Further, adolescents with low motor competence had a risk six times higher of being overweight/obese (odds ratio = 6.832, p  less then  0.001, 95% confidence interval = 2.477-18.845). Conclusions This study showed that a low level of motor competence is linked to the odds of being overweight/obese in adolescents. This is a concern given the high prevalence of low motor competence in youth worldwide. However, our cross-sectional design does not allow the determination of causal mechanisms. Regardless, we reinforce the recommendation that young people should establish behavioral patterns favorable to adolescent health, including adequate levels of motor competence.Objective To estimate the incidence rate and associated risk factors of severe maternal morbidity (SMM) in commercially and Medicaid-insured women. Methods This was a retrospective cohort study of women with a live inpatient delivery recorded in 2016 in the MarketScan® databases for commercially insured and Medicaid populations. The incidence of SMM, defined by the Center for Disease Control and Prevention's algorithm of International Classification of Diseases, 10th edition diagnostic and procedural codes, was determined. Measurements also included the association of SMM in bivariate analyses with patient characteristics and the association of SMM with delivery type, gestation type, maternal age, and race in multivariate logistic regression analysis, adjusted for pre-existing conditions and pregnancy-related complications. Results The incidence of SMM per 10,000 deliveries was 111.4 in the Commercial and 109.6 in the Medicaid population. The most frequent SMM indicators were eclampsia and blood transfusion in the Commercial population (35.0 and 25.7 per 10,000 deliveries, respectively) and eclampsia and adult respiratory distress syndrome in the Medicaid population (45.5 and 14.9 per 10,000 deliveries, respectively). A cesarean delivery was associated with SMM in both Commercial (odds ratio [OR] 3.37; 95% confidence interval [CI] 1.51-1.84) and Medicaid populations (OR 1.99; 95% CI 1.80-2.17). A multifetal gestation was also associated with SMM in both Commercial (OR 3.37; 95% CI 2.80-4.10) and Medicaid populations (OR 2.26; 95% CI 1.86-2.75). Conclusion SMM occurred in 1.1% of live inpatient deliveries. A cesarean delivery, multifetal gestation, race, region, and several pre-existing comorbidities and obstetric complications were associated with SMM.Timely outbreak detection and response can translate into illnesses averted and lives saved. As such, timeliness is an important criterion for evaluating performance of infectious disease surveillance systems. Through the use of clearly defined outbreak milestones, timeliness metrics can capture the speed of outbreak detection, verification, response, and other key actions across the timeline of an outbreak and evaluate progress over time. In this article, we describe a series of country-level pilot studies designed to assess the feasibility and utility of tracking timeliness metrics and highlight key findings. We then discuss subsequent efforts to develop a timeliness metrics measurement framework through expert consultation and provide recommendations for implementation. National surveillance programs, international agencies, and donor organizations can use timeliness metrics to identify gaps in surveillance performance and track progress toward improved global health security.In this study, we isolated a group of viruses that can cause a cytopathic effect in BHK-21 cells from sandfly specimens collected in Yangquan County, Shanxi Province, central China. The representative virus strain is SXYQ1860 and, with increased viral injection, the suckling mice became ill and died, with viral titers continually increasing. The results of molecular genetic evolution analysis of the three gene segments of the virus, L, M, and S, indicate that the newly isolated viruses from Yangquan County are the same as the Wuxiang virus (WUXV) previously isolated from sandflies collected in Wuxiang county, China. This is the first time that the WUXV was also isolated outside Wuxiang County. Therefore, strengthening the surveillance of neglected sandflies and the viruses they transmit to help prevent and control arboviruses and the associated diseases is essential for public health.Previous research has demonstrated a high prevalence of Coxiella burnetii in the bulk tank milk on large industrial dairy farms of the central and eastern European region. The aim of this survey was to estimate the prevalence of specific IgG antibodies to C. burnetii proving previous infection among dairy farm workers and to determine the possible risk factors. Serum samples from veterinarians, inseminators, animal caretakers, milking parlor workers, and herd managers working on dairy farms were tested for the presence of IgG to phase I and phase II of C. burnetii using an indirect microimmunofluorescence assay. Antibodies phase II to C. burnetii were detected in 59 out of 70 individuals tested (84.3%). AG-270 molecular weight All occupational groups are highly exposed to C. burnetii infection. Veterinarians, inseminators, and animal caretakers had 100% seropositivity rate of phase II, whereas the seropositivity rate found among herd managers and milking parlor workers was 71.4% and 47%, respectively. The findings of this survey suggest that the risk of C. burnetii infection is correlated with cattle density in the large dairy farms and also with occupational groups.HIV-related stigma is a known barrier to retention in care. However, no large-scale, multi-site studies have prospectively evaluated the effect of internalized stigma on retention in care. The Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort study integrates medical record and survey data from people living with HIV (PLWH) seen in HIV primary care clinics across the United States, and assesses internalized stigma yearly using a validated 4-item Likert scale. We used multivariable logistic regression models to evaluate associations between mean internalized stigma and two prospective retention in care outcomes keeping the next primary care appointment and keeping all scheduled primary care appointments in the 12 months following stigma assessment. From February 2016 to November 2017, 5968 PLWH completed the stigma assessment and had adequate follow-up time. Mean stigma was 1.9 (standard deviation 1.08). Increased mean stigma scores were associated with decreased odds of attending the next primary care appointment [adjusted odds ratio (aOR) = 0.93, 95% confidence interval (CI) 0.88-0.99, p = 0.02], and all primary care appointments in the subsequent 12 months (aOR = 0.94, 95% CI 0.89-0.99, p = 0.02). In both models, younger age and Black race were also independently associated with suboptimal appointment attendance. There was no support for interactions between internalized stigma and covariates. Internalized HIV stigma had an independent negative effect on the odds of subsequent appointment attendance. This study highlights the importance of identifying even low levels of internalized stigma. Interventions to address internalized HIV stigma are critical to supporting retention in care and improving clinical outcomes.It is well documented and generally accepted that human clearance (CL) of unconjugated single-strand antisense oligonucleotides (ASOs) can be directly predicted from monkeys by body weight (BW) on a mg/kg dose basis. However, the scaling for triantennary N-acetyl galactosamine (GalNAc3)-conjugated ASOs has not been fully established. In this study, we retrospectively analyzed pharmacokinetic data from 9 GalNAc3-conjugated and 12 unconjugated single-stranded ASOs (ten 2'-methoxyethyl and two 2', 4'-constrained ethyl ASOs) to identify an appropriate allometric scaling factor between the two species. In addition, we compared the trough plasma concentrations (Ctrough, a surrogate for tissue exposure) between monkeys and humans at comparable dose levels, aiming at predicting tissue distribution in humans from monkeys. Overall, the median plasma CL ratios (monkey CL/human CL) were 1.05 and 0.94 when CL was normalized by BW, as compared with 0.33 and 0.29 when CL was normalized by body surface area (BSA) for the 12 unconjugated and 9 GalNAc3-conjugated ASOs, respectively. Similarly, the median Ctrough ratios (Ctrough in monkeys/Ctrough in humans) were 0.96 and 1.71, respectively, when Ctrough was normalized by mg/kg dose as compared with 3.10 and 5.50 when Ctrough was normalized by mg/m2 dose for the same unconjugated and conjugated ASOs, respectively. Equivalent CL and dose-normalized plasma Ctrough between monkeys and humans suggest similar pharmacokinetic profiles and tissue distribution between the two species on a per kilogram BW basis. In conclusion, human CL and plasma Ctrough (a surrogate of tissue distribution) can be directly predicted (11 or within twofold) from monkeys by BW on a mg/kg dose basis but these parameters can be under- or over-predicted by BSA on a mg/m2 dose basis. These results provide evidence for single species scaling from monkeys to humans directly and, thus, they can facilitate early human dose prediction in ASO drug development.
The COVID-19 pandemic is a colossal challenge for global health; nonetheless, specific subgroups face considerably higher risks for infection and mortality. Among patients with malignant diseases, those with hematologic neoplasms are at a higher risk for poor outcomes. The objective of this study was to register treatment modifications associated with the COVID-19 pandemic and their short-term consequences in Latin America.

