Identification and Validation of Nutrient State-Dependent Serum Protein Mediators of Human CD4+ T Cell Responsiveness

Intermittent fasting and fasting mimetic diets ameliorate inflammation. Similarly, serum extracted from fasted healthy and asthmatic subjects’ blunt inflammation in vitro, implicating serum components in this immunomodulation. To identify the proteins orchestrating these effects, SOMAScan technology was employed to evaluate serum protein levels in healthy subjects following an overnight, 24-h fast and 3 h after refeeding. Partial least square discriminant analysis identified several serum proteins as potential candidates to confer feeding status immunomodulation. The characterization of recombinant IGFBP1 (elevated following 24 h of fasting) and PYY (elevated following refeeding) in primary human CD4⁺ T cells found that they blunted and induced immune activation, respectively. Furthermore, integrated univariate serum protein analysis compared to RNA-seq analysis from peripheral blood mononuclear cells identified the induction of IL1RL1 and MFGE8 levels in refeeding compared to the 24-h fasting in the same study. Subsequent quantitation of these candidate proteins in lean versus obese individuals identified an inverse regulation of serum levels in the fasted subjects compared to the obese subjects. In parallel, IL1RL1 and MFGE8 supplementation promoted increased CD4⁺ T responsiveness to T cell receptor activation. Together, these data show that caloric load-linked conditions evoke serological protein changes, which in turn confer biological effects on circulating CD4⁺ T cell immune responsiveness.     

Effects of Coronavirus Disease Pandemic on Tuberculosis Notifications,Malawi

The coronavirus disease (COVID-19) pandemic might affect tuberculosis (TB) diagnosis and patient care. We analyzed a citywide electronic TB register in Blantyre, Malawi and interviewed TB officers. Malawi did not have an official COVID-19 lockdown but closed schools and borders on March 23, 2020. In an interrupted time series analysis, we noted an immediate 35.9% reduction in TB notifications in April 2020; notifications recovered to near prepandemic numbers by December 2020. However, 333 fewer cumulative TB notifications were received than anticipated. Women and girls were affected more (30.7% fewer cases) than men and boys (20.9% fewer cases). Fear of COVID-19 infection, temporary facility closures, inadequate personal protective equipment, and COVID-19 stigma because of similar symptoms to TB were mentioned as reasons for fewer people being diagnosed with TB. Public health measures could benefit control of both TB and COVID-19, but only if TB diagnostic services remain accessible and are considered safe to attend.

Management of Chronic Pain in Nursing Homes: Navigating Challenges to Improve Person-Centered Care

Despite the dynamic demands in the nursing home (NH), a definitive approach to managing chronic pain in older adults has yet to be established. Due to concerns for potential adverse pharmacologic effects, balancing appropriate pain management is a challenge among NH residents. The challenges encompass but are not limited to medical complexities, functional disabilities, and physical frailty. Barriers to the successful implementation of a comprehensive chronic pain management at the NH may include ambiguous directions on specific therapeutic interventions, insufficient guidance on treatment duration, and limited available treatment options. The Centers for Medicare and Medicaid Services’ reporting requirement of adequate pain control among NH residents coupled with widely variable clinician-prescribing habits highlights the difficulties in overcoming the preceding challenges and barriers. The Coronavirus Disease 2019 (COVID-19) pandemic has further complicated pain management due to its negative consequences on well-being of residents of NHs. Associated symptoms of psychosocial stress, anxiety and depression, and chronic pain symptoms can exacerbate during the COVID-19 pandemic, leading to increased requirement for pain medications including but not limited to opioids.Pain is a multidimensional symptom and requires a strategic multimodal approach for its management. Nonpharmacologic modalities are underutilized in the NH setting and are the preferred first steps for mild pain, and nonopioid pharmacological agents can be added as a second step for a synergistic effect for moderate to severe pain. Opioids should be used as a last resort. Short-acting opioids are preferred over extended-release/long-acting opioids for chronic pain. Clinicians are encouraged to engage residents in proactive strategies in managing their pain, and to set realistic expectations toward improving their quality of life, as complete elimination of pain is not feasible in most cases.This review article provides the interdisciplinary team with a contemporary perspective of the multitude of changes and challenges influencing the prescribing as well as deprescribing of various pain medications.     

Psychological Distress in Women Living with Polycystic Ovary Syndrome: The Role of Illness Perceptions

IntroductionPolycystic ovary syndrome (PCOS) is an endocrine and metabolic condition linked to increased risk of anxiety and depression (psychological distress). This study examined the relationship between illness perceptions and psychological distress in women living with PCOS.MethodsWe used a cross-sectional survey to assess psychological distress (Hospital Anxiety and Depression Scale) and illness perceptions (Illness Perception Questionnaire-Revised) in women living with PCOS in the UK (N = 487). Hierarchical multiple linear regression tested the associations between illness perceptions and psychological distress, adjusting for age, years since PCOS diagnosis, education, body mass index, current depression, and current anxiety disorder.ResultsIn the fully adjusted regression model, illness perceptions explained 18.6% of the variance in psychological distress, F(7,458) = 21.0, p < .001. Reporting more symptoms (B = 0.226), higher perceived consequences (B = 0.204), lower personal control (B = –0.184), and lower illness coherence (B = –0.127) were significantly associated with higher psychological distress (all p < .001).ConclusionsIllness perceptions may play an important role in psychological distress, even after adjusting for relevant demographics and clinical characteristics. Our findings highlight key areas where researchers and clinicians could develop targeted self-management interventions for women with PCOS, focused on altering maladaptive illness perceptions to reduce psychological burden.     

