Background: The coronavirus disease 2019 (COVID-19) pandemic has severe consequences in terms of mortality and morbidity. Knowledge of factors that impact COVID-19 may be useful in the search for treatments.
Objectives: To determine the effect of glucose-6-phosphate dehydrogenase (G6PD) deficiency on morbidly and mortality associated with COVID-19.
Methods: All patients admitted to Hadassah Hebrew University Medical Center between 01 March 2020 and 03 May 2021 with a diagnosis of COVID-19 were included. We retrospectively retrieved demographic, clinical, and laboratory data from the hospital’s electronic medical records. The main outcomes were mortality, intensive care unit (ICU) admission, and severity of COVID-19.
Results: The presence of G6PD deficiency emerged as an independent protective predictor for ICU admission (odds ratio [OR] 0.258, 95% confidence interval [95%CI] 0.077–0.619, P = 0.003) and the development of critical illness (OR 0.121, 95%CI 0.005–0.545, P = 0.006). Moreover, patients with G6PD deficiency had a trend toward lower mortality rates that did not reach statistical significance (OR 0.541, 95%CI 0.225–1.088, P = 0.10).
Conclusions: Patients with G6PD deficiency were less likely to have a severe disease, had lower rates of ICU admission, and trended toward lower mortality rates.

Background: Several approaches are used to access the hip joint; most common are the direct lateral and posterior. Little consensus exists on which to use when treating hip fractures.
Objectives: To compare short-term complications, postoperative ambulation, and patient-reported outcome measures (PROMS) of direct lateral vs. posterior approaches in hemiarthroplasty for acute hip fractures.
Methods: We conducted a retrospective clinical trial with 260 patients who underwent bipolar hemiarthroplasty in the direct lateral or posterior approach (166 and 94, respectively) between January 2017 and December 2018. The clinical data included short-term complications: prosthetic dislocation, periprosthetic fractures, and infection. Postoperative ambulation was collected 6 weeks postoperatively; PROMS were collected for 173 patients at 2 years follow-up.
Results: There were six dislocations overall, average time to dislocation was 22 days postoperative (range 4–34). Five dislocations were after the posterior approach (5.3%) and one after direct lateral (0.6%) (P = 0.01). At 6 weeks follow-up, inability to walk was found in 16.9% of the direct lateral group and 6.4% of the posterior approach group (P = 0.02). In the posterior approach group, 76% could walk more than 20 meters; only half of the direct lateral group could (P = 0.0002). At 2 years follow-up, PROMS did not show a statistically significant difference between the groups.
Conclusions: Posterior approach for hemiarthroplasty following femoral neck fractures allows superior ambulation to the direct lateral approach only for the short-term. However, no long-term clinical advantage was found. This short-term benefit does not justify the increased dislocation rate in the posterior approach.

Background: Acute appendicitis (AA) is a medical emergency. The standard of care for AA had been surgical appendectomy. Recently, non-operative management (NOM) has been considered, mainly for uncomplicated AA.
Objectives: To evaluate AA NOM trends over two decades.
Methods: We conducted a retrospective cohort study based on Israel’s National Hospital Discharges Database (NHDD). Inclusion criteria were AA admissions from 1 January 2000 to 31 December 2019, with either primary discharged diagnosis of AA, or principal procedure of appendectomy. Predefined groups were children (5 ≤ 18 years) and adults (≥ 18 years). We compared the last decade (2010–2019) with the previous one (2000–2009).
Results: The overall AA incidence rate over two decades was 126/100,000/year; higher in children 164/100,000/year than 113/100,000/year in adults. Surgery was the predominant AA treatment in 91.9%; 93.7% in children and 91.1% in adults. There was an increase in AA NOM rates when comparing the previous decade (5.6%) to the past decade (10.2%); 3.2% vs. 9.1% in children and 6.8% vs. 10.7% in adults, respectively. Annual trends revealed a mild increase in AA NOM rates. Delayed appendectomy (within 90 days of AA NOM) was 19.7% overall; 17.3% in adults and 26.3% in children.
Conclusions: There was an increase in AA NOM rates during the last decade in the overall population. Since 2015, there has been a noticeable increase in AA NOM rates, probably associated with World Society of Emergency Surgery Jerusalem guidelines. Surgery is still the predominant treatment for AA despite the increasing trend in NOM.

