Background Obesity is a risk factor for gallstone formation, which can be exacerbated by bariatric surgery-induced rapid weight loss. Current guidelines do not recommend concomitant cholecystectomy (CC) for asymptomatic gallstones during the bariatric surgery procedure. However, long-term follow-up studies have shown that the incidence of post-bariatric surgery symptomatic gallstones necessitating therapeutic cholecystectomy increases to 40%. Therefore, some surgeons advocate simultaneous cholecystectomy during the bariatric surgery for asymptomatic individuals. This study aims to evaluate the safety of performing cholecystectomy for asymptomatic gallstones during the bariatric procedure. Methods Data from a consecutive series of patients that underwent primary laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LRYGB) or conversion of LSG to a LRYGB with or without concomitant cholecystectomy for asymptomatic gallstones between Jan 2010 and Dec 2017 were retrieved from the database. The primary endpoint was the complication rate. Secondary endpoints were the surgical operating room time (ORT) and the length of hospital stay (LOS). Results Out of the 2828 patients who were included, 120 patients underwent a concomitant cholecystectomy during their bariatric procedure (LSG or LRYGB) for asymptomatic gallbladder stones and were compared to the 2708 remaining patients who only had bariatric surgery. None of the concomitant cholecystectomy patients developed a gallbladder-related complication. There was no significant increase in the rate of minor or major complications between the CC groups and the non-CC groups (LSG: 6.7% vs. 3.2%, p=0.132; LRYGB: 0% vs. 2.3%, p =0.55; and conversion of LSG to LRYGB: 20% vs. 7.1%, p = 0.125, respectively). In addition, there was no significant increase in the length of hospital stay (1.85 ±4.19 days vs. 2.24 ±1.82, p=0.404) for LSG group and (1.75 ±2.0 vs. 2.3 ±2.1, p=0.179) for LRYGB group. Adding the cholecystectomy to the bariatric procedure only added an average of 23 min (min) (27 min when added to LSG and 18 min when added to LRYGB). Conclusion As one of the largest series reviewing concomitant cholecystectomy in bariatric surgery, this study showed that in skilled laparoscopic bariatric surgical hands, concomitant cholecystectomy during bariatric surgery is safe and prevents potential future gallstone-related complications. Long-term large prospective randomized trials are needed to further clarify the recommendation of prophylactic concomitant cholecystectomy during bariatric surgery.

Inhibition of luteinizing hormone (LH) by gonadotropin releasing hormone (GnRH) antagonist may lead to suboptimal response during ovarian stimulation. In addition, several studies suggest that low level of LH is associated with lowered fertilization and implantation rate and increased early pregnancy loss rate. The aim of this study is to study the effect of adding low dose human chorionic gonadotropin (hCG - 200 IU), as an LH supplement, to recombinant follicle stimulating hormone (rFSH) in a GnRH antagonist cycles in women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment. Sixty-three infertile women undergoing IVF were randomly divided into two groups. One group was stimulated with the conventional stimulation protocol (rFSH alone), while the second group received 200 IU hCG in addition to rFSH in the late follicular phase (hCG + rFSH). Both groups' results including pregnancy rate, total dose of rFSH required, duration of stimulation, endometrial thickness, oocytes and embryos characteristic, serum hormone levels (Testosterone, Estradiol, Progesterone, and LH) and level of epidermal growth factor (EGF) were compared. The results show that pregnancy rate among the group of women who received the low dose hCG was higher than those who did not receive hCG. However, this difference did not reach statistical significance. Furthermore, other cycle outcomes and hormonal values were comparable between the two stimulation protocols.

BACKGROUND: Due to the rise in the number of deaths, the hepatitis C virus remains a public health issue worldwide. During the recovery period, cytokines are known as indicators of chronic liver infection. AIM: In this study, immunological parameters were measured and calculated in chronic hemodialysis patients after more than 6 months of drug administration. METHODS: We have picked 60 patients with hemodialysis who are anti-HCV positive. ELISA and the calculation of alkaline phosphatase (ALP) were used to evaluate IP-10 and IFN-γ. RESULTS: A substantial association between variables and infected cases was found. No worth was considered for genders or age categories. CONCLUSIONS: The serum IP-10 level can be a warning primarily for patients who have taken a variety of prescriptions intermittently. In both the RPT and RST cohorts, IFN-γ serum levels are usually elevated. Serum level ALP is not a particular chronic HCV predictor.

A cross-sectional observational study was conducted on 213 patients with COVID-19 who did not have a clinical history of diabetes at hospital admission. One week after hospitalization, they were stratified by random blood glucose levels. It was found that 25.4, 22.5 and 52.1% of COVID-19 patients were classified as normoglycemia, prediabetes and diabetes, respectively. The study indicated that diabetes may be a risk factor for COVID-19 or the disease may be associated with an increased risk of developing diabetes.

Durvalumab (IMFINZI®), a fully human monoclonal antibody against programmed cell death-ligand 1 (PD-L1), is approved for use in combination with etoposide and either carboplatin or cisplatin for the first-line treatment of patients with extensive-stage small cell lung cancer (ES-SCLC). In the pivotal phase III CASPIAN trial in previously untreated adults with ES-SCLC, the addition of durvalumab to chemotherapy for up to 4 cycles followed by maintenance durvalumab was associated with a significantly longer overall survival and a favourable hazard ratio for progression-free survival compared with chemotherapy alone for up to 6 cycles. A higher proportion of patients in the durvalumab plus chemotherapy group had an objective response compared with the chemotherapy alone group. The efficacy of durvalumab was also sustained with longer follow-up. Durvalumab in combination with etoposide and either carboplatin or cisplatin had a manageable tolerability profile in patients with ES-SCLC. Given the available evidence, durvalumab in combination with etoposide and either carboplatin or cisplatin represents a valuable treatment option for the first-line treatment of patients with ES-SCLC, and is an accepted standard of care option in this setting. Supplementary Information The online version contains supplementary material available at 10.1007/s11523-021-00843-0., Plain Language Summary Small cell lung cancer (SCLC) is the most aggressive form of lung cancer; extensive-stage (ES) disease, which accounts for about two-thirds of all SCLC, is associated with high relapse rates and a poor prognosis. Expression of programmed cell death-ligand 1 (PD-L1) on both tumour cells and tumour-associated immune cells is an adaptive immune response that helps tumour cells avoid detection and subsequent elimination by the immune system. Durvalumab (IMFINZI®) is a fully human monoclonal antibody against PD-L1, which blocks the interaction of PD-L1 with its receptors, thus enhancing anti-tumour immune responses. When used in combination with chemotherapy (etoposide and either carboplatin or cisplatin) in adults with untreated ES-SCLC, durvalumab prolonged overall survival compared with chemotherapy alone; the improvements in overall survival were also maintained with additional follow-up. The tolerability profile of durvalumab in combination with chemotherapy was manageable in patients with ES-SCLC. Durvalumab in combination with chemotherapy is an effective and valuable treatment option for previously untreated patients with ES-SCLC.