Contraceptive Method Uptake at Title X Health Centers in Utah

BackgroundThe Title X family planning program previously supported contraception for Utah clients with low incomes, yet its contributions may not have been sufficient to allow clients to select their preferred methods, including long-acting reversible contraceptives (LARCs). In this study, we compare the contraceptive method choices of self-paying clients with low incomes at three participating Title X health centers in Salt Lake County, Utah, before and after the removal of additional cost barriers.MethodsWe used retrospective medical record review to assess clients’ contraceptive choices during two 6-month periods: a control period with Title X-assisted sliding scale payment schedules (n = 2,776) and an intervention period offering no-cost contraceptive care (n = 2,065). We used logistic regression to identify the likelihood of selecting a LARC during the intervention period and multinomial regression to identify the selection probability of different types of available LARCs.ResultsDuring the control period, 16% of participants chose a LARC compared with 26% in the intervention period (p ≤ .001). During the intervention period, participants were 1.8 times more likely to select LARCs (95% confidence interval, 1.65–2.13) compared with non-LARC methods, holding covariates constant. In the multinomial regression, participants were three times more likely during the intervention period to select an implant than a pill, patch, or ring, holding all other covariates constant (odds ratio, 3.08; 95% confidence interval, 2.47–3.83).ConclusionsTitle X clients offered contraceptive methods without cost more frequently selected a LARC method. Title X funding reductions may impede individuals’ access to their contraceptive methods of choice.     

Direct comparison of reproducibility and reliability in quantitative assessments of burn scar properties

IntroductionDetermining the efficacy of anti-scar technologies can be difficult as qualitative, subjective assessments are often utilized instead of systematic, objective measures. Perceptions regarding the reliability of instruments for quantitative measurements along with their high cost and increased data collection time may discourage their use, leading to use of scar scales which are relatively quick and low-cost. To directly evaluate the reliability of instruments for quantitative measurements of scar properties, instruments and two qualitative scales were compared by assessing a variety of cutaneous scars.MethodsScar height and surface texture were evaluated using a 3D scanner and a mold/cast technique. Scar color was evaluated by using a spectroscopy-based tool, the Mexameter®, and digital photography with image analysis. Scar biomechanics were evaluated using the BTC-2000?, Dermal Torque Meter (DTM®), and ballistometer®. The Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS) were used to qualitatively evaluate the same scar properties. Intraclass correlation coefficients (ICC) were used to determine inter- and intra-user reliability (poor, moderate, good, excellent) with all instruments and the kappa reliability statistic was used to asses inter-user reliability (poor, fair, moderate, good, very good) for VSS and POSAS. Time for measurement collection and after collection analysis was also recorded.ResultsThe Mexameter® was the most reliable method for evaluating erythema and pigmentation compared to digital photography and image processing, POSAS and VSS. Digital photography and analysis was more reliable than POSAS and VSS. Assessment of scar height was significantly more reliable when using a 3D scanner versus VSS and POSAS. The 3D scanner and mold-cast techniques also offered an additional benefit of providing an absolute value of scar height relative to the surrounding tissue. Intra-user reliability for all mechanical tests was moderate to good. Inter-user reliability was greater when using the BTC-2000? and ballistometer® versus the DTM®. All quantitative measurements took less than 90 s for collection, with the exception of the mold/cast technique.ConclusionNon-invasive instruments allow scar properties to be quantitatively assessed with high sensitivity and as a function of time and/or treatment without the need for biopsy collection. Overall, the reliability of scar assessments was significantly improved when quantitative instruments were utilized versus scar scales. Quantitative assessment of color and biomechanics were swift, requiring less than 90 s per measurement while assessments of texture and height required additional analysis time after collection. With proper training of clinical staff and well-defined protocols for measurement collection, reliable, quantitative assessments of scar properties can be collected with little disruption to the clinical workflow.     

Diabetic foot ulcers: Epidemiology and the role of multidisciplinary care teams

Diabetic foot ulcers (DFUs) are a common but highly morbid complication of long-standing diabetes, carrying high rates of associated major amputation and mortality. As the global incidence of diabetes has increased, along with the lifespan of the diabetic patient, the worldwide burden of DFUs has grown steadily. Outcomes in diabetes and DFUs are known to depend strongly on social determinants of health, with worse outcomes noted in minority and socioeconomically disadvantaged populations. Effective treatment of DFUs is complex, requiring considerable expenditure of resources and significant cost to the health care system. Comprehensive care models with multidisciplinary teams have proven effective in the treatment of DFUs by decreasing barriers to care and increasing access to the multiple specialists required to provide timely and effective DFU procedural intervention, surveillance, and preventative care. Vascular surgeons are an integral part throughout the cycle of care for DFUs and should be involved early in the course of such patients to maximize their contributions to a multidisciplinary care model.
