Persons receiving maintenance dialysis are at increased risk for SARS-CoV-2 infection and its severe outcomes, including death. However, rates of SARS-CoV-2 infection and COVID-19-related deaths in this population are not well described. Since November 2020, CDC's National Healthcare Safety Network (NHSN) has collected weekly data monitoring incidence of SARS-CoV-2 infections (defined as a positive SARS-CoV-2 test result) and COVID-19-related deaths (defined as the death of a patient who had not fully recovered from a SARS-CoV-2 infection) among maintenance dialysis patients. This analysis used NHSN dialysis facility COVID-19 data reported during June 30, 2021-September 27, 2022, to describe rates of SARS-CoV-2 infection and COVID-19-related death among maintenance dialysis patients. The overall infection rate was 30.47 per 10,000 patient-weeks (39.64 among unvaccinated patients and 27.24 among patients who had completed a primary COVID-19 vaccination series). The overall death rate was 1.74 per 10,000 patient-weeks. Implementing recommended infection control measures in dialysis facilities and ensuring patients and staff members are up to date with recommended COVID-19 vaccination is critical to limiting COVID-19-associated morbidity and mortality.

OBJECTIVES: Standardised reporting of patient and public involvement (PPI) in research studies is needed to facilitate learning about how to achieve effective PPI. The aim of this evaluation was to explore the impact of PPI in a large UK study, the Life After Prostate Cancer Diagnosis (LAPCD) study, and to explore the facilitators and challenges experienced. DESIGN: Mixed-methods study using an online survey and semistructured interviews. Survey and topic guide were informed by systematic review evidence of the impact of PPI and by realist evaluation. Descriptive analysis of survey data and thematic analysis of interview data were conducted. Results are reported using the GRIPP2 (Guidance for Reporting Involvement of Patients and the Public, Version 2) reporting guidelines. SETTING: LAPCD study, a UK-wide patient-reported outcome study. PARTICIPANTS: User Advisory Group (UAG) members (n=9) and researchers (n=29) from the LAPCD study. RESULTS: Impact was greatest on improving survey design and topic guides for interviews, enhancing clarity of patient-facing materials, informing best practices around data collection and ensuring steering group meetings were grounded in what is important to the patient. Further impacts included ensuring patient-focused dissemination of study findings at conference presentations and in lay summaries.Facilitating context factors included clear aims, time to contribute, confidence to contribute, and feeling valued and supported by researchers and other UAG members. Facilitating mechanisms included embedding the UAG within the study as a separate workstream, allocating time and resources to the UAG reflecting the value of input, and putting in place clear communication channels. Hindering factors included time commitment, geographical distance, and lack of standardised feedback mechanisms. CONCLUSION: Including PPI as an integral component of the LAPCD study and providing the right context and mechanisms for involving the UAG helped maximise the programme's effectiveness and impact.

ABSTRACT: Kunces, LJ, Keenan, J, Schmidt, CM, and Schmidt, MA. Molecular deficits relevant to concussion are prevalent in top-ranked football players entering the National Football League draft. J Strength Cond Res 35(11): 3139-3144, 2021-Characterization of blood variants in athletes entering the highly competitive contact environment of professional football can help us understand the risk for brain injury. When coupled with longitudinal follow-up of future concussion incidence and trajectory, it may provide additional insight into factors that influence brain injury. We observed the metabolic phenotype of collegiate football players entering the 2016 National Football League (NFL) draft. The principal aims were to characterize the molecular status of individual athletes and quantify the prevalence of athletes with multiple concurrent molecular deficits. Blood was taken from 30 elite American collegiate football players 7 weeks before the NFL scouting combine and 15 weeks before entering the NFL draft. Average results revealed suboptimal values in Omega-3 Index (avg ± std, 4.66 ± 1.16%), arachidonic acid:eicosapentaenoic acid fatty acid ratio (29.13 ± 10.78), homocysteine (11.4 ± 3.4 µmol·L-1), vitamin D (30 ± 11.4 ng·ml-1), and red blood cell magnesium (4.1 ± 0.8 mg·dl-1). Using sport-optimized reference ranges from previously published research, 10% presented with 3, 40% presented with 4, and 50% of athletes presented with 5 suboptimal values at once. We conclude molecular deficits in this cohort entering the NFL draft were common, with a significant number of athletes presenting with multiple suboptimal levels. The significant commonality of the suboptimal biomarkers is relevance to brain health and function. This data warrant extensive metabolic phenotyping and consideration of prophylactic precision nutrition countermeasures by the multidisciplinary staff for athletes entering contact environments.

