RESUMEN

Alzheimer's disease (AD) is a significant global healthcare challenge, particularly in the elderly population. This neurodegenerative disorder is characterized by impaired memory and progressive decline in cognitive function. BACE1, a transmembrane protein found in neurons, oligodendrocytes, and astrocytes, exhibits varying levels across different neural subtypes. Abnormal BACE1 activity in the brains of individuals with AD leads to the formation of beta-amyloid proteins. The complex interplay between myelin sheath formation, BACE1 activity, and beta-amyloid accumulation suggests a critical role in understanding the pathological mechanisms of AD. The primary objective of this study was to identify molecular inhibitors that target Aß. Structure-based virtual screening (SBVS) was employed using the MCULE database, which houses over 2 million chemical compounds. A total of 59 molecules were selected after the toxicity profiling. Subsequently, five compounds conforming to the Egan-Egg permeation predictive model of the ADME rules were selected and subjected to molecular docking using AutoDock Vina on the Mcule drug discovery platform. The top two ligands and the positive control, 5HA, were subjected to molecular dynamics simulation for five nanoseconds. Toxicity profiling, physiochemical properties, lipophilicity, solubility, pharmacokinetics, druglikeness, medicinal chemistry attributes, average potential energy, RMSD, RMSF, and Rg analyses were conducted to identify the ligand MCULE-9199128437-0-2 as a promising inhibitor of BACE1.

RESUMEN

During the COVID-19 pandemic, major challenges are facing pediatric cancer centers regarding access to cancer centers, continuity of the anti-cancer therapy, hospital admission, and infection protection precautions. Pediatric oncologists actively treating children with cancer from 29 cancer centers at 11 countries were asked to answer a survey from May 2020 to August 2020 either directly or through the internet. COVID-19 pandemic affected the access to pediatric cancer care in the form of difficulty in reaching the center in 22 (75.9%) centers and affection of patients' flow in 21 (72.4%) centers. Health care professionals (HCP) were infected with COVID-19 in 20 (69%) surveyed centers. Eighteen centers (62%) modified the treatment guidelines. Care of follow-up patients was provided in-hospital in 8(27.6%) centers, through telemedicine in 10 (34.5%) centers, and just delayed in 11 (38%) centers. Pediatric oncologists had different expectations about the future effects of COVID-19 on pediatric cancer care. Seventy-six percent of pediatric oncologists think the COVID-19 pandemic will increase the use of telemedicine. Fifty-five percent of pediatric oncologists think if the COVID-19 pandemic persists, we will need to change chemotherapy protocols to less myelosuppressive ones. Collaborative studies are required to prioritize pediatric cancer management during COVID-19 era.

RESUMEN

Heart failure (HF) represents an important cause of morbidity and mortality in children. It is mostly caused by congenital heart disease (CHD) and cardiomyopathy. The Ross HF classification was developed to assess severity in infants and has subsequently been modified to apply to all pediatric ages. The modified Ross classification for children provides a numeric score comparable with the New York Heart Association (NYHA) HF classification for adults. The aim of this work is to investigate the role of modified Ross score in the evaluation of children with severe lower respiratory tract infection admitted to the pediatric intensive care unit (PICU). One hundred and sixty-four children with severe LRTI admitted to the PICU were enrolled in this prospective cohort study, which was carried out at Assiut University Children Hospital, from the start of July 2021 up to the end of December 2021. Sixty patients (36.6%) of studied cases with severe LRTI admitted to PICU had HF. Out of these, 37 (61.7%) had mild HF; 17 (28.3%) had moderate HF, while six cases (10%) had severe HF according to the modified Ross score. The value of modified Ross score was significantly higher in children with heart failure with sensitivity and specificity 100% with cutoff value of 2. Admission to NICU, history of previous ventilation, and prematurity were higher in patients who developed HF. Patients with pulmonary hypertension (PH) and those with raised neutrophil lymphocyte ratio were significantly higher in the group of patients with moderate and severe degree of HF.   Conclusion: Modified Ross score is a simple clinical score which may help in assessing and predicting children with severe LRTI. What is Known: • Hear failure is common complication to lower respiratory tract infection. • Modified Ross score was used to predict and classify heart failure in adult with lower respiratory infection. What is New: • Modified Ross score found to be of value in prediction of heart failure in children with lower respiratory tract infection.

