Vitiligo development in a patient with psoriasis vulgaris treated with ixekizumab

Psoriasis is a chronic, immune-mediated, inflammatory multisystem skin disease with multifactorial pathogenesis causing from dys-regulated inflammation and genetic associations. 1 The use of biological agents such as TNF inhibitors, IL-12/23 inhibitors, IL-17 inhibitors, and IL-23 inhibitors to treat moderate to severe plaque psoriasis has been one of the most significant therapeutic advances in dermatol-ogy. 2 These biological agents were found to be associated with a vari-ety of skin-related side effects, ranging in frequency from 10% to 60%. 3 Here, we present a case of a 71-year-old man who developed vitiligo while being treated with ixekizumab for plaque psoriasis. A 71-year-old male patient with psoriasis for 20 years presented with lesions on the trunk and extremities. The patient's Psoriasis Area and Severity Index score was 11. There was no involvement of the patient's joints or nails. He had diabetes mellitus and chronic hepatitis B as comorbidities. The patient was on methotrexate for 2 years, cyclosporine for 4 years, and secukinumab for 3 years. The patient who did not respond to these treatments was started on ixekizumab. After 8 weeks, all of the patient's psoriasis lesions had regressed, but depigmented macules and patches had developed on the patient's cheeks and perioral areas (Figure 1). Dermatological and Wood's lamp examinations confirmed the diagnosis of vitiligo. The results of the patient's laboratory tests were normal. The patient was started on topical corticosteroids and topical pimecrolimus.
Biometrics from a wearable device reveal temporary effects of COVID-19 vaccines on cardiovascular, respiratory, and sleep physiology

Although vaccines against SARS-CoV-2 have been proven safe and effective, transient side-effects lasting 24-48 hours post-vaccination have been reported. To better understand the subjective and objective response to COVID-19 vaccination, we conducted a retrospective analysis on 69619 subscribers to a wrist-worn biometric device (WHOOP Inc, Boston, MA, USA) who received either the AstraZeneca, Janssen/Johnson & Johnson, Moderna, or Pfizer/BioNTech vaccine. The WHOOP device measures resting heart rate (RHR), heart rate variability (HRV), respiratory rate (RR), and sleep architecture, and these physiological measures were normalized to the same day of the week, one week prior to vaccination. Averaging across vaccines, RHR, RR, and percent sleep derived from light sleep were elevated on the first night following vaccination and returned to baseline within four nights post-vaccination. When statistical differences were observed between doses on the first night post-vaccination, larger deviations in physiological measures were observed following the first dose of AstraZeneca and the second dose of Moderna and Pfizer/BioNTech. When statistical differences were observed between age groups or gender on the first night post-vaccination, larger deviations in physiological measures were observed in younger populations and in females (compared to males). When combining self-reported symptoms (fatigue, muscle aches, headache, chills, or fever) with the objectively measured physiological parameters, we found that self-reporting fever or chills had the strongest association with deviations in physiological measures following vaccination. In summary, these results suggest that COVID-19 vaccines temporarily affect cardiovascular, respiratory, and sleep physiology, and that dose, gender, and age affect the physiological response to vaccination.
G2/M arrest and mitotic slippage induced by fenbendazole in canine melanoma cells

Abstract Background The use of fenbendazole (FBZ) in terminal cancer patients has recently increased, as anthelminthic drugs, such as FBZ and benzimidazole, exhibit anti‐tubulin effects in tumour cells. Objectives The present study evaluated the in vitro anti‐cancer effects of FBZ in five canine melanoma cell lines originating from the oral cavity (UCDK9M3, UCDK9M4, UCDK9M5, KMeC and LMeC). Methods Five canine melanoma cell lines were treated with FBZ and analysed with cell viability assay, cell cycle analysis, western blot assay and immunofluorescence staining to identify apoptotic effect, cell cycle arrest, microtubule disruption and mitotic slippage. Results Cell viability was reduced in all melanoma cell lines in a dose‐dependent manner after FBZ treatment. Through cell cycle analysis, G2/M arrest and mitotic slippage were identified, which showed a time‐dependent change. All treatment concentrations induced increased cleaved PARP signals in western blot analysis compared to the control groups. Immunofluorescence of cells treated for 24 h revealed defects in microtubule structure, multinucleation or macronucleation. With the exception of UCDK9M3, the melanoma cells showed mitotic slippage and post‐slippage death, indicative of mitotic catastrophe. Conclusions These results indicate that FBZ exhibits anti‐cancer effects in vitro against canine melanoma cells; however, further in vivo studies regarding the clinical applications of FBZ are required.
Does powered stapler improve the mechanical integrity of gastrojejunal anastomosis compared to the current techniques? Experimental study in ex vivo porcine models

