Background: School closures due to the coronavirus disease 2019 (COVID-19) outbreak affected students physically, socially, and psychologically with an increase in the number of children and adolescent presenting with anxiety, depression, and drug abuse.
Objectives: To examine the impact of COVID-19 and lockdown on the mental health of minors during the pandemic period and to characterize the type and number of referrals to a regional psychiatric outpatient clinic.
Methods: This study included 380 children evaluated in an outpatient child psychiatric clinic. They were divided into two groups: before the lockdowns (BLD) (n=248), from January 2019 to February 2020, and during the lockdowns (LD) (n=132), from March 2020 to April 2021.
Results: When comparing the LD to BLD, there was increase in suicide attempts (9.8% vs. 2.8%) and in the use of psychotherapy (81% vs. 56%). There was a decrease in the diagnoses of behavior disorders (29.5% vs. 44.8%) and ADHD (29.5% vs. 50%); as well as a decrease in stimulant usage (22.7% vs. 38%). There was a statistically non-significant increase in the number of children with depression, anxiety, and drug-use disorder.
Conclusions: Many children developed educational, social, emotional, and behavioral gaps during LD, and they lost skills to deal with everyday problems due to social isolation. It is important to follow the long-term impact of the lockdowns and social isolation.

Background: Timely extubation is important integral part of the treatment of intensive care patients.
Objective: To evaluate hand grip strength using a Jamar Hydraulic Hand Dynamometer as a predictor of success or failure in weaning from ventilation.
Methods: This prospective study included 104 patients (62 males, 42 females) who were ventilated in the general intensive care unit (ICU), and who were alert and cooperating. They undertook a hand grip strength test using the Jamar dynamometer, within hours of extubation. Patients needing resuscitation within 72 hours were defined as failure.
Results: Success rate in weaning from ventilation was 85.6%, and 89 patients successfully weaned from ventilation. Those who were successfully weaned had stronger hand grip than those who failed. Males had a mean kg-strength 31.3 ± 11.5 vs. 23.6 ± 10.3 (P = 0.033), and in females mean kg-strength 23.14 ± 16.39 vs. 11.67 ± 10.33 (P = 0.031). A threshold value (22.5 kg-strength) was found to predict success for weaning from ventilation in the male group, with a sensitivity of 70.0% and a specificity of 62.5%. In the female group, the duration of the ventilation alone was statistically significant (P = 0.049).
Conclusions: There was a connection between hand strength and success in weaning from ventilation. A threshold value can help the medical staff to decide on extubation. Hand grip strength can predict successful weaning from ventilation and does not require high skills, time, a large staff, or high financial cost, and it does not endanger the patient.

Background: Congenital hypothyroidism (CH) is the most common preventable cause of mental retardation and delayed growth in children. Several prenatal and environmental factors might be associated with the disease.
Objectives: To determine the prevalence and risk factors of permanent CH and transient congenital hypothyroidism (TCH) in Israel.
Methods: We conducted a retrospective analysis of the Israeli national newborn screening program database from 2011 to 2015. Chi-square and logistic regression were used to assess the association of the demographic and gestational factors with the CH and TCH.
Results: Of the 889,033 live births screened between 2011 and 2015, 860 were diagnosed with CH (9.76 per 10,000 live births) and 298 with TCH (3.35 per 10,000 live births). In multivariate analyses, CH was positively associated with female sex, gestational ages < 38 or > 39 weeks, birth weight < 3000 grams, and winter birth. A decreased risk of TCH was detected in Arabs and neonates from high socioeconomic areas. An increased risk was independently associated with gestational ages < 38 weeks, low birth weight, and winter birth.
Conclusions: Several demographic, gestational, and geographical factors are associated with the development of CH and TCH. Future studies are needed to further investigate the pathogenesis in Israel.