RESUMEN

Microencapsulation is a process where very minute droplets or particles of solid or liquid or gas are trapped with a polymer to isolate the internal core material from external environmental hazards. Microencapsulation is applied mostly for flavor masking, fortification, and sustained and control release. It improves palatability, absorption, and bioavailability of drugs with good conformity. Microencapsulation has been widely studied in numerous drug delivery systems for human health. The application of microcapsules in the veterinary pharmaceutical sciences is increasing day by day. The treatment systems for humans and animals are likely to be similar, but more complex in the veterinary field due to the diversity of the species, breeds, body size, biotransformation rate, and other factors associated with animal physiology. Commercially viable, economically profitable, and therapeutically effective microencapsulated vaccine, anthelmintic, antibacterial, and other therapeutics have a great demand for livestock and poultry production. Nowadays, researchers emphasize the controlled and sustained-release dosage form of drugs in the veterinary field. This paper has highlighted the microencapsulation materials, preparation techniques, characteristics, roles, and the application of microcapsules in veterinary medicine.

RESUMEN

Giant cell tumor of the tendon sheath is a slowly growing benign tumor. It usually arises from the tendon sheath and periarticular soft tissue of small joints. However, it may infrequently involve the large joints emerging around the knee, elbow, and hip joints. Giant cell tumor of the tibialis tendon sheath is rarely reported in the foot and ankle joint. Here, we report the first case in the medical literature of bilateral mirror-symmetrical giant cell tumor of the tendon sheath in the foot and ankle. A 12-year-old male presented with a bilateral and mirror-image mass on his ankles extending to the foot. It was painless but affected his gait and footwear. Staged complete resection was done first on the right then on the left side, with no recurrence after 1 year. The role of genes can be argued for this presentation and giant cell tumor's etiology, owing to the bilateralism and mirror-image presentation. Studies are needed to explore this genetic aspect and its role in management.

RESUMEN

PURPOSE: The objective of the study was to compare three nerve stimulator-guided paravertebral injections versus five injections for elderly patients undergoing inguinal hernia repair in terms of the amount of intraoperative fentanyl and propofol consumption and conversion to general anesthesia. The secondary objective was postoperative pain. METHODS: A prospective, randomized, double-blind clinical trial was performed. 200 elderly patients undergoing unilateral herniorrhaphy were randomized into two groups. Group III received three PVB injections from T12 to L2 and placebo at T11 and L3. Group V received five PVB injections from T11 to L3. RESULTS: The mean intraoperative fentanyl and propofol consumption were significantly lower in group V (4.9 ± 7.2 µg versus 20.0 ± 12.9 µg and 5.7 ± 11.6 mg versus 34.6 ± 22.9 mg, respectively, p value < 0.0001). Five patients (5.0%) in group III had failed block and were converted to general anesthesia (p value = 0.024). Group V had significantly lower pain scores compared to group III during the first three postoperative days (p value < 0.0001). CONCLUSION: The five PVB injection technique is more suitable as a sole anesthetic technique for elderly patients undergoing herniorrhaphy, since it required less intraoperative supplemental analgesia and provided lower postoperative pain scores compared to the three PVB injection technique. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT02537860.

RESUMEN

Middle East respiratory syndrome (MERS) remains a serious international public health threat. With the goal of accelerating the development of countermeasures against MERS coronavirus (MERS-CoV), funding agencies, nongovernmental organizations, and researchers across the world assembled in Riyadh, Saudi Arabia, on November 14-15, 2015, to discuss vaccine development challenges. The meeting was spearheaded by the Saudi Ministry of Health and co-organized by the International Vaccine Institute, South Korea. Accelerating the development of a preventive vaccine requires a better understanding of MERS epidemiology, transmission, and pathogenesis in humans and animals. A combination of rodent and nonhuman primate models should be considered in evaluating and developing preventive and therapeutic vaccine candidates. Dromedary camels should be considered for the development of veterinary vaccines. Several vaccine technology platforms targeting the MERS-CoV spike protein were discussed. Mechanisms to maximize investment, provide robust data, and affect public health are urgently needed.