Background: Numerous techniques have been described for fashioning gastrojejunostomy (GJ) in a Roux-en-Y gastric bypass. These include hand-sewn anastomosis (HSA) and mechanical anastomosis; the latter includes circular stapled anastomosis (CSA) or manual linear stapled anastomosis (mLSA). More recently, this list also includes powered linear stapled anastomosis (pLSA). The aim of this study was to analyse if addition of power to stapling would improve the integrity of GJ anastomosis in ex vivo porcine models. Subjects and Methods: The present study included five groups – mLSA1, mLSA2, HSA, CSA, and pLSA. Sequential infusions of methylene blue-coloured saline were performed into the GJ models. Pressure readings were recorded till the point of leak denoting burst pressure (BP). Total volume (TV) and site of leak were recorded. Compliance was calculated from the equation ΔTV/ΔBP. Results: Differences in pouch and intestinal thickness were not statistically significant between the models. BPs were higher in the mechanical anastomosis groups, i.e., pLSA 21 ± 9.85 mmHg, CSA 20.33 ± 5.78 mmHg, mLSA1 18 ± 4.69 mmHg and mLSA2 11 ± 2.94 mmHg, when compared to HSA 9.67 ± 3.79 mm Hg, which was found to be statistically significant (Kruskal–Wallis test, P = 0.03). Overall, the highest BP was recorded for powered stapling followed by circular, and then, linear stapling; however, this difference was not statistically significant (P = 0.86). There was no statistically significant difference among groups with regard to compliance (Kruskal–Wallis test, P = 0.082). Conclusion: Despite the limited number of samples, mechanical anastomosis showed a statistically higher BP when compared to HSA, suggesting better anastomotic integrity. The pLSA group showed promising results with the highest BP recorded among all groups; however, this did not reach statistical significance.
The Evolution of the Role of U.S. School Nurses in Adolescent Mental Health at the Individual, Community, and Systems Level: An Integrative Review

School nurses are crucial to addressing adolescent mental health, yet evidence concerning their evolving role has not been synthesized to understand interventions across levels of practice (i.e., individual, community, systems). We conducted an integrative review of school nurse roles in mental health in the U.S. related to depressive symptoms, anxiety, and stress. Only 18 articles were identified, published from 1970 to 2019, and primarily described school nurses practicing interventions at the individual level, yet it was unclear whether they were always evidence-based. Although mental health concerns have increased over the years, the dearth of rigorous studies made it difficult to determine the impact of school nurse interventions on student mental health outcomes and school nurses continue to feel unprepared and under supported in this area. More research is needed to establish best practices and systems to support school nursing practice in addressing mental health at all levels of practice.
Utility of Diffusion Modeling of Cogstate Brief Battery Test Performance in Detecting Mild Cognitive Impairment

Cognitive testing data are essential to the diagnosis of mild cognitive impairment (MCI), and computerized cognitive testing, such as the Cogstate Brief Battery, has proven helpful in efficiently identifying harbingers of dementia. This study provides a side-by-side comparison of traditional Cogstate outcomes and diffusion modeling of these outcomes in predicting MCI diagnosis. Participants included 257 older adults (160 = normal cognition; 97 = MCI). Results showed that both traditional Cogstate and diffusion modeling analyses predicted MCI diagnosis with acceptable accuracy. Cogstate measures of recognition learning and working memory accuracy and diffusion modeling variable of decision-making efficiency (drift rate) and nondecisional time were most predictive of MCI. While participants with normal cognition demonstrated a change in response caution (boundary separation) when transitioning tasks, participants with MCI did not evidence this change.
Incel Activity on Social Media Linked to Local Mating Ecology