Metyrapone (Metopirone®), a pyridine derivative, is a useful treatment option for the management of patients with endogenous Cushing’s syndrome, based on evidence from more than six decades of its use in clinical practice, prospective and retrospective studies, as well as case reports. Metyrapone is associated with a rapid onset of action and is effective in reducing cortisol levels and improving clinical and/or biochemical features and cortisol-related comorbidities of Cushing’s syndrome. The efficacy of metyrapone was demonstrated in all aetiologies of the condition, when used in a range of clinical settings (including presurgery treatment and when used in combination with other drugs) and in the short and long term. Metyrapone is generally well tolerated when used in the treatment of patients with endogenous Cushing’s syndrome, with gastrointestinal adverse events being the most commonly reported. Endogenous Cushing’s syndrome is a rare disease, resulting from cortisol hypersecretion, and is associated with substantial morbidity and mortality. Surgery is the mainstay treatment for the majority of patients with Cushing’s syndrome; however, medical therapy is increasingly being used, particularly when surgery is not indicated or is unsuccessful, or while waiting for radiotherapy to be effective. Oral metyrapone (Metopirone®), a pyridine derivative, is approved for the management of endogenous Cushing’s syndrome in the EU. Evidence for the efficacy of metyrapone in the treatment of Cushing’s syndrome has been demonstrated in prospective and retrospective studies. Metyrapone has a rapid onset of action (≈ 2 h), reduces cortisol levels, improves the clinical and/or biochemical features and cortisol-related comorbidities of the disease, and demonstrates sustained efficacy in the long term; the efficacy of metyrapone is evident in a range of clinical settings. Metyrapone is generally well tolerated in patients with endogenous Cushing’s syndrome. Given its efficacy and tolerability profile, metyrapone is a useful treatment option for the management of patients with endogenous Cushing’s syndrome.

Objectives To describe the epidemiological characteristics of the first 69,382 patients with COVID-19 infection in Oman. Methods A retrospective case series study of patients diagnosed with SARS-CoV-2 infection in Oman from 24 February to 23 July 2020. The data were obtained from the National surveillance COVID-19 network. Results The overall mean age of patients was 34 (± 14) years, 74% (n = 51,391) were males, 40,859 (59%) were Omani citizens, and 28,523 (41%) were foreign-born individuals. The most common symptoms at presentation were fever 50% (n = 34,600), cough 46% (n = 32,062), sore throat 46% (n = 31,953) and shortness of breath (SOB) 35% (n = 24,567). Overall, 8,960 (12.9%) patients required hospitalization with 1189 (13.3%) individuals requiring admission to the intensive care unit (ICU) and mechanical ventilation (MV). Patients hospitalized with COVID-19 infection were mostly Omani nationals and males between 30 and 39 years old (p n = 359) with rates of 9.4 (n = 278) and 4.8 (n = 81) deaths per 100,000 population in Omani nationals and foreign-born individuals, respectively. Females hospitalized with COVID-19 had a mean age of 64 (± 18) years versus a mean age of 55 (± 17) years in males. Mean age of patients with COVID-19-related mortality was 58 (± 18) years with significant differences in mean age between females and males 64 (± 18) versus 55 (± 17) years, respectively. Conclusions Young Omani males accounted for the highest incidence of COVID-19 infection and hospitalization, while mortality rates were higher among males and the older age (> 50 years). Identifying the epidemiological characteristics and outcomes of COVID-19-infected patients is essential for developing targeted intervention strategies and preparing for the resurgence of anticipated second and third waves of this pandemic.

Background: Depression during pregnancy occurs more often than most people realize. Early detection of depression during pregnancy is critical because depression can adversely affect birth outcome and neonatal health. Mental health care during pregnancy is a serious public health issue. Objectives: to estimate the prevalence of antepartum depression and its effects on pregnancy outcome; among pregnant women in the last trimester,living in rural Egypt. Methods: the first part of the study was cross sectional; to assess the prevalence of antepartum depression. This was followed by a prospective part to detect the effects of antepartum depression on the outcome of pregnancy. The sample size was 300 consented women. A structured interview questionnaire was designed including socio-demographic and economic data, obstetric history, and neonatal information. Hamilton Rating Scale was used to detect the prevalence and level of Depression Results: 68.7% of sampled women suffered from antepartum depression. The incidence of low birth weight was (4%), and about one fifth of babies were admitted in NICU in the first month. Death in first month of life was (3%). The only significant predictor of unfavorable birth outcome using logistic regression was depression level. Females with severe depression were 9.43 at higher risk to have unfavorable birth outcome than normal ones. Also females with moderate depression had 1.4 higher risk to have unfavorable birth outcome than females without depression. Conclusion: (68.7%) of women suffered from depression during pregnancy. Increasing level of depression was significantly associated with adverse birth outcome. Key Words: depression, pregnancy, mental health, ANC, neonatal health.

Encorafenib (Braftovi®) is an oral small molecule BRAF inhibitor used in combination with cetuximab for the treatment of adult patients with metastatic colorectal cancer (mCRC) with a BRAF V600E mutation, who have received prior systemic therapy. In a clinical trial in adults with BRAF V600E-mutated mCRC who had disease progression after one or two previous regimens (BEACON CRC), encorafenib plus cetuximab was associated with a significantly longer median overall survival (OS), a higher objective response rate (ORR) and longer median progression-free survival (PFS), compared with standard therapy. Encorafenib plus cetuximab had a manageable tolerability profile in BEACON CRC. Current evidence suggests that encorafenib plus cetuximab combination therapy is an important targeted regimen for patients with mCRC and a BRAF V600E mutation who have received prior therapy.

Objectives: The present research aimed to find an association between infection by Helicobacter pylori and vitamin D deficiency in type 2 diabetes mellitus among Iraqi individuals attending Al-Yarmouk Teaching Hospital. Methods: According to fasting blood glucose, the samples were divided into a non-diabetic group with ten diabetic individuals and a diabetic group with thirty individuals. Results: The anti-H. Pylori (IgG) levels were 86.77± 58.62 NTU/µL in diabetic patients compared with 10.12 ± 7.40 NTU/µL in non- diabetic group. Vitamin D levels were decreased significantly in infected patients compared to non-infected subjects. Conclusion: The H pylori-infected patients have recorded the lowest level of vitamin D than non-infected individuals.

The effect of fabrics on common atopic dermatitis (AD) is significant, but studies are sparse. Current evidence suggests ubiquitous cotton and silk do not exacerbate AD; like superfine wool, they may improve it. Coarse and/or occlusive fabrics like wool, nylon, acetate and most polyesters are not recommended. Newer manufactured options like lyocell and antimicrobial silver-impregnated textiles are promising. All these fabrics need further study in AD.

Kainic acid (KA) induced epileptic seizures in mice is a commonly used experimental model of epilepsy. Previous studies have suggested the roles of various neurotransmitters and oxidative stress in KA-induced seizures. An important role of hypothyroidism has also been suggested in epilepsy. Thiamazole (TZ) is an anti-hyperthyroid drug with antioxidant property. This study reports the effect of TZ on KA-induced epileptic seizures in mice, produced by intraperitoneal (IP) injection of KA (18 mg/kg). Prior to KA injection, the animals were treated with TZ (12.5, 25 and 50 mg/kg IP). Our results showed that in KA alone group, about half of the animals developed seizures. Pre-treatment of mice with TZ significantly increased the frequency of seizures in dose-dependent manner. Administration of TZ significantly reduced the latency time and aggravated the severity of seizures. TZ also increased the mortality in KA-treated mice. Striatal dopamine and serotonin levels were markedly increased in KA alone treated mice, which were not significantly affected by TZ treatment. Among the indices of oxidative stress, we observed a significant reduction in cerebral vitamin E whereas the levels of cerebral malondialdehyde and conjugated dienes were significantly increased in animals with high severity of seizures. In conclusion, TZ potentiated the frequency and severity of experimental seizure in mice. There is a possibility of altered metabolism of KA in presence of TZ that might have potentiated the toxicity of KA. These findings suggest a caution while administering anti-hyperthyroid drugs in epileptic seizures.