RESUMEN

The passive bistatic radar (PBR) system can utilize the illuminator of opportunity to enhance radar capability. By utilizing the forward scattering technique and procedure into the specific mode of PBR can provide an improvement in target detection and classification. The system is known as passive Forward Scattering Radar (FSR). The passive FSR system can exploit the peculiar advantage of the enhancement in forward scatter radar cross section (FSRCS) for target detection. Thus, the aim of this paper is to show the feasibility of passive FSR for moving target detection and classification by experimental analysis and results. The signal source is coming from the latest technology of 4G Long-Term Evolution (LTE) base station. A detailed explanation on the passive FSR receiver circuit, the detection scheme and the classification algorithm are given. In addition, the proposed passive FSR circuit employs the self-mixing technique at the receiver; hence the synchronization signal from the transmitter is not required. The experimental results confirm the passive FSR system's capability for ground target detection and classification. Furthermore, this paper illustrates the first classification result in the passive FSR system. The great potential in the passive FSR system provides a new research area in passive radar that can be used for diverse remote monitoring applications.

RESUMEN

BACKGROUND: There has been a decrease in the mean gestational age at delivery worldwide mostly due to an increase in deliveries occurring at late preterm period (LPP) with a concomitant rise in the rate of morbidities among newborns delivered at this period. OBJECTIVES: To report the frequency of common short-term neonatal morbidities in infants born at LPP (between 34(0/7) and 36(6/7) weeks' gestation) and to compare these frequencies with those of full-term infants born at our institution. MATERIALS & METHODS: A descriptive cohort study (2008-2010) at Makassed General Hospital. All deliveries occurring at LPP constituted the study group (n = 361), while births at or beyond 37 weeks' gestation were considered as controls (n = 2814). RESULTS: The average rate of deliveries in LPP was 11.4% for the entire study period. The rate of Neonatal Intensive Care Unit admissions, respiratory morbidities, sepsis, jaundice, hypothermia, hypoglycemia and overall neonatal morbidity were all significantly higher in LPP infants when compared to those at term (p-value < 0.013). CONCLUSION: In our cohort of Lebanese newborns delivered at LPP, significantly higher morbidities were encountered when compared to full-term newborns. Every possible effort should be exerted to avoid elective deliveries during LPP in order to curb the incidence of neonatal morbidities.

RESUMEN

BACKGROUND: Neck pain (NP) is often associated with upper limb disability (ULD). A clinically feasible measure to evaluate ULD in NP patients is necessary. The Single Arm Military Press (SAMP) is a ULD performance-based measure, specifically for NP patients. The validity of the SAMP in patients is still unknown. OBJECTIVE: To explore the construct validity (hypotheses testing) of the SAMP in NP patients. METHODS: A total of 210 NP patients and 81 controls were recruited. The SAMP; Disability of the Arm, Shoulder, and Hand (DASH); and Neck Disability Index (NDI) were completed at baseline and 4-7 days later. The Visual Analogue Scale (VAS) was used to measure NP and ULD severity pre-testing in both occasions. Patients were divided into 4-subgroups based on their NDI score. Convergent validity was examined using Pearson correlation. The t-test and analysis of variance (ANOVA) were used to evaluate discriminant and known groups' validity. To determine SAMP cut-off scores, the sensitivity and specificity were explored. RESULTS: A negative correlation between the SAMP and DASH/NDI scores was found in the patient group (r = -0.91 and -0.87, p < 0.01). The t-test revealed substantial differences (t = -23.96) in score between patients and controls. Also, ANOVA revealed substantial differences (f = 20.86) between the patients' subgroups. The area under the curve (AUC) for patients and controls exceeded 0.90 when sensitivity and specificity were at equal importance. CONCLUSION: The SAMP can distinguish between NP patients and controls, and between different NP disability levels. The responsiveness of the SAMP needs to be investigated.

