Proximal Urethrostomy Versus Urethroplasty for Complex Urethral Strictures.

Background: The optimal treatment for complex urethral stricture (CUS) is yet to be determined. Comparisons of methods based on validated questionnaires or objective outcome measures are lacking. Objective: To compare proximal urethrostomy and urethroplasty for CUS using objective measures and validated questionnaires, and to evaluate trends in subgroups of patients who underwent proximal urethrostomy as the intended definitive treatment versus first-stage urethroplasty. Design setting and participants: We identified all patients who underwent proximal urethrostomy at our center from 2004 to 2021. The control group comprised patients who underwent urethroplasty for CUS (strictures >6 cm, recurrent posturethroplasty strictures, or CUS due to lichen sclerosus or past hypospadias surgery). Outcome measurements and statistical analysis: The primary outcome was a recurrent stricture at a minimal follow-up of 1 yr. The secondary outcomes included validated questionnaires, uroflowmetry, and residual urine volume. Survival was compared by a Kaplan-Meier analysis. Results and limitations: The study included 57 proximal urethrostomy and 75 urethroplasty patients. Results for these two groups were as follows: the cumulative incidence of stricture recurrence over a median follow-up of 46 mo was 22.6% for proximal urethrostomy versus 36.2% for urethroplasty (p = 0.106); no statistically significant differences were observed between groups in terms of postoperative quality of urination or life, satisfaction with outcome, and erectile function. Both groups had a significant improvement in urinary flow after surgery (19.65 vs 20.29 ml/s), with no difference between the groups (p = 0.796); the proximal urethrostomy group had a significant improvement in postvoid residual after surgery, but there was no difference between the groups in the last follow-up visit (79.16 vs 52.03 ml; p = 0.245). A subgroup analysis of the proximal urethrostomy group showed no significant differences in cumulative primary or secondary outcomes. Limitations included the retrospective design and the relatively small study population. Conclusions: Comparisons of the two groups revealed no significant differences in stricture recurrence, results of validated questionnaires, or objective measures of urination. Patient summary: Proximal urethrostomy is equivalent to urethral reconstruction, and it should be offered as a viable solution for complex urethral stricture.

The impact of germline BRCA pathogenic variants in locally advanced, triple negative breast cancer treated with platinum-based neoadjuvant chemotherapy.

BACKGROUND: Whether germline BRCA (gBRCA) pathogenic variants (PV) affect prognosis of women with triple negative breast cancer (TNBC) and whether it has implications for treatment decisions in the neoadjuvant setting is unclear. METHODS: This is a retrospective two-center cohort study comprising all women with early stage TNBC who have completed genetic testing and were treated with neoadjuvant dose-dense doxorubicin and cyclophosphamide followed by paclitaxel and carboplatin. All eligible patients treated between 10.2014 and 3.2020 were included. Data on clinico-pathological, pathological response, overall survival (OS) and disease-free survival (DFS) were evaluated. Differences in clinico-pathological features and outcomes were analyzed according to gBRCA status. RESULTS: Sixty-four women were included in the final analysis, of which 31 had gBRCA PV (gBRCA carriers) and 33 were gBRCA wild-type. Clinico-pathological characteristics were similar between both groups. The odds for pathological complete response (pCR) were significantly higher in gBRCA carriers (74.2%) compared to BRCA wild-type women (48.5%), p = 0.035. At a median follow-up of 30 months, gBRCA carriers had significantly favorable OS (HR = 8.64, 95% CI 1.08-69.21, p = 0.042). The difference in DFS did not reach statistical significance (HR = 7.4, 95% CI 0.91-60.27, p = 0.062). The favorable OS for gBRCA carriers remained significant in multivariate analysis (p = 0.029) and was noted regardless of pathological response (p = 0.018). CONCLUSION: Compared to wild-type, gBRCA carriers with locally advanced TNBC treated with neoadjuvant chemotherapy containing carboplatin had a higher pCR rate and better outcomes. These results strengthen the contention that gBRCA status should be considered when tailoring treatment decisions in women with locally advanced TNBC.

The association between sonographic common bile duct dilatation and outcomes in emergency department patients with cholangitis.

