ABSTRACT

This study was designed to (1) characterize the macronutrient composition of olive baboon (Papio anubis) milk, (2) compare baboon milk composition to that of rhesus macaques (Macaca mulatta), and (3) evaluate the association between the proportion of milk energy derived from protein and relative growth rate within anthropoid primates. A single milk sample was collected from each of eight lactating olive baboons ranging between 47- and 129-days postparturition and six rhesus macaques from 15- to 92-days living at the same institution under identical management conditions. Macronutrient composition (water, fat, protein sugar, and ash) was determined using standard techniques developed at the Nutrition Laboratory at the Smithsonian National Zoological Park. Baboon milk on average contained 86.0% ± 0.6% water, 4.7% ± 0.5% fat, 1.6% ± 0.04% protein, 7.3% ± 0.07% sugar, and 0.165% ± 0.007% ash. Baboon milk gross energy (GE) averaged 0.81 ± 0.04 kcal/g with 51.9% ± 2.6% from fat, 11.8% ± 0.7% from protein, and 36.2% ± 2.0% from sugar. Baboon milk demonstrated strong similarity to milk composition of the closely phylogenetically related rhesus macaque (86.1% ± 0.3% water, 4.1% ± 0.4% fat, 1.69% ± 0.05% protein, 7.71% ± 0.08% sugar, 0.19% ± 0.01% ash, and 0.78 kcal/g). There was no statistical difference between baboon and macaque milk in the proportions of energy from fat, sugar, and protein. Baboon milk can be described as a high sugar, moderate fat, and low protein milk with moderate energy density, which is consistent with their lactation strategy characterized by frequent, on-demand nursing and relatively slow life history compared to nonprimate mammal taxa. The milk energy from protein of both baboon and macaque (12.8% ± 0.3%) milk was intermediate between the protein milk energy of platyrrhine (19.3%-23.2%) and hominoid (8.9%-12.6%) primates, consistent with their relative growth rates also being intermediate. Compared to these cercopithecid monkeys, platyrrhine primates have both higher relative growth rates and higher milk energy from protein, while apes tend to be lower in both.

ABSTRACT

OBJECTIVES: Kawasaki disease (KD) is an acute, self-limited multisystemic vasculitis of unknown cause. Pulmonary involvement has been reported in case reports and limited small case series, which is not commonly recognized, especially in younger patients <1 year. Here, we describe clinical and radiological features of infants with KD-associated pulmonary involvement (KD-PI).

METHODS: Infants with KD were retrospectively enrolled during the period January 2017 to December 2020 in Shenzhen Children’s hospital. Patients with KD-PI were matched 1:1 based on current age and sex with KD patients without clinically apparent PI. Clinical data were collected from inpatient or outpatient medical records, including clinical manifestations, laboratory parameters, radiological findings, management, and prognosis.

RESULTS: Of 248 infant patients with KD, 34 presented with KD-PI. Of these, 22 had only subtle respiratory symptoms. Compared to KD controls, patients with KD-PI had significantly higher mean Kobayashi score (mean ± SD: 2.85 ± 1.94; p = .004), more had extremely high C-reactive protein (≥10 mg/dl: 11/34, 32.3%; p = .0115) and procalcitonin levels (˃1 ng/ml: 16/34, 47%; p = .039), and more were administered with adjuvant corticosteroids as initial therapy (38.2% vs. 2.9%; p = .0005). Abnormal chest radiological findings included peripheral consolidation (97.0%), localized pleural thickening (73.0%), lobular septal thickening (70.6%), ground-glass opacities (55.9%), linear opacities (35.3%), and pleural effusion (20.6%). No statistical difference was observed in the incidence of coronary artery abnormalities (CAAs) between two groups either in the acute phase or follow-up phase.

CONCLUSIONS: Higher use of adjuvant corticosteroids during initial therapy in our population may result in no difference in CAAs between the two groups despite higher levels of inflammation in KD-PI. Those results suggest that use of adjuvant corticosteroids may be beneficial in this population.

ABSTRACT

CONTEXT: Consumption of high-energy food has increased globally, thereby leading to an increase in many diseases. One strategy for addressing this is to make people aware of their energy intake through energy and fat labels. However, the effectiveness of this remains debatable.

OBJECTIVE: This review aims to pool the mixed outcomes of recent studies assessing the effect of energy and fat content labeling on food consumption pattern.

DATA SOURCES: Google Scholar, MEDLINE, and Cochrane Library databases were searched. Randomized controlled and quasi-experimental controlled trials published from 2014 to 2019 were included.