Background: The optimal approach to conducting antibiotic stewardship interventions has not been defined. We compared days of antibiotic therapy (DOT) using preprescription authorization (PPA) vs postprescription review with feedback (PPRF) strategies. Methods: A quasi-experimental, crossover trial comparing PPA and PPRF for adult inpatients prescribed any antibiotic was conducted. For the first 4 months, 2 medicine teams were assigned to the PPA arm and the other 2 teams to the PPRF arm. The teams were then assigned to the alternate arm for an additional 4 months. Appropriateness of antibiotic use was adjudicated by at least 2 infectious diseases-trained clinicians and according to institutional guidelines. Results: There were 2686 and 2693 patients admitted to the PPA and PPRF groups, with 29% and 27% of patients prescribed antibiotics, respectively. Initially, antibiotic DOTs remained relatively unchanged in the PPA arm. When changed to the PPRF arm, antibiotic use decreased (-2.45 DOT per 1000 patient-days [PD]). In the initial PPRF arm, antibiotic use decreased (slope of -5.73 DOT per 1000 PD) but remained constant when changed to the PPA arm. Median patient DOTs in the PPA and PPRF arms were 8 and 6 DOT per 1000 PD, respectively (P = .03). Antibiotic therapy was guideline-noncompliant in 34% and 41% of patients on days 1 and 3 in the PPA group (P < .01) and in 57% and 36% of patients on days 1 and 3 in the PPRF group (P = .03). Conclusions: PPRF may have more of an impact on decreasing antibiotic DOTs compared with PPA. This information may be useful for institutions without sufficient resources to incorporate both stewardship approaches.

INTRODUCTION: Nerve injuries can occur from major hip surgeries, and some may be significant. Our goal was to assess the feasibility and safety of neuromonitoring during hip preservation surgery and the incidence of alerting events during such monitoring. METHODS: Twenty-five adult patients underwent surgical hip dislocation for femoroacetabular impingement. Upper and lower extremity somatosensory evoked potentials, lower extremity transcranial motor evoked potentials, and lower extremity electromyography were recorded. RESULTS: We observed a temporary reduction of the monitored parameters in twelve patients (48%) during surgery. There were no clinically significant neurological deficits postoperatively in any cases. DISCUSSION: Neuromonitoring did demonstrate events during hip surgery in our case series. Although it may not be practical to use neuromonitoring in all major hip surgeries, it may be prudent from the perspective of patient safety to use it in high-risk cases, including those requiring prolonged surgical time; in patients with high body mass index, excessive deformity correction, and preexisting neuropathy; and in revision cases, among others.
ABSTRACT
BACKGROUND: Iron supplementation is recommended for pregnant women to meet their iron requirement for a healthy pregnancy. The benefits and risks of universal iron supplementation during pregnancy in malaria endemic countries are currently being debated. As part of a broader study that focused on the effect of heme/HO-1 on pregnancy outcomes in malaria in pregnancy, we determined the association between iron supplementation and free heme levels in blood of pregnant women with and without malaria in Ghana. We hypothesized that pregnant women with malaria who took iron supplements will have higher levels of Heme/HO-1 than those who did not take iron supplements. METHODS: A total of 337 women were recruited for this study. Blood samples were collected for malaria diagnosis and heme/HO-1 measurement. Quantification of heme was done using a heme colorimetric assay kit and HO-1 levels were performed using Enzyme-Linked Immunosorbent Assay (ELISA) on plasma samples. RESULTS: Malaria positive iron supplemented women, in their third trimester, had significantly higher median levels of heme 59.3(43.1 - 60.4) than non-malaria iron supplemented women 35.7(33.0 - 62.2), p = 0.026. Also, malaria positive iron supplemented women had significant higher median levels of HO-16.2(IQR 4.9 - 8.1) than pregnant women who did not take iron supplements 2.9 (IQR 2.1 - 3.8), p = <0.001. CONCLUSION: Although iron supplementation may be highly beneficial and improve pregnancy outcomes for iron deficient or anemic mothers, it is also likely that iron supplementation for pregnant women who are not iron deficient may put this group of women at risk for adverse pregnancy outcomes. Findings from this study sheds light on the effect of iron supplementation on malaria derived heme in pregnancy, which may inform how iron supplementation is recommended for pregnant women who are not iron deficient.
ABSTRACT
A case-control study was conducted to determine the association between maternal height and infant length-for-age, and to evaluate how this association is modified by either maternal or infant nutritional status. We hypothesised that maternal excess caloric intake [measured as body mass index (BMI)] would increase the association, while infant nutrition (measured in main meals consumed in addition to breastfeeding) will diminish the effect. Mother and infant pairs in Chimaltenango, Guatemala, were measured for anthropometric values and nutritional status, and mothers were interviewed to elicit nutritional and socio-economic information. Infant length was converted into z-scores based on the World Health Organization's (WHO) standards. Odds ratios (ORs), associated 95% confidence intervals (CIs) and the relative excess risk due to interaction (RERI) were calculated. Cases were infants below 2 z-scores of the WHO's length-for-age, while controls were infants within the -2 to 2 z-score range. Cases (n = 84) had an increased odds (OR: 3.00, 95% CI: 1.57-5.74) of being born to a stunted mother (below 145 cm) when compared with controls (n = 85). When adjusted for potential confounders, the OR decreased to 2.55 (95% CI: 1.30-5.02). Negative RERI values were produced for the joint exposure of maternal BMI ≥ 25 and maternal stuntedness (RERI: -0.96), as well as for the joint exposure of maternal stuntedness and infant nutrition (RERI: -2.27). Our results confirm that maternal stuntedness is a significant contributor to infant stuntedness; however, this association is modified negligibly by maternal nutritional status and significantly by infant nutritional status, each in a protective manner.