Background: The adherence to a narrowband ultraviolet B (NB-UVB) treatment plan is derived, in large part, from the patient’s skin tolerance to the phototherapy dose. At present, the initial and first-month incremental phototherapy doses are determined prior to treatment initiation based on the patient's Fitzpatrick skin phototyping.
Objectives: To identify variables that predict adherence to NB-UVB first-month treatment dosage plan.
Methods: Charts of 1000 consecutive patients receiving NB-UVB at a hospital-based phototherapy unit were retrospectively analyzed. We included patients receiving NB-UVB for atopic dermatitis, psoriasis, vitiligo, and mycosis fungoides. The first-month NB-UVB treatment plan was determined based on the patient's Fitzpatrick phototype. Adherence to treatment was defined as receiving at least 80% of the planned first-month cumulative dose. We compared adherent vs. non-adherent patient groups for age, sex, Fitzpatrick phototype, presence of freckles, nevus count category, and type of dermatological disease.
Results: The study included 817 eligible patients, mean age 40 (2–95) years; 54% men; 32% had Fitzpatrick phototype I-II. Distribution by diagnosis was atopic dermatitis (29%), psoriasis (27%), vitiligo (23%), and mycosis fungoides (21%). Adherence to NB-UVB treatment plan was observed in 71% of patients. Adherence decreased with age, with 7% decrease per year (P = 0.03) and was higher among mycosis fungoides patients (77.3%) compared to all other diagnoses (69.8%; P = 0.02).
Conclusions: Adherence to NB-UVB treatment may be related to age and diagnosis. Fitzpatrick phototype-based first-month treatment plans should be modified accordingly.

Background: Blood pressure (BP) is routinely measured while triaging children presenting to the pediatric emergency department (PED).
Objectives: To determine whether a medical clown shortens the time to acquire a BP measurement among children undergoing triage in the PED.
Methods: The study comprised 133 children. Patients were assigned to one of two groups: with a medical clown or without a medical clown.
Results: The presence of a medical clown led to a significantly shorter time to acquire a blood pressure measurement (60 ± 23 seconds vs. 81 ± 43.5 seconds, P < 0.001. Clowns had a significant effect on shortening total triage length among children of Jewish ethnicity compared to Arab ethnicity (113 ± 353.6 seconds vs. 154 ± 418 seconds, P = 0.012).
Conclusions: Using medical clowns while measuring BP during triage when used in a culturally appropriate manner shortens time.

Background: Acute mesenteric ischemia (AMI) is a medical condition with high levels of morbidity and mortality. However, most patients suspected of AMI will eventually have a different diagnosis. Nevertheless, these patients have a high risk for co-morbidities.
Objectives: To analyze patients with suspected AMI with an alternative final diagnosis, and to evaluate a machine learning algorithm for prognosis prediction in this population.
Methods: In a retrospective search, we retrieved patient charts of those who underwent computed tomography angiography (CTA) for suspected AMI between January 2012 and December 2015. Non-AMI patients were defined as patients with negative CTA and a final clinical diagnosis other than AMI. Correlation of past medical history, laboratory values, and mortality rates were evaluated. We evaluated gradient boosting (XGBoost) model for mortality prediction.
Results: The non-AMI group comprised 325 patients. The two most common groups of diseases included gastrointestinal (33%) and biliary-pancreatic diseases (27%). Mortality rate was 24.6% for the entire cohort. Medical history of chronic kidney disease (CKD) had higher risk for mortality (odds ratio 2.2). Laboratory studies revealed that lactate dehydrogenase (LDH) had the highest diagnostic ability for predicting mortality in the entire cohort (AUC 0.70). The gradient boosting model showed an area under the curve of 0.82 for predicting mortality.
Conclusions: Patients with suspected AMI with an alternative final diagnosis showed a 25% mortality rate. A past medical history of CKD and elevated LDH were associated with increased mortality. Non-linear machine learning algorithms can augment single variable inputs for predicting mortality.

Background: Granulomatosis with polyangiitis (GPA) otologic manifestations include conductive and sensorineural hearing loss (HL). Vasculitis is assumed to be the primary cause of otologic manifestations. Deaf patients and patients with HL who do not benefit from hearing aids can benefit from cochlear implants (CI). There are currently no specific guidelines for treatment of patients with GPA suited for CI.
Objectives: To assess whether patients who are deaf due to GPA are good candidates for CI and if prior surgical or medical treatment of the inflammation are needed.
Methods: A case report is presented.
Results: A 71-year-old female patient with GPA and bilateral profound HL underwent CI. Prior to CI, preparation consisted of audiological evaluations by an otolaryngologist and a rheumatologist, followed by a course of prednisone and methotrexate for middle ear and nasal inflammations. CI was performed with no complications. The speech reception threshold and the monosyllabic word discrimination score after surgery were 25 dBHL and 75%, respectively.
Conclusions: Inflammation due to GPA can be controlled medically with immunosuppressive medications without subtotal petrosectomy, as in chronic suppurative otitis media. Satisfactory audiological results can be expected.

