0.75]), and receipt of chemotherapy (HR 0.77 [0.62-0.95]) were independently associated with OS. Compared to USB, Haitian nativity was an independent negative predictor of OS when evaluating all histologies together (HR 1.54 [1.18-2.00]) and for endometrioid EC specifically (HR 1.77 [1.10-2.83]). Among women with serous EC, HBB had markedly worse median OS (18.5 months [13.4-46.5]) relative to USB (29.9 months [26.3-35.9]) and JBB (41.0 months, [34.1-82.6], p = 0.013). CONCLUSION: Country of birth is associated with endometrial cancer survival in Black women, with HBB demonstrating worse outcomes.

RESUMO

BACKGROUND: Stroke mimics are non-vascular conditions that present with acute focal neurological deficits, simulating an acute ischemic stroke. Susumber berry (SB) toxicity is a rare cause of stroke mimic with limited case reports available in the literature. OBJECTIVES: We report four new cases of SB toxicity presenting as stroke mimic, and we performed a systematic review. METHODS: MEDLINE/EMBASE/WoS were searched for "susumber berries," "susumber," or "solanum torvum." RESULTS: 531 abstracts were screened after removal of duplicates; 5 articles and 2 conference abstracts were selected describing 13 patients. A total of 17 patients who ingested SB and became ill were identified, including our 4 patients. All but one presented with acute neurologic manifestation; 16 (94%) presented with dysarthria, 16 (94%) with unstable gait, 8 (47%) with nystagmus/gaze deviation, 10 (59%) with blurry vision, and 5 (29%) with autonomic symptoms. Six (35%) required ICU admission, and 3 (18%) were intubated. Fourteen (82%) had a rapid complete recovery, and 3 were hospitalized up to 1 month. CONCLUSIONS: SB toxicity can cause neurological symptoms that mimic an acute stroke typically with a posterior circulation symptom complex. Altered SB toxins (from post-harvest stressors or temperature changes) might stimulate muscarinic/nicotinic cholinergic receptors or inhibit acetylcholinesterase, causing gastrointestinal, neurological, and autonomic symptoms. In cases of multiple patients presenting simultaneously to the ED with stroke-like symptoms or when stroke-like symptoms fail to localize, a toxicological etiology (such as SB toxicity) should be considered.

RESUMO

BACKGROUND: Recent data on the prevalence of H. pylori infection in Jamaica are lacking. It is postulated that there has been a decline in the prevalence of H. pylori infection and its associated complications. We determined sociodemographic characteristics, prevalence of H. pylori infection and clinical outcomes among adults undergoing esophagogastroduodenoscopy (EGD) and histology at the University Hospital of the West Indies (UHWI) between May 2018 and December 2020. MATERIALS AND METHODS: A cross-sectional study of patients (≥18 years old), who underwent EGD and histological evaluation for H. pylori infection, was conducted. Associations of H. pylori positivity and gastric cancer with sociodemographic/clinical variables and endoscopic findings were determined by stepwise logistic regression using backward selection. Unadjusted and adjusted odds ratios with related 95% confidence intervals (Cis) were calculated for H. pylori positivity and gastric cancer status. RESULTS: There were 323 participants (mean age 58.6 ± 17.8 years, 54.2% females). H. pylori prevalence was 22.2% (n = 70 of 315), 5.6% had gastric neoplasia (GN), 15.5% gastric atrophy, 11.4% intestinal metaplasia and 3.7% dysplasia on histology. Mucositis (64.5%), gastric ulcer (14.9%), and duodenal ulcer (13.9%) were the most common endoscopic findings. Participants with peptic ulcer disease (PUD) (unOR = 4.0; p = .017), gastric cancer (unOR = 9.5; p = .003), gastric atrophy (unOR = 12.8; p < .001), and intestinal metaplasia (unOR = 5.0; p < .001) had a significantly higher odds of being H. pylori positive, but after multivariable analyses only gastric atrophy remained significant (aOR = 27.3; p < .001). Participants with mucositis had a significantly lower odds of gastric cancer (unOR 0.1; p = .035) while participants with dysplasia had significantly higher odds (unOR 8.0; p = .042), but these were no longer significant after multivariable analyses (aOR = 0.2; p = .156 and aOR = 18.9; p = .070, respectively). CONCLUSIONS: Histology based prevalence of H. pylori infection is lower than previously reported in Jamaica. Gastric atrophy is a significant predictor of H. pylori positivity.