DATA EXTRACTION: Two reviewers screened 413 abstracts independently. Qualitative and quantitative data was extracted from 10 articles; meta-analysis was carried out on 6 of those studies.

RESULTS: The majority of the included papers were conducted in the regions of America, the Western Pacific, and Europe. Overall, the 6 studies claimed that labeling did not reduce the consumption of energy or fat. However, meta-analysis showed that fat and energy content labeling of food had a statistically significant effect on consumption. Subgroup analysis showed no difference with respect to types of labels, ie, context labeling vs traffic-light labeling, but energy content labels seemed to be more effective than fat content labels in influencing healthy food choices.

CONCLUSION: Energy and fat content labeling were shown to reduce the consumption of each significantly. However, the outcome was influenced by the study setting and the population concerned. There is a need for research in other regions in order to assess the global effectiveness of nutrition labels on food consumption.

ABSTRACT

BACKGROUND: Three rounds of a repeated cross-sectional serosurvey to estimate the change in seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were conducted from August to October 2020 in the state of Delhi, India, in the general population ≥5 y of age.

METHODS: The selection of participants was through a multistage sampling design from all 11 districts and 280 wards of the city-state, with multistage allocation proportional to population size. The blood samples were screened using immunoglobulin G (IgG) enzyme-linked immunosorbent assay kits.

RESULTS: We observed a total of 4267 (N=150 46), 4311 (N=17 409) and 3829 (N=15 015) positive tests indicative of the presence of IgG antibody to SARS-CoV-2 during the August, September and October 2020 serosurvey rounds, respectively. The adjusted seroprevalence declined from 28.39% (95% confidence interval [CI] 27.65 to 29.14) in August to 24.08% (95% CI 23.43 to 24.74) in September and 24.71% (95% CI 24.01 to 25.42) in October. On adjusted analysis, participants with lower per capita income, living in slums or overcrowded households and those with diabetes comorbidity had significantly higher statistical odds of having antibody positivity (p<0.01).

CONCLUSIONS: Nearly one in four residents in Delhi, India ≥5 y of age had the SARS-CoV-2 infection during August-October 2020.

ABSTRACT

BACKGROUND: Cardiorespiratory fitness is often impaired following stroke, and peak oxygen consumption (VO2peak) is an important prognostic value of all-cause mortality. The primary objective was to investigate whether functional walk tests assessed in the subacute phase after stroke added value in predicting VO2peak in chronic stroke, in addition to age, sex and functional dependency. Secondary objectives were to investigate associations between daily physical activity and functional walk tests, and with VO2peak in chronic stroke.

METHODS: This prospective cohort study included eligible participants originally included in the randomized controlled trial Life After Stroke. Functional walk tests, i.e., six-minute walk test (6MWT) and maximal gait speed, were assessed at inclusion and 18 months later. VO2peak [ml/kg/min] was assessed by a cardiopulmonary exercise test on a treadmill 20 months after inclusion. Daily physical activity was measured by a uniaxial accelerometer (activPAL) at 18-month follow-up.

RESULTS: Ninety-two community-dwelling individuals, with a mean (SD) age of 69.2 (10.6) years and 33 (35.9%) women, were included 3 months after stroke onset. Eighty-three (90.2%) participants had a modified Rankin Scale (mRS) score of 1 or 2, indicating functional independence. An overall assessment of four prediction models indicated the combination of age, sex, mRS and 6MWT as predictors to be the best fitted model in predicting VO2peak (adjusted R2 = 0.612). Secondary results showed statistically significant, but not clinically significant, associations between daily physical activity and functional walk tests, and with VO2peak.

CONCLUSIONS: 6MWT add significant value to the prediction of mean VO2peak in the chronic phase in mild strokes, in combination with age, sex and functional dependency. This prediction model may facilitate clinical decisions and rehabilitation strategies for mildly affected stroke survivors in risk of low levels of VO2peak. Future studies should validate the model in various stages after stroke and in patients moderately and severely affected.

ABSTRACT

OBJECTIVE: Synthesize studies of movement patterns and their association with hip pain, function/activity, and morphology in individuals with femoroacetabular impingement syndrome (FAIS).

METHODS: PubMed, SPORTDiscus, CINAHL, Embase, and Scopus databases were searched using predefined terms. Two authors independently reviewed abstracts and full texts. Studies were included if they enrolled individuals with FAIS, reported kinematic or kinetic data during movement tasks, and tested its associations with either hip pain, function/activity, or morphology. Exclusion criteria were: studies did not evaluate associations between movement patters and either pain, function/activity, or hip morphology. Additionally, studies with hip conditions other than FAIS, case reports, conference proceedings, review articles, and non-English studies were excluded. Descriptive consolidation and qualitative synthesis were performed for the included studies.