BACKGROUND: The presentation of the patient with acute cholangitis (AC) ranges from mild illness to life-threatening shock. Therefore, prompt diagnosis and treatment are critical. Abdominal ultrasound (US) is the imaging of choice to locate bile duct dilatation. Other modalities include abdominal computed tomography (CT) or endoscopic retrograde cholangiopancreatography (ERCP). OBJECTIVES: To determine whether sonographic common bile duct dilatation in emergency department (ED) patients with AC predicts outcomes including sepsis, hospital length of stay (LOS), admission to the intensive care unit (ICU), time to ERCP, and mortality. METHODS: Electronic medical records of all patients hospitalized in a tertiary care medical center between July 2012-February 2021 with a discharge diagnosis of cholangitis were assessed. Patients were dichotomously classified as CBD dilated or CBD non-dilated based on ultrasound. Dilation was defined as CBD larger than 6 mm in patients younger than 60 or larger than 6 mm + 1 mm per decade in patients over 60. RESULTS: The study included 271 patients- 172 with CBD dilation versus 99 without. Mean LOS was 9.92 days for those with a dilated CBD versus 13.4 days without. The mean time to ERCP was 4.26 days for those with a dilated CBD versus 6.56 days without. Sepsis, mortality, and ICU admission were scarce and there was no statistically significant difference between the cohorts. CONCLUSION: Patients with a dilated CBD per the abdominal US performed during the patient's ED stay, underwent ERCP earlier, and were hospitalized fewer days than patients without CBD dilation.

Acute Kidney Injury in Very Low Birth Weight Infants: A Major Morbidity and Mortality Risk Factor.

BACKGROUND AND OBJECTIVES: Very low birth weight (VLBW) infants are at high risk of developing acute kidney injury (AKI), presumably secondary to low kidney reserves, stressful postnatal events, and drug exposures. Our study aimed to identify the prevalence, risk factors, and outcomes associated with AKI in VLBW infants. STUDY DESIGN: Records of all VLBW infants admitted to two medical campuses between January 2019 and June 2020 were retrospectively reviewed. AKI was classified using the modified KDIGO definition to include only serum creatinine. Risk factors and composite outcomes were compared between infants with and without AKI. We evaluated the main predictors of AKI and death with forward stepwise regression analysis. RESULTS: 152 VLBW infants were enrolled. 21% of them developed AKI. Based on the multivariable analysis, the most significant predictors of AKI were the use of vasopressors, patent ductus arteriosus, and bloodstream infection. AKI had a strong and independent association with neonatal mortality. CONCLUSIONS: AKI is common in VLBW infants and is a significant risk factor for mortality. Efforts to prevent AKI are necessary to prevent its harmful effects.

Outcome predictors and patient progress following delivery in pregnant and postpartum patients with severe COVID-19 pneumonitis in intensive care units in Israel (OB-COVICU): a nationwide cohort study.