Young men with few prospects of attracting a mate have historically threatened the internal peace and stability of societies. In some contemporary societies, such involuntary celibate—or incel—men promote much online misogyny and perpetrate real-world violence. We tested the prediction that online incel activity arises via local real-world mating-market forces that affect relationship formation. From a database of 4 billion Twitter posts (2012–2018), we geolocated 321 million tweets to 582 commuting zones in the continental United States, of which 3,649 tweets used words peculiar to incels and 3,745 were about incels. We show that such tweets arise disproportionately within places where mating competition among men is likely to be high because of male-biased sex ratios, few single women, high income inequality, and small gender gaps in income. Our results suggest a role for social media in monitoring and mitigating factors that lead young men toward antisocial behavior in real-world societies.
The influence of social relationships on PrEP attitudes among women with incarceration experience in the Southeastern USA

Abstract Women who have experienced incarceration face a disproportionately high risk of acquiring HIV. Despite efficacy of pre-exposure prophylaxis (PrEP) for HIV, very few women with incarceration histories are using PrEP. Our objective was to learn how sexual, drug-use and social relationships shape decisions about PrEP among women who have experienced incarceration. We used an inductive approach to analyse data from four focus groups undertaken with women who had previously experienced incarceration recruited from three community-based organisations. We identified public policy (medical distrust, lack of prevention in prisons and jails, and cost and coverage of PrEP); community (incarceration stigma, gossip as prevention); social and sexual network (positive peer and parenting relationships, distrust of sexual partners, and networks as a source of risk); and individual-level (active addiction or recovery, change after incarceration, and medical concerns) factors influencing the use of PrEP. Actions and interventions to improve PrEP uptake among women who have experienced incarceration must take account of the multilevel context of HIV prevention decisions.
Exploring the knowledge, attitudes, practices and lived experiences of frontline health workers in the times of COVID-19 : a qualitative study from Bangladesh

Objective This study explored Frontline Health Workers’ (FLWs) knowledge, attitude and practice (KAP) on COVID-19 and their lived experiences, in both their personal and work lives, at the early stage of the pandemic in Bangladesh. Design, setting and participants This was a qualitative study conducted through telephone interviews in May 2020. A total of 41 FLWs including physicians, nurses, paramedics, community healthcare workers and hospital support staff from 34 public and private facilities of both urban and rural parts of Bangladesh participated in the interview. A purposive sampling technique supplemented by a snowball sampling method was followed to select the participants. The in-depth interviews followed a semi-structured interview guide, and we applied the thematic analysis method for the qualitative data analysis. Findings Except physicians, the FLWs did not receive any institutional training on COVID-19, including its prevention and management, in most instances. Also, they had no training in the use of personal protective equipment (PPE). Their common source of knowledge was the different websites or social media platforms. The FLWs were at risk while delivering services because patients were found to hide histories and not maintaining safety rules, including physical distancing. Moreover, inadequate supply of PPE, fear of getting infected, risk to family members and ostracisation by the neighbours were mentioned to be quite common by them. This situation eventually led to the development of mental stress and anxiety; however, they tried to cope up with this dire situation and attend to the call of humanity. Conclusion The uncertain work environment during the COVID-19 pandemic simultaneously affected FLWs’ physical and emotional health in Bangladesh. However, they showed professional devotion in overcoming such obstacles and continued to deliver essential services. This could be further facilitated by a quick and targeted training package on COVID-19, and the provision of supplies for delivering services with appropriate safety precautions.
Exercise as a Moderator of Persistent Neuroendocrine Symptoms of COVID-19

Exercise attenuates the neuropsychiatric and endocrine sequelae of COVID-19 precipitated by chronic psychological stress, immune system dysregulation, and hyperinflammation. Precipitated by chronic psychological stress, immune system dysregulation, and a hyperinflammatory state, the sequelae of postacute COVID-19 (long COVID) include depression and new-onset diabetes. We hypothesize that exercise counters the neuropsychiatric and endocrine sequelae of long COVID by inducing the release of circulating factors that mediate the anti-inflammatory response, support brain homeostasis, and increase insulin sensitivity.
Role of Hepatocyte- and Macrophage-Specific PPARγ in Hepatotoxicity Induced by Diethylhexyl Phthalate in Mice

