Prenatal exposure to alcohol can cause lifelong physical and cognitive challenges in the form of fetal alcohol syndrome and other fetal alcohol spectrum disorders (FASDs). The prevention of prenatal alcohol exposure is thus a public health priority - and one that should account for the particular needs of subpopulations, including in American Indian/Alaska Native (AI/AN) communities. Prior to conception, alcohol-exposed pregnancy prevention is accomplished by encouraging the reduction or elimination of risky alcohol use and/or promoting effective contraceptive use among risky drinkers who could become pregnant. The current study builds on promising findings about the impact of the Centers for Disease Control and Prevention CHOICES intervention with AI/AN communities by implementing a randomized control trial of Native CHOICES, a cultural adaptation of CHOICES, with AI/AN women in a rural reservation community.

AI/AN women aged 18-44 who are at-risk for an alcohol-exposed pregnancy are being recruited. Par CHOICES intervention consists of 2 motivational interviewing (MI) sessions, an elective contraception counseling session, and electronic messaging to boost the effects of MI. Data are collected at baseline and at 6 weeks, 3 months, and 6 months post-baseline. Those assigned to the control group are eligible to enroll in Native CHOICES following the completion of the 6 months post-baseline data collection. In addition to testing intervention effectiveness, the study is designed to yield a comprehensive economic evaluation, which will provide important information regarding the financial feasibility and sustainability of Native CHOICES for healthcare systems serving AI/ANs.
The aim of the present study was to examine the relationship between the great saphenous vein (GSV) length of segment ablated and diameter with symptom improvement.

Data from a multicenter, randomized, controlled prospective study of 242 patients undergoing radiofrequency ablation (RFA) or cyanoacrylate closure (CAC) of the GSV were analyzed. The venous clinical severity score (VCSS) was measured at baseline and at 1, 3, 6, 12, 24, and 36months after ablation. The GSV diameter was evaluated for a correlation with VCSS at each time point. Using the median treatment length of 34cm, the patients were divided into group I (treatment length ≥34cm) vs group II (<34cm) for analysis. The pretreatment VCSS and VCSS improvement (ΔVCSS) after treatment were evaluated with respect to the length of the ablated GSV segment. The postablation VCSS was compared between the pretreatment GSV diameters of<5.5mm vs ≥5.5mm.

The mean GSV length ablated by RFA was 35.3± 14cm vs 32.6± 11cm with CAC (P= NS). No significantverity. We found a small to moderate correlation between the length of GSV segment ablated and symptom improvement. This might reflect the greater severity of symptoms at baseline in patients with longer segments with reflux. We found a poor correlation between the proximal GSV diameter and symptom improvement after ablation.
Longer segments of GSV reflux appeared to correlate with symptom severity. We found a small to moderate correlation between the length of GSV segment ablated and symptom improvement. This might reflect the greater severity of symptoms at baseline in patients with longer segments with reflux.

Compared to women with a live birth, women with a stillbirth are more likely to have maternal complications during pregnancy and at birth, but risk factors related to their postpartum health are uncertain.

This study aimed to identify patient-level risk factors for postpartum hospital readmission among women after having a stillbirth.

This was a population-based cohort study of 29,654 women with a stillbirth in California from 1997 to 2011. Using logistic regression models, we examined the association of maternal patient-level factors with postpartum readmission among women after a stillbirth within 6 weeks of hospital discharge and between 6 weeks and 9 months after delivery.

Within 6 weeks after a stillbirth, 642 women (2.2%) had a postpartum readmission. Risk factors for postpartum readmission after a stillbirth were severe maternal morbidity excluding transfusion (adjusted odds ratio, 3.02; 95% confidence interval, 2.28-4.00), transfusion at delivery but no other indication of severe maternal morb risk factors were largely similar to those for earlier readmission.

Women with comorbidities, with birth-related complications, of non-Hispanic black race and ethnicity, or with less education had increased odds of postpartum readmission after having a stillbirth, highlighting the importance of continued care for these women after discharge from the hospital.

Persistent occiput posterior and occiput transverse positions are associated with adverse maternal and neonatal outcomes. The objective of this study was to assess if the use of hands-and-knees posturing increased the rate of occiput anterior position immediately after posturing during the second stage of labor or at the time of birth.

An electronic search of PubMed, EMBASE, Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials was performed from inception to September 2020.