BACKGROUND: A key unresolved controversy in severe COVID-19 pneumonitis in pregnancy is the optimum timing of delivery and whether delivery improves or worsens maternal outcomes. We aimed to assess clinical data on every intensive care unit (ICU) day for pregnant and postpartum women admitted to the ICU with COVID-19, with a particular focus on the days preceding and following delivery. METHODS: In this multicentre, nationwide, prospective and retrospective cohort study, we evaluated all pregnant women who were admitted to an ICU in Israel with severe COVID-19 pneumonitis from the 13th week of gestation to the 1st week postpartum. We excluded pregnant patients in which the ICU admission was unrelated to severe COVID-19 pneumonitis. We assessed maternal and neonatal outcomes and longitudinal clinical and laboratory ICU data. The primary overall outcome was maternal outcome (worst of the following: no invasive positive pressure ventilation [IPPV], use of IPPV, use of extracorporeal membrane oxygenation [ECMO], or death). The primary longitudinal outcome was Sequential Organ Failure Assessment (SOFA) score, and the secondary longitudinal outcome was the novel PORCH (positive end-expiratory pressure [PEEP], oxygenation, respiratory support, chest x-ray, haemodynamic support) score. Patients were classified into four groups: no-delivery (pregnant at admission and no delivery during the ICU stay), postpartum (ICU admission ≥1 day after delivery), delivery-critical (pregnant at admission and receiving or at high risk of requiring IPPV at the time of delivery), or delivery-non-critical (pregnant at admission and not critically ill at the time of delivery). FINDINGS: From Feb 1, 2020, to Jan 31, 2022, 84 patients were analysed: 34 patients in the no-delivery group, four in postpartum, 32 in delivery-critical, and 14 in delivery-non-critical. The delivery-critical and postpartum groups had worse outcomes than the other groups: 26 (81%) of 32 patients in the delivery-critical group and four (100%) of four patients in the postpartum group required IPPV; 12 (38%) and three (75%) patients required ECMO, and one (3%) and two (50%) patients died, respectively. The delivery-non-critical and no-delivery groups had far better outcomes than other groups: six (18%) of 34 patients and two (14%) of 14 patients required IPPV, respectively; no patients required ECMO or died. Oxygen saturation (SpO2), SpO2 to fraction of inspired oxygen (FiO2) ratio (S/F ratio), partial pressure of arterial oxygen to FiO2 ratio (P/F ratio), ROX index (S/F ratio divided by respiratory rate), and SOFA and PORCH scores were all highly predictive for adverse maternal outcome (p<0·0001). The delivery-critical group deteriorated on the day of delivery, continued to deteriorate throughout the ICU stay, and took longer to recover (ICU duration, Mantel-Cox p<0·0001), whereas the delivery-non-critical group improved rapidly following delivery. The day of delivery was a significant covariate for PORCH (p<0·0001) but not SOFA (p=0·09) scores. INTERPRETATION: In patients who underwent delivery during their ICU stay, maternal outcome deteriorated following delivery among those defined as critical compared with non-critical patients, who improved following delivery. Interventional delivery should be considered for maternal indications before patients deteriorate and require mechanical ventilation. FUNDING: None.

Dermatological adverse events under programmed cell death-1 inhibitors as a prognostic marker in metastatic melanoma.

Melanoma is widely treated with programmed cell death-1 (PD-1) inhibitors. As part of their anti-tumor immunity effect, they increase the susceptibility to cutaneous immune-related adverse events (cIRAE) among other autoimmune effects. To characterize the manifestations of cIRAE in melanoma patients treated with PD-1 inhibitors, and evaluate the correlation with tumor response. A retrospective study of 95 metastatic malignant melanoma patients treated with PD-1 inhibitors at the Hadassah Medical Center during 2013-2016. The most common cIRAE was pruritus reported by 39 (41%) patients. All other cIRAE were noted in 34 patients (35.8%), of which the most common cutaneous manifestation was vitiligo, demonstrated in 17 patients (17.9%) followed by various rashes (7.4%, including erythema multiforme, oral lichen planus, photosensitive rash, insect bite-like reaction, and urticaria), psoriasiform rash (3.2%), bullous pemphigoid (3.2%), and eczema (1%). Interestingly, higher response rates to immunotherapy were demonstrated in patients who developed pruritus (85%) and cIRAE (88%), with lower mortality rates in the cIRAE group (38.2%) versus the non-cIRAE group (70.5%, p = 0.002). cIRAE are common among malignant melanoma patients treated with PD-1 inhibitors and may be a marker for favorable prognosis.

Endoscopic versus fluoroscopic esophageal dilatations in children with esophageal strictures: 10-year experience.

Esophageal strictures in children may cause dysphagia, choking during feeds, and failure to thrive. They can be treated by balloon dilatations, either under endoscopic or fluoroscopic guidance; there is no literature comparing the methods. Retrospective review of the medical records of children (0-18 years) who were treated with balloon dilatations between 2010 and 2020. The primary outcome was the number of dilatation sessions required until clinical success after 3 months. Secondary outcomes were long-term success at 12 months, and complications of bleeding and perforation. Forty-six patients underwent 174 dilatation sessions. Success rates in the endoscopy and fluoroscopy groups were similar: 62% versus 67% (p = 0.454) at 3 months and 57% versus 67% (p = 0.721) at 12 months. Complication rate was lower in the endoscopy group (0% vs. 15%, p < 0.001). Both endoscopic and radiologic-guided balloon dilatations were shown to be equally effective, but endoscopic guidance had fewer complications.