Multicenter, prospective, observational, cohort study including patients older than 14 years from 14 centers in four countries (Mexico, Peru, Guatemala, and Panama) who had a confirmed diagnosis of acute leukemia, and who were undergoing active treatment since the first COVID-19 case in each country until the cutoff on July 15, 2020.

We recruited 635 patients. Treatment modifications because of the COVID-19 pandemic were reported in 40.8% of cases. The main reason for such modifications was logistic issues (55.0%) and the most frequent modification was chemotherapy delay (42.0%). A total of 13.1% patients developed COVID-19 disease, with a mortality of 37.7%. Several factors were identified as independently associated with mortality, including a diagnosis of acute myeloid leukemia (odds ratio 2.38 [95% CI, 1.47 to 3.84];
< .001), while the use of telemedicine was identified as a protective factor (odds ratio 0.36 [95% CI, 0.18 to 0.82];
= .014).

These results highlight the collateral damage of COVID-19 in oncology patients.

The incidence of symptomatic brain metastasis at diagnosis in non-small-cell lung cancer (NSCLC) is 5%-10%, and up to 40% develop during the disease course. There is a paucity of data supporting the role of brain imaging at diagnosis in asymptomatic cases particularly from resource-constraint settings. Here, we present our experience of mandatory baseline brain imaging with contrast-enhanced computed tomography (CECT) scans of all patients with NSCLC.

This was a prospective observation study of patients with NSCLC with mandatory baseline brain CECT and a CNS examination. All histology proven patients with NSCLC diagnosed between January 2018 and October 2019 were included irrespective of stage.

A total of 496 patients were enrolled. The median age was 57 years (range, 23-84) with majority being males (75%) and smokers (66%). The prevalence of epidermal growth factor receptor mutations and anaplastic lymphoma kinase fusions was 33.4% and 12%, respectively. Brain imaging leads to upstaging in 7% cases. The prevalence of brain metastases was 21% (n = 104), with half being asymptomatic (51%).
