Distal pancreatectomy with splenectomy is the gold-standard surgery for the treatment of left-sided pancreatic cancer. Margin negative resection accompanied by effective lymphadenectomy are the deciding factors affecting the outcome of tail-body pancreatic adenocarcinoma. Radical antegrade modular pancreatosplenectomy (RAMPS) is considered as a reasonable approach for margin-negative and systemic lymph node clearance. Herein, we aim to present all existing data regarding this novel approach including surgical technique and comparison with standardized procedures. RAMPS has shown oncological superiority comparing to distal pancreatectomy with splenectomy due to radical lymphadenectomy and improved dissection of the posterior pancreatic aspects. Robotic-assisted RAMPS has recently been described as a valuable alternative to open RAMPS. With this novel technique, anterior, posterior or modified approaches can be achieved; favorable clinical and oncological outcomes have been reported in the current literature, with reduced conversion rates compared to other minimally invasive approaches, as well as vastly improved maneuverability, accuracy and vision. Robotic-assisted RAMPS is not only technically feasible but also oncologically safe in cases of well-selected, left-sided pancreatic cancer.

Background/Aim: We aimed to assess the risk factors for postoperative complications and long-term outcome of patients aged ≥80 years after curative resection for gastric cancer (GC). Patients and Methods: Patients aged ≥80 years who underwent curative gastrectomy for stage I-III GC between 2013 and 2020 were included. Clinical factors were retrospectively analyzed. Results: Of all 109 patients, 29 (26.6%) had 33 postoperative complications (Clavien–Dindo grade ≥2). The rate of postoperative complications was higher in those with greater blood loss (≥170 ml, p<0.001). In multivariate analysis, greater blood loss was confirmed as an independent predictor of postoperative complications (p<0.001). The 30-day, 180-day, 1-year, and 3-year cumulative overall survival rates were 100%, 97.0%, 91.6%, and 74.7%, respectively. Multivariate analysis showed postoperative complications (p=0.014) and low prognostic nutritional index (PNI, p=0.044) were independent prognostic factors for poor overall survival. Conclusion: Performing operations with less bleeding is important to reduce postoperative complications. According to the analysis of long-term survival, patients who experience postoperative complications and patients with a low preoperative PNI require special attention in the follow-up period. Nutritional support should be considered in patients with malnutrition.

Background/Aim: The safety of gastrectomy for patients receiving antithrombotic agents remains unclear. This retrospective cohort study sought to compare outcomes between patients who did and did not receive antithrombotic agents. Patients and Methods: This single-center retrospective cohort study included 548 patients who underwent gastrectomy for primary gastric adenocarcinoma from January 2011 to December 2019. The surgical outcomes were compared between two groups according to whether they received antithrombotic therapy (n=121) or not (n=427). Results: Among the entire cohort, the patients in the antithrombotic therapy group were significantly older than those who did not receive this therapy and had significantly higher postoperative complication rates than those who did not (33.1% vs. 23.9%; p=0.046). However, after propensity score matching, no significant difference in the postoperative complication rate was observed between the two groups. Conclusion: Despite having a high risk for postoperative complications, patients receiving antithrombotic therapy can safely undergo gastric resection.

Published: March 2022

Background/Aim: This study analyzed the parameters provided by preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for prognostic prediction of renal cell carcinoma (RCC). Patients and Methods: FDG-PET/CT data from 66 clear cell RCC and 19 non-clear cell RCC cases between January 2015 and October 2018 were reviewed retrospectively. We compared the two groups according to recurrence/metastasis to determine prognosis-influencing factors. Multivariate Cox hazard regression models were constructed to evaluate factors potentially predicting disease-free survival (DFS) after adjustment for confounders. DFS was then compared between groups. Results: Standardized uptake values (SUV) of the PET/CT scan were independent predictors of prognosis after adjusting for confounders. RCC cases were divided into two groups by optimal cut-off values. Differences between DFS percentages in high and low SUV groups were significant. Similar results were obtained in clear cell RCC groups. Conclusion: Increased SUV of the PET/CT scan are significant predictors of worse prognoses in patients with surgically resected RCC.

