Effects of the COVID-19 Pandemic On Patient Social Media Use and Acceptance of Cosmetic Procedures.

Objective: We sought to explore facets of social media usage and the effect of the COVID-19 pandemic on the acceptance of cosmetic procedures. Methods: At an outpatient dermatology clinic from October 2019 to June 2022, 175 subjects who were English and Spanish speaking and aged 18 years or older were recruited. Participants completed a questionnaire including demographic information, social media usage, perceptions of cosmetic procedures, and desire to have a cosmetic procedure. Results were grouped into a pre-COVID-19 pandemic group and post-COVID-19 pandemic group due to a natural experiment that arose. Data were analyzed to ascertain the effect of social media usage and other factors that impact desire to undergo a cosmetic procedure between patients before and after the COVID-19 pandemic. Results: Factors resulting in differences in desire to have a cosmetic procedure included using photo editing applications (p=0.002), following celebrities and influencers on social media (p<0.001), and following social media accounts showing cosmetic results (p=0.013). There was a statistically significant change in number of participants that: followed social media accounts showing results of cosmetic procedures (pre-COVID: 31.9%, post-COVID: 50.6%, p=0.036); had thought about having a cosmetic procedure done (pre-COVID: 63.8%, post-COVID: 86.4%, p<0.001); had discussed cosmetic procedures with a physician, dermatologist, or other professional (pre-COVID: 43.6%, post-COVID: 67.9%, p=0.001); and believed that a cosmetic procedure would help their self-esteem (pre-COVID: 47.9%, post-COVID: 77.8%, p<0.001). Limitations: Limitations of this study include response bias, recall bias, and single institution study design, limiting generalizability. Conclusion: Our findings suggest that time spent on social media and use of photo-editing applications significantly contributes to desire to undergo a cosmetic procedure and contributed to the rise of cosmetic consultations during the COVID-19 pandemic.

Efficacy of remote audio-visual system versus standard onsite buddy system to monitor the doffing of personal protective equipment during COVID-19 pandemic: An observational study.

OBJECTIVES: Literature states a higher self-contamination rate among healthcare workers (HCWs) while doffing personal protective equipment (PPE). During the Covid-19 pandemic, onsite trained observers were not always available to monitor PPE compliance. The remote audio-visual doffing surveillance (RADS) system has the potential to overcome this limitation. We aimed to compare the efficacy of this real-time RADS system against the onsite buddy system for monitoring the doffing of PPE. METHODS: This prospective, observational study was carried out at our tertiary care centre in northern India. 200 HCWs who cared for Covid-19 patients in the intensive care units/operation theatres were included. Group A included HCWs who performed doffing with the help of an onsite trained observer and group B included HCWs who performed doffing with the RADS system. An independent observer noted the error at any step using the CDC doffing checklist, in both groups. An online questionnaire to analyse the level of satisfaction post-doffing was also surveyed. RESULTS: The proportion of errors committed during doffing was significantly lower in group B compared to group A with a low relative risk of 0.34 (95% CI 0.22-0.51) (p < 0.001) (Figure 1A,B). In both groups, there was no difference in HCWs feedback regarding the ease of the system and fear of committing an error. Though the perceived quality of monitoring was felt better with onsite buddy, the overall confidence rating of being safe after doffing was better with the RADS system. CONCLUSION: Real-time RADS system may be more effective than the onsite buddy system for ensuring the safety of HCWs during doffing PPE. HCWs level of satisfaction related to the ease and anxiety with the monitoring systems were comparable. RADS system can reduce reliance on HCW resources and can integrate well into existing healthcare systems.

Consumer Preferences of Topical Vitamin C Products: A Comparative Study.

Hyperpigmentation disorders greatly impact the quality of life of many patients. Vitamin C and ascorbic acid derivatives are commonly used as topical agents to reduce the effect of facial dyschromia. The market for vitamin C topicals has greatly increased, but with little oversight, resulting in a wide variety of products with regard to purity and efficacy. In this study, we conducted an analysis of the most highly rated vitamin C-containing compounds on Amazon and Sephora. It was found that consumers for both retailers prioritized efficacy and cosmetic elegance in their rating of products. Additionally, consumers displayed no preference among vitamin C derivatives in the products available to them. This study highlights the diverse vitamin C formulations currently available as well as consumer preferences, emphasizing the importance of fully reviewing all products patients are utilizing to better counsel on treatment regimens.

Exogenous Ochronosis: Characterizing a Rare Disorder in Skin of Color.