Communities play an important and active role in preventing and controlling the spread of coronavirus disease (COVID-19) Reduction of COVID-19-related barriers and threats perceived by the public should be the top priority in promoting positive preventive behaviors among people This cross-sectional study aimed at identifying the barriers and threats perceived by public university students in the southwestern part of Saudi Arabia during the COVID-19 pandemic The students were recruited through a snowball sampling technique, and data were collected using a web-based questionnaire Data on socio-demographic aspects, perceived barriers, and perceived threats were collected Perceived barriers were estimated using the Health Belief Model (HBM) questionnaire, and perceived threats were estimated using the patient threat perceptions in the emergency department scale This study was conducted between March and June 2020 Approximately 50% of the study participants had a high level of perceived barriers and a moderate level of total perceived threats Notable factors associated with participants' perceived barriers and threats were age, college type, and monthly income Perceived barriers, participants' residence location, and sex were also significantly related to each other Moreover, perceived barriers were significantly correlated with perceived threats COVID-19-related perceived barriers and threats ranged from a moderate level to a high level among most of the participating students Perceived barriers were associated with some of the demographic variables The findings from this study may help the government in formulating strategies for planning interventions to reduce COVID-19 pandemic propagation [ABSTRACT FROM AUTHOR] Copyright of Journal of Pure & Applied Microbiology is the property of Dr M N Khan and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission However, users may print, download, or email articles for individual use This abstract may be abridged No warranty is given about the accuracy of the copy Users should refer to the original published version of the material for the full abstract (Copyright applies to all Abstracts )

Biotherapeutics are highly efficacious, but the pain and inconvenience of chronic injections lead to poor patient compliance and compromise effective disease management. Despite innumerable attempts, oral delivery of biotherapeutics remains unsuccessful due to their degradation in the gastrointestinal (GI) environment and poor intestinal absorption. We have developed an orally ingestible robotic pill (RP) for drug delivery, which protects the biotherapeutic drug payload from digestion in the GI tract and auto-injects it into the wall of the small intestine as a safe, pain-free injection since the intestines are insensate to sharp stimuli. The payload is delivered upon inflation of a balloon folded within the RP, which deflates immediately after drug delivery. Here we present results from two clinical studies demonstrating the safety, tolerability and performance of the RP in healthy humans. In the first study, three versions of the RP (A, B and C) were evaluated, which were identical in all respects except for the diameter of the balloon. The RP successfully delivered a biotherapeutic (octreotide) in 3 out of 12 subjects in group A, 10 out of 20 subjects in group B and 16 out of 20 subjects in group C, with a mean bioavailability of 65 ± 9% (based on successful drug deliveries in groups A and B). Thus, reliability of drug delivery with the RP ranged from 25 to 80%, with success rate directly related to balloon size. In a separate study, the deployment of the RP was unaffected by fed or fasting conditions suggesting that the RP may be taken with or without food. These promising clinical data suggest that biotherapeutics currently administered parenterally may be safely and reliably delivered via this versatile, orally ingestible drug delivery platform.

Background The prevalence of diagnosed chronic hepatitis C virus (HCV) infection among pregnant women in the Netherlands is 0.26%, yet many cases remain undiagnosed. HCV screening and treatment of pregnant HCV carriers could reduce the burden of disease and limit vertical transmission from mother to child. We assessed the impact of HCV screening and subsequent treatment with new direct-acting antivirals (DAAs) among pregnant women in the Netherlands. Methods An HCV natural history Markov transition state model was developed, to evaluate the public-health and economic impact of HCV screening and treatment. Besides all 179,000 pregnant women in the Netherlands (cohort 1), we modelled 3 further cohorts: all 79,000 first-time pregnant women (cohort 2), 33,000 pregnant migrant women (cohort 3) and 16,000 first-time pregnant migrant women (cohort 4). Each cohort was analyzed in various scenarios: i no intervention, i.e., the current practice, ii screen-and-treat, i.e., the most extensive approach involving treatment of all individuals found HCV-positive, and iii screen-and-treat/monitor, i.e., a strategy involving treatment of symptomatic (F1–F4) patients and follow-up of asymptomatic (F0) HCV carriers with subsequent treatment only at progression. Results For all cohorts, comparison between scenarios (ii) and (i) resulted in ICERs between €9,306 and €10,173 per QALY gained and 5 year budget impacts varying between €6,283,830 and €19,220,405. For all cohorts, comparison between scenarios (iii) and (i) resulted in ICERs between €1,739 and €2,749 per QALY gained and budget impacts varying between €1,468,670 and €5,607,556. For all cohorts, the ICERs (scenario iii versus ii) involved in delayed treatment of asymptomatic (F0) HCV carriers varied between €56,607 and €56,892, well above the willingness-to-pay (WTP) threshold of €20,000 per QALY gained and even above a threshold of €50,000 per QALY gained. Conclusion Universal screening for HCV among all pregnant women in the Netherlands is cost-effective. However, it would be reasonable to consider smaller risk groups in view of the budget impact of the intervention.

Introduction: There is paucity of data regarding change in arachnoid cyst (AC) volume following surgery. This study aimed at investigating the clinical outcome of ACs and applying 2 volumetric methods for determination of their volume change post microsurgical fenestration. Methods: Twenty-one ACs in 20 patients that underwent microsurgical fenestration were analyzed using 2 volumetric methods; the modified McDonald equation and the picture archiving and communication (PAC) system-based method. Patients were followed up for 23 ± 40.3 months. Results: The majority of the patients (13 or 65%) were children. Preoperative symptoms in children were mainly seizures and less commonly headache. Of the 20 patients, 12 (60%) had complete resolution of their preoperative symptoms with 8 (40.0%) showing partial improvement. Volumetric studies showed a mean reduction in AC size of 73.7% in children and 64.4% in adults using the PAC system versus 67.9% in children and 70.5% in adults using the modified McDonald equation method. There was no correlation between the percentage decrease in AC volume post surgery and degree of symptom improvement (49.2 ± 34.3% in patients with complete vs. 60.9 ± 40.3% in patients with only partial resolution of symptoms, p = 0.57). Discussion/Conclusion: Microsurgical fenestration is an effective approach for ACs with an excellent clinical outcome apparent in the complete or partial improvement of symptoms in all patients. Volumetric estimates of ACs and their change following surgery are feasible using the modified McDonald or PAC system methods. However, there is no correlation between the percentage decrease in AC volume after surgery and degree of clinical improvement.

Objectives: Colorectal cancer (CRC) is the third most prevalent malignant neoplasm. Genetic variations in the xenobiotic metabolising cytochrome enzymes. Family 1 Subfamily A Member 1 (CYP1A1) and Family 1 Subfamily B Member 1 (CYP1B1) might play a role in cancer pathogenesis and prognosis. The aim of this work is to determine the frequency of Single Nucleotide Polymorphisms (SNPs) in CYP1A1 (rs1048943, Ile462VaI and rs4646903/MSP1) and CYP1B1 (rs1056836, Leu432Val) genes in patients with CRC cancer. It was also an attempt to identify the association between SNPs and CRC and its stage and grade at diagnosis. Methods: This case-control study was conducted in Kirkuk/Iraq, 200 patients with CRC and 200 cancer free control subjects were enrolled. Genomic DNA was extracted from venous blood samples and screened for SNPs using Restriction Fragment Length Polymorphism (RFLP) and confirmed by the direct DNA sequencing. Results: The reference genotype of CYP1A1 gene rs1048943 is AA. Both the AG and GG variants were significantly more frequent in the cancer group and associated with increased risks of CRC and its later stages (stages III and IV) and poor differentiation (p0.05) or with tumour stage or its grade (p>0.05). The GG genotype of CYP1B1 rs1056836 was the reference genotype. The CG and CC variants were not associated with increased risks of CRC (P>0.05) or its stage or grade except the CG genotype which was associated with poor differentiation (OR= 3.4, 95 % CI= 1.8 -6.5, P

Milk fever (Hypocalcemia) is a metabolic disorder that has serious economic impacts on health of dairy cattle and production. Current research endeavored to evaluate the clinical, hematological and some biochemical alterations in cows affected with milk fever in the Gogjalee region, Mosul in Iraq. This research was conducted on 30 local breed cows aged (three to seven years) from private farms diagnosed with postparturient paresis according to clinical signs and laboratory confirmations. Ten healthy cows served as control groups.Blood samples were taken from each animal for biochemical and hemogram analysis. Results showed typical clinical signsof milk fever with different stages of the disease. Significant (P