Background: Antibiotic resistance is a worldwide problem associated with increased morbidity and mortality.
Objectives: To evaluate multidrug resistant (MDR) bacteria carriage in selected populations.
Methods: Data were collected from all patients under 18 years who met our internal guidelines from 2015–2016. They were screened for carbapenem-resistant Enterobacteriaceae (CRE), extended spectrum beta-actamase (ESBL), methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococci (VRE). Indications for screening were non-resident non-Israeli patients (from the Palestinian Authority, Syria, and foreign patients), internal transfers from intensive care units, admission to high-risk departments, recent carriage of MDR bacteria, transfer from other hospitals, and recent hospitalization. Data were analyzed for MDR bacteria from at least one screening site (rectal, nasal, axillary, groin, throat). All data were analyzed per patient and per sample.
Results: During the study period 185/2632 positive screening sets (7%) were obtained from 725 patients. Of these, 165 patients (22.7%) were positive for at least one pathogen. Significantly fewer Israeli residents (120/615, 19.5%) tested positive compared to non-Israeli residents (45/110, 40.9%; P < 0.001). Past MDR bacteria carriage was the only significant screening indication (25/61, 41%; P < 0.001). CRE, VRE, MRSA, and ESBL prevalence rates were 0.6% (5/771), 0.5% (3/560) 0.5%, 4.2% (37/888), and 33.7% (139/413), respectively. Among non-ESBL carriers, MRSA was predominant with 38 positive cultures (n=34).
Conclusions: Non-Israeli non-residents and patients with previous positive MDR screening are at higher risk for MDR bacteria. Indications used to identify high-risk patients for drug resistant pathogens were efficacious. More effort is needed to reduce excessive sampling.

Background: Vaginal hysterectomy (VH) and colpocleisis are both used for the treatment of advanced pelvic organ prolapse (POP).
Objective: To compare short- and long-term outcomes of vaginal hysterectomy vs. colpocleisis for advanced POP.
Methods: Hospital and outpatient charts of patients who underwent VH or colpocleisis at our institution between January 2006 and December 2015 were reviewed. Clinical data were obtained and analyzed.
Results: In this study, 188 patients underwent VH and 32 patients underwent colpocleisis. The colpocleisis group was significantly older than the VH group (79.5 ± 4.5 vs. 69 ± 6.1 years respectively, P < 0.0001) and presented with significantly higher co-morbidity rates and a higher degree of POP. Perioperative blood loss was significantly lower (250 ± 7.6 ml vs. 300 ± 115 ml, P < 0.0001) and postoperative hospitalization was significantly shorter (2 ± 2.7 vs. 3 ± 2.2 days, P = 0.015) among the colpocleisis group. None of the patients from the colpocleisis group required an indwelling urethral catheter after discharge, compared to 27.5% of the patients from the VH group (P = 0.001). Total postoperative complication rate was significantly lower among the colpocleisis group (25% vs. 31% P < 0.0001). Objective recurrence of POP was significantly more common among the VH group (7% vs. 0% and 21% vs. 0% for the anterior and posterior compartments, respectively, P = 0.04).
Conclusions: Colpocleisis is associated with faster recovery, lower perioperative morbidity, and higher success rates than VH and should be considered for frail and elderly patients.

Background: Data regarding risk factors for superficial thrombophlebitis (STP) cases presenting to a hospital is limited.
Objectives: To investigate and stratify clinical and laboratory risk factors for STP
Methods: We conducted a retrospective case control study comparing patients presenting to the emergency department with STP and age- and gender-matched controls. We collected data on multiple risk factors and five blood indices.
Results: The study comprised 151 patients and matched controls. Patients with STP were more likely to have varicose veins (43.7% vs. 5.3%, P < 0.001), recent immobilization (14.6% vs. 1.3%, P < 0.001), obesity (36.4% vs. 18.5%, P = 0.001), a history of venous thromboembolism (VTE) or STP (27.2% vs. 0.7%, P < 0.001), and inherited thrombophilia (9.3% vs. 1.3%, P = 0.002). Following multivariate analysis, all five risk factors remained significant, with a history of VTE or STP associated with the largest risk (odds ratio [OR] 35.7), followed by immobilization (OR 22.3), varicose veins (OR 12.1), inherited thrombophilia (OR 6.1), and obesity (OR 2.7). Mean platelet volume was higher (8.5 vs 7.9 fl, P = 0.003) in STP cases.
Conclusions: A history of VTE or STP, immobilization, varicose veins, inherited thrombophilia, and obesity serve as independent clinical risk factors for STP presenting to hospital.