Published: March 2022

Background/Aim: To evaluate the preventive effects of regional lymph node irradiation on lymph node recurrence in esophageal cancer (EC). Patients and Methods: The study included 289 patients who received definitive radiotherapy for EC. The regional lymph node area of group 1 was determined as the area with the highest probability of lymph node metastasis and group 2 was determined as the area with the next highest probability of lymph node metastasis depending on the primary site of EC. Results: The patients in whom group 2 was completely included in the irradiated field had a significantly lower rate of recurrence of regional lymph node metastasis than those in whom group 2 was not or insufficiently included (p=0.0337). There was no significant difference in overall survival (p=0.4627) or disease-specific survival (p=0.6174) between the two groups. Conclusion: Regional lymph node irradiation did not have survival-prolonging effects but significantly reduced regional lymph node recurrence.

Published: March 2022

Background/Aim: Undifferentiated pleomorphic sarcoma (UPS), previously called as malignant fibrous histiocytoma, is a mesenchymal neoplasm which shows no identifiable cellular differentiation when analyzed by presently available technology. UPS in the periocular region is extremely rare. This study describes a patient with UPS arising in the conjunctiva with literature review. Case Report: A 66-year-old man presented with a congested mass on the bulbar conjunctiva. The mass was totally excised. Histopathologically, it was a dome-shaped tumor comprising atypical short spindle cells growing as pattern-less pattern, with enlarged nuclei and eosinophilic cytoplasm. Based on immunohistochemistry, the direction of cellular differentiation was unidentifiable; therefore, it was diagnosed as UPS. The tumor showed high Ki-67 labeling index (70~80%). Conclusion: Twelve patients with conjunctival UPS have been reported with an average age of 49 years. Eight tumors of the 12 patients were observed in the limbus, and the rest in the bulbar conjunctiva. The appearance of the tumors was yellow, tan, pink, brown, or vascularized. Histopathologically, the tumors consisted of spindle-shaped cells with pleomorphism and many mitotic figures. In conclusion, conjunctival UPS is a rare malignancy with various colors, which can show aggressive nature. UPS should be differentiated from other conjunctival malignancies based on histopathological and immunohistochemical examinations including Ki-67.

Published: March 2022

Background: Langerhans cell histiocytosis (LCH) is a rare disease, especially in adults. It is often associated with non-fatal bone and skin lesions and has relatively good radiosensitivity. In contrast, brain and lymph node metastases from LCH lesions are considered to be less sensitive to radiotherapy. Case Report: At our institution, 30 Gy radiotherapy was used to treat bone lesions with dural invasion in a patient with adult-onset LCH. The patient was treated with chemotherapy and radiotherapy for 21 years since the initial diagnosis. After radiotherapy, the tumor shrank rapidly, and a complete response was achieved 1 year after treatment. The patient survived without local recurrence. Conclusion: Here, we report the details of this case, along with a review of the literature. We suggest that even with invasion of the tissues around the bone lesions in LCH, local recurrence can be prevented by middle radiation doses.

Authors: Gardiner Paula , McGonigal Lisa , Villa Ariel , Kovell Lara C , Rohela Pallavi , Cauley Andrew , Rinker Diana , Olendzki Barbara
Published: March 2022

Background

Hypertension (HTN) affects millions of Americans. Our Whole Lives: an eHealth toolkit for Hypertension and Cardiac Risk Factors (OWL-H) is an eHealth platform that teaches evidence-based lifestyle strategies, such mindfulness and cooking skills, to improve self-management of HTN.

Objective

The primary goal of this pilot study was to evaluate the feasibility of OWL-H combined with teaching kitchen medical group visits (TKMGVs) in a low-income population of participants with HTN.

Methods

We conducted a pre-post 8-week study to assess the feasibility of a hybrid program (a web-based 9-module self-management program, which includes mindfulness and Mediterranean and Dietary Approaches to Stop Hypertension diet) accompanied by 3 in-person TKMGVs among patients with HTN. Data including demographics, platform use, and satisfaction after using OWL-H were examined. Outcome data collected at baseline and 8 weeks included the Mediterranean Diet Questionnaire, Hypertension Self-Care Profile Self-Efficacy Instrument, Blood Pressure Knowledge Questionnaire, and the number of self-reported blood pressure readings. For the statistical analysis, we used descriptive statistics, paired sample t tests (1-tailed), and qualitative methods.