Aims/Introduction Abnormalities in Ca2+ signaling have a key role in hemodynamic dysfunction in diabetic heart. The purpose of this study was to explore the effects of streptozotocin (STZ)‐induced diabetes on Ca2+ signaling in epicardial (EPI) and endocardial (ENDO) cells of the left ventricle after 5–6 months of STZ injection. Materials and Methods Whole‐cell patch clamp was used to measure the L‐type Ca2+ channel (LTCC) and Na+/Ca2+ exchanger currents. Fluorescence photometry techniques were used to measure intracellular free Ca2+ concentration. Results Although the LTCC current was not significantly altered, the amplitude of Ca2+ transients increased significantly in EPI‐STZ and ENDO‐STZ compared with controls. Time to peak LTCC current, time to peak Ca2+ transient, time to half decay of LTCC current and time to half decay of Ca2+ transients were not significantly changed in EPI‐STZ and ENDO‐STZ myocytes compared with controls. The Na+/Ca2+ exchanger current was significantly smaller in EPI‐STZ and in ENDO‐STZ compared with controls. Conclusions STZ‐induced diabetes resulted in an increase in amplitude of Ca2+ transients in EPI and ENDO myocytes that was independent of the LTCC current. Such an effect can be attributed, at least in part, to the dysfunction of the Na+/Ca2+ exchanger. Additional studies are warranted to improve our understanding of the regional impact of diabetes on Ca2+ signaling, which will facilitate the discovery of new targeted treatments for diabetic cardiomyopathy., This is the first report to investigate the effects of streptozotocin‐induced diabetes on L‐type Ca2+ current simultaneously measured with Ca2+ transients in epicardial and endocardial left ventricular myocytes isolated from rats 5–6 months after the induction of diabetes. Streptozotocin‐induced diabetes causes a progressive increase in the amplitude of endocardial and epicardial myocyte Ca2+ transients that is independent of the L‐type Ca2+ current. The effect of streptozotocin‐induced diabetes on Ca2+ handling might be attributed, at least in part, to the dysfunction of the Na+/Ca2+ exchanger.

Objectives : To explore the changing patterns of long-stay patients (LSP) to improve the utilization of pediatric intensive care units (PICUs) resources. Methods : This is a 2-points cross-sectional study (5 years apart; 2014-2019) conducted among PICUs and SCICUs in Riyadh, Saudi Arabia. Children who have stayed in PICU for more than 21 days were included. Results : Out of the 11 units approached, 10 (90%) agreed to participate. The prevalence of LSP in all these hospitals decreased from 32% (48/150) in 2014 to 23.4% (35/149) in 2019. The length of stay ranged from 22 days to 13.5 years. The majority of LSP had a neuromuscular or cardiac disease and were admitted with respiratory compromise. Ventilator-associated pneumonia was the most prevalent complication (37.5%). The most commonly used resources were mechanical ventilation (93.8%), antibiotics (60.4%), and blood-products transfusions (35.4%). The most common reason for the extended stay was medical reasons (51.1%), followed by a lack of family resources (26.5%) or lack of referral to long-term care facilities (22.4%). Conclusion : A long-stay is associated with significant critical care bed occupancy, complications, and utilization of resources that could be otherwise utilized as surge capacity for critical care services. Decreasing occupancy in this multicenter study deserves further engagement of the healthcare leaders and families to maximize the utilization of resources.

Global HIV program stakeholders, including the US President's Emergency Plan for AIDS Relief (PEPFAR), are undertaking efforts to ensure that eligible people living with HIV (PLHIV) receiving antiretroviral treatment (ART) receive a course of TB preventive treatment (TPT). In PEPFAR programming, this effort may require providing TPT not only to newly diagnosed PLHIV as part of HIV care initiation, but also to treatment-experienced PLHIV stable on ART who may not have been previously offered TPT. TPT scale-up is occurring at the same time as a trend to provide more person-centered HIV care through differentiated service delivery (DSD). In DSD, PLHIV stable on ART may receive less frequent clinical follow-up or receive care outside the traditional clinic-based model. The misalignment between traditional delivery of TPT and care delivery in innovative DSD may require adaptations to TPT delivery practices for PLHIV. Adaptations include components of planning and operationalization of TPT in DSD, such as determination of TPT eligibility and TPT initiation, and clinical management of PLHIV while on TPT. A key adaptation is alignment of timing and location for TPT and ART prescribing, monitoring, and dispensing. Conceptual examples of TPT delivery in DSD may help program managers operationalize TPT in HIV care.Les parties prenantes du programme mondial VIH, notamment le plan américain PEPFAR (US President’s Emergency Plan for AIDS Relief), entreprennent des efforts afin de s’assurer que les personnes vivant avec le VIH (PLVIH), éligibles, recevant un traitement antirétroviral (TAR), reçoivent également un traitement préventif TB (TPT). Dans la programmation PEPFAR, cet effort pourrait nécessiter de fournir le TPT non seulement aux PLVIH nouvellement diagnostiquées dans le cadre de l’initiation de la prise en charge du VIH, mais également aux PLVIH stables déjà traités par TAR à qui on n’aurait pas encore offert le TPT. L’expansion du TPT survient au même moment comme une tendance à offrir une prise en charge du VIH davantage centrée sur la personne à travers une prestation de services différenciée (DSD). Dans la DSD, les PLVIH stables sous TAR bénéficient d’un suivi clinique moins fréquent ou sont soignés hors du modèle traditionnel en structures de santé. Le décalage entre la prestation traditionnelle du TPT et la prestation de soins dans des DSD innovantes peut nécessiter des adaptations aux pratiques de prestation du TPT pour les PLVIH. Ces adaptations incluent des éléments de planification et d’opérationnalisation du TPT dans la DSD, comme la détermination de l’éligibilité au TPT et sa mise en route et la prise en charge clinique des PLVIH sous TPT. Une adaptation majeure est l’alignement en termes de temps et de lieu pour la prescription, le suivi et la délivrance du TPT et du TAR. Des exemples conceptuels de délivrance du TPT dans la DSD aideraient les gestionnaires de programme à rendre opérationnel le TPT au sein de la prise en charge du VIH.Los interesados directos del Programa Mundial del VIH, incluido el Plan de Emergencia del Presidente (de los Estados Unidos) para el Alivio del Sida (PEPFAR), emprenden ahora esfuerzos encaminados a garantizar que las personas con infección por el VIH (PLVIH), que siguen un tratamiento antirretrovírico (TAR) y que reúnen las condiciones, reciban un ciclo de tratamiento preventivo de la TB (TPT). En la programación del PEPFAR esta iniciativa puede necesitar la provisión de TPT no solo a las personas con un diagnóstico reciente de infección por el VIH, como parte del inicio de la atención del VIH, sino también a las PLVIH, con experiencia de tratamiento y que se encuentran estables recibiendo el TAR, a quienes tal vez no se haya propuesto antes el TPT. La ampliación del TPT ocurre de manera simultánea con la tendencia a ofrecer una atención del VIH más centrada en la persona mediante la prestación diferenciada de servicios (DSD). En la DSD, las PLVIH, estables con el TAR, pueden tener encuentros de seguimiento clínico menos frecuentes o recibir atención por fuera del modelo tradicional en los consultorios. La discordancia entre la provisión tradicional del TPT y la prestación de atención en el marco innovador de la DSD exige adaptaciones de las prácticas de prestación del TPT a las PLVIH. Las adaptaciones incluyen componentes de planeación y puesta en práctica del TPT en la DSD, como la determinación de los criterios para recibir el TPT, el inicio del mismo y el manejo clínico de las PLVIH mientras reciben el TPT. Una adaptación primordial es la coordinación del ritmo y el lugar de prescripción, supervisión y suministro del TPT y el TAR. La presentación de ejemplos teóricos de provisión del TPT en el marco de la DSD puede ayudar a los gerentes de programas a poner en práctica el TPT en la atención del VIH.

