The COVID-19 pandemic continues to devastate countries around the world. Pakistan has had a largely successful control strategy with fewer hospitalizations and mortality than its neighboring countries of China, Iran, and India. The aim of our study was to assess Pakistan's state of preparedness for and response to the COVID-19 outbreak, including its multifaceted approach in surveillance, response, and diagnostic services. The study was a situational analysis based on the 2020 World Health Organization COVID-19 Strategic Preparedness and Response Plan. The authors collected national data from January to August 2020 from the government of Pakistan's COVID-19 website and Pakistan's Directorate of Central Health Establishments. We also conducted an extensive review of recently published articles on COVID-19, literature, news alerts, and publicly available data on COVID-19 in Pakistan. Selleckchem Merestinib To address the COVID-19 pandemic, the country drafted a national action plan, developed mobile applications and the national 1166 helpline, conducted thermal screening and active case finding at all points of entry, and established and strengthened a surveillance system for contact tracing and case-based surveillance, with coordination at the federal and provincial levels. Additionally, a total of 134 laboratories have been designated in major cities for testing of COVID-19; 735 hospitals have been designated for the management of cases in isolation wards at federal, provincial, and regional levels; and dedicated quarantine places have been ensured. Despite being a resource-constrained country, the government of Pakistan has mounted a coordinated national effort using the best available resources. The government is rightly focusing on 4 major areas-surveillance, management, response, and coordination-in controlling the COVID-19 pandemic in Pakistan.Exposure to stigma, violence, sex work, and substance use are associated with increased HIV risk, but relationships between these factors have not been fully elucidated among transgender women whose data are often aggregated with men who have sex with men and other sexual and gender minorities. Considering this gap, we aimed to identify a serologically confirmed HIV estimate for transgender women and examine the relationships between stigma, sex work, substance use, and HIV among a national sample of transgender women in Dominican Republic. We analyzed biomarkers and self-report data from the third wave of Dominican Republic's Encuesta de Vigilancia y Comportamiento con Vinculación Serológica, employing logistic and negative binomial regression to estimate models (n = 307). HIV rate was 35.8%. Nearly 75% of respondents engaged in sex work. Over 20% reported experiencing violence; 61.6% reported being stigmatized. Participation in sex work was associated with higher levels of stigma [incidence rate ratio (IRR) 1.70, p  less then  0.05]. Respondents who experienced violence had over three times higher odds of living with HIV relative to respondents who had not been victimized [odds ratio (OR) 3.15, p  less then  0.05]. link2 Marijuana users were less likely to experience stigma compared with cocaine users (IRR 1.72, p  less then  0.05), and a higher risk of alcohol dependency was associated with higher odds of experiencing violence (OR 1.17, p  less then  0.001). Findings illustrate the importance of disaggregating data collected from transgender women compared with other sexual and gender minorities to ascertain subpopulation-specific estimates and indicate an urgent need to implement structural interventions and policies to protect transgender women's health and their human rights.

The purpose of our work is to assess the role of tumor-to-normal tissue (T/N) dosimetry ratios for predicting response in patients undergoing locoregional therapy to the liver with

Y microspheres.

39 patients (seven femal32 male, mean age 68.3 ± 7.6y), underwent PET/CT imaging after treatment with

Y microspheres. For attenuation correction and localization of the

Y microspheres, the low dose, non-diagnostic CT images from PET/CT were used. The acquisition took 15 min and the reconstruction matrix size was 200 × 200×75 mm and voxel size of 4.07 × 4.07×3.00 mm. For dosimetry calculations the local deposition method with known activity of

Y was used. For each patient, regions-of-interest (ROIs) for tumor(s) and whole liver were manually created; the normal tissue ROI was created automatically. mRECIST criteria on MRI done at a month post treatment and subsequently every three months after

Y treatment, were used to assess response.

For 39 patients, the mean liver, tumor and normal tissue doses (mean ± SD) were, 55.17 ± 26.04 Gy, 911.87 ± 866.54 Gy and 47.79 ± 20.47 Gy respectively. Among these patients, 31 (79%) showed complete response (CR) and 8 (21%) showed progression of disease (PD). For patients with CR, the mean T/N dose ratio obtained was 24.91 (range 3.09-80.12) and for patients with PD, the mean T/N dose ratio was significantly lower, at 6.69 (range 0.36-14.75).

Our data shows that patients with CR have a statistically higher T/N dose ratio than those with PD. Because, the number of PD cases was limited and partial volume effect was not considered, further investigation is warranted.

Tumor-to-normal tissue dosimetry ratios can be used for assessing response in patients undergoing locoregional therapy to the liver with

Y microspheres.