Results

Of the 25 enrolled participants, 22 (88%) participants completed the study. Participants’ average age was 57 (SD 12.1) years, and 46% (11/24) of them reported a household income <US $30,000 per year. Among the 22 participants who logged in to OWL-H, the average number of mindfulness practices completed was 7 and the average number of module sessions accessed was 4. In all, 73% (16/22) of participants reported that they were “very satisfied” with using OWL-H to help manage their HTN. Participants’ blood pressure knowledge significantly increased from baseline (mean 5.58, SD 1.44) to follow-up (mean 6.13, SD 1.23; P=.03). Participants significantly increased their adherence to a Mediterranean diet from baseline (mean 7.65, SD 2.19) to follow-up (mean 9, SD 1.68; P=.004). Participants’ self-efficacy in applying heart-healthy habits, as measured by the Hypertension Self-Care Profile Self-Efficacy Instrument, increased from baseline (mean 63.67, SD 9.06) to follow-up (mean 65.54, SD 7.56; P=.14). At the 8-week follow-up, 82% (18/22) of the participants had self-reported their blood pressure on the OWL-H platform at least once during the 8 weeks.

Conclusions

The eHealth platform for HTN self-management, OWL-H, and accompanying in-person TKMGVs have the potential to effectively improve lifestyle management of HTN.

Authors: Oh Sarah Soyeon , Moon Jong Youn , Chon Doukyoung , Mita Carol , Lawrence Jourdyn A , Park Eun-Cheol , Kawachi Ichiro
Published: March 2022

Background

Alcohol consumption in pregnancy has been associated with serious fetal health risks and maternal complications. While previous systematic reviews of digital interventions during pregnancy have targeted smoking cessation and flu vaccine uptake, few studies have sought to evaluate their effectiveness in preventing alcohol consumption during pregnancy.

Objective

This systematic review aims to assess (1) whether digital interventions are effective in preventing alcohol consumption during the pregnancy/pregnancy-planning period, and (2) the differential effectiveness of alternative digital intervention platforms (ie, computers, mobiles, and text messaging services).

Methods

PubMed, Embase, CINAHL, and Web of Science were searched for studies with digital interventions aiming to prevent alcohol consumption among pregnant women or women planning to become pregnant. A random effects primary meta-analysis was conducted to estimate the combined effect size and extent to which different digital platforms were successful in preventing alcohol consumption in pregnancy.

Results

Six studies were identified and included in the final review. The primary meta-analysis produced a sample-weighted odds ratio (OR) of 0.62 (95% CI 0.42-0.91; P=.02) in favor of digital interventions decreasing the risk of alcohol consumption during pregnancy when compared to controls. Computer/internet-based interventions (OR 0.59, 95% CI 0.38-0.93) were an effective platform for preventing alcohol consumption. Too few studies of text messaging (OR 0.29, 95% CI 0.29-2.52) were available to draw a conclusion.

Conclusions

Overall, our review highlights the potential for digital interventions to prevent alcohol consumption among pregnant women and women planning to become pregnant. Considering the advantages of digital interventions in promoting healthy behavioral changes, future research is necessary to understand how certain platforms may increase user engagement and intervention effectiveness to prevent women from consuming alcohol during their pregnancies.

Authors: Suthar Shweta , Kumar Dr. Dinesh
Published: March 2022

Abstract: In recent years, the use of fiber reinforced polymer composites in variety of applications play a major role due to their attractive properties such as light weight, fatigue resistance, easy moldability, high specific strength and modulus. Earlier researchers in past studies have shown that synthetic fiber reinforced polymer composites obtained a better mechanical properties but the applications are restricted to less because of high procurement and manufacturing cost and more weight. To overcome these, nowadays light weight natural fiber reinforced polymer composites are very widely used in the field of automobile, Aerospace, Marine, and Furniture’s applications because of their recyclability, easy availability and low cost of materials and production. Human hair is a versatile material identified with a significant potential in the use of reinforcement in composites due to its excellent material properties. The present work concentrates on the fabrication and study of various physical, mechanical and thermal properties of natural fiber reinforced thermo-set polymer matrix composites. The fabrication was done for eight different types of new set of natural fiber polymer composites which consist of human hair as reinforcement, Epoxy and Vinylesteras the resin with four different set of fiber volume fractions (70:30, 75:25, 80:20, 85:15 ratio of matrix and fiber respectively) using hand layup technique. Then the samples were prepared according to ASTM standard for testing mechanical properties such as Impact Energy, Rockwell Hardness and physical properties such as Density and water absorption. Theoretical density of composites was determined for validating actual density of fabricated composites. Rockwell Hardness was measured on both dry and water absorbed composite samples. Internal structure between fiber and matrix was analyzed by using Scanning Electron Microscope (SEM).