OBJECTIVE: To explore the relationship between age-related macular degeneration (AMD) and hypothyroidism in a population-based sample of adults 50 years and older in the United States. STUDY POPULATION: Participants aged 50 years and older (N = 9,677). Of this total, 356 participants reported having AMD and 9321 reported not having AMD. METHODS: Information pertaining to self-reported thyroid disease (specifically hypothyroidism) and AMD was obtained from the 2008 National Health Interview Survey. The association between self-reported data on hypothyroidism and AMD was estimated using logistic regression adjusting for the potentially confounding influence of demographic, behavioral, and health-related characteristics. RESULTS: Of the 356 people with AMD, 20.9% reported hypothyroidism compared to 11.2% of those 9,321 without AMD (odds ratio [OR] 2.33; 95% confidence interval [CI] 1.69-3.21). After adjusting for the confounding influence of age, sex, smoking, and race, the association between AMD and hypothyroidism remained significant (OR 1.59; 95% CI 1.10-2.30). CONCLUSIONS: The results of this study add to the small body of literature indicating a possible relationship between AMD and hypothyroidism. As many of the risk factors for AMD are also risk factors for hypothyroidism, future studies are warranted to ascertain the relationship between the two diseases.

BACKGROUND: Aflatoxin exposure has been shown to cause cell-mediated immune suppression and enhance HIV viral replication. Such immune suppression from aflatoxin can impair resistance to both infectious diseases and chronic infections. METHODS: Hazard ratios (HRs) with 95% confidence intervals (CI) and a test for trend for opportunistic infections OI) among 141 HIV positive Ghanaians based on quartiles of aflatoxin B1 albumin adduct levels (AF-ALB) were calculated. FINDINGS: HRs were significantly higher for developing symptomatic TB (HR 3.30, 95% CI 1.34-8.11) for those in the highest AF-ALB quartile compared to the lowest. Significantly higher HRs were not observed for other infections investigated. CONCLUSIONS: Those with the highest levels AF-ALB from dietary intake have an increased hazard of symptomatic TB but not malaria, HBV, or pneumonia.
ABSTRACT
A retrospective, matched case-control study was conducted in Jamaica's Western Regional Health Authority (WRHA). Forty-three individuals developing clinical leptospirosis between January 2005 and December 2007 (i.e., cases) were age and neighborhood matched to 89 controls. Odds ratios (OR) and associated 95% confidence intervals (CIs) and the relative excess risk due to interaction (RERI) were calculated. Cases had increased odds of contact with rodents OR 3.52, goats OR 3.38, and being engaged in outdoor labor OR 5.30. Knowledge of leptospirosis and indoor work was protective, OR 0.39 and OR 0.16, respectively. Positive RERI values were noted for joint exposure to rodents and goats (RERI 5.54), outdoor labor and goats (RERI 6.97), and outdoor labor and rodents (RERI 30.59). Our results suggest a synergistic effect of occupational and environmental exposures on clinical human leptospirosis from the WRHA. Knowledge of the disease and its risk factors allows for protection from the disease.

Intravenous regional anesthesia (IVRA) is a well-recognized technique for producing anesthesia during surgical procedures of the extremities. It has been suggested that the application of a tourniquet to the forearm may improve the quality of the block. The purpose of this investigation was to determine whether the application of a forearm tourniquet would accelerate onset time and improve the density and quality of an intravenous regional block. Twenty volunteer subjects were enrolled and randomly assigned in this crossover investigation. Control subjects received a standard IVRA technique; experimental subjects received IVRA technique with the application of a simple forearm tourniquet. Pain was elicited by means of an electrical stimulus, and assessments were performed using a 100-mm Visual Analogue Scale (VAS). Paired t tests were used to examine differences between groups on the variables studied. It was noted that the arm with the tourniquet had a shorter time for the onset of anesthesia (P = .0008) and had lower 10-minute VAS tolerance (P = .0469). This investigation suggests that the application of a simple forearm tourniquet as an adjunct to IVRA provides a more rapid onset of anesthesia than when no tourniquet is applied and may improve the density and quality of the block.
