Improving the timeliness and completion of vaccination is the key to reducing under-5 childhood mortality. This study examines the prevalence of delayed vaccination for doses administered at birth and age 6 weeks, 10 weeks, 14 weeks, and 9 months and its association with undervaccination among infants in Sub-Saharan Africa.

Pooling data across 33 Sub-Saharan Africa countries, vaccination timing and series completion were assessed for children aged 12-35 months who were included in the immunization module of the Demographic and Health Surveys conducted between 2010 and 2019. Survey design-adjusted logistic regression modeled the likelihood of not fully completing the basic immunization schedule associated with dose-specific delays in vaccination. Data were obtained and analyzed in May 2020.

Among children with complete date records (n=70,006), the proportion of children vaccinated with delays by ≥1 month was high 25.9% for Bacille Calmette-Guerin (at birth); 49.1% for the third dose of pentavalent combinch is sponsored by the Global Institute for Vaccine Equity at the University of Michigan School of Public Health.

Reference pricing establishes a set price a hospital is willing to pay for total knee arthroplasty (TKA) components regardless of vendor. The hospital contracts with vendors that sell implants to the hospital at the hospital-dictated prices. Orthopedic surgeons are free to utilize any implant system that has met the reference price using their best clinical judgment. Our hypothesis is that vendors will meet the set price and selection of different vendors and technologies will not change.

We retrospectively analyzed the 12 months prior (May 2017-2018) and the most recent 12 months after (March 2019-2020) implementing reference pricing at our institution. We investigated differences in average prices for total implant and component costs. We evaluated cost of implants with respect to surgeon volume, assessed the rate of cementless TKAs used, and number of companies purchased from before and after reference pricing.

In total, 7148 TKAs were included in the study with 3790 arthroplasties before and 3358 after implementation of reference pricing. Overall implant costs decreased by 16.7% (P < .0001). All individual knee component costs decreased by at least 11% (P= .0003). read more No difference in prices were found among surgeons (P= .9758). Cementless knee use increased by 9% (P < .0001; odds ratio 1.94, 95% confidence interval= 1.69-2.24). No vendor business was lost.

The strategy of reference pricing significantly reduced costs for TKA implants at our institution. The reduction in implant costs was regardless of surgeon volume. Newer technologies were utilized more often after reference pricing. This strategy represents a significant cost-savings approach for other hospitals.

To our knowledge, this is the largest single-center cohort of the 36-mm Corail-Pinnacle metal-on-metal total hip replacements system, aiming to determine 10-year survivorship and identify predictors of revision. We further assessed year of implantation given reports of manufacturing variations affecting shells made after 2006 predisposing these components to increasing wear.

All Corail-Pinnacle 36-mm metal-on-metal hips implanted in a single center (2005-2012). The effect of patient and implant-related variables, and year of implantation on revision risk was assessed using Kaplan-Meier, Cox regression, and interrupted time series analysis.

In total, 1212 metal-on-metal total hip replacements were implanted with a 10-year survival rate of 83.4% (95% confidence interval [CI]= 81.3-85.5). Mean follow-up duration was 7.3 years with 61% of patients reaching a minimum of 7 years of follow-up. One hundred nineteen patients required revision surgery (9.8%). Univariate analysis identified female gender (hazard r adverse reaction to metal debris. Female gender and high femoral offset stems were significant predictors for all-cause revision. Year of implantation was not significantly associated with an increasing number of revisions from 2007 onwards, although further studies to validate the impact of manufacturing discrepancies are recommended.

Despite the effectiveness of total knee arthroplasty (TKA), patients often have lingering pain and dysfunction. Recent studies have raised concerns that preoperative mental health may negatively affect outcomes after TKA. The primary aim of this study investigates the relationship between patient-reported mental health and postoperative physical function following TKA.

A retrospective study of 1392 primary TKA patients was performed. Mental health and physical function scores were measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health, and PROMIS Physical Function 10a and Knee injury and Osteoarthritis Outcome Score Physical Function (KOOS-PS) short forms. These assessments were completed preoperatively and up to 1-year postoperatively. Patients were stratified based on preoperative mental health scores into five distinct categories ranging from "Poor" to "Excellent." Locally estimated scatter plot smoothing curves (LOESS) were fit to the data examining physicalcal function scores may deteriorate a year after surgery. Tighter follow-up guidelines, more frequent physical therapy visits, or treatment for mental health issues may be considered to counter such deterioration.miRNAs inherently alter the cellular environment by regulating target genes. miRNAs may also regulate other miRNAs, with far-reaching influence on miRNA and mRNA expression. We explore this realm of small RNA regulation with a focus on the role of the oncogenic miR-21 and its impact on other miRNA species.

The oncological benefit of neoadjuvant chemotherapy (NAC) alone for locally advanced rectal cancer (LARC) remains controversial. The aim of this study was to clarify the clinical risk factors for poor prognosis before and after NAC for decision making regarding additional treatment in patients with LARC.

We examined a total of 96 patients with MRI-defined poor-risk locally advanced mid-low rectal cancer treated by NAC alone between 2006 and 2018. Survival outcomes and clinical risk factors for poor prognosis before and after NAC were analyzed.

In the median follow-up duration after surgery of 60 months (3-120), the rates of 5-year overall survival (OS), relapse-free survival (RFS), and local recurrence (LR) were 83.6%, 78.4%, and 8.2%, respectively. In the multivariate analyses, patients with cT4 disease had a significantly higher risk of poor OS (HR; 6.10, 95% CI; 1.32-28.15, P=0.021) than those with cT3 disease. After NAC, ycN+ was significantly associated with a higher risk of poor OS (HR; 5.92, 95% CI; 1.