Amniotic fluid biomarkers predict the severity of congenital cytomegalovirus infection.

BACKGROUNDCytomegalovirus (CMV) is the most common intrauterine infection, leading to infant brain damage. Prognostic assessment of CMV-infected fetuses has remained an ongoing challenge in prenatal care, in the absence of established prenatal biomarkers of congenital CMV (cCMV) infection severity. We aimed to identify prognostic biomarkers of cCMV-related fetal brain injury.METHODSWe performed global proteome analysis of mid-gestation amniotic fluid samples, comparing amniotic fluid of fetuses with severe cCMV with that of asymptomatic CMV-infected fetuses. The levels of selected differentially excreted proteins were further determined by specific immunoassays.RESULTSUsing unbiased proteome analysis in a discovery cohort, we identified amniotic fluid proteins related to inflammation and neurological disease pathways, which demonstrated distinct abundance in fetuses with severe cCMV. Amniotic fluid levels of 2 of these proteins - the immunomodulatory proteins retinoic acid receptor responder 2 (chemerin) and galectin-3-binding protein (Gal-3BP) - were highly predictive of the severity of cCMV in an independent validation cohort, differentiating between fetuses with severe (n = 17) and asymptomatic (n = 26) cCMV, with 100%-93.8% positive predictive value, and 92.9%-92.6% negative predictive value (for chemerin and Gal-3BP, respectively). CONCLUSIONAnalysis of chemerin and Gal-3BP levels in mid-gestation amniotic fluids could be used in the clinical setting to profoundly improve the prognostic assessment of CMV-infected fetuses.FUNDINGIsrael Science Foundation (530/18 and IPMP 3432/19); Research Fund - Hadassah Medical Organization.

QRS Narrowing Following CRT Implantation: Predictors, Dynamics, and Association with Improved Long-Term Outcome.

Background: Heart failure (HF) patients with wide QRS often benefit from cardiac resynchronization therapy (CRT), although QRS narrowing does not always occur. The current study investigates the incidence and predictors for QRS narrowing following CRT and its long-term impact on clinical outcomes. Methods: Among individuals undergoing clinically indicated CRT, pre-and post-implantation electrocardiographs were meticulously analyzed for QRS duration change. All-cause mortality and the composite of mortality and HF hospitalizations were retrieved. Results: For 104 patients, mean age 67 years, 25% females, QRS narrowed within days by 20.2 ± 24.7 ms. In 55/104 (53%) QRS narrowed by ≥20 ms ("acute narrowing"). Female gender and baseline QRS predicted acute narrowing. Acute narrowing persisted for 1−6 weeks in 18/20 (90%) and 3−12 months in 21/31 (68%) of patients. During the average follow-up of 41 months, 29/104 (28%) died and 50/104 (48%) met the composite outcome. In a multivariable analysis including comorbidities and cardiac history, prolonged baseline PR interval (HR 1.015, CI 1.008−1.021, p < 0.001) and acute narrowing < 20 ms (HR 3.243, CI 1.593−6.603, p = 0.001) were significant and independent predictors for the composite outcome. Conclusions: Post-CRT acute QRS narrowing ≥ 20 ms is independently associated with favorable long-term outcomes and might be considered as a novel measure for procedural success.

Preoperative evaluation of pulmonary hypertension in lung transplant candidates: echocardiography versus right heart catheterization.