Exogenous ochronosis is a rare dyschromia that primarily impacts those with skin of color. It is characterized by blue-black pigmentation and is associated with the long-term application of skin-lightening creams containing hydroquinone. Commonly confused with other dyschromias, the use of skin lightening topicals can cause paradoxical skin darkening in patients with known exogenous ochronosis. This is highly distressing to patients, often worsening the underlying dyschromia and making treatment more difficult. A 10-year retrospective analysis was conducted that revealed 25 patients with exogenous ochronosis. The average patient used a skin lightening cream for 9.2 years, with exogenous ochronosis most commonly arising on the cheeks (68%), forehead (24%), and temples (20%). Furthermore, this study identified that patients with exogenous ochronosis may respond well to treatment with Q-switched Alexandrite laser and microneedling. The incidence of exogenous ochronosis is likely to increase as demographics shift and access to a wide range of over-the-counter topicals becomes more available, both in the United States and worldwide. Therefore, it is imperative to better characterize exogenous ochronosis to identify best treatment practices for all patients.

Patient-centered Outcomes for Individuals with a Venous Leg Ulcer: A Scoping Review.

GENERAL PURPOSE: To summarize randomized clinical trials addressing patient-centered outcomes of individuals with a venous leg ulcer. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Summarize the results of the review of randomized controlled trials addressing patient-centered outcomes of individuals with a venous leg ulcer.2. Identify the limitations of the research analyzed for the review.

To summarize randomized clinical trials addressing patient-centered outcomes of individuals with a venous leg ulcer with a scoping review. Authors searched PubMed using MESH terms for "venous ulcer" AND "randomized" for randomized clinical trials published from January 2002 to October 2021 that explored content-validated patient-centered outcomes for individuals with a clinically diagnosed venous leg ulcer. Authors also searched Cochrane Reviews from inception to April 15, 2022 for additional references using the same MESH terms. Studies in any setting were included if primary or secondary outcomes were venous ulcer-related mobility, pain or analgesic use, healing, infection, quality of life (including odor, social isolation, depression), amputation, or patient-level costs of treatment. Preclinical or nonrandomized clinical studies or those without venous leg ulcers were excluded. Authors tabulated interventions studied, numbers of patients treated per group, risk of delayed ulcer healing, and statistical significance of comparisons of 485 qualifying articles in Google Sheets. Authors graphically represented and tabulated frequencies of studies addressing patient-centered outcomes of individuals with venous ulcers. Studies mainly reported effects of compression, dressings, topical antimicrobials, or systemic therapy on patient healing or pain outcomes. Related ischemia, ultrasonography, or risk factors for delayed healing were not consistently reported, inflating variability of outcomes and decreasing consistency of differences reported. Research is needed on the mobility, amputation risk, infection risk, quality of life, and healthcare costs of patients with venous ulcers. Promising interventions include grafts, exercise, analgesics, electrical modalities, negative pressure, or vascular interventions. Consistently reporting each patient's baseline ischemia and vascular condition would improve relevance.

Incidence & outcomes of clinically significant bleeding events in critically ill COVID-19 patients receiving Therapeutic dose AntiCoagulanTs: A retrospective cohort study (INTerACT study).

Background & objectives: The high mortality associated with the thrombotic events in hospitalized COVID-19 patients resulted in the usage of anticoagulants in varying doses. Whether high-dose anticoagulants have led to better outcomes or higher incidence of clinically significant bleeding events is debatable. Thus, this study was conducted to find the incidence of clinically significant bleeding events in moderate-to-severe COVID-19 ARDS (acute respiratory distress syndrome) patients on therapeutic anticoagulation and their outcomes. Methods: In this retrospective, single-centre study of 155 critically ill COVID-19 patients, the incidence of clinically significant bleeding was observed. Multivariate regression models were used to evaluate the association between anticoagulant regimen, coagulation and inflammatory markers with the incidence of bleeding and thrombotic events. Results: The incidence of clinically relevant non-major bleeding was 33.54 per cent (26.17-41.46%) and major bleeding was 9.03 per cent (5.02-14.69%). The anticoagulation intensity at baseline had a high odds of major bleeding when enoxaparin and dual antiplatelet therapy were used together [adjusted odds ratio OR of 434.09 (3.81-49502.95), P<0.05]. At admission, bleeders had a poorer PaO2/FiO2 ratio with more patients on invasive ventilation. At the time of bleeding, the bleeders had a higher D-dimer, ferritin, C-reactive protein and procalcitonin compared to non-bleeders. The subhazard ratio for death in bleeders was 3.35 (95% confidence interval, 1.97-5.65; P<0.001). Interpretation & conclusions: The incidence of bleeding in critically ill COVID-19 patients on therapeutic anticoagulation may increase with the severity of the disease as well as with concurrent use of dual antiplatelets. Major bleeding may also contribute to higher mortality.