Introduction To identify the clinical characteristics and outcomes of hospitalized patients with COVID-19 in Oman. Methods A case series of hospitalized COVID-19 laboratory-confirmed patients between February 24th through April 24th, 2020, from two hospitals in Oman. Analyses were performed using univariate statistics. Results The cohort included 63 patients with an overall mean age of 48 ± 16 years and 84% (n = 53) were males. A total of 38% (n = 24) of the hospitalized patients were admitted to intensive care unit (ICU). Fifty one percent (n = 32) of patients had at least one co-morbidity with diabetes mellitus (DM) (32%; n = 20) and hypertension (32%; n = 20) as the most common co-morbidities followed by chronic heart and renal diseases (12.8%; n = 8). The most common presenting symptoms at onset of illness were fever (84%; n = 53), cough (75%; n = 47) and shortness of breaths (59%; n = 37). All except two patients (97%; n = 61) were treated with either chloroquine or hydroxychloroquine, while the three most prescribed antibiotics were ceftriaxone (79%; n = 50), azithromycin (71%; n = 45), and the piperacillin/tazobactam combination (49%; n = 31). A total of 59% (n = 37), 49% (n = 31) and 24% (n = 15) of the patients were on lopinavir/ritonavir, interferons, or steroids, respectively. Mortality was documented in (8%; n = 5) of the patients while 68% (n = 43) of the study cohort recovered. Mortality was associated with those that were admitted to ICU (19% vs 0; p = 0.009), mechanically ventilated (31% vs 0; p = 0.001), had DM (20% vs 2.3%; p = 0.032), older (62 vs 47 years; p = 0.045), had high total bilirubin (43% vs 2.3%; p = 0.007) and those with high C-reactive protein (186 vs 90 mg/dL; p = 0.009) and low corrected calcium (15% vs 0%; p = 0.047). Conclusions ICU admission, those on mechanical ventilation, the elderly, those with high total bilirubin and low corrected calcium were associated with high mortality in hospitalized COVID-19 patients.

BACKGROUND: Diagnosis of small choroidal melanoma is mainly based on tumour thickness, subretinal fluid, or lipofuscin pigment. Ultra-wide-field imaging (UWF) allows depiction of choroidal lesions through a red (RC) and a green channel (GC). Aim of the study was to determine the utility of this tool in the detection of small choroidal melanoma. METHODS: Retrospective cross-sectional study of patients with small choroidal pigmented lesions up to 3 mm in thickness. All patients underwent clinical and imaging assessment including UWF. Lesions were subcategorized based on thickness and lesion type. A qualitative assessment ensued using the red and green channels feature. RESULTS: A total of 152 patients were included. Melanotic naevi (76/152,50%) and small choroidal melanomas (55/152,36%) were the predominant types. Thickness was

Virtual clinics have been proposed as a method of reducing costs and improving services in the National Health Service (NHS). The aim of this research was to assess the attitudes of clinicians and patients towards virtual consultations in a department of oral and maxillofacial surgery (OMFS). Patients and clinicians at conventional OMFS adult outpatient clinics were prospectively interviewed using a structured questionnaire. Variables recorded included type of consultation, overall attitude, time travelled, and mode of transport. Patients' notes were assessed retrospectively to check if examinations had been done. A total of 146 patients (100%) completed the surveys, and 108 of them (74%) were amenable to having virtual consultations in the future. Such appointments may have been suitable for 19 patients who did not have examinations. Chi squared analysis showed no relation between type of appointment and preference for a virtual consultation (p=0.087). To introduce a virtual consultation system in our department and to assess its efficacy once implemented, further development and research are required.

Poliomyelitis, also known as polio, is a highly infectious viral disease, predominantly affecting children under five years old. The virus is transmitted from person-to-person and mainly spreads through the fecal-oral route. The virus multiplies in the intestine, from where it can invade the nervous system via the bloodstream, potentially causing paralysis. Polio symptoms include fever, fatigue, headache, vomiting, neck stiffness and pain in the limbs. The disease causes permanent paralysis in one out of 200 infections. Currently, there is no cure for polio; it can only be prevented by immunisation.1.

Influenza causes significant morbidity and mortality worldwide. Owing to its ability to rapidly evolve and spread, the influenza virus is of global public health importance. Information on the burden, seasonality and risk factors of influenza in countries of the World Health Organization Eastern Mediterranean Region is emerging because of collaborative efforts between countries, WHO and its partners over the past 10 years. The fourth meeting of the Eastern Mediterranean Acute Respiratory Infection Surveillance network was held in Amman, Jordan on 11–14 December 2017. The meeting reviewed the progress and achievements reported by the countries in the areas of surveillance of and response to seasonal, zoonotic and pandemic influenza. The first scientific conference on acute respiratory infection in the Eastern Mediterranean Region was held at the same time and 38 abstracts from young researchers across the Region were presented on epidemiological and virological surveillance, outbreak detection and response, influenza at the animal-human interface, use and efficacy of new vaccines to control respiratory diseases and pandemic influenza threats. The meeting identified a number of challenges and ways to improve the quality of the surveillance system for influenza, sustain the system so as to address pandemic threats and use the data generated from the surveillance system to inform decision-making, policies and practices to reduce the burden of influenza-associated illnesses in the Region. Keywords: EMARIS, Influenza, Eastern Mediterranean Region, WHO

Aim: To compare the effects of 5- and 50-nm naked and PEG-coated gold nanoparticles (AuNP) on proinflammatory cytokines (IL-1β, IL-6, TNF-α) expression and histopathological changes in liver and kidneys of rats. Materials & methods: Rats were injected with different nanoparticles and sacrificed after 24 h. Results: Both 5- and 50-nm AuNPs, and 50-nm PEG-AuNPs caused granular clumping of cytoplasm, edema and hydropic dystrophy in hepatic cells. Naked AuNPs of both sizes caused mild shrinkage, whereas 50-nm PEG-AuNPs enlarged the Bowman's space and capsule. Larger nanoparticles produced more profound mRNA expression of cytokines in both the organs. Conclusion: These findings suggest the roles of particle size and coating on immunological response and histopathological changes.

Background: Congenital cardiac defects have a wide spectrum of severity in infants. About 30-40% of patients with congenital cardiac defects will be symptomatic in the 1st year of life, while the diagnosis was established in 60% of patients by the 1st month of age. Objectives: To identify the occurrence of specific types of CHD among hospitalized patients and to evaluate of growth of patients by different congenital heart lesions. Methods: A retrospective study, done on ninety-six patients (51 male and 45 female) with congenital heart disease (CHD) admitted to central teaching hospital of pediatrics, Baghdad from 1st September 2009 to 30th of August 2010. Results: The most common congenital heart diseases (CHD) were ventricular septal defect (VSD), tetralogy of Fallot (TOF), patent ductus arteriosus (PDA), transposition of great arteries (TGA), pulmonary Stenosis( PS), and Atrial septal defect (ASD).The most common modes of presentation were respiratory infection and heart failure in acyanotic patients and cyanosis in cyanotic groups. The study showed that only patent ductus arteriosus and atrial septal defects were more common in female while all other lesions were equal male to female ratio or slightly more common in male. The effect of acyanotic congenital heart disease on growth (Wt) is more common than cyanotic congenital heart disease. Conclusions: VSD is the most common type of congenital heart disease and the most common cause of morbidity, while ASD is the least common cause of morbidity in patients with congenital heart disease. The most common modes of presentation of patients with CHD are respiratory infection and heart failure in acyanotic CHD while cyanosis is the most common presentation in cyanotic group.

Diabetes is a life-threatening syndrome occurring around the world; it can have huge complications and is documented by large amounts of medical data. Therefore, attempts at early detection of this disease took a large area of research and many methods were used to deal with diabetes. In this paper, different types of KNN algorithm have been used to classify diabetes disease using Matlab. The dataset was generated by the criteria of the American diabetes association. For the training stage, 4900 samples have been used by the classifier learner tool to observe the results. Then, 100 of the data samples were used for the test. The results show that the KNN types (Fine, Weighted, Medium and Cubic) give high accuracy over the Coarse and the Cosine methods. Fine KNN is considered the most suitable according to its accuracy of classified samples.