BACKGROUND: Right heart catheterization (RHC) and echocardiography are both routinely used for pulmonary artery systolic pressure (PASP) assessment in lung transplantation (LT) candidates, although this is not mandated by current guidelines. We aimed to explore the performance of echocardiographic PASP as an indicator of pulmonary hypertension in LT candidates, in order to assess the necessity of RHC. METHODS: From a retrospective registry of 393 LT candidates undergoing RHC and echocardiography during 2015-2019, patients were assessed for the presence of pulmonary hypertension (PH), defined as mean pulmonary artery pressure (mPAP) above 20 mmHg, according to two methods-echocardiography and RHC. The primary outcome was the correlation between the PASP estimated by echocardiography to that measured by RHC. Secondary outcomes were the prediction value of the echocardiographic evaluation and its accuracy. RESULTS: The mean value of PASP estimated by echocardiography was 49.5 ± 20.0 mmHg, compared to 42.5 ± 18.0 mmHg measured by RHC. The correlation between the two measurements was moderate (Pearson's correlation: r = 0.609, p < 0.01). Echocardiography PASP measurements were moderately discriminative to diagnose PH, with an area under the curve (AUC) of 0.72 (95% CI 0.66-0.77). Echocardiographic overestimation of PASP of more than 10 mmHg was found in 35.0% of the patients, and underestimation was found in 11.6% of the patients. CONCLUSION: In the pre-surgical evaluation of LT candidates, echocardiographic estimation of PASP had moderate correlation and limited accuracy compared to the PASP measured by RHC. We thus recommend performing routine RHC to all LT candidates, regardless of the echocardiographic estimation of PASP.

Intellectually disabled patients' intensive care admission characteristics, weaning from mechanical ventilation, and sedative drug use: a single-center retrospective case-control study.

BACKGROUND: Intellectually disabled (ID) patients present unique therapeutic challenges. We aimed to describe the characteristics of ID patients admitted to a general intensive care unit (ICU). RESULTS: We conducted a retrospective cohort study comparing critically ill adult ID patients to matched patients without ID (1:2 ratio) in a single ICU (2010-2020). The main outcome measure was mortality. Secondary outcomes included complications during admission and characteristics of weaning from mechanical ventilation. The study and control groups were randomly selected based on similar age and sex. ID patients nonetheless had an average APACHE score of 18.5 ± 8.7 vs. 13.4 ± 8.5 in controls (p < 0.001). ID patients had more hematological (p = 0.04), endocrinological (p < 0.001) and neurological (p = 0.004) comorbidities and used more psychiatric medication before admission. No difference was found in mortality rates. Differences were found as there were more secondary complications, such as pulmonary and sepsis (p < 0.03), frequent requirement of vasopressors (p = 0.001), significantly higher intubation rates with more weaning attempts, tracheostomies and longer ICU and hospital admissions (p < 0.019). CONCLUSIONS: Critically ill adult ID may have more comorbidities and be sicker at the time of admission compared to their age- and sex-matched counterparts. They require more supportive treatment and their weaning from mechanical ventilation may be more challenging.

The Timing of Limb Amputation in Nontraumatic Patients: Impact on Mortality and Postoperative Complication Rates.

Diabetes and peripheral vascular diseases are accompanied frequently by lower limb ischemia and in minority, need for amputation, as a treatment of last resort. Even after a decision has been made regarding amputation, the procedures are often repeatedly postponed due to more urgent surgeries and lack of operating room availability. This study assessed the possible relationship between the duration of time inpatients wait for semiurgent amputations and the incidence of postamputation complications. A retrospective cohort, including all 360 adult patients who underwent nontraumatic limb amputation due to an ischemic/gangrenous/infected foot in a single center during an 11-year period (2007-2017). Most (96%) of the procedures were major amputations. The mean waiting time until amputation was 3 ± 5 days. Mortality during hospitalization occurred in 101 (28%) patients and re-amputation in 38 (11%). The duration of antibiotic treatment was 11 ± 14 days. The rate of sepsis was 30% (107/360). There was no significant difference between the duration of time until amputation and mortality during hospitalization: among those who waited ≤48 hours, the mortality rate was 27% (60/224) and among those who waited >48 hours 30% (41/136) (p = .5). Patients waiting ≤48 hours had higher re-amputation rates than those waiting >48 (31/223 (14%) vs 7/136 (5%), p = .009). Mortality was associated significantly to patients' age and renal function. Correlation was found between the waiting time until amputation (≤48 or >48 hours) and the rates of in-hospital mortality, sepsis, duration of antibiotic treatment and overall duration of hospitalization. Re-amputation rate was higher in group with the shorter waiting time. This correlation may be explained by the fact that patients who needed urgent amputation had a more extensive and severe disease, and thus tended to require more re-amputation operations.