RESUMEN

OBJECTIVE: Brain metastasis (BM) from bone and soft tissue sarcomas (STS) is very rare and mostly predicts dismal prognosis. Owing to its' rarity, data on optimal therapy including surgical management, chemotherapy, and radiotherapy is scarce. We sought to assess the prevalence, disease characteristics, and outcomes of BM in bone and STS patients treated at a single institution. METHODS: A retrospective chart review was performed for consecutive bone and STS patients treated at King Hussein Cancer Center from 2007 to 2020. Patients with BM were identified. Survival was estimated by the Kaplan-Meier method. Factors of possible effect on OS was examined in univariate analysis. Survival comparisons were carried out by the log-rank test. RESULTS: A total of 1,548 bone and STS patients were treated at our center during the eligibility period. We identified 18 patients (1.1%) who had BM at initial presentation (n = 16, 1.0%) or during follow up (n = 2; 0.1%). Fourteen patients (77.8%) were male. The median age was 29.5 years (range: 0.1-60 years). The primary tumor was most commonly located in the extremities (61%). Ten different histopathological subtypes were encountered; Ewing sarcoma (ES) was the most common (n = 4; 28%). Twelve patients (67%) had lung metastasis as the first site of metastatic disease. BM was detected at a median time of 12 months following sarcoma diagnosis (range: 1-71 months). A total of 10 patients (56%) had solitary metastasis and 4 patients (22.2%) had hemorrhagic metastasis. The most common location of brain metastatic lesions was the occipital lobe (n = 4; 22.2%). Thirteen patients received treatment for metastatic brain sarcoma. The most common treatment modality was radiotherapy, received by a total of 10 patients (55.5%), followed by surgical intervention performed in a total of 5 patients (27.7%), The other treatment modalities included combined chemo-radiotherapy (n = 2), targeted therapy plus chemotherapy, and targeted therapy plus radiotherapy (n = 1, each). At a median follow up of 10 months following detection of BM, the median OS was 4.0 months; (95% CI: 2.54-5.46). We did not identify any factor that influenced OS in univariate analysis. CONCLUSION: Sarcoma BM is exceedingly rare and herald's dismal prognosis. ES was a major histological subtype accounting for BM metastasis in our series.

RESUMEN

Camurati-Engelmann disease (CED) is a rare disorder caused by activating mutations in the TGF-ß1 gene and characterized by hyperostosis of long bones and bone dysplasia. We describe a case of an adolescent with CED and moderate-severe Crohn Disease (CD). Infliximab improved gastrointestinal symptoms but was associated with worsening CED-associated bone pain. Clinical remission was successfully achieved with dual biologic therapy that included vedolizumab and ustekinumab. Possible reasons for this patient's clinical response are advanced and include speculation about the complex role of TGF-ß1 signaling in the etiology of both CED and CD.

RESUMEN

BACKGROUND: Several anesthetic techniques have been used for pilonidal sinus surgery such as general, spinal, and local anesthesia infiltration. However, the most effective technique remains controversial. The aim of this study was to assess the effectiveness of sacrococcygeal local anesthesia for complicated pilonidal cysts in terms of postoperative analgesic consumption. METHODS: This was a retrospective cohort study conducted by collecting data from medical records for male patients who underwent pilonidal surgery using sacrococcygeal local anesthesia from 2008 to 2018. Patients' demographics, operative data, and postoperative outcomes such as pain, nausea, as well as analgesic consumption at 0 and 3 hours were analyzed. Pain scores at rest and upon pressure were recorded using the Visual Analogue Scale. The length of complicated pilonidal sinus was considered to be greater than or equal to 7 cm with multiple openings. RESULTS: A total of 394 patients were included in the study, 173 patients (43.9%) had complicated cysts while 221 patients (56.1%) had uncomplicated cysts. The majority of patients were males (85.5% vs. 76.9% in the complicated and uncomplicated groups respectively). Patients' weight was significantly higher in the complicated cyst group (87.12 ± 17.07 vs. 82.43 ± 20.30 kg, P value = 0.02). Around 41% of the patients in the complicated group were obese (body mass index ≥ 30 kg/m^2) compared to 32.0% of the patients in the uncomplicated group. Mean arterial pressure and heart rate at baseline, intraoperatively and at the end of the operation were similar between the two groups. Pain scores at rest and upon pressure were low in both groups. Analgesic consumption was similar between the two groups. Eight patients (4.6%) in the complicated group required acetaminophen at 0 hour compared to 6 patients (2.7%) in the uncomplicated group. Three patients (1.7%) received ketoprofen at 0 hour in the complicated group and 3 patients (1.4%) in the other group. Three patients, 2 (1.2%) in the complicated group and 1 (0.5%) in the second group required tramadol hydrochloride. CONCLUSIONS: Sacrococcygeal local anesthetic technique for complex pilonidal sinus surgery provided intra-operative hemodynamic stability as well as low post-operative pain and analgesic consumption.