RESUMO

Increased life expectancy among persons living with HIV (PLHIV) has increased the desire for parenthood. It is therefore important that PLHIV and health care providers (HCPs) are aware of the available assisted reproduction services (ARS) for PLHIV facing infertility or unsuppressed viremia. Through secondary data analysis we identified PLHIV who were actively trying to conceive and their knowledge of ARS. As specialized fertility care for PLHIV is managed by Obstetrician/Gynecologists (Ob/Gyns), they were surveyed regarding their attitudes towards working with PLHIV and their awareness and knowledge of ARS with a self-administered questionnaire. In this cross-sectional study, 251 PLHIV and 102 Ob/Gyns were recruited and interviewed using a semi-structured questionnaire. Although most Ob/Gyns (81%) reported being supportive of PLHIV having children, 85% counseled against pregnancy, particularly persons in HIV serodifferent relationships. Significantly more PLHIV under 40 years compared to those over 40 years had heard about ARS (59% vs. 43%, p = .007). Ob/Gyns were more knowledgeable of expensive ARS, while PLHIV's knowledge was more restricted to cheaper more accessible ones. In conclusion Ob/Gyns knowledge gaps and underlying stereotypes may present barriers to PLHIV's uptake of ARS. Additionally, virologically unsuppresed persons in HIV serodifferent relationships may be vulnerable as Ob/Gyns were less supportive of them.

RESUMO

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of mortality across the Caribbean and similar regions. Structural determinants include a marked increase in the dependency on food imports, and the proliferation of processed foods, including sugar-sweetened beverages (SSBs). We focused on Jamaica as a case study and the health challenge of SSBs, and situated contemporary actions, experiences and policies within their historical context to investigate underlying drivers of commercial determinants of health and attempts to counter them. We asked: how can a historical perspective of the drivers of high level SSB consumption in Jamaica contribute to an enhanced understanding of the context of public health policies aimed at reducing their intake? METHODS: An ethnographic approach with remote data collection included online semi-structured interviews and workshops with 22 local experts and practitioners of health, agriculture and nutrition in Jamaica and attending relevant regional public webinars on SSBs and NCD action in the Caribbean. Our analysis was situated within a review of historical studies of Caribbean food economies with focus on the twentieth century. Jamaican and UK-based researchers collected and ethnographically analysed the data, and discussed findings with the wider transdisciplinary team. RESULTS: We emphasise three key areas in which historical events have shaped contextual factors of SSB consumption. Trade privileged sugar as a cash crop over food production during Jamaica's long colonial history, and trade deregulation since the 1980s through structural adjustment opened markets to transnational companies. These changes increased Jamaican receptiveness to the mass advertisement and marketing of these companies, whilst long-standing power imbalances hampered taxation and regulation in contemporary public health actions. Civil society efforts were important for promoting structural changes to curb overconsumption of SSBs and decentring such entrenched power relations. CONCLUSION: The contemporary challenge of SSBs in Jamaica is a poignant case study of commercial determinants of health and the important context of global market-driven economies and the involvement of private sector interests in public health policies and governance. Historically contextualising these determinants is paramount to making sense of the sugar ecology in Jamaica today and can help elucidate entrenched power dynamics and their key actors.

RESUMO

ABSTRACT: Alopecia is common in Jamaican, primarily Afro-Caribbean patients. We performed a retrospective review examining the histopathologic alopecia diagnoses over ∼5 years. Requisition forms and pathology reports were assessed. Demographic/clinical/technical/diagnostic and pathologic findings of chronicity/severity data were recorded. Three hundred thirty-eight biopsies were included. The majority were 4 mm punches, grossed horizontally. The F:M ratio was 4.8:1, mean age = 42.7 years, and mean duration of alopecia = 5.1 years. Cicatricial alopecias (CAs) predominated over non-CAs (NCAs). The top 10 diagnoses were central centrifugal CA (21.9%), folliculitis decalvans (10.9%), multifactorial alopecias (10.1%), pattern hair loss (8%), lichen planopilaris (7.1%), alopecia areata (6.2%), discoid lupus erythematosus (6.2%), nonclassifiable lymphocytic scarring alopecias (5.6%), frontal fibrosing alopecia (5.3%), and nonspecific NCAs (5%). This contrasted with other richly pigmented populations where discoid lupus erythematosus predominates. Other interesting findings included relatively frequent folliculitis decalvans and lichen planus pigmentosus in 40.9% of frontal fibrosing alopecia cases. Scarring/nonscarring clinicopathologic congruence occurred in 83.4%.Regarding histopathologic features of severity/chronicity, CAs had markedly decreased hair counts. Perifollicular fibrosis affecting retained hairs occurred in 75% of CAs, moderate to severe in >50% of these. Approximately 50% of NCA samples demonstrated advanced miniaturization (T:V ratio <2:1). In our study, relatively young women with chronic hair loss and CA are most frequently biopsied. Central centrifugal CA is the most common diagnosis. Local features of chronic/severe disease are seen microscopically. Clinical impression of scarring/nonscarring correlates well with histopathology.