Published: March 2022

In practice, different methods are used to assess the financial health of a company, and the fact that models use the various indicators complicates the comparison of their results. The aim of this paper was to identify the financial health of agricultural enterprises operating in the Slovak Republic using three selected creditworthy models (the Altman model, Taffler model and Bonity Index). It was concluded that the differences in the evaluations of agricultural enterprises using individual creditworthy models were significant. The analysis was supplemented by the spatial distribution of the enterprises at the level of individual regions of the Slovak Republic. It was confirmed that the spatial differences in the evaluations of agricultural enterprises using individual creditworthy models were not statistically significant and were therefore random. The proposal of own assessment of regions is based on the combination of the obtained results and their spatial distribution. We assume that such comprehensive assessment over a longer period of time may be an appropriate tool for assessing the financial health of agricultural enterprises, thus contribute to the early identification of potential risks and the long-term economic sustainability. This study can be the contribution in helping to design policies or effective solve the important challenges of agricultural enterprises to the path of sustainable development of the regions and to environmental management.
COVID-19 Exposure Risk, Burnout, and Shifts in Family Medicine Faculty’s Efforts: A National Survey
Authors: Ferber Megan  Ferriby , Zubatsky Max , Jacobs Christine K. , Cronholm Peter F.
Published: March 2022

Background and Objectives: In response to the COVID-19 pandemic, academic family physicians had to change their clinical, teaching, research, and administrative efforts, while simultaneously balancing their home environment demands. It is unclear how the changes in effort affected physicians’ personal well-being, particularly burnout. This study sought to identify changes in faculty’s clinical, teaching, research, and administrative efforts during the COVID-19 pandemic and how effort shifts were associated with burnout. We also examined associations with important demographics and burnout.
Methods: We took data from the 2020 Council of Academic Family Medicine’s Educational Research Alliance survey of family medicine educators and practicing physicians during November 2020 through December 2020. We analyzed self-report measures of demographics, effort (clinical, teaching, research, and administrative) before and during the pandemic, COVID-19 exposure level, and rates of burnout (emotional exhaustion and depersonalization) using logistic regressions.
Results: Most participants reported no change in efforts. If changes were reported, clinical (21.6%) and administrative (24.8%) efforts tended to increase from before to during the pandemic, while teaching tended to decrease (27.7%). Increases in teaching and clinical efforts were associated with higher rates of emotional exhaustion. Higher depersonalization was associated with increased clinical efforts. Being older and working in a rural setting was associated with lower burnout, while being female was associated with higher burnout.
Conclusions: Shifts in effort across academic family physicians’ multiple roles were associated with emotional exhaustion and, to a lesser degree, depersonalization. The high rates of burnout demand additional attention from directors and administrators, especially among female physicians.

Authors: Aquino Leora , Ottney Anne , Odom Amy , Phillips Julie
Published: March 2022

Background and Objectives: Family physicians play a crucial role in addressing the opioid epidemic. We studied a novel peer-review opioid prescribing educational intervention for family medicine residents that incorporates guided instruction from an interdisciplinary care team.
Methods: We used a mixed-methods study design in the setting of a family medicine residency program in the Midwestern United States. Residents participated in small group, peer-to-peer discussions of patients chronically prescribed opioids with guidance and input from faculty, a pharmacist, and pharmacy students. Discussions followed a structured approach to evaluation based on guidelines, and written recommendations were given to the patients’ resident primary care physician (PCP). For each patient, we reviewed electronic medical records to assess whether PCPs implemented the written recommendations. We used one-way analyses of variance to determine the statistical significance of changes made. The principal investigator interviewed seven participating residents to survey their satisfaction with the curriculum and collated suggestions for improvement.
Results: Over a 3-year period, we reviewed 59 patients as part of the intervention; of these, 53 had complete records reviewed for this study. Patients’ morphine milligram equivalent dosage (MME) declined modestly (P=.035). The number and proportion of recommendations implemented was correlated with the decline in MME (P=.004 and P=.013, respectively). Interviewed residents unanimously evaluated the curriculum positively, citing that the structured approach helped align their practices with guidelines.
Conclusions: The guided peer-review intervention effectively decreased chronic opioid use among patients, and residents positively evaluated the curriculum.
Impact of risk governance on performance and capital requirements: Evidence from Egyptian banks
Authors: Ismail Tariq H. , Ahmed Eman A.
Published: March 2022