Background: Surgical resection is the only curative option for gastric carcinoma (GC). Minimally invasive techniques are gaining popularity.
Objectives: To present a single-surgeon's experience in transitioning from an open to a minimally invasive approach, focusing on surgical and oncological outcomes.
Methods: We conducted a retrospective analysis including distal gastrectomy patients 2012–2020 operated by a single surgeon. Two cohorts were compared: open (ODG) and laparoscopic distal gastrectomy (LDG).
Results: Overall, 173 patients were referred for gastrectomy during the study years. We excluded 80 patients because they presented with non-GC tumors, underwent proximal or total gastrectomy, or underwent palliative surgery. Neoadjuvant treatment was administered to 62 patients (33.3%). Billroth 1 was the preferred method of reconstruction (n=77, 82.8%), followed by Roux-en-Y (n=12, 13%). Fifty-one patients (54.8%) underwent LDG, 42 (45.2%) underwent ODG. The LDG group had significantly shorter lengths of stay (6 days, interquartile range [IQR] 1–3 5–8 vs. 5 days, IQR 1–3 4–6, P = 0.001, respectively), earlier return to oral feeding (1 day, IQR 1–3 1–3 vs. 2 days, IQR 1–3 1–3.2, P < 0.001), and earlier removal of drains (4 days, IQR 1–3 3–5.2 vs. 5 days, IQR 1–3 3.5–6.7, P < 0.001). Overall lymph node yield was 30 (IQR 1–3 24–39) and was similar among groups (P = 0.647).
Conclusions: Laparoscopic techniques for resection of distal GC are feasible and safe, leading to good perioperative outcomes and adequate lymph node yield.

Background: Type 2 diabetes mellitus (T2DM) is a known risk factor for cardiovascular disease and stroke. Metformin is an old, relatively safe, first line therapy for T2DM; however, it has been associated with stroke.
Objectives: To study the effects of metformin use and vitamin B12 deficiency on stroke rate among patients with T2DM.
Methods: We conducted a prospective study of patients admitted with ischemic stroke within 12 months (starting March 2020). We studied the clinical impact of metformin on vitamin B12 deficiency and stroke evolution. Student's t-test and ANOVA were used to compare the groups of patients and to determine whether there was any direct or indirect effect of metformin use on vitamin B12 deficiency and stroke.
Results: In total, 80 patients were admitted with ischemic stroke. Clinical status and biochemical data were collected and compared with healthy volunteers. There were 39 diabetic patients, 16 took metformin for at least 1 year. Among those who took metformin for at least 1 year, 9 had vitamin B12 level < 240 pg/ml (56.2%); 23 diabetic patients did not get metformin and only 4 had vitamin B12 level < 240 pg/ml (17.4%) (P = 0.014).
Conclusions: T2DM is a significant risk factor to the development of ischemic stroke. We found an association between metformin use and vitamin B12 deficiency and an association between vitamin B12 deficiency and stroke risk in patients with T2DM. Diabetic patients who are taking metformin should monitor their vitamin B12 level.