Background: Phthalates may disturb metabolic homeostasis in the liver by interfering with the peroxisome proliferator-activated receptors (PPARs). However, the role of hepatic macrophages in the lipid metabolic dysregulation induced by diethylhexyl phthalate (DEHP) remains unclear. Objectives: We aimed to evaluate the respective role of hepatocyte- and macrophage-specific PPARγ in the hepatotoxicity induced by DEHP. Methods: Wild-type (WT), hepatocyte-specific PPARγ knockout (Hep-KO), and macrophage-specific PPAR knockout (Mac-KO) mice were administered DEHP (625mg/kg body weight) by daily gavage for 28 d, followed by hepatotoxicity examination and macrophage analysis. RNA sequencing and lipid metabolomic analysis were used to characterize the molecular changes in mouse liver. Mouse bone marrow-derived macrophages (BMDMs) and human monocytic THP-1 cell-derived macrophages were used to investigate the mechanistic regulation of macrophages’ polarization by DEHP and mono(2-ethylhexyl) phthalate (MEHP). Results: The levels of hepatic steatosis and triglyceride were significantly higher in the mice treated with DEHP compared with the control mice in the WT and Hep-KO model. Lipid accumulation induced by DEHP was notably attenuated in the Mac-KO mice, but M2-polarization of hepatic macrophages in the Mac-KO mice was significantly higher compared with the WT mice under DEHP treatment. The M2-polarization of BMDMs and human macrophages was suppressed by DEHP and MEHP. Transcriptomic and lipidomic data suggested lower levels of lipid biosynthesis, fatty acid oxidation, and oxidative phosphorylation in the Mac-KO mice compared with the WT and Hep-KO mice under DEHP treatment. Conclusions: Our data suggested that the orchestrated activation of PPARα and PPARγ by MEHP may reprogram hepatic macrophages’ polarization, thereby affecting lipid homeostasis in the mouse liver. Although this conclusion was based on studies conducted in mice and in vitro, these findings may aid in elucidating the health effect of environmental phthalate exposure. https://doi.org/10.1289/EHP9373
Optimal sizing of grid integrated hybrid PV-biomass energy system using artificial bee colony algorithm

This study presents an optimal sizing methodology for a stand-alone and grid connected PV-biomass hybrid energy system that serves the electricity demand of a typical village. However, this method is scalable and can be used in any test system. A recently developed artificial bee colony (ABC) algorithm is used to detect out the optimum hybrid system configuration with the least levelised cost of energy while minimising annualised cost of the system. It has been observed from the results that a grid connected hybrid PV-biomass system is cost effective and reliable choice for rural electrification as compared with stand-alone hybrid PV-biomass energy system. It has been emerged from this study that the proposed system offers reliable and affordable electricity in a sustainable way by harnessing locally available natural resources. A brief comparison of results obtained from the ABC algorithm and hybrid optimisation model for electric renewable (HOMER) has been carried out. Moreover, it is also observed from the results that the ABC algorithm provides better results as compared with HOMER.
Exposure to multiple mycotoxins, environmental enteric dysfunction and child growth: Results from the AflaCohort Study in Banke, Nepal