RESULTS: Of the 1155 potential studies, 5 studies met all eligibility criteria. Movement patterns were evaluated during walking (n = 4) and squatting (n = 1). Studies reported multiple associations between variables of interest. Statistically significant associations were identified between movement patterns and hip pain (n = 2), function/activity (n = 2), or morphology (n = 3). Significant associations included: increased hip flexion moment impulse during walking was associated with worse pain, increased hip flexion moment during walking was associated with worse hip function, decreased hip external rotation during gait and hip internal rotation during squat were associated with larger cam deformity, and increased hip flexion moment impulse during walking was also associated with more severe acetabular cartilage abnormalities.

CONCLUSIONS: Very little current evidence has evaluated the associations between altered movement patterns and hip pain, function/activity, or morphology in individuals with FAIS, and only low-intensity tasks have been tested. These studies found some preliminary associations between altered hip biomechanics and higher hip pain, worse hip function, and specific measures of hip morphology in individuals with FAIS.

IMPACT: This review is a first step in gaining a better understanding of movement patterns and their associations with hip pain, function/activity, and morphology, which could ultimately assist with the development of movement retraining interventions and potentially improve rehabilitation outcomes for those with FAIS.

ABSTRACT

BACKGROUND: Short inter-pregnancy interval is an interval of <24 months between the dates of birth of the preceding child and the conception date of the current pregnancy. Despite its direct effects on the perinatal and maternal outcomes, there is a paucity of evidence on its prevalence and determinant factors, particularly in Ethiopia. Therefore, this study assessed the prevalence and associated factors of short inter-pregnancy interval among pregnant women in Debre Berhan town, Northern Ethiopia.

METHODS: A community based cross-sectional study was conducted among a randomly selected 496 pregnant women in Debre Berhan town from February 9 to March 9, 2020. The data were collected by using an interviewer-administered questionnaire and analyzed using STATA (14.2) statistical software. To identify the predictors of short inter-pregnancy interval, multivariable binary logistic regression was fitted and findings are presented using adjusted odds ratio (AOR) with 95% confidence interval (CI).

RESULT: The overall prevalence of short inter-pregnancy interval (<24 months) among pregnant women was 205 (40.9%). Being over 30 years of age at first birth (AOR = 3.50; 95% CI: 2.12-6.01), non-use of modern contraceptive (AOR = 2.51; 95% CI: 1.23-3.71), duration of breastfeeding for less than 12 months (AOR = 2.62; 95% CI: 1.32-5.23), parity above four (AOR = 0.31; 95% CI: 0.05-0.81), and unintended pregnancy (AOR = 5.42; 95% CI: 3.34-9.22) were independently associated factors with short inter-pregnancy interval.

CONCLUSION: Despite the public health interventions being tried in the country, the prevalence of short inter-pregnancy interval in this study is high. Therefore, it implies that increasing contraceptive use and encouraging optimal breastfeeding might help in the efforts made to avert the problem.

ABSTRACT

BACKGROUND: Closing the gap of unmet for family planning is crucial to eliminate new pediatric HIV infections likewise to improve maternal and child health among reproductive-age women living with HIV. However, studies conducted on unmet need for family planning among reproductive-age women living with HIV showed inconsistent and non-conclusive findings on the magnitude of the problem. Moreover, there was no meta-analysis conducted in this area. So this systematic review and meta-analysis were conducted to estimate the pooled prevalence unmet need for family planning among reproductive-age women living with HIV in Ethiopia.

METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed to review both published and unpublished studies in Ethiopia. All studies in PubMed, Cochrane Library, Hinari, Google Scholar, CINAHL, and Global Health databases were searched. Meta-analysis was performed using STATA 14 software. The heterogeneity and publication bias were assessed using the I2 statistics and Egger regression asymmetry test, respectively. Forest plots were used to present the pooled prevalence with a 95% confidence interval (CI).

RESULTS: This review included 7 studies, and 3333 study participants. The pooled prevalence of unmet need for family planning among reproductive-age women living with HIV in Ethiopia was 25.13% (95%CI: 19.97, 30.29). The pooled prevalence of unmet need for spacing and limiting was 13.91% (95%CI: 10.11, 17.72) and 9.11% (95%CI: 6.43, 11.78), respectively.

CONCLUSIONS: One-fourths of reproductive-age women living with HIV had an unmet need for family planning. A variety of programmatic investments are needed to achieve more meaningful progress toward the reduction of unmet need for family planning among reproductive-age women living with HIV.