Highlights • GIST is rare and its presentation as spontaneous rupture is extremely rare. • GIST preoperative diagnosis remains difficult. • Local excision of the GIST associated with the use of imatinib is effective. • GIST is a rare pathological condition., Introduction The incidence of small bowel tumors is comparatively rare when compared to colonic tumors. They comprise less than 10% of all gastrointestinal neoplasms. Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract; however it accounts for less than 1% of all gastrointestinal tumors. Aim To report a rare case of jejunal gastrointestinal stromal tumor presenting as a life-threatening emergency in a young adult male who was treated in the General Surgery department in the Jordanian Royal Medical Services (JRMS), Amman, Jordan. PRESENTED CASE: We report a 59-year-old male who presented to our emergency department with severe generalized abdominal pain. The patient was in a hypovolemic shock. Abdominal examination revealed a massively distended, tender abdomen. Abdomenal CT scan with IV contrast showed significant fat stranding around the jejunum associated with pneumoperitoneum and free fluid. Exploratory laparotomy was emergently performed, revealing diffuse peritonitis secondary to perforated small bowel tumor. En bloc resection was performed. Histopathologic examination confirmed the presence of malignant gastrointestinal stromal tumor of the jejunum with R0 clearance. Discussion Gastrointestinal stromal tumors are relatively rare and the jejunum is the least affected among other parts of the GI tract. The majority of ruptured GISTs occur spontaneously, and are located in the stomach and small bowel. Most ruptured GISTs are associated with dismal prognosis. Conclusion A jejunal gastrointestinal stromal tumor can rarely present with spontaneous perforation. However, it is important to highlight this condition, as early emergency intervention constitutes the key to a good outcome.

Orbital recurrence of malignant choroidal melanoma is quite uncommon, occurring in about 3% of patients undergoing enucleation for large tumors. Orbital recurrences after more than 10 years from enucleation are even rarer. In literature, only few reports described orbital recurrence that occurred between 10 and 40 years after primary diagnosis. Herein we report a very late choroidal melanoma recurrence, 40 years post enucleation, of a 52 year-old female who had undergone left enucleation at the age of 12. She presented to our clinic for consultation in 2017, complaining of difficulty to contain the prosthesis, as well as, presence of small pigmented palpable nodules inferiorly in her anophthalmic socket. The patient was not aware of the medical condition which had lead to the enucleation. We requested her medical reports and detailed history through her family. We realized after reviewing her charts 40 years back, that her enucleation was due to malignant choroidal melanoma (CMM). Full screening was performed. After magnetic resonance imaging (MRI), that showed the presence of nodular masses in the anophthalmic socket, an excisional biopsy was performed. Histopathology confirmed the diagnosis of CMM (epithelioid and spindle cell type), supporting the hypothesis that residual melanoma cells may remain clinically dormant for long periods, even for decades. A literature review was performed in order to review similar cases and to understand and discuss multiple factors, which may explain this extremely delayed recurrence. To the best of our knowledge, this is the third case to be reported in the literature.

To the best of our knowledge, there have been few reports in the literature about perineal injury without an associated pelvic fracture. In this report, we are going to discuss the mechanism, management, and outcome of two cases of perineal injury associated with car accidents. The two cases, one male and one female, presented with sustained isolated soft tissue injuries to the perineum. Both cases revealed a separated anorectum from the coccyx and sacrum without detectable damage to the lumen or surrounding sphincter. Pelvis fracture was not present in either case nor did the urinary bladder or urethra show signs of injury. A defunctioning (temporary) colostomy medical innervation was done to both and the perineal wound was left to heal. At last, both patients were satisfied with the final outcome.

P86 Table 1Anosmia scoring system developedScore for each smell Meaning 0 Able to identify the smell correctly 1 Able to identify the smell but it doesn’t smell right 2 Unable to identify the smell 3 Total anosmia Total scores per patient Definition 0–4 Mild anosmia 5–10 Moderate anosmia 11–15 Severe anosmia ConclusionA significant proportion of patients studied were not aware they had anosmia. This has implications for pandemic management going forward when people are required to self-report this symptom and suggests potential benefit in formal examination of the olfactory nerve.

Background: Some, but not all, large-scale randomized controlled trials (RCTs) investigating the effects of marine ɷ-3 fatty acids supplementation on cardiovascular outcomes have reported increased risks of atrial fibrillation (AF). The potential reasons for disparate findings may be dose-related. Methods: The MEDLINE and Embase databases were searched for articles and abstracts published between January 1, 2012, and December 31, 2020, in addition to a meta-analysis of large cardiovascular RCTs published in 2019. RCTs of cardiovascular outcomes of marine ɷ-3 fatty acids that reported results for AF, either as a prespecified outcome, an adverse event, or a cause for hospitalization, with a minimum sample size of 500 patients and a median follow-up of at least 1 year were included. RCTs specifically examining shorter-term effects of ɷ-3 fatty acids on recurrent AF in patients with established AF or postoperative AF were not included. The hazard ratio (HR) for the reported AF outcomes within each trial was meta-analyzed using random effects model with Knapp-Hartung adjustment and evaluated a dose-response relationship with a meta-regression model. Results: Of 4049 screened records, 7 studies were included in the meta-analysis. Of those, 5 were already detected in a previous meta-analysis of cardiovascular RCTs. Among the 81 210 patients from 7 trials, 58 939 (72.6%) were enrolled in trials testing ≤1 g/d and 22 271 (27.4%) in trials testing >1 g/d of ɷ-3 fatty acids. The mean age was 65 years, and 31 842 (39%) were female. The weighted average follow-up was 4.9 years. In meta-analysis, the use of marine ɷ-3 fatty acid supplements was associated with an increased risk of AF (n=2905; HR, 1.25 [95% CI, 1.07–1.46]; P =0.013). In analyses stratified by dose, the HR was greater in the trials testing >1 g/d (HR, 1.49 [95% CI, 1.04–2.15]; P =0.042) compared with those testing ≤1 g/d (HR, 1.12 [95% CI, 1.03–1.22]; P =0.024; P for interaction P =0.001). Conclusions: In RCTs examining cardiovascular outcomes, marine ɷ-3 supplementation was associated with an increased risk of AF. The risk appeared to be greater in trials testing >1 g/d.

Purpose of study Veno-Arterial Extra-corporeal Membrane Oxygenation (VA-ECMO) is indicated for refractory cardiac and/or respiratory failure. Adverse events remain considerable despite best practices. We specifically aimed to understand risk factors associated with cerebrovascular accidents (CVA) in patients who underwent VA-ECMO support. Methods We retrospectively assessed all VA-ECMO patients from 2007 to 2019 at our institution. We identified those who experienced a CVA while supported by VA-ECMO. Patients with the primary event (CVA) were matched to controls (no CVA) based on age and sex. Comparisons were made between groups using McNemar's, Mantel-Haenszel, and Wilcoxon Signed-Rank tests where appropriate. Results Of the 278 VA-ECMO patients in the registry, 32 patients who experienced a CVA were identified; 24 (8.6%) ischemic and 8 (2.9%) hemorrhagic. Median age was 59.5 years (inter-quartile range: 49–65 years) and 75% of patients were males. Hypertension, diabetes, CAD and CHF were common co-morbidities (Table 1). Cardiogenic shock was the most common indication for VA-ECMO support in both cohorts, 75% in cases and 71.9% in controls. Cannulation strategies were identified as central or peripheral. There was a significant association of duration of VA-ECMO support with incidence of CVA, with a p-value of 0.03. Regression analysis showed a trend of increased risk of CVA by 4% for each additional day on VA-ECMO, however, this was not statistically significant (Odds ratio: 1.04; confidence interval 1.00–1.08). Most common outcome was death followed by decannulation to recovery and bridge to LVAD. Conclusion Ischemic and hemorrhagic CVAs are not uncommon during VA-ECMO support. Our case control study shows an association of duration of VA-ECMO support with incidence of CVA. This underscores the importance of timely assessment and weaning or bridging of VA-ECMO patients to their next management step. Funding Acknowledgement Type of funding sources: None.