Abstract Evidence of the impact of exposure to multiple mycotoxins and environment enteric dysfunction (EED) on child growth is limited. Using data from a birth cohort study, the objectives of this study were to (a) quantify exposure to multiple mycotoxins (serum aflatoxin [AFB1] and ochratoxin A [OTA], urinary fumonisin [UFB1] and deoxynivalenol [DON]), as well EED (lactulose:mannitol [L:M] ratio); (b) examine the potential combined effects of multiple mycotoxin exposure and EED on growth. Multivariate regressions were used to identify associations between growth measurements (length, weight, anthropometric z‐scores, stunting and underweight) at 24–26 months of age and exposure to mycotoxins and EED at 18–22 months (n = 699). Prevalence of AFB1, DON, OTA and UFB1 exposure ranged from 85% to 100%; average L:M ratio was 0.29 ± 0.53. In individual mycotoxin models, AFB1 exposure was negatively associated with weight, WAZ, increased odds of stunting (odds ratio [OR]: 1.28, 95% confidence interval [CI]: 1.08, 1.52; p = 0.004) and underweight (OR: 1.18, 95% CI: 1.00, 1.38; p = 0.046). Irrespective of other mycotoxin exposure and presence of EED, AFB1 was negatively associated with length, weight, head circumference, LAZ and WAZ, and with increased odds of stunting and underweight, UFB1 was associated with increased odds of underweight, and DON was negatively associated with head circumference. EED was associated with the impaired length and weight. These findings suggest that certain mycotoxins and EED may have independent impacts on different facets of growth and that aflatoxin dominates such impacts. Thus, programs reducing exposure to mycotoxin and EED through multi‐sectoral nutrition‐sensitive interventions have the potential to improve child growth.
Exogenous melatonin improves cadmium tolerance in Solanum nigrum L. without affecting its remediation potential

Abstract Although Solanum nigrum L. is a phytoremediator for different metals, its growth and physiology are still influenced by toxic levels of cadmium (Cd). Thus, the development of eco-friendly strategies to enhance its tolerance, maintaining remediation potential is of special interest. The present work aimed to evaluate the effects of exogenous application of melatonin (MT) in the physiological and biochemical responses of S. nigrum and remediation potential exposed to Cd. After 30 days of exposure, the results revealed that Cd-mediated inhibitory effects on biomass and photosynthetic pigment synthesis were efficiently mitigated upon application of melatonin, without affecting Cd accumulation. Higher levels of Cd were found in roots, regardless of the pretreatment with the melatonin. Foliar application of melatonin, however, induced distinctive effects, lowering malondialdehyde (MDA), relative electrical conductivity (REL), and proline levels in shoots. These changes contributed to improvements in the water status, photosynthetic pigment synthesis, and biomass production of S. nigrum under Cd stresses. Overall, our results indicate a protective effect of melatonin on S. nigrum response to excess Cd, contributing to a better tolerance and growth rate, without disturbing its phytoremediation potential. Novelty statement Although Solanum nigrum L. is a phytoremediator for different metals, its growth and physiology are still influenced by toxic levels of cadmium. This study evaluated the potential of melatonin to boost S. nigrum defence against Cd toward a better growth rate and remediation potential.
Qualitative study exploring the feasibility, usability and acceptability of neonatal continuous monitoring technologies at a public tertiary hospital in Nairobi, Kenya

Objective To assess the feasibility, usability and acceptability of two non-invasive, multiparameter, continuous physiological monitoring (MCPM) technologies for use in neonates within a resource-constrained healthcare setting in sub-Saharan Africa. Design A qualitative study using in-depth interviews and direct observations to describe healthcare professional and caregiver perspectives and experiences with investigational MCPM technologies from EarlySense and Sibel compared with selected reference technologies. Setting Pumwani Maternity Hospital is a public, high-volume, tertiary hospital in Nairobi, Kenya. Participants In-depth interviews were conducted with five healthcare administrators, 12 healthcare providers and 10 caregivers. Direct observations were made of healthcare providers using the technologies on 12 neonates overall. Results Design factors like non-invasiveness, portability, ease-of-use and ability to measure multiple vital signs concurrently emerged as key themes supporting the usability and acceptability of the investigational technologies. However, respondents also reported feasibility challenges to implementation, including overcrowding in the neonatal unit, lack of reliable access to electricity and computers, and concerns about cost and maintenance needs. To improve acceptability, respondents highlighted the need for adequate staffing to appropriately engage caregivers and dispel misconceptions about the technologies. Conclusion Study participants were positive about the usefulness of the investigational technologies to strengthen clinical care quality and identification of at-risk neonates for better access to timely interventions. These technologies have the potential to improve equity of access to appropriate healthcare services and neonatal outcomes in sub-Saharan African healthcare facilities. However, health system strengthening is also critical to support sustainable uptake of technologies into routine care. Trial registration number NCT03920761.
