With the availability of multiple Coronavirus Disease 2019 (COVID-19) vaccines and the predicted shortages in supply for the near future, it is necessary to allocate vaccines in a manner that minimizes severe outcomes, particularly deaths. To date, vaccination strategies in the United States have focused on individual characteristics such as age and occupation. Here, we assess the utility of population-level health and socioeconomic indicators as additional criteria for geographical allocation of vaccines.

County-level estimates of 14 indicators associated with COVID-19 mortality were extracted from public data sources. Effect estimates of the individual indicators were calculated with univariate models. Presence of spatial autocorrelation was established using Moran's I statistic. Spatial simultaneous autoregressive (SAR) models that account for spatial autocorrelation in response and predictors were used to assess (i) the proportion of variance in county-level COVID-19 mortality that can explained by idtors.

Significant spatial autocorrelation exists in COVID-19 mortality in the US, and population health/socioeconomic indicators account for a considerable variability in county-level mortality. In the context of vaccine rollout in the US and globally, national and subnational estimates of burden of disease could inform optimal geographical allocation of vaccines.

Congenital internal small bowel hernias are rare and patients with them usually present with small bowel obstruction (SBO) at a young age, whereas in older patients, internal small bowel hernias usually are acquired secondary to previous surgery. The present report is of a rare case of SBO due to dual congenital internal small bowel hernias in a 51-year-old man with no history of abdominal surgery. Vismodegib CASE REPORT We report a case of dual congenital internal hernias of the small bowel in a patient who presented with symptoms and signs of SBO. He had no history of abdominal trauma, surgery, or comorbid conditions. His abdomen was mildly distended with minimal tenderness in the upper left quadrant but there was no guarding or rebound tenderness. Abdominal X-rays confirmed the SBO. A contrast-enhanced computed tomography scan of the patient's abdomen revealed SBO with transition at 2 points, suggestive of a closed-loop obstruction. However, the exact cause of the SBO was confirmed at laparotomy, which revealed dual internal hernias (intramesosigmoid and paraduodenal). The hernias were managed individually and the patient had a successful outcome after surgery. CONCLUSIONS Although the present report is of a rare presentation of internal small bowel hernia, the case underscores that patients with this condition may present with SBO. Successful surgical management requires knowledge of the intra-abdominal peritoneal spaces and management of the hernia sac.
The relationship between orthopaedic surgeons and the internet is complicated. Social media allows surgeons to educate their patients while marketing to them at the same time. Conversely, patients are able to better communicate with their surgeons while anonymously rating their service and expertise. This study aims to look at the complex relationship between surgeons and social media use.

To analyze the effect of fluid on visual acuity in cases of Type 3 macular neovascularization (MNV).

This multi-centric, retrospective cohort study included eyes with treatment-naïve Type 3 MNV. Analysis of fluid in different compartments was performed. Group A included eyes with isolated intraretinal fluid (IRF), while Group B included eyes with IRF in conjunction with sub retinal fluid (SRF) and/or sub retinal pigment epithelial fluid (Sub-RPEF).

Eyes in Group A (31, 55.3%) had better BCVA of 20/50 snellen equivalent (0.42 ± 0.31 logMAR) at baseline and 20/50 snellen equivalent (0.40 ±0.28 logMAR) at complete resolution compared to Group B with visual acuity of 20/80 snellen equivalent (0.64 ± 0.35 logMAR) (p= 0.0181) at baseline and 20/100 snellen equivalent (0.70 ± 0.40 logMAR) (p= 0.0021) at complete resolution. Subfoveal atrophy was more in Group B (82.6% 19/23) at complete resolution in comparison to Group A ((16/31, 51.6%). Eyes in Group B needed more anti-VEGF injections (10.3±9.0) for complete resolution compared to Group A (5.7±4.8).

IRF might be associated with good visual acuity in Type 3 MNV in contrast to other forms of n-AMD. Furthermore, IRF in isolation might need fewer injections and could probably be associated with less subfoveal atrophy.

Standard lead aprons and vests do not adequately shield the most common breast cancer site, the upper outer quadrant (UOQ), from intraoperative radiation. The purpose of the present study was to determine if lead sleeves, wings, and/or axillary supplements decreased intraoperative radiation exposure of the UOQ of the breast.

An anthropomorphic torso phantom (simulating the female surgeon) was placed adjacent to a standard operating room table. Dosimeters were placed bilaterally over the UOQ of the breast. Scatter radiation dose equivalent rates (mrem/hr) were measured during continuous fluoroscopy of a pelvic phantom (simulating the patient). Five protection configurations (no lead; lead vest; and vest with sleeves, wings, and axillary supplements), 2 surgeon positions (facing the table and perpendicular to the table), and 2 C-arm positions (anteroposterior and cross-table lateral projection) were tested. The t test was utilized with a Bonferroni correction for multiple t tests.

Lead sleeves and axillary supplements decreased intraoperative radiation exposure to the UOQ of the breast when compared with a well-fitted standard lead vest alone (p < 0.