ABSTRACT

BACKGROUND: Over the years, sanitation programs over the world have focused more on household sanitation, with limited attention towards the disposal of children’s stools. This lack of attention could be due to the misconception that children’s stools are harmless. The current study examined the individual and contextual predictors of safe disposal of children’s faeces among women in sub-Saharan Africa (SSA).

METHODS: The study used secondary data involving 128,096 mother-child pairs of under-five children from the current Demographic and Health Surveys (DHS) in 15 sub-Saharan African countries from 2015 to 2018. Multilevel logistic analysis was used to assess the individual and contextual factors associated with the practice of safe disposal of children’s faeces. We presented the results as adjusted odds ratios (aOR) at a statistical significance of p< 0.05.

RESULTS: The results show that 58.73% (57.79-59.68) of childbearing women in the 15 countries in SSA included in our study safely disposed off their children’s stools. This varied from as high as 85.90% (84.57-87.14) in Rwanda to as low as 26.38% (24.01-28.91) in Chad. At the individual level, the practice of safe disposal of children’s stools was more likely to occur among children aged 1, compared to those aged 0 [aOR = 1.74; 95% CI: 1.68-1.80] and those with diarrhoea compared to those without diarrhoea [aOR = 1.17, 95% CI: 1.13-1.21]. Mothers with primary level of education [aOR = 1.42, 95% CI: 1.30-1.5], those aged 35-39 [aOR = 1.20, 95% CI: 1.12-1.28], and those exposed to radio [aOR = 1.23, 95% CI: 1.20-1.27] were more likely to practice safe disposal of children’s stools. Conversely, the odds of safe disposal of children’s stool were lower among mothers who were married [aOR = 0.74, 95% CI: 0.69-0.80] and those who belonged to the Traditional African Religion [aOR = 0.64, 95% CI: 0.51-0.80]. With the contextual factors, women with improved water [aOR = 1.13, 95% CI: 1.10-1.16] and improved toilet facility [aOR = 5.75 95% CI: 5.55-5.95] had higher odds of safe disposal of children’s stool. On the other hand, mothers who lived in households with 5 or more children [aOR = 0.89, 95% CI: 0.86-0.93], those in rural areas [aOR = 0.86, 95% CI: 0.82-0.89], and those who lived in Central Africa [aOR = 0.19, 95% CI: 0.18-0.21] were less likely to practice safe disposal of children’s stools.

CONCLUSION: The findings indicate that between- and within-country contextual variations and commonalities need to be acknowledged in designing interventions to enhance safe disposal of children’s faeces. Audio-visual education on safe faecal disposal among rural women and large households can help enhance safe disposal. In light of the strong association between safe stool disposal and improved latrine use in SSA, governments need to develop feasible and cost-effective strategies to increase the number of households with access to improved toilet facilities.

ABSTRACT

With the development of urbanisation and the increasing number of modern vehicles, traffic contamination has become an important source of environmental pollution. Most previous studies have focused on using roadside soil or plants to determine the spatial pattern of traffic pollutants along roads and the factors that influence this pattern, whereas few studies have reconstructed pollution histories caused by traffic using suitable methods. In this study, two gravity cores were obtained from Qianhu Lake, which is in the Zhongshan tourist area of Nanjing City and is distant from industrial areas. An accurate chronological framework covering the period from 1994 to 2014 was established using the correlation between the variation in grain size of the sediment cores and the variation in annual rainfall in Nanjing City. Moreover, magnetic and chemical parameters were also measured, and the results demonstrated that concentration-related magnetic parameters exhibited different correlations with different heavy metal concentrations. These correlations were significantly positive for Zn, Pb, and Co; weakly positive for Ni; absent for Cr; and negative for V. Combined with statistical data on industrial emissions and private cars in Nanjing City since 1994, the observed variations in magnetic susceptibility, anhysteretic remanent magnetisation, saturation isothermal remanent magnetisation, Zn, Pb, and Co, were controlled by traffic activities in the tourist area but not by industry. Therefore, the variations in these parameters record the traffic pollution history of the study area. Combined with the obtained chronological framework, the traffic-related pollution history could be divided into two stages: 1) from 1994 to 2003, when traffic-related pollution became increasingly serious because of the exponential increase in the number of private cars and the prosperity of tourism; 2) from 2003 to 2014, when traffic-related pollution continuously increased but at a much slower rate than in stage 1. This slower rate of increase was probably related to the maximum carrying capacity of the tourist area and technological innovations in automobile manufacturing, as well as improvements in fuels.