This study aims to examine the impact of banks’ risk governance (RG) on Egyptian listed banks’ performance and capital requirements as prescribed in Basel regulations. Secondary data from annual reports of all twelve banks listed on the Egyptian Stock Market (EGX) over eleven years (2010–2020) are analyzed using the dynamic ordinary least squares method; where the RG framework is presented by the proxy of the presence of chief risk officer (CRO), risk committee (RC), and audit committee (AC) characteristics. Secondary data from annual reports of all twelve banks listed on the EGX over eleven years are analyzed using the dynamic ordinary least squares method. The results support the role of banks’ RG in improving banks’ both market-based and accounting-based performance. These findings support the importance of having an independent risk committee and a powerful CRO because they can regulate banks’ increasing risk and acquire the advantages of capital requirements by investing assets in more profitable ways with low risk. This paper is one of the few empirical attempts in emerging economics to link bank RG, risk-taking behavior, performance, and capital adequacy ratio (CAR) as defined by Basel III.
Hydrological response of a headwater catchment in southeastern Brazil Part I: Patterns of rainfall-runoff and stormflow
Authors: Chittolina Mariane , Dominques Leonardo , Lobo Gré de Araújo , Rocha Humberto
Published: March 2022

Headwater basins are central for meeting water management and, in humid
tropical areas, essential to understand the baseflow, the discharge
component that maintains water availability during the dry season, and
the stormflow generated from recurrent convective clouds that can lead
to flash floods. We measured field data in a typical headwater basin and
four sub-basins, in subtropical climate region of Serra da
Mantiqueira/South-East Brazil, with a multi-instrument
hydrometeorological set (precipitation, streamflow, baseflow, stormflow,
soil moisture SM, water table depth WTD), towards providing regional
data, to our knowledge, hitherto non-existent, on hydrological response
patterns, and variation of stormflow generation with boundary conditions
and scale. Precipitation recovered in September and peaked in January
concurrently with streamflow. Baseflow responded for most of the
streamflow during the dry season and about half in the wettest months,
and peaked ahead in March, highly covariated with WTD. In contrast, SM
described a longer yearly memory, that recovered 3 months earlier than
streamflow, and depleted 2 months latter in March. The monthly scale
stormflow responded significantly to rainfall although with low
predictability. At the event scale, revealling patterns for all basins
showed thresholds of precipitation (≃ 10 mm), SM (≃45% to 57%) and WTD
≃135 cm, below which stormflow was modest. The event stormflow
coeficient (eSC) reached up a maximum of 25%, albeit with large
variance and little seasonality of the median. Estimates of eSC with
double mass and SM thresholds showed pronounced spatial and temporal
differences (3.2 to 9.6% in drier conditions and 7.7 to 15.4% wetter
conditions). Mean streamflow and runoff coefficient were quite lower at
the main basin (21% compared to about ≃32% between sub-basins), where
there possibly exists groundwater flux exportation, that discharge on a
larger spatial scale, by water exiting the basin without passing through
the surface outlet.
A Mixed Finite Volume Element Method for Time-fractional Damping Beam Vibration Problem
Authors: Wang Tongxin , Jiang Ziwen , Zhu Ailing , Yin Zhe
Published: March 2022

In this paper, by introducing two meaningful auxiliary variables, a
mixed finite volume element scheme for the time-fractional damping beam
vibration equation is established. The scheme can keep the local
conservation of physical quantity and reduce the computational cost.
Then the stability and convergence of the scheme are analyzed, and
numerical examples show its effectiveness. In the end, we test the value
of different sets of parameters to observe the influence of damping
coefficient and order of fractional derivative on the model. The results
of this paper can be used for modeling the damping of the viscoelastic

The goal of study is to determine the validation of Cognitive Engagement measure of students in the context of Pakistan. The rationale for such an investigation is that while enrollments in Pakistani higher education are increasing, passing out numbers are very low; this problem necessitates an investigation of student cognitive engagement as well as other factors. Because the Construct of Engagement arose in response to the issue of lower student turn out. The Cognitive Engagement Subscales of Attitudes towards Mathematics (ATM) were used to collect data for this study, and the convenience sampling technique was used. The sample included 528 university students from ten different universities in Karachi. The Structural Equation Modeling (SEM) approach was used for data analysis. The results revealed 21 items that were compatible with the Pakistani context, with Shallow Strategy Use (SSU) being the most endorsed subscale with a mean of 3.7. This study provided a validated instrument for future studies to determine cognitive engagement levels. Future research should look into other disciplines and the relationship with other variables.
Expected Loan Loss Provisioning: An Empirical Model
Authors: Lu Yao , Nikolaev Valeri V.
Published: March 2022

The new accounting standard requires that financial institutions estimate expected credit losses on their loan portfolios. The predictability of long-term losses, however, remains an open question. We develop a model that predicts long-term loan losses and incorporates adjustments for macroeconomic forecasts. The model combines cross-sectional predictions with a high-dimensional dynamic factor model that tracks aggregate losses over the business cycle. The model predicts long-term losses out-of-sample with significantly greater accuracy than the Harris et al. (2018) model and several other alternatives. It is also more effective at detecting bank failures. We use the model to estimate the present value of expected losses and the expected loss overhang for a given bank-quarter. The estimated present values subsume information in reported allowances and in fair value disclosures about long-term losses; the evidence is also consistent with loss overhang distorting banks' decisions. The model provides a useful benchmark to study loan loss provisioning.