Outcomes of sublobar resection vs lobectomy for invasive clinical stage T1N0 non-small-cell lung cancer: A propensity-match analysis.

BACKGROUND: The role of sub lobar resection (SLR; either segmentectomy or wedge resection) vs lobectomy (LBCT) for invasive clinical stage T1N0 non-small-cell-lung-cancer (NSCLC) has not been fully established yet. AIM: We aimed to characterize the preoperative parameters leading to selecting SLR and compare the overall survival (OS) and disease-free survival (DFS) of these two surgical approaches. METHODS: Clinical data on 162 patients (LBCT-107; SLR-55) were prospectively entered in our departmental database. Preoperative parameters associated with the performance of SLR were identified using univariate and multivariate cox regression analysis. The Kaplan-Meier method was used to compute OS and DFS. Comparison between LBCT and SLR groups and 32 propensity-matched groups was performed using Log-rank test. RESULTS: Median follow-up time for the LBCT and SLR groups was 4.76 (Inter-quartile range [IQR] 2.96 to 8.23) and 3.38 (IQR 2.9 to 6.19) years respectively. OS and DFS rates were similar between the two groups in the entire cohort (OS-LBCT vs SLR P = .853, DSF-LBCT vs SLR P = .653) and after propensity matching (OS-LBCT vs SLR P = .563 DSF-LBCT vs SLR P = .632). Specifically, Two- and five-year OS rates for LBCT and SLR were 90.6.% vs 92.7%, 71.8% vs 75.9% respectively. Independent predictors of selecting for SLR included older age (P < .001), reduced FEV1% (P = .026), smaller tumor size (P = .025), smaller invasive component (P = .021) and higher American Society of Anesthesiology scores (P = .014). CONCLUSIONS: In 162 consecutive and 32 matched cases, SLR and lobar resection had similar overall and disease-free survival rates. SLR may be considered as a reasonable oncological procedure in carefully selected T1N0 NSCLC patients that present with multiple comorbidities and relatively small tumors.

Severity of shock, rate of physiological stabilization and organ failure in healthy women admitted to the intensive care unit following major peripartum hemorrhage: A retrospective, descriptive study.

PURPOSE: To describe shock severity, physiological stabilization and organ failure in healthy women admitted to the intensive care unit (ICU) after major peripartum hemorrhage (PPH). MATERIALS AND METHODS: Retrospective, descriptive, single center study. RESULTS: Twenty-nine women median age 33 years (interquartile range [IQR] 30-36) and gravidity 5 pregnancies (IQR 3-9) were studied. One woman died. The median maternal admission hematocrit was 28.8 (IQR 25.7-32.4). Median transfusion rates were nine units of packed red blood cells (IQR 7-12.25), eight fresh frozen plasma (IQR 6-12), 17 platelets (IQR 10-22) and 15 cryoprecipitate (IQR 9.75-20). Blood pressure dropped significantly in the six hours following ICU admission. Nonetheless, lactate decreased from 3.23 mmol/L to 1.54 mmol/L within 24 h of ICU admission, renal and pulmonary function were unaffected and coagulopathy was never observed. Two-thirds of the women underwent hysterectomy. One-third underwent repeated surgery. The median length of ICU stay was <48 h and that of mechanical ventilation was <24 h. Increased transfusion rates correlated with lengthier ICU admission (p ≤ 0.01 regardless of blood product). CONCLUSIONS: Ongoing hemorrhage in women with severe PPH manifests subtly and often requires active intervention. Hemorrhage control is required to achieve physiological stabilization and minimize organ damage.

Community Rehabilitation and Hospitalizations Among People With Chronic Psychotic Disorder: Is There a Differential Association by Co-occurring Substance Use Disorder?

