Since COVID-19 currently has no proven cure but high morbidity and mortality; many people are living in fear of the virus along with other mental health challenges induced by the lockdowns and social distancing. Hence, this study aims to provide evidence on the co-occurrence and inter-relations between the fear of COVID-19, post-traumatic stress symptoms, and psychological distress in adherence to preventive health behavior among Nigerians. It also seeks to determine whether this process differs for men and women. The sample comprised 1,172 consenting young adults (mean age = 22.9 ± 6.6 years, 54.5% females) selected using a snowball sampling technique. Structural equation modeling (SEM) was used to test the mediation model of post-traumatic stress symptoms and psychological distress as parallel and serial mediators of the relationship between the fear of COVID-19 and preventive health behavior. The indirect effect of the fear of COVID-19 on preventive health behavior across gender was tested using moderation analysis. Results showed that post-traumatic stress symptoms and psychological distress serially and fully, in causal order, mediated the association between the fear of COVID-19 and preventive health behavior, and gender moderated the mediation effects. The research provides evidence that the fear of COVID-19 could trigger preventive health behavior through post-traumatic stress symptoms but reduces it through psychological distress, whereas the fear of COVID-19 has a slightly more positive impact on preventive health behavior among men.

Infected diabetic foot is the leading cause of hospital admissions for people with diabetes mellitus. Diabetic foot osteomyelitis (DFO) causes high morbidity and significant mortality. Current diagnostic tests for DFO are either expensive, invasive, or of low diagnostic yield.

The objective of the study was to determine whether serum levels of procalcitonin (PCT), an inflammatory marker, differ between DFO and diabetic foot ulcers without osteomyelitis (ie, cellulitis) as controls. The authors also aimed to assess the usefulness of PCT in diagnosing DFO.

A case-control study was designed comparing DFO with diabetic foot cellulitis as the control. Patients were classified as having osteomyelitis and cellulitis based on the International Working Group on the Diabetic Foot diagnostic criteria. Serum inflammatory markers PCT, adiponectin, C-reactive protein-1, osteoprotegerin (OPG), osteopontin (OPN), and interleukin 6 (IL-6) were analyzed in patients with DFO and controls.

The median serum procalcitonin ies in a larger population are needed to verify the findings.

When closure is not feasible, Mohs micrographic surgical wounds typically are left to heal by secondary intention and require weeks to close. Amniotic tissue-derived allograft (ATDA) has proven successful in promoting wound closure in diabetic and refractory wounds, and it may be beneficial for patients who have undergone Mohs micrographic surgery.

The authors conducted a preliminary study to assess the efficacy of ATDA in speeding wound closure time and improving cosmetic outcomes in the specified patient population.

Patients received an injection of amniotic fluid, an overlay of amniotic membrane, or standard of care. Photographs of wounds taken at the time of treatment and at each subsequent visit were analyzed.

The cosmetic outcome and time to wound closure appeared to be improved in patients treated with ATDA when compared with expected outcomes. Owing to small sample size, differences in initial defect size, and variety of body locations, the wound closure rate between treatment groups was not found to be significantly different with most comparisons. Statistical significance was seen, however, when normalized closure rates between membrane and control intervention were compared after outlier analysis (P = .0288).

Data indicate that ATDA treatment may be beneficial and suggest that further investigation of the efficacy of ATDA to promote wound healing and improve cosmetic outcomes of post-Mohs surgical wounds is warranted. Future studies should be designed to match initial defect size and location between control and treatment groups.

Skin defects-especially infected, massive full-thickness defects-can be challenging to manage. MS1943 supplier Traditionally, defects are repaired using free flaps or musculocutaneous flaps.Many side effects and complications are associated with flaps, however, such as infection, pain, donor site pain, and poor cosmesis.

This case series evaluates the use of an adjustable, skin-stretching external fixation device and negative pressure wound therapy (NPWT) to repair soft tissue defects.

In this retrospective series, 7 patients with skin defects were treated with an adjustable, skin-stretching external fixation device and NPWT between January 2014 and December 2017. All patients were followed until complete healing was achieved. Each patient's age, sex, defect size, mechanism of injury, healing time, results, and complications were recorded.

The average patient age was 37.43 years ± 10.47 SD (range, 26-55 years). The average skin defect area was 14.5 cm2 ± 5.26 * 23.25 ± 9.01 cm2 (range, 7-15 cm2 * 10-30 cm2), and average healing time was 3.29 months ± 1.60 (range, 1-6 months). All defects healed, and 2 patients developed ulcers.

This series showed the adjustable, skin-stretching external fixation device and NPWT to be a simple, safe, and effective means of managing skin defects, with minimal complications.

The Pfizer-BioNTech COVID-19 vaccine uses a novel messenger RNA technology to elicit a protective immune response. Short-term physiologic responses to the vaccine have not been studied using wearable devices.

We aim to characterize physiologic changes in response to COVID-19 vaccination in a small cohort of participants using a wearable device (WHOOP Strap 3.0). This is a proof of concept for using consumer-grade wearable devices to monitor response to COVID-19 vaccines.

In this prospective observational study, physiologic data from 19 internal medicine residents at a single institution that received both doses of the Pfizer-BioNTech COVID-19 vaccine was collected using the WHOOP Strap 3.0. The primary outcomes were percent change from baseline in heart rate variability (HRV), resting heart rate (RHR), and respiratory rate (RR). Secondary outcomes were percent change from baseline in total, rapid eye movement, and deep sleep. Exploratory outcomes included local and systemic reactogenicity following each dose and prophylactic analgesic use.