Background: The chloride intracellular channel (CLIC) protein family consists of six members in humans. CLICs are unique due to their metamorphic property, displaying both soluble and integral membrane forms. The transmembrane conformation was shown to give rise to ion-channel activity in vitro. In recent years, CLICs were implicated in a growing number of physiological processes in various organ systems and associated with distinct disease states. Indeed, the founding member of the family, CLIC5, was shown to be involved in hereditary deafness and various types of cancer. Nevertheless, the natural interactants and endogenous ligands of CLIC5 have not been discovered yet.
Objectives: To find ligands that affect the biochemical properties and activity of CLIC5. We hypothesized that such ligands could serve as important tools for resolving the long-sought cellular roles of CLICs and may offer novel therapeutic avenues for CLIC-associated conditions.
Methods: Using molecular biology and biochemical methods, CLIC5 was overexpressed in Escherichia coli and purified. Next, a high-throughput differential scanning fluorimetry thermal shift assay (TSA) was established and the interaction of approximately 500 natural compounds was examined.
Results: The TSA-based screening approach developed here allows to evaluate the effect of approximately 100 compounds in parallel within approximately 1 hour. Our proof-of-concept screening yielded 11 potential hits, significantly affecting the thermal stability of CLIC5. By examining the dose-dependence of this effect, we identified a specific interaction of CLIC5 with curcumin.
Conclusions: Using the approach we developed, large libraries of small molecules can be screened efficiently to identify novel CLIC5 interactants. Considering the participation of CLIC5 in various physiological and pathological processes, uncovering ligands that inhibit or activate CLIC5 may provide tools to modulate its activity and possibly to ameliorate CLIC5-related pathologies in the future.

Background: The exposure to ambient particulate matter (PM) is associated with increased morbidity and mortality from respiratory, cardiovascular, and other causes. A major contribution to this adverse effect is attributed to particles at the nanoscale range (ultrafine particles [UFP] particles < 100 nm). Most of the information about human exposure to PM has been collected by environmental monitoring of inhaled particles.
Objectives: To evaluate the use of direct measuring of UFP in the sputum as a biomarker for lung inflammation and functional impairment.
Methods: The study population included 121 patients who underwent an induced sputum (IS) test as a part of a clinical evaluation for respiratory symptoms. Cell differential count was performed, and the UFP content was measured in each IS sample. The UFP content in the sputum was compared among patients with different inflammatory phenotypes based on IS granulocytes levels: eosinophilic inflammation (EI) IS eosinophils > 2.7%, neutrophilic inflammation (NI) IS neutrophils > 65%, and mixed granulocytic inflammation (MGI) including both IS eosinophils > 2.7% and IS neutrophils > 65%. The association between the IS-UFP content and pulmonary function test (PFT) parameters was also tested.
Results: Patients with MGI had a distinct profile of particles in IS, which was characterized by the highest percentage of UFP (relative to larger particles) compared to patients with EI, NI, or normal IS cell count. Furthermore, EI and NI were found to have an interaction effect regarding the IS–UFP profile, as demonstrated by the significantly different IS–UFP profile of patients with MGI compared to the profile associated with EI and NI independently. Last, the profile of UFP in the IS samples was also correlated with patient PFT. Reduced forced mid-expiratory flow (FEF) 25–75 or FEV1 were correlated with a higher IS–UFP mean size. Reduced FEF25–75 was correlated with a lower IS–UFP concentration and percentage relative to larger particles.
Conclusions: To the best of my knowledge, this study is the first to report a distinct IS–UFP profile in patients with MGI, which suggest an interaction effect of EI and NI on the IS–UFP content. This finding may further support the consideration of MGI as a distinct inflammatory phenotype, beyond the simple combination of EI and NI independently. In addition, reduced PFT parameters were associated with a specific change in the IS–UFP profile. The results of this study may shed light on the use of IS–UFP content as a biomarker for lungs inflammation and functional impairment. Further prospective studies are needed to establish a cause and effect relationship between lungs inflammation and functional impairment to the IS–UFP content.