Background: Omega-3 fatty acids promote fertility in males and females and constitute an important factor in the normal development of the fetus.
Objectives: We investigated the effect of omega-3 supplements during ovulation induction treatment in women with polycystic ovary syndrome (PCOS)-related infertility.
Methods: A randomized, double-blind study was conducted for 60 treatment cycles in 34 women with PCOS-related oligo/anovulation referred to the fertility clinic at the Bikur Cholim/Shaare Zedek Medical Center in Jerusalem, who underwent ovulation induction with clomiphene citrate (50 mg). Seventeen women (mean age 33.9 ± 0.9 years) received omega-3 supplements (3 × 600 mg/day) and 17 received placebo capsules (mean age 32.7 ± 0.9 years) for a maximum of two cycles. We recorded their characteristics and data from their serial hormonal blood tests and ultrasound examinations. We also conducted both univariate and multivariate analyses. The primary endpoint was conception.
Results: There were clinical pregnancies in 8/30 (26.7%) treatment cycles for women receiving omega-3 supplements versus 4/30 (13.3%) cycles with placebo. Among overweight/obese women (body mass index [BMI] 25–35), there were clinical pregnancies in 8/27 cycles (29.6%) versus 1/19 (5.3%) with placebo (P < 0.04). For overweight/obese PCOS women, omega-3, lower BMI rates, and higher values of the endometrium’s thickness increased the odds of becoming pregnant. No harmful side effects from the omega-3 treatment were reported.
Conclusions: Omega-3 supplements demonstrated beneficial effects for fertility in women diagnosed with PCOS. Among the overweight/obese participants, the increased clinical pregnancy rate was significant.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1-RA) are new antidiabetic drugs that are recommended by current guidelines as a class I novel glucose-lowering treatment that improves cardiovascular outcome in type 2 diabetes mellitus (T2DM), particularly in patients with cardiovascular disease.
Objectives: To evaluate adherence to the current guidelines for treatment with SGLT2i and GLP1-RA drugs in patients referred to ambulatory consultant cardiology clinics with pre-existing T2DM.
Methods: We studied consecutive new patients with a pre-existing diagnosis of T2DM who were referred to the Clalit Health Services ambulatory consultant cardiology clinic over a 6-month period. The recorded information included demographics, co-morbidities, and prescribed drugs at patient admission.
Results: During the study period, 1782 patients visited our outpatient cardiology clinic. At screening, T2DM was present in 428 patients (24%); 77 (18%) were being treated with SGLT2i, and 39 (9.1%) with GLP1-RA. Patients receiving SGLT2i and GLP1-RA were younger and had more coronary artery disease, lower mean left ventricular ejection fraction, and higher mean estimated glomerular filtration rates than those who were not receiving these drugs. HbA1C was > 7 in 205 (47.9%) patients and > 7.5 in 136 patients (31.8%). Body mass index was > 30 kg/m2 in 231 (54%) patients.
Conclusions: GLP1-RA and SGLT2i drugs were found to be administered more frequently than previously reported, but they are not yet satisfactorily prescribed.

Background: Due to the high variability in malignancy rate among cytologically indeterminate thyroid nodules (Bethesda categories III–V), the American Thyroid Association recommends that each center define its own categorical cancer risk.
Objectives: To assess cancer risk in patients with cytologically indeterminate thyroid nodules who were operated at our center.
Methods: In a retrospective study, we analyzed the pathology results of all the patients whose fine needle aspiration results showed Bethesda III–V cytology and who subsequently underwent total thyroidectomy or lobectomy from December 2013 to September 2017.
Results: We analyzed 56 patients with indeterminate cytology on fine needle aspiration. Twenty-nine (52%) were defined as Bethesda III, 19 (34%) Bethesda IV, and 8 (14%) Bethesda V category. Malignancy rates were 38%, 58%, and 100% for Bethesda categories III, IV, and V, respectively. Most malignancies in Bethesda categories III and IV were follicular in origin (follicular thyroid carcinoma and follicular type papillary thyroid carcinoma), while 100% of the patients with Bethesda category V were diagnosed with classical papillary thyroid carcinoma. No correlation was found between sonographic and cytological criteria of nodules with Bethesda categories III and IV and rates of malignancy.
Conclusions: We found higher than expected rates of malignancy in indeterminate cytology. This finding reinforces the guidelines of the American Thyroid Association to establish local malignancy rates for thyroid nodules with indetermined cytology.

Leonardo da Vinci was a man of art and science. He became the archetype of the Renaissance era. Leonardo exhaustively studied the proportions of the body, drawing Vitruvian Man in 1490. It is regarded as a universal cultural icon. Leonardo's anatomical illustrations were of notable precision, and he is still considered as the pioneer of modern anatomy. We focus on Leonardo's masterpiece Virgin of the Rocks, which displays the intersection between his prodigious artistic talent and his commitment to science. This master painting discloses discordance between the artist's vast anatomical knowledge and its actualization in the painting. Consequently, many enigmas arise: How could the expert of anatomy, considered as the canon man of proportions, paint anatomical errors and why did he not actualize his knowledge in the painting? Was this an error or intentional? Could the painting techniques he used explain optical illusions that distorted the images? Was he so far ahead of his time that he did not feel compelled to paint realistically, but rather preferred to let his imagination and creativity run free? Some 500 years after Leonardo da Vinci's death, there is no one answer, but there is room for much speculation.