Tumor-to-normal tissue dosimetry ratios can be used for assessing response in patients undergoing locoregional therapy to the liver with 90Y microspheres.Background Many heart diseases can develop a reduced pumping capacity of the heart muscle. A mismatch between ATP demand and ATP production of cardiomyocytes is one of the possible causes. Assessment of the relation between the myocardial ATP production (MVATP) and cardiac workload is important for better understanding disease development and choice of nutritional or pharmacological treatment strategies. As there is currently no method for the measurement of MVATP in vivo, the use of physiology-based metabolic models in conjunction with protein abundance data is an attractive approach. Methods We developed a comprehensive kinetic model of the cardiac energy metabolism (CARDIOKIN1), which recapitulates numerous experimental findings on cardiac metabolism obtained with isolated cardiomyocytes, perfused animal hearts and in vivo studies with humans. We used the model to assess the energy status of the left ventricle (LV) of healthy subjects and patients with aortic stenosis (AS) and mitral valve insufficiency (M valvular dysfunction is generally diminished and correlates positively with mechanic energy demand and cardiac output. However, large differences exist in the energetic state of the myocardium even in patients with similar clinical or image-based markers of hypertrophy and pump function.

Ultrasound emerges as a complement to cone-beam computed tomography in dentistry, but struggles with artifacts like reverberation and shadowing. This study seeks to help novice users recognize soft tissue, bone, and crown of a dental sonogram, and automate soft tissue height (STH) measurement using deep learning.

In this retrospective study, 627 frames from 111 independent cine loops of mandibular and maxillary premolar and incisors collected from our porcine model (

= 8) were labeled by a reader. 274 premolar sonograms, including data augmentation, were used to train a multi class segmentation model. The model was evaluated against several test sets, including premolar of the same breed (

= 74, Yucatan) and premolar of a different breed (

= 120, Sinclair). We further proposed a rule-based algorithm to automate STH measurements using predicted segmentation masks.

The model reached a Dice similarity coefficient of 90.7±4.39%, 89.4±4.63%, and 83.7±10.5% for soft tissue, bone, and crown segmentation, respectively on the first test set (

= 74), and 90.0±7.16%, 78.6±13.2%, and 62.6±17.7% on the second test set (

= 120). The automated STH measurements have a mean difference (95% confidence interval) of -0.22 mm (-1.4, 0.95), a limit of agreement of 1.2 mm, and a minimum ICC of 0.915 (0.857, 0.948) when compared to expert annotation.

This work demonstrates the potential use of deep learning in identifying periodontal structures on sonograms and obtaining diagnostic periodontal dimensions.

In adolescents with severe obesity, little is known about how adolescent/mother dyads approach management. Our study aims to (1) explore similarities/differences in adolescent/mother dyads' perceptions of weight management behaviors and (2) describe their experiences with successes and challenges related to weight management. Methods This was a qualitative descriptive analysis of interviews from 21 adolescent/mother dyads. Conventional content analysis was used to identify themes characterizing dyads' weight management efforts. Results Two patterns of perceptions were identified across the dyads specific to weight management behaviors collaborative (dyads agreed) and conflicting (dyads disagreed). link3 Weight management themes with collaborative perceptions were food preferences; food and emotion; the adolescent is active; exercise is not enjoyable; the family is active together; and stopping medications. Weight management themes with conflicting perceptions were responsibility for initiating and maintaining exercise, motivation and willingness to exercise, and responsibility for medications. Dyads had collaborative pattern responses on perceptions of success and challenges. Themes related to successes were weight loss and supportive relationships. Themes related to challenges were inconsistent daily routines and schedules, and unsupportive relationships. Conclusions Dyads responded with collaborative or conflicting perceptions to weight management behaviors and with collaborative responses to success and challenges. Sustaining healthy habits was difficult from the perspectives of dyads. For youth with severe obesity, providing care that recognizes and addressees issues youth and their families experience may require improved and innovative interventions.Background Studies of transgender/gender diverse (TGD) youth indicate a high prevalence of overweight/obesity and concern for unhealthy weight management behavior. This study describes the association of weight status with medication use and recreational activities among treatment-naïve, pediatric TGD patients. Methods This study is a chart review of 277 patients [aged 9-18 years, 79.1% female sex assigned at birth (SAB), and 86.3% white] seen at a medical center from 2017 to 2020. BMI was calculated by age and SAB using CDC growth charts. BMI percentile (BMI%) and BMI z-score (BMIz) were used to define weight status. Results By BMI% category, 3.6% patients were in the underweight range (BMI 95%. Overweight and obesity rates were higher than national norms (χ2 = 15.152, p  less then  0.01). Female SAB participants had higher BMIz values than male SAB participants. Youth who reported watching/listening to media (t = 3.50, p  less then  0.01) and parent-reported creative arts involvement (t = 1.97, p = 0.05) were associated with higher BMIz values.