Eligibility criteriaincluded all randomized controlled trials of singleton gestations at ≥36 weeks' gestation that were randomized to either the hands-and-knees posture group or control group.The primary outcome was a composite of occiput anterior positioning during the second stage of labor or at birth. Individual components of the composite were assessed as secondary outcomes. Additional secondary outcomes were a change to occiput anterior position immediately after the intervention, use of regional anesthesia, duis of patients with an ultrasound-diagnosed malposition before posturing, there was a higher rate of occiput anterior positioning immediately after the intervention (17.0% vs 10.3%; relative risk, 1.63; 95% confidence interval, 1.06-2.52), but this relationship did not persist at delivery. The remainder of the subgroup analyses and secondary outcomes were insignificant.

Adopting a hands-and-knees posture does not increase the rate of occiput anterior positioning at time of delivery.

The impact of hormone replacement therapy (HRT) on clinical outcomes in menopausal women is uncertain.

To investigate the association between use of HRT and severe asthma exacerbation in perimenopausal and postmenopausal women with asthma.

We used the Optimum Patient Care Research Database, a population-based longitudinal primary care database in the United Kingdom, to construct a 17-year (January 1, 2000, to December 31, 2016) cohort of perimenopausal and postmenopausal (46-70 years, N= 31,656) women. We defined use of HRT, its subtypes, and duration of HRT use. Severe asthma exacerbation was defined as an asthma-related hospitalization, emergency department visits due to asthma, and/or prescription of oral corticosteroids. Analyses were undertaken using multilevel mixed-effects Poisson regression.

At baseline, 22% of women were using any HRT, 11% combined HRT, and 11% estrogen-only HRT. Previous, but not current, use of any (incidence rate ratio [IRR] 1.24, 95% confidence interval [CI] 1.22-1.26), costmenopausal women with established asthma. Lean women and smokers are at greater risk than heavier women and nonsmokers, respectively.Half-scan image reconstruction with Parker weighting can correct motion artifacts in dental CT images taken with a slow scan-based dental CT. Since the residual half-scan artifacts in the dental CT images appear much stronger than those in medical CT images, the artifacts often persist to the extent that they compromise the surface-rendered bone and tooth images computed from the dental CT images. We used a variation of generative adversarial network (GAN), so-called U-WGAN, to correct half-scan artifacts in dental CT images. For the generative network of GAN, we used a U-net structure of five stages to take advantage of its high computational efficiency. We trained the network using the Wasserstein loss function on the dental CT images of 40 patients. We tested the network with comparing its output images to the half-scan images corrected with other methods; Parker weighting and the other two popular GANs, that is, SRGAN and m-WGAN. For the quantitative comparison, we used the image quality metrics measuring the similarity of the corrected images to the full-scan images (reference images) and the noise level on the corrected images. We also compared the visual quality of the surface-rendered bone and tooth images. We observed that the proposed network outperformed Parker weighting and other GANs in all the image quality metrics. The computation time for the proposed network to process 336×336×336 3D images on a GPU-equipped personal computer was about 3 s, which was much shorter than those of SRGAN and m-WGAN, 50 s and 54 s, respectively.
Clinical notes are ubiquitous resources offering potential value in optimizing critical care via data mining technologies.

To determine the predictive value of clinical notes as prognostic markers of 1-year all-cause mortality among people with diabetes following critical care.

Mortality of diabetes patients were predicted using three cohorts of clinical text in a critical care database, written by physicians (n=45253), nurses (159027), and both (n=204280). Natural language processing was used to pre-process text documents and LASSO-regularized logistic regression models were trained and tested. Confusion matrix metrics of each model were calculated and AUROC estimates between models were compared. All predictive words and corresponding coefficients were extracted. Outcome probability associated with each text document was estimated.

Models built on clinical text of physicians, nurses, and the combined cohort predicted mortality with AUROC of 0.996, 0.893, and 0.922, respectively. Predictive performansk estimates of prognostic outcomes such as mortality could be used to optimize patient care.Coronavirus disease (COVID-19) rapidly expands to a global pandemic and its impact on public health varies from country to country. It is caused by a new virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is imperative for relapsing current antiviral therapeutics owing to randomized genetic drift in global SARS-CoV-2 isolates. A molecular mechanism behind the emerging genomic variants is not yet understood for the prioritization of selective antivirals. The present computational study was aimed to repurpose existing antivirals for Indian SARS-CoV-2 isolates by uncovering a hijack mechanism based on structural and functional characteristics of protein variants. Forty-one protein mutations were identified in 12 Indian SARS-CoV-2 isolates by analysis of genome variations across 460 genome sequences obtained from 30 geographic sites in India. Two unique mutations such as W6152R and N5928H found in exonuclease of Surat (GBRC275b) and Gandhinagar (GBRC239) isolates. Selleck Solcitinib We report for the first time the impact of folding rate on stabilizing/retaining a sequence-structure-function-virulence link of emerging protein variants leading to accommodate hijack ability from current antivirals.