Background Our study sought to determine the frequency of Needlestick injuries (NSIs) among Healthcare Workers (HCWs) working at governmental hospital and to study the factors that associated with occurrence of NSIs, and to develop recommendations for a comprehensive program for prevention. Methods Retrospective study of all reported cases of NSIs in the period from April 2016 to May 2018 among healthcare workers at a governmental hospital. Results Incidence of NSIs over 26 months was 8.4% among all participants. Nurses were the most affected staff (52.5%) resulted commonly from disposing syringes (58.9%). In contrast, the incidence of NSIs among physicians was 24.9% where surgical devices were the primary source of NSIs among them (40%). Failure to complete all required hepatitis B vaccination was common among expatriates of the participants of this study. Conclusions NSIs was common among HCWs participated in this study. Preventive measures should be implemented including adequate hepatitis B immunization.

AimsThe emergence of the COVID-19 global pandemic, with a high transmission and mortality rate, has created an extraordinary crisis worldwide. Such an unusual situation may have an undesirable impact on the mental health of individuals which, in turn, may influence their outcomes. This study aimed to explore the influence of the COVID-19 pandemic on the psychological disposition of residents of the Kingdom of Saudi Arabia.MethodsA cross-sectional study using an online survey was conducted in Saudi Arabia between 27 March and 27 April 2020. The Patient Health Questionnaire (PHQ-9) and Generalised Anxiety Disorder-7 (GAD-7) were used to assess depression and anxiety. Logistic regression analysis was used to identify predictors of these.ResultsA total of 2,081 individuals participated in the study. The prevalence of depression and anxiety among the study participants was 9.4% and 7.3%, respectively. Non-Saudi residents, individuals aged 50 years and above, divorced people, retired people, university students, and those with an income between 2,000 and 10,000 SR were at higher risk of developing depression. Saudi individuals, married people, the unemployed, and those with a high income (> 10,000 RS) were at higher risk of developing anxiety.ConclusionWe found that there is a wide range of Saudi residents who are at higher risk of developing mental illness during the current COVID-19 pandemic. Policymakers and mental healthcare providers are advised to provide continuous monitoring of the psychological consequences during this pandemic and provide the required health support.What is already known about this subject?–The emergence of the COVID-19 global pandemic, with a high transmission and mortality rate, has created an extraordinary crisis worldwide.–The COVID-19 pandemic might have an undesirable impact on the mental health of individuals.What does this article add?–Depression and anxiety are common among the Saudi population.–A considerable proportion of the Saudi population is concerned about contracting COVID-19 or transmitting it to family members.–Unemployed individuals and university students are at higher risk of depression and anxiety.

A colon lipoma is defined as a benign tumor made of adipose tissue present in the submucosa. Lipomas of the colon are unusual with a frequency of 0.035%-4.4%. We present an uncommon case of a 41-year-old female with left colonic lipoma causing intussusception. The patient presented with abdominal pain at the left iliac fossa. She underwent an emergency exploratory laparotomy plus left hemicolectomy and was followed in the surgical out-patient clinic postoperatively. She was found doing well taking a normal diet and having normal bowel habits. The overall prognosis depends on the complete removal of the tumor.

Objectives: We aimed to determine epidemiological risk factors associated with acquiring severe coronavirus disease 2019 (COVID-19) in patients requiring hospitalization. Methods: A prospective cohort study was conducted using a questionnaire comprised of six closed-ended questions to identify potential risk factors for severe COVID-19. Using COVID-19 associated illnesses and complications (pneumonia, acute respiratory distress syndrome, need for mechanical ventilation, acute kidney failure, cardiac failure, and thromboembolic events), we derived an index variable to measure the severity of COVID-19 in patients. Results: We included 143 adult patients with confirmed COVID-19 of whom 62.2% (n = 89) were male and 37.8% (n = 54) were female. The average age of the cohort was 50.6±16.5 years. Our study found that being a female, working at the health care facility, being a healthcare worker, attending a mass gathering within the last 14 days, attending a gathering with 10 persons or less, and being admitted to a hospital were associated with increased risk of developing severe COVID-19. The only risk factor associated with severe COVID-19 was working at a health care facility (odds ratio = 33.42, p =0.029). Conclusions: Intervention directed to control risk factors associated with acquiring severe COVID-19 should be a core priority for all countries, especially among high-risk occupations and workplaces, including working at a health care facility. A risk-based approach to prioritize vaccination among these high-risk individuals should be supported to strengthen the implementation of non-pharmaceutical interventions.

OBJECTIVES: To assess health-related quality of life (HRQoL) and its predictors among individuals with chronic vision conditions during COVID-19 lockdown. METHODS: A cross-sectional, survey-based study targeted Jordanian adults with a variety of chronic vision conditions requiring regular ophthalmic follow-up. Outcome measures included HRQoL measured by the 12-item Short-Form Health Survey (SF-12), mental health symptoms measured by the Depression Anxiety Stress Scale, and vision ability measured by the National Eye Institute Visual Functioning Questionnaire (VFQ-25) General Vision and Role Limitation subscales. Data were analyzed descriptively and using a multiple variable linear regression model to identify HRQoL predictors. RESULTS: A total of 203 participants with a mean age of 52.09 (±15.41) years participated, and SF-12 mean scores were 58.15 for the physical component and 57.48 for the mental component. The level of HRQoL was significantly associated with VFQ-25 Role Limitation subscale, diabetes, the need of ophthalmic follow-up, and stress. The regression model explained 47.1% of the variance in HRQoL (r2=0.471, F=35.57, P

Diabetic peripheral neuropathy (DPN) is the most common type of diabetic neuropathy. It accounts for significant morbidity, including lower extremity amputations. There are few studies on the prevalence of DPN among Palestinian refugees in Jordan. This study aimed to determine the prevalence of DPN and its associated factors among Palestinian refugees with diabetes in the Nuzha area of Jordan, using the Michigan Neuropathy Screening Instrument (MNSI).A cross-sectional study was conducted at the UNRWA Nuzha Health Centre, Amman, Jordan, during the first quarter of 2016 (Jan 2-Mar 31, 2016). The Nuzha Health Centre was randomly chosen from the UNRWA clinics in Jordan. Study participants were selected by systematic random sampling. The number of participants was decided with Cochran's formula and adjusting the sample size by use of the finite population correction equation. 343 patients with diabetes were assessed for DPN using the history and physical assessment sections of the MNSI. We generated descriptive statistics, and tested for associations between variables using univariate and multivariate logistic regression analysis to identify the best subset of predictors for the presence of DPN. We used SPSS version 22 to input and analyse data. This study was approved by the UNRWA Jordan Field Office and the Institutional Review Board at the University of Jordan, and by the Michigan Diabetes Research Centre, which gave its permission to use the MNSI. Written informed consent was obtained from each participant.Prevalence of DPN was 11% (37 of 343) based on the history section and 36% (122 of 343) based on the physical assessment section of the MNSI. Multivariate logistic regression revealed that significant predictors for DPN based on the history section of the MNSI were education level and duration of diabetes. Compared with participants with no education, the odds ratio (OR) for DPN was 0·13 (95% CI 0·04-0·49, p=0·0023) for participants with elementary education, 0·11 (0·03-0·49, p=0·0035) for those with high school education, and 0·04 (0·01-0·41, p=0·0070) for those with a diploma. Compared with participants who had diabetes for less than 10 years, the OR for DPN was 7·69 (1·99-30·30, p=0·0031) for those who had diabetes for 10-19 years and 32·26 (6·76-142·86, p0·0001) for those who had diabetes for 20 years or longer. However, the predictors for DPN based on the physical assessment part of MNSI were age, duration of diabetes, and type of treatment for diabetes. Compared with participants aged 70 years or older, the OR for DPN was 0·18 (0·04-0·89, p=0·036) for those aged 40-49 years and 0·22 (0·06-0·82, p=0·024) for those aged 50-59 years. Compared with participants who had diabetes for less than 10 years, the OR for DPN was 32·26 (13·70-76·92, p0·0001) for those who had diabetes for 10-19 years and 200 (34·48-1000, p0·0001) for those who had diabetes for 20 years or longer. The OR for DPN was 0·23 (0·08-0·70, p=0·0094) for participants who were treated with oral hypoglycemic agents alone, compared those who were treated with insulin and oral hypoglycaemic agents.The prevalence of DPN is high among Palestinian refugees with diabetes in the Nuzha area, Jordan, consistent with the results of other studies of DPN in individuals with diabetes. There is a need for early detection and regular screening for DPN in patients with diabetes, with special attention given to patients with risk factors for DPN.None.