RESUMEN

Bullying is defined as unpleasant behavior that causes someone to feel disturbed or embarrassed, affecting their self-esteem. Based on this premise, we set out to investigate bullying among Syrian graduate medical education residents and fellows, estimate its prevalence among specific subgroups, and give recommendations to help validate the findings and enhance the graduate medical education training experience. A sample of 278 residents and fellows in Syrian graduate medical school were recruited for the study in a national cross-sectional survey, with 276 participants completing a Bullying survey in 2021 and two people refusing to participate. Participants in the survey were asked to provide basic demographic and programming information and three general Bullying and 20 specific bullying behavior items. Differences across groups were compared for demographic and programmatic stratifications. About 51% of participants had experienced one or more bullying behaviors, 69% said they had been bullied, and 87% said they had witnessed Bullying. Residents and supervisor-attendings were the most common sources of perceived Bullying (~67 and 62%, respectively), followed by patients (58%), nurses (46%), and pharmacists (46%) (33%). More specific bullying behaviors have been recorded by female Arabic Syrians who are shorter than 5'8, have a body mass index (BMI) of 25, and are 30 years old or younger who were -compared to males- more likely to report attempts to minimize and devalue work (55 vs. 34%, P ≤ 0.01) and criticism and work monitoring (56 vs. 33%, P ≤ 0.01). In addition, general medical graduates and PGY-2-PGY-6 respondents reported more specific bullying behaviors than private medical graduates and post-graduate participants in the first year (PGY 1), respectively. For example, a significant difference is noticed when reporting unreasonable pressure to perform work (83 vs. 6%, P ≤ 0.01). Except for physical violence, which does not differ statistically between groups, most bullying behaviors were reported by participants with statistically significant differences between study groups-many residents and fellows in Syria's graduate medical school system report being bullied. Anti-bullying rules and a multidisciplinary strategy including all players in the medical system are essential to eradicating these pervasive practices in healthcare.

RESUMEN

PURPOSES: To determine the incidence, obstetrical, and fetal complication rates of intrahepatic cholestasis of pregnancy (ICP) in patients managed expectantly to 40-weeks gestation. METHODS: In a prospective cohort study conducted between February 2008 and January 2010, a total of 21,960 pregnant women in Qassim Region of Saudi Arabia were screened for ICP using specific criteria for diagnosis. The course of pregnancy was monitored to 40-weeks gestation or spontaneous onset of labor, whichever comes first. The measured outcomes were compared with a cross-matched group of healthy pregnant women. Continuous variables were analyzed with t test, while χ(2) test was used for comparing percentages. RESULTS: The incidence of ICP was 0.35% (76/21,960). There was no significant difference between groups in gestational age at delivery, preterm labor, intrauterine fetal death, cesarean section, or respiratory distress syndrome. There was significantly higher intrapartum non-reassuring fetal heart rate patterns and meconium-stained amniotic fluid in ICP group (P < 0.01 and <0.0001, respectively). CONCLUSIONS: The incidence of ICP in this region is low compared to worldwide range. Expectant management to 40-weeks gestation is associated with obstetrical and fetal outcomes comparable to normal pregnancy; however, intrapartum fetal asphyxia is more likely.

RESUMEN

Aloe vera is reputed to have medicinal properties. For centuries, it has been used for an array of ailments such as mild fever, wounds and burns, gastrointestinal disorders, diabetes, sexual vitality and fertility problems to cancer, immune modulation, AIDS and various skin infections. In present study, antibacterial activity of aloe vera gel extracts was tested against some common skin infection pathogens, that is, Escherichia coli, Shigella, Salmonella spp. and Staphylococcus aureus all were recorded positive. Antibiotic resistance and susceptibility pattern of above isolates were also studied against 10 clinically significant antibiotics (ampicillin [AMC], amoxicillin, augmentin, cefotaxime, ceftazidime [CAZ], cefuroxime [CXM], ciprofloxaci, tetracycline, cefpodoxime and imipenem). AMC and CXM were found to be most effective antibiotic followed by CXM with highest efficacy against Gram-negative bacteria. In case of CAZ showed highest efficacy was showed against Gram-positive bacteria. Aloe vera leave gel was extracted with four different solvent-like aloe vera leaf extract, root extract, leaf ethanol extract and root ethanol extract; however, Gram-negative as well Gram-positive isolates was found highest susceptibility with aloe leaf and aloe root ethanol extract. Moderate sensitivity observed with aloe leaf extract and aloe root extract against both Gram-positive as well as Gram-negative bacterial isolates. This result showed that ethanol extracts of aloe vera both leaf and root can be used alongside conventional antibiotics to fight agents of infections that are so prevalent in the skin infection.