GH Action in Prostate Cancer Cells Promotes Proliferation, Limits Apoptosis, and Regulates Cancer-related Gene Expression.

Previous studies investigating the effects of blocking the growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis in prostate cancer found no effects of the growth hormone receptor (GHR) antagonist, pegvisomant, on the growth of grafted human prostate cancer cells in vivo. However, human GHR is not activated by mouse GH, so direct actions of GH on prostate cancer cells were not evaluated in this context. The present study addresses the species specificity of GH-GHR activity by investigating GH actions in prostate cancer cell lines derived from a mouse Pten-deletion model. In vitro cell growth was stimulated by GH and reduced by pegvisomant. These in vitro GH effects were mediated at least in part by the activation of JAK2 and STAT5. When Pten-mutant cells were grown as xenografts in mice, pegvisomant treatment dramatically reduced xenograft size, and this was accompanied by decreased proliferation and increased apoptosis. RNA sequencing of xenografts identified 1765 genes upregulated and 953 genes downregulated in response to pegvisomant, including many genes previously implicated as cancer drivers. Further evaluation of a selected subset of these genes via quantitative reverse transcription-polymerase chain reaction determined that some genes exhibited similar regulation by pegvisomant in prostate cancer cells whether treatment was in vivo or in vitro, indicating direct regulation by GH via GHR activation in prostate cancer cells, whereas other genes responded to pegvisomant only in vivo, suggesting indirect regulation by pegvisomant effects on the host endocrine environment. Similar results were observed for a prostate cancer cell line derived from the mouse transgenic adenocarcinoma of the mouse prostate (TRAMP) model.

Neurosurgical Emergency in an Adult With Single Ventricle Physiology: A Case Report.

The anesthetic management of a patient with uncorrected congenital heart disease presenting for noncardiac surgery is quite challenging. When this becomes a neurosurgical emergency, the need to balance cerebral and complex circulatory physiologies tests the anesthesiologist's preparedness. The principal clinical challenges we faced were preventing increases in intracranial pressure while maintaining the circulatory physiology using the "cardiac grid" approach to hemodynamic management in a case of acyanotic double outlet right ventricle with a posterior fossa space-occupying lesion. Point of care preoperative echocardiography enabled us to understand the altered circulatory physiology and successfully manage this patient.

Performance of Health Care Workers in Doffing of Personal Protective Equipment Using Real-Time Remote Audio-Visual Doffing Surveillance System: Its Implications for Bio-Safety Amid COVID-19 Pandemic.

Background Very little has been reported about health care workers' (HCWs) adherence to the Centers for Disease Control and Prevention (CDC) guidelines of doffing personal protective equipment (PPE) amid the COVID-19 pandemic. Real-time remote audio-visual doffing surveillance (RADS) system for assisting doffing might reduce the risk of self-contamination. We used this system to determine the incidence of the breach in biosafety during doffing of PPE among HCWs involved in the care of Covid-19 patients. Methods A total of 100 HCWs were enrolled in this observational study who performed duties in the COVID intensive care unit (ICU) of our tertiary care centre. With a real-time RADS system, trained observers from remote locations assisted HCWs during doffing of PPE and noted breach at any step using the CDC doffing checklist. The breach was considered major if committed during removal of gloves/gown/N-95 or if ≥3 errors occurred in any other steps. Results Overall, 40% of the HCWs committed a breach during doffing at least one step. The majority of the errors were observed during hand hygiene (34%), followed by glove removal (12%) and N-95 removal (8%). Nineteen percent of HCWs committed the major breach, out of which 37.5% were done by house-keeping sanitation staff (p = 0.008 and RR 2.85; 95% CI of 1.313-6.19), followed by technicians (22.5%), nursing staff (16.7%) and resident doctors (6.5%). Conclusions Performing doffing using a real-time RADS system is associated with a relatively low incidence of a breach in biosafety compared with earlier studies using an onsite standard observer. Overall adherence of HCWs to the CDC guidelines of doffing PPE was satisfactory. This study highlights the importance of the RADS system during doffing of PPE in a health care setting amid the COVID-19 pandemic.

Mammary Tumors Growing in the Absence of Growth Hormone Are More Sensitive to Doxorubicin Than Wild-Type Tumors.