Objective: Co-occurrence of chronic psychotic disorders and substance use disorder (SUD) is clinically challenging and increasingly prevalent. In 2000, legislation was passed in Israel to foster rehabilitation and integration in the community of persons with mental health disorders. In 2010, the need to allocate resources for patients with these co-occurring disorders (COD) was officially recognized. Yet, most rehabilitation services were not specifically designed for COD. This study examines the relationship between duration of community rehabilitation and number of psychiatric hospitalization days among persons with/without COD in Israel. Methods: Data from the National Psychiatric Case Register on 18,684 adults with schizophrenia/schizoaffective disorders hospitalized in 1963-2016, was merged with data from the Israel Mental Rehabilitation Register. Associations and interactions between COD-status (COD/non-COD), time-period (Period1: 2001-2009, Period2: 2010-2016), duration of housing or vocational rehabilitation on hospitalization days per year were analyzed using repeated-measures ANOVA. Results: The proportion of non-COD chronic psychotic patients who received rehabilitation services increased from 56% in Period1 to 63% in Period2, as it did among COD patients-from 30 to 35%. The proportion of non-COD patients who received longer-duration vocational rehabilitation (≥1 year) was significantly higher (43%) than among COD patients (28%) in both time periods. For housing rehabilitation, these proportions were 79 and 68%, respectively. Persons with COD experienced more hospitalization days annually than non-COD patients. Duration of rehabilitation (less/more than a year) was inversely associated with annual number of hospitalization days (p < 0.0001). This pattern was noted in both COD and non-COD groups and remained significant after controlling for age, sex, COD group, percent of hospitalizations with SUD, and age at first hospitalization. Conclusions: COD patients with prolonged rehabilitation seemingly achieve long-term clinical improvement similar to non-COD patients, despite most rehabilitation settings in Israel not being designed for COD patients. Yet, COD patients receive overall less rehabilitation services and for shorter periods than non-COD patients. Long-term rehabilitation services should be provided to COD patients, who may need more time to commit to treatment. To achieve better long-term mental health improvements, a continued expansion of community-based integrative treatment and rehabilitation services for COD patients is needed in Israel.

Evaluation of alfaxalone and midazolam with or without flumazenil reversal in Egyptian fruit bats (Rousettus aegyptiacus).

OBJECTIVES: To evaluate alfaxalone-midazolam anesthesia in Egyptian fruit bats (Rousettus aegyptiacus) and the effect of flumazenil administration on recovery time and quality. STUDY DESIGN: Randomized, blinded, crossover and controlled, experimental trial. ANIMALS: A total of 10 male Egyptian fruit bats. METHODS: Bats were anesthetized with alfaxalone (15 mg kg-1) and midazolam (2 mg kg-1) administered subcutaneously. During anesthesia, vital signs, muscle tone and reflexes were monitored every 10 minutes. Flumazenil (0.3 mg kg-1) or saline at an equal volume was administered subcutaneously 60 minutes after anesthetic administration. Time to induction, time to first movement and recovery time (flying) were measured. Quality of induction, anesthesia and recovery were assessed on a 1-3 scale (1, poor; 2, good; 3, excellent). RESULTS: Time to induction was 4.2 ± 1.9 minutes (mean ± standard deviation), with median quality score of 2 (range, 1-3). Anesthesia quality score was 3 (1-3). During anesthesia, heart rate and respiratory frequency decreased significantly and penis relaxation, indicating muscle tone, increased significantly. Administration of flumazenil significantly reduced mean recovery time compared with saline (10 ± 5 versus 45 ± 17 minutes, respectively), and significantly improved the quality of recovery [2.5 (2-3) versus 1 (1-2), respectively]. CONCLUSIONS AND CLINICAL RELEVANCE: Alfaxalone-midazolam anesthesia resulted in good induction, muscle relaxation and sufficient anesthesia to perform routine diagnostic and therapeutic procedures for approximately 40 minutes. Reversal of midazolam with flumazenil is recommended, resulting in quicker and better recovery.

Assessment of infections rate due to community-acquired Methicillin-resistant Staphylococcus aureus and evaluation of risk factors in the paediatric population.