Purpose To compare the treatment efficacy of optical correction and occlusion therapy and/or penalization for different anisometropic refractive errors (hyperopic, myopic, and mixed). Methods Medical records of 51 patients with anisometropic amblyopia managed by both optical correction and occlusion therapy and/or penalization were evaluated retrospectively. Patients were categorized into hyperopic, myopic or mixed anisometropia groups. Cycloplegic refraction, spherical anisometropia, baseline visual acuity, baseline interocular difference, final visual acuity and final interocular difference were analyzed to assess association between type of anisometropia with both resolution of anisometropic amblyopia and the time required to achieve it. Results Baseline visual acuity of the amblyopic was 0.94±0.47 in the hyperopic group; 1.12±0.56, in the myopic group; and 1.08 ±0.39 in the mixed group. Final visual acuity in the amblyopic eye was 0.34±0.30 in the hyperopic group, 0.78±0.59 in the myopic group, and 0.78±0.56 in the mixed group. The difference in final visual acuity in the amblyopic eye between the groups was significant (P=0.014). The amblyopia was improved in 50% of patients in the hyperopic group, 23.8% in the myopic group, and 14.3% in the mixed group (P=0.081). The type of anisometropia was significantly associated with the improvement of visual acuity in the amblyopic eyes (P=0.044). The mean time for amblyopia improvement was 16.50±10.52 months in the hyperopic groups, 15.60±12.44 months in the myopic group, and 21.00±21.21 months in the mixed group (P=0.947). Conclusion Lower amounts of hyperopic anisometropia are as amblyogenic as higher amounts of myopic or mixed anisometropia. Mean improvement in visual acuity of an amblyopic eye with both optical correction, occlusion therapy and/or penalization is higher in patients with hyperopic anisometropia in comparison with myopic or mixed anisometropia. No significant difference was found in the time required to achieve improvement between the study groups.

The fluticasone propionate/formoterol fumarate (hereafter fluticasone/formoterol) 50/5 µg pressurized metered-dose inhaler (pMDI) [Flutiform®] is a fixed-dose combination of an inhaled corticosteroid (ICS) and a long-acting β2-adrenoceptor agonist (LABA) for the regular treatment of asthma where regular use of an ICS and a LABA combination product is appropriate. In the EU, the fluticasone/formoterol 50/5 µg pMDI is recommended for use in adults, adolescents and children aged ≥ 5 years, with the latter being a recent expansion of the indicated population and the focus of this review. Fluticasone/formoterol 50/5 µg, administered as two actuations (i.e. 100/10 µg) twice daily, provided benefit over fluticasone propionate 100 µg twice daily and was noninferior to fluticasone/salmeterol 100/50 µg twice daily, in improving lung function in patients aged 5 to

Background: For the N1b papillary thyroid carcinoma (PTC) patients, modified radical neck dissection (MRND) encompassing levels II – V is generally recommended. However, routine level V dissection is controversial because of the low incidence of metastasis/recurrence in level V and the increased morbidities associated with level V dissection. Objective: This study was designed to determine the clinical risks and benefits of routine level V dissection in N1b PTC patients with clinical negative level V. Patients and Methods: This study was a prospective, comparative, randomized and descriptive study of 40 patients suffering N1b papillary thyroid carcinoma. The patients were divided into two equal groups: Group 1 subjected to MRND, and Group 2 subjected to SND. Both groups were compared for age, sex, intraoperative (duration of surgery and complications) and postoperative results (complications and distribution of lateral nodal recurrence). Results: Under a matched condition, occult level V metastasis was observed in 5.0%. The MRND group exhibited a significantly longer operation time compared with the SND group. The amount of drainage was significantly more in the MRND group compared with the SND group. Time of drain removal was significantly less in the SND group compared to MRND group. Chyle leak was more frequent in the MRND group compared with the SND group but not statically significant. Level V recurrences did not occur in 3 recurred N1b PTC patients who underwent unilateral MRND and SND. Shoulder syndrome encompassing shoulder dysfunction and pain was significantly more frequent in the MRND group than in the SND group. There were no statistically difference between the groups according to infection, transient hypocalcaemia, transient RLN palsy and nodal recurrence. Conclusion: Because of the low incidence of metastasis/recurrence in level V and the clear evidence of increased morbidities, level V dissection in N1b PTC patients may be reserved for those clinically/radiologically evident metastasis in level V.

Apalutamide (marketed as Erleada®) is an oral non-steroidal next-generation selective inhibitor of the androgen receptor (AR), and is approved in several countries, including the USA and those of the EU, for the treatment of non-metastatic castration-resistant prostate cancer (nmCRPC). In men with nmCRPC who were receiving androgen-deprivation therapy (ADT) and had a high risk of metastases in SPARTAN, apalutamide significantly prolonged metastasis-free survival (MFS) compared with placebo, with consistent benefits demonstrated across subgroups. The addition of apalutamide to ongoing ADT significantly prolonged time to metastasis and progression-free survival (PFS) compared with placebo, and maintained health-related quality of life (HR-QOL). Apalutamide was generally well tolerated in SPARTAN, with fatigue being the most frequently reported adverse event. Given the available evidence, apalutamide with ongoing ADT represents an emerging treatment option for patients with nmCRPC who are at high risk of developing metastatic disease.

AIM: This study aimed to assess the effectiveness of a recognised antimicrobial resistance (AMR) online module on knowledge and perception among dental students, using a randomised controlled trial study design. METHODS: Dental students (n = 64, aged 21-25 years) in clinical years agreed to participate in this triple-blinded, parallel, randomised controlled trial. There were 34 students in the study group and 30 students in the control group. The study group participated in an online course covering information about AMR, while students in the control group received another online course about microorganisms in dentistry. Both groups were assessed three times using online questionnaires: before the intervention (T1), after the intervention (T2), and two months later (T3). Each one of T1, T2 and T3 had 22 questions. The questions were repeated each time in T1, T2, and T3 asking about AMR but with different question format, to avoid the possibility of students to memorise the answers. RESULTS: The mean (m) of correct answers for all students on T1 was 12.56, with standard deviation (SD) of 3.2. On T2, m = 14.03 and SD = 3.85, and on T3, m = 14.36 and SD = 3.71. Scores ranged from 0 to 22. The participants in the study and control groups showed significant score improvements from T1 to T2, immediately after the intervention, but there was no significant difference between T2 and T3. The study group students’ scores did not improve significantly from T1 to T3, in contrast to the control group students’ scores. More importantly, there was no significant difference in improvement from T1 to T2 when comparing the study and control groups. CONCLUSION: Online courses might not be reliable learning methods for ensuring the optimal levels of AMR knowledge that are needed by dental practitioners.