Previously, we reported that N-methyl-N-nitrosourea (MNU)-induced mammary tumors could be established in mutant spontaneous dwarf rats (SDRs), which lack endogenous growth hormone (GH) by supplementing with exogenous GH, and almost all such tumors regressed upon GH withdrawal. When the highly inbred SDR line was outcrossed to wild-type (WT) Sprague-Dawley rats, MNU-induced mammary tumors could still be established in resulting outbred SDRs by supplementing with exogenous GH. However, unlike tumors in inbred SDRs, 65% of mammary tumors established in outbred SDRs continued growth after GH withdrawal. We further tested whether these tumors were more sensitive to doxorubicin than their WT counterparts. To accomplish this, MNU-induced mammary tumors were established in WT rats and in SDRs supplemented with exogenous GH. Once mammary tumors reached 1 cm3 in size, exogenous GH was withdrawn from SDRs, and the subset that harbored tumors that continued or resumed growth in the absence of GH were selected for doxorubicin treatment. Doxorubicin was then administered in 6 injections over 2 weeks at 2.5 mg/kg or 1.25 mg/kg for both the WT and SDR groups. The SDR mammary tumors that had been growing in the absence of GH regressed at both doxorubicin doses while WT tumors continued to grow robustly. The regression of SDR mammary tumors treated with 1.25 mg/kg doxorubicin was accompanied by reduced proliferation and dramatically higher apoptosis relative to the WT mammary tumors treated with 1.25 mg/kg doxorubicin. These data suggest that downregulating GH signaling may decrease the doxorubicin dose necessary to effectively treat breast cancer.

High-Dose Dexamethasone Versus Tocilizumab in Moderate to Severe COVID-19 Pneumonia: A Randomized Controlled Trial.

Background and objectives Recent randomized controlled trials (RCTs) have indicated potential therapeutic benefits with high-dose dexamethasone (HDD) or tocilizumab (TCZ) plus standard care in moderate to severe coronavirus disease 2019 (COVID-19) with acute respiratory distress syndrome (ARDS). No study has compared these two against each other. We aimed to compare the efficacy and safety of HDD against TCZ in moderate to severe COVID-ARDS. Methods Patients admitted with moderate to severe COVID-19 ARDS with clinical worsening within 48 hours of standard care were randomly assigned to receive either HDD or TCZ plus standard care. The primary outcome was ventilator-free days (VFDs) at 28 days. The main secondary outcomes were 28-day all-cause mortality and the incidence of adverse events. Our initial plan was to perform an interim analysis of the first 42 patients. Results VFDs were significantly lower in the HDD arm (median difference: 28 days; 95% confidence interval (CI): 19.35-36.65; Cohen's d = 1.14;p < 0.001). We stopped the trial at the first interim analysis due to high 28-day mortality in the HDD arm (relative risk (RR) of death: 6.5; p = 0.007; NNT (harm) = 1.91). The incidence of secondary infections was also significantly high in the HDD arm (RR: 5.5; p = 0.015; NNT (harm) = 2.33). Conclusions In our study population, HDD was associated with a very high rate of mortality and adverse events. We would not recommend HDD to mitigate the cytokine storm in moderate to severe COVID-19 ARDS. TCZ appears to be a much better and safer alternative.

Two-Stage Fiberoptic Intubation in an Infant With a Rare Congenital Laryngopharyngo-Cutaneous Fistula: A Case Report.

Branchial arches represent embryological precursors of the face, neck, and pharynx, and developmental abnormalities of these branchial arch derivatives can lead to airway anomalies. We report definitive repair of the fistula in an infant with a rare congenital laryngopharyngo-cutaneous fistula. This is the first report that describes a 2-stage fiberoptic intubation, a challenging technique performed for airway management of the aforementioned fistula in a patient with a difficult airway.

Update About the Effects of the Sunscreen Ingredients Oxybenzone and Octinoxate on Humans and the Environment.

As skin cancer prevalence continues to rise, the importance of sun protection, including sunscreen use, has become accepted in the public. Sunscreens are divided into two main categories based on the type of their active ingredient, organic and inorganic ultraviolet (UV) filters. It has been shown that inorganic filters are more effective at blocking forms of UV light, both UVA and UVB, as compared with organic filters because organic sunscreens absorb and convert radiation whereas inorganic sunscreens reflect radiation. The use of the two most common organic filters, oxybenzone and octinoxate, has recently been restricted in Hawaii due to their harmful effect on the coral reefs. Here, we discuss recent studies about these specific filters related to the adverse health risks they pose for humans and other organisms, as well as environmental repercussions.