AIM: We aimed at assessing the frequency of Community-acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA) infections, identifying its risk factors and evaluating resistance patterns of Staphylococcus aureus to various antibiotics in order to recommend the optimal empirical treatment for suspected Staphylococcus aureus infections. METHODS: We reviewed the medical records of children who were treated at Shaare Zedek medical centre, located in Jerusalem, Israel, over the years 2008-2019 and had a positive culture for Staphylococcus aureus. Patients with CA-MRSA infections were compared with Methicillin-susceptible Staphylococcus aureus (CA-MSSA) infections. RESULTS: In this study, 620 paediatric patients were included. The number of children in the CA-MRSA study group was 124, while the MSSA control group consisted of 496 children. Risk factors for CA-MRSA infections included young age (1-5 years), female sex, Arab ethnicity and residence in East Jerusalem. The incidence of CA-MRSA increased over the past decade, with an average of 11.2%. An increase in MSSA resistance to clindamycin was noted while Trimethoprim-Sulphamethoxazole resistance remained low. CONCLUSION: The incidence of CA-MRSA in Jerusalem was rising, along with changes in resistance patterns of both MSSA and MRSA to various antibiotic agents. In order to optimise empirical treatment for suspected staphylococcal infection, continued monitoring of CA-MRSA prevalence and resistance rates is essential.

Parameters associated with sperm quality prior to chemotherapy in lymphoma patients.

Sperm quality in lymphoma patients may be reduced even prior to initiation of chemotherapy. The objective of this study was to examine the relationship between lymphoma prognostic factors and sperm quality prior to chemotherapy. A retrospective cohort study was conducted in a Hadassah Medical Center sperm bank and the Hematology department. The cohort included 101 Hodgkin's and 90 non-Hodgkin's lymphoma patients that underwent sperm cryopreservation before chemotherapy between 1998 and 2015. Known lymphoma prognostic factors were compared between patients with normal and impaired sperm parameters. The Prognostic Score Ratio (PSR), an index representing the number of negative lymphoma prognostic measures that found in a lymphoma patient, was additionally calculated and compared between the groups. Among the prognostic factors of lymphoma, the following factors were found to be associated with impaired sperm parameters-low albumin (p < 0.001) and haemoglobin (p < 0.001) levels, B symptoms (p = 0.021) and PSR (p < 0.001). Logistic regression showed significant association of albumin and haemoglobin with reduced sperm quality (OR = 2.7 and OR = 13.5, p < 0.05; respectively). To conclude, low albumin and haemoglobin levels are related to reduced sperm quality. The linkage between these prognostic factors and sperm quality may be related to a general inflammatory status.

Cluster analysis based clinical profiling of Idiopathic Pulmonary Fibrosis patients according to comorbidities evident prior to diagnosis: a single-center observational study.

BACKGROUND: The characterization and clinical profiling of people affected by Idiopathic Pulmonary Fibrosis (IPF), based on clinical events occurring prior to the diagnosis of the fibrotic disease, may facilitate the understanding of events and comorbidities that occur before the diagnosis of IPF and aid in identifying patients at an earlier stage of the disease. METHODS: In this observational study, a cohort of 96 patients, obtained from a community-based pulmonary clinic, were studied retrospectively. These patients were diagnosed with IPF between January 2008 and November 2016, based on findings on lung biopsy and/or high-resolution CT. Using clinical data obtained within the five years before diagnosis and the two-step method of cluster analysis, patients were assigned to one of four groups. The distribution of clinical characteristics and comorbidities present prior to diagnosis was analyzed among the clusters. RESULTS: Cluster 1 is composed of male patients, smokers, with ischemic heart disease. Cluster 2 is composed of male patients, smokers with dyspnea at rest, dry cough and prevalent emphysema. Cluster 3 is composed of male patients without other significant comorbidities, half of whom had dyspnea at exertion. Cluster 4 includes female patients only, most of whom never-smokers and the largest portion of patients with hypothyroidism. The majority of patients had basal end-inspiratory crackles at time of diagnosis, equally distributed among clusters. CONCLUSION: Different clinical phenotypes of IPF emerge years before time of diagnosis and if confirmed in larger cohorts may help in forming diagnostic algorithms that would allow earlier diagnosis of IPF.