RESUMO

BACKGROUND: Using a validated instrument to measure palliative care (PC) educational needs of health professionals is an important step in understanding how best to educate a well-versed PC workforce within a national health system. The End-of-life Professional Caregiver Survey (EPCS) was developed to measure U.S. interprofessional PC educational needs and has been validated for use in Brazil and China. As part of a larger research project, this study aimed to culturally adapt and psychometrically test the EPCS among physicians, nurses, and social workers practicing in Jamaica. METHODS: Face validation involved expert review of the EPCS with recommendations for linguistic item modifications. Content validation was carried out by six Jamaica-based experts who completed a formal content validity index (CVI) for each EPCS item to ascertain relevancy. Health professionals practicing in Jamaica (n = 180) were recruited using convenience and snowball sampling to complete the updated 25-item EPCS (EPCS-J). Internal consistency reliability was assessed using Cronbach's [Formula: see text] coefficient and McDonald's [Formula: see text]. Construct validity was examined through confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). RESULTS: Content validation led to elimination of three EPCS items based on a CVI < 0.78. Cronbach's [Formula: see text] ranged from 0.83 to 0.91 and McDonald's [Formula: see text] ranged from 0.73 to 0.85 across EPCS-J subscales indicating good internal consistency reliability. The corrected item-total correlation for each EPCS-J item was > 0.30 suggesting good reliability. The CFA demonstrated a three-factor model with acceptable fit indices (RMSEA = 0.08, CFI = 0.88, SRMR = 0.06). The EFA determined a three-factor model had the best model fit, with four items moved into the effective patient care subscale from the other two EPCS-J subscales based on factor loading. CONCLUSIONS: The psychometric properties of the EPCS-J resulted in acceptable levels of reliability and validity indicating that this instrument is suitable for use in measuring interprofessional PC educational needs in Jamaica.

RESUMO

OBJECTIVE: The study aimed to determine the outcome of babies born to women ≥40 years in a Jamaican birth cohort. STUDY DESIGN: Maternal demographic data and neonatal data for women ≥40 years who delivered live singleton babies and their younger counterparts aged 20 30 years were extracted from the JA KIDS birth cohort dataset. Outcome measures were preterm birth, low birth weight, very low birth weight, extremely low birth weight, macrosomia, a low 5-minute Apgar score <7, admission to the neonatal unit, and neonatal death. Descriptive analyses were performed; statistical significance was taken at the level p <0.05. RESULTS: A total of 5,424 women and their babies were entered into the study, 5,099 (94%) women were aged 20 to 30 years (mean age ± standard deviation [SD]: 24.5 ± 3.2 years) and 325 (6%) were aged ≥40 years (mean age ± SD: 41.5 ± 1.6 years). A greater percentage of preterm babies (18%) were born to women ≥40 years than to their younger counterparts (14%; p = 0.04). There was no difference in the proportion of low birth weight infants, very low birth weight infants, or extremely low birth weight infants born between the two groups (p > 0.05). There was also no significant difference in the proportion of babies who were macrosomic and in those who had a low 5-minute Apgar score <7. There were 866 (16%) neonatal admissions, 67/325 (21%) of these babies were born to women aged ≥40 years and 799/5,099 (16%) were born to their younger counterparts (p = 0.01). The commonest reason for admission was prematurity. While 60 babies died, there was no significant difference between both groups with 56 (1%) born to women 20 to 30 years and 4 (1%) born to women ≥40 years (p = 0.48). CONCLUSION: Adverse outcomes noted for babies born to women ≥40 years were prematurity and the need for neonatal admission. However, no excess mortality was recorded. KEY POINTS: · Women 40 years and older are more likely to have a chronic illness such as hypertension and diabetes and to have an operative delivery.. · Babies born to women 40 years and older are more likely to be late premature infants and require neonatal admission.. · However, there is no increased risk of neonatal mortality..

RESUMO

BACKGROUND: Violence against children (VAC) is a global public health problem, and parenting programmes are a key strategy to reduce VAC at home. We developed and evaluated a preschool-based, early childhood, violence prevention, parenting programme (the Irie Homes Toolbox) in Jamaica and reported significant reductions in parents' use of VAC [Effect size (ES) = -0.29] and increases in parents' positive practices (ES = 0.30). This study presents qualitative findings on the mechanisms of action of the programme. METHODS: As part of a cluster randomized trial, 115 parents from nine preschools participated in the Irie Homes Toolbox parenting programme. The programme consisted of eight 90-min sessions with groups of six parents and focussed on strengthening parent-child relationships, understanding children's behaviour, using appropriate discipline strategies and understanding and managing emotions. We conducted in-depth, semi-structured interviews with a stratified random sample of 28 parents (two to four parents per school) and with nine preschool teachers (one teacher per preschool). Topic guides were developed to explore participants' perspectives of the mechanisms of action of the programme. All interviews were audio-recorded and transcribed, and data were analysed using the framework approach. RESULTS: The most salient direct pathways to reduced VAC by both parent and teacher reports were through parents' use of alternative strategies to manage child misbehaviour and through improved parent well-being, especially parents' self-management skills. Other factors leading to reduced VAC by parents, reported by both parents and teachers, included self-identification as an 'Irie parent', use of proactive parenting strategies and improved child behaviour. Parents reported that the main factors leading to continued use of VAC were their inconsistency in using positive discipline strategies and poor emotional self-regulation. CONCLUSION: Reports from participating parents and preschool teachers indicate that contents related to parental self-management and how to use positive discipline strategies to manage child misbehaviour were important factors on the pathway to reduced VAC.