Objectives

To evaluate alveolar bone remodeling following incisor retraction treatment with microimplants and to examine the relationship between crown/root distal movement and thickness/height changes of the alveolus.

Materials and Methods

A total of 24 patients (mean age, 19.29 ± 4.64 years) with bialveolar protrusion treated by incisor retraction with microimplants were included. The distances of the crown and root tip movements as well as the thickness (alveolar bone thickness [ABT]; labial, lingual, and total) and vertical level (vertical bone level [VBL]; labial and lingual) of the alveolar bone were assessed using cone-beam computed tomography images obtained before treatment (T1) and after treatment (T2). All T1 and T2 variables were compared, and further comparisons of alveolar bone changes were conducted between the two groups based on the distance of the crown (low-crown-movement and high-crown-movement groups) and root movements (low-root-movement and high-root-movement groups). To determine the correlation of the crown or root movement with the variables of alveolar bone changes, Pearson correlation coefficients were calculated.

Results

Significant differences were found in all VBL and ABT variables after treatment in both jaws but not in total ABT. Based on the crown and root movements, alveolar bone change significantly differed between the root-movement groups, whereas there was no significant difference between the crown-movement groups. In addition, root movement showed significant correlations with the variables.

Conclusions

Remarkable changes in the height and thickness of alveolar bone were found after microimplant-aided incisor retraction treatment in all groups except for total ABT. Root movement was significantly correlated with the alveolar bone changes.

Pompholyx as a Side Effect of Intravenous Immunoglobulin (IVIg)
Authors: C Doyle
Published: March 2022

A 43-year-old woman presented with a two-week history of progressive peripheral sensory neuropathy. Despite extensive investigations no cause had been identified. She has a background history of hepatitis C (treated successfully in 2018) and prior intravenous drug use. She was commenced on intravenous immunoglobulin (IVIg) at a dose of 400mg/kg daily for 5 days as a trial of treatment for her sensory peripheral neuropathy under the guidance of neurology. After receiving her third dose of IVIg she developed a discrete intensely pruritic vesicular rash on her palms and fingers bilaterally consistent with pompholyx. No other areas were affected. She was started on clobetasol proprionate 0.05% ointment once daily and advised to wash with soap substitutes and use non-fragranced emollients daily.

BackgroundIt is known that the COVID-19 pandemic and social isolation has increased anxiety, depression, and gender-based violence. However, to the best of our knowledge no studies have evaluated differences in the association between anxiety and depression symptomatology with concern about becoming infected with COVID-19, and the differential risk of suffering from gender-based violence among women with a previous mental disorder, and black women.

MethodsWe conducted a cross-sectional study among adults living in Brazil during the COVID-19 lockdown (20th June-30th August 2020). We administered an online questionnaire containing questions on socioeconomic characteristics, risk perception, confinement, health conditions, and gender-based violence. We ran two ordinal logistic regression models. In the first, we considered having a previous mental disorder and sex as the predictors, and concern about becoming infected with COVID-19 as the outcome. In the second model, we considered previous mental disorders and race as the predictors, and gender-based violence as the outcome. Depressive symptomatology and anxiety symptomatology was assessed through PHQ-9 and GAD-7, respectively.

FindingsPeople who declared that they suffered from depression had a 2% less chance of concern about becoming infected with COVID-19, while those with anxiety had an 11% higher chance. Women had 19% more chance of being very concerned about becoming infected with COVID-19, compared to men. Women with previous mental health disorders had a 34% higher chance of suffering from gender-based violence, compared to women who did not declare having a previous mental health disorder. Black women had a 54% higher chance of suffering from gender-based violence during the COVID-19 pandemic, compared to white women.

ConclusionsThis is the first study to demonstrate that black women and those with mental health problems are more likely to suffer from gender- based violence during the pandemic. These findings could be used in the preparation of protection policies focused on women in situations of major vulnerabilities, optimising interventions and enhancing resource allocation for those most in need, especially during pandemics.