RESUMEN

BACKGROUND: Routine utilisation of outcome measures (OMs) is an integral part of physiotherapy rehabilitation when managing non-specific neck pain (NSNP). Numerous relevant OMs exist; however, the extent to which OMs are used by physiotherapists in the UK for NSNP is unknown. OBJECTIVE: To determine current utilisation patterns of OMs in UK physiotherapy practice when managing NSNP. METHODS: An online web-based survey instrument was developed and physiotherapists were invited to participate if they were currently practicing in the UK and had some experience of managing patients with neck pain. Logistic regression analyses using the generalised linear models was carried out to identify characteristics associated with OMs utilisation. RESULTS: A total of 2101 surveys were completed. One-third of the respondents reported not using OMs when managing NSNP. Lack of time and clear guidance about the suitability of available OMs were the most commonly reported reasons. A majority of the two-thirds of those who reported using OMs were consistently using pain and range of motion rating measures. Physical/functional limitations, psychological distress, and quality of life constructs, which are frequently associated with NSNP, were rarely measured. Years of practice (p = 0.000), nation (p = 0.019) and proportion of patients with neck pain (p = 0.034) variables were found to be independently associated with frequent use of OMs. CONCLUSION: This survey established the poor integration of OMs in the UK when managing NSNP. Further attention is required to identify or develop OMs which are feasible for use in busy clinical practice and to market them more effectively to physiotherapists.

RESUMEN

AIM: Myxoid liposarcoma (MLS) is a rare malignant soft-tissue neoplasm in which brain metastasis is still considered rare. We present a case of MLS brain metastasis and review of the literature. CASE PRESENTATION: A 24-year-old male patient presented with headache, decreased level of consciousness and vomiting. He was treated for distal right thigh MLS 2-years ago. Imaging studies of the brain showed a left frontal intracranial mass. The patient underwent surgical resection followed by stereotactic radiosurgery. The histopathological study revealed metastatic myxoid/roundcell liposarcoma infiltrating the bone and peripheral margins. CONCLUSION: Treatment options for MLS usually includes surgical resection and adjuvant radiotherapy. A case-by-case based multidisciplinary approach is recommended for the management of similar cases.

RESUMEN

ABSTRACT: Health care employees are the front liners whom are directly involved in the management of COVID-19 at high risk of developing psychological distress and other mental health illness. We aim to assess the burden of depression during this pandemic on health care employees treating COVID-19 in Saudi Arabia. We also will shed the light on the best solutions of how to encounter depression.A cross-sectional, hospital-based survey conducted via a region-stratified, 2-stage cluster sample was conducted for 554 participants in >15 hospitals from April 29, 2020, to June 30, 2020. Depression is measured using the established PHQ9 score system. We grade PHQ9 depression scores as: normal, 0 to 4, mild, 5 to 9, significant (moderate or severe), 10 to 27. χ2/Fisher exact test was used; significant association between level of depression and survey characteristics were made. P value <0.05 was considered statistically significant.A total of 554 participants completed the survey. A total of 18.9% (n = 105) were aged <29 years, 51.2% (n = 284) were between 30 to 39 years and female represent 70% of all participants. Of all participants, 53.7% (n = 298) were nurses, and 38.6% (n = 214) were physicians; 68.5% (n = 380) worked in central area hospitals in Saudi Arabia. No significant (P = .432, 95% confidence interval [CI]) association was observed between sex and depression classifications. However, female had high proportion of significant depression 75.0% (n = 76) was observed as compared to male 24.8% (n = 25). Depression was significant in Saudis 61.4% (n = 62) (P < .001, 95% CI) and medical staff who encountered corona patients 51.5% (n = 52) (P < .002, 95% CI). Hospital preparedness associated with more freedom of depression symptoms 69.1% (n = 199/288) (P < .001, 95% CI).Frontline young health care workers especially physician in Saudi Arabia reported a high rate of depression symptoms. Countermeasures for health care workers represent a key component for the mental and physical well-being as part of public health measures during this pandemic. Attention to hospital preparedness and adequacy of personal protective equipment contributed to milder depression symptoms. Further studies need to be conducted on crisis management and depression.
