Background: The neutrophil to lymphocyte ratio (NLR) has demonstrated prognostic value in various malignant conditions, including gastric adenocarcinoma. However, chemotherapy may affect NLR.

Objectives: To evaluate the prognostic value of NLR as an accessory decision-making tool in terms of operating patients after neoadjuvant chemotherapy in patients with resectable gastric cancer.

Methods: We collected oncologic, perioperative, and survival data of patients with gastric adenocarcinoma who underwent curative intent gastrectomy and D2 lymphadenectomy between 2009 and 2016. The NLR was calculated from preoperative laboratory tests and classified as high (> 4) and low (≤ 4). The t-test, chi-square, Kaplan-Meier analysis, and Cox multivariate regression models were used to assess associations of clinical, histologic, and hematological variables with survival.

Results: For 124 patients the median follow-up was 23 months (range 1–88). High NLR was associated with greater rate of local complication (r=0.268, P < 0.01). The rate of major complications (Clavien-Dindo ≥ 3) was higher in the high NLR group (28% vs. 9%, P = 0.022). Among the 53 patients who received neoadjuvant chemotherapy, those with low NLR had significantly improved disease-free survival (DFS) (49.7 vs. 27.7 months, P = 0.025). Low NLR was not significantly associated with overall survival (mean survival, 51.2 vs. 42.3 months, P = 0.19). Multivariate regression identified NLR group (P = 0.013), male gender (P = 0.04), and body mass index (P = 0.026) as independently associated with DFS.

Conclusions: Among gastric cancer patients planned for curative intent surgery who underwent neoadjuvant chemotherapy, NLR may have prognostic value, particularly regarding DFS and postoperative complications.

Background: The association between use of renin-angiotensin-aldosterone (RAAS) inhibitors and both SARS-CoV-2 infection and the development of severe COVID-19 has been presented in the recent medical literature with inconsistent results.

Objectives: To assess the association between RAAS inhibitor use and two outcomes: infection with SARS-CoV-2 (Model 1) and severe COVID-19 among those infected (Model 2).

Methods: We accessed used electronic health records of individuals from Israel who were receiving anti-hypertensive medications for this retrospective study. For Model 1 we used a case-control design. For Model 2 we used a cohort design. In both models, inverse probability weighting adjusted for identified confounders as part of doubly robust outcome regression.

Results: We tested 38,554 individuals for SARS-CoV-2 who had hypertension and were being treated with medication; 691 had a positive test result. Among those with a positive test, 119 developed severe illness. There was no association between RAAS inhibitor use and a positive test. Use of RAAS inhibitors was associated with a decreased risk for severe COVID-19 (adjusted odds ratio [OR] 0.47, 95% confidence interval [95%CI] 0.29–0.77) compared with users of non-RAAS anti-hypertensive medication. The association remained significant when use of angiotensin-converting-enzyme inhibitors (adjusted OR 0.46, 95%CI 0.27–0.77) and angiotensin II receptor blockers (adjusted OR 0.39, 95%CI 0.16–0.95) were analyzed separately.

Conclusions: Among individuals with hypertension using RAAS inhibitors, we found a lower risk of severe disease compared to those using non-RAAS anti-hypertensive medications. This finding suggests that RAAS inhibitors may have a protective effect on COVID-19 severity among individuals with medically treated hypertension.

Background: Isolated fallopian tube torsion (IFTT) is a rare gynecological entity and its diagnosis is challenging.

Objectives: To compare clinical characteristics, sonographic findings, surgical management, and outcomes of women with surgically verified IFTT compared to those diagnosed with adnexal torsion.

Methods: A retrospective case-control study in a university hospital was conducted. Thirty-four women with surgically verified IFTT between March 1991 and June 2017 were compared to 333 women diagnosed with adnexal torsion within the same time period.

Results: Both groups presented primarily with abdominal pain, which lasted longer prior to admission among the IFTT group (46.8 ± 39.0 vs. 30.0 ± 39.4 hours, P < 0.001). Higher rates of abdominal tenderness with or without peritoneal signs were found in the adnexal torsion group (90.3% vs. 70.6%, P < 0.001). Sonographic findings were similar; however, an increased rate of hydrosalpinx was found among the IFTT group (5.9% vs. 0.0%, P = 0.008). Suspected adnexal torsion was the main surgical indication in only 61.8% of IFTT cases compared with 79.0% in the adnexal torsion group (P = 0.02). Salpingectomy with or without cystectomy was more commonly performed in the IFTT group (35.3% vs. 1.5%, P < 0.001). The leading pathological findings among the IFTT group were hydrosalpinx and paraovarian cysts.

Conclusions: The clinical signs and symptoms of IFTT and adnexal torsion are similar. Although sonographic imaging demonstrating a paraovarian cyst or hydrosalpinx may be helpful in diagnosing IFTT, it is rarely done preoperatively.

Background: Recent studies have analyzed risk factors associated with complications after gastric cancer surgery using the Clavien-Dindo classification (CD). However, they have been based on Asian population cohorts (Chinese, Japanese, Korean).

Objectives: To prospectively analyze all post-gastrectomy complications according to severity using CD classification and identify postoperative risk factors and complications.

Methods: We analyzed all gastrectomies for gastric cancer performed 2009–2014. Recorded parameters included demographic data, existing co-morbidities, neo-adjuvant treatment, intra-operative findings, postoperative course, and histologic findings. Postoperative complications were graded using CD classification.

Results: The study comprised 112 patients who underwent gastrectomy. Mean age was 64.8 ± 12.8 years; 53 patients (47%) underwent gastrectomy, 37 (34%) total gastrectomy, and 22 (19%) total extended gastrectomy. All patients had D2 lymphadenectomy. The average number of retrieved lymph nodes was 35 ± 17. Severe complication rate (≥ IIIa) was 14% and mortality rate was 1.8%. In a univariate analysis, age > 65 years; ASA 3 or higher; chronic renal failure; multi-organ resection; and tumor, node, and metastases (TNM) stage ≥ IIIc were found to be significantly associated with CD complication grade > III (P = 0.01, P = 0.05, P = 0.04, P = 0.04, and P = 0.01, respectively). Multivariate regression analysis revealed advanced stage (≥ IIIc) and age > 65 years to be significant independent risk factors (P < 0.05).

Conclusions: Age > 65 and advanced stage (≥ IIIc) were the primary risk factors for complications of grade > III according to the CD classification following gastrectomy for gastric cancer.

Background: Male infertility is solely responsible for approximately 20% of all infertility in couples. Various factors have been proposed as having a negative effect on sperm quality; however, the reasons for the global decline in sperm parameters during the last few decades are still controversial. 

Objectives: To investigate the fluctuations of semen parameters (sperm concentration, motility, and morphology) in three sperm quality groups and to examine the trends of those parameters in the same men over time. 

Results: Our data showed deterioration in all semen parameters assessed in the group of men originally considered as having normal semen values according to the 2010 criteria of the World Health Organization. In contrast, we found significant improvement over time in all semen parameters in the group of men with severe oligo-terato-asthenozoospermia. 

Conclusions: Our results suggest that, although there were changes in sperm quality over time in the groups assessed, the clinical significance is negligible and does not necessarily justify a change in the therapeutic approach to infertility or sperm cryopreservation. 

 

Background: The management of sexual assault victims comprises complex medical, psychological, social and judicial care that was previously provided by various disciplines at several distant locations. This novel concept is the delivery of comprehensive care to victims of sexual assault at one location 24 hours a day.

Objectives: To describe the characteristics of sexual assault victims, their assailants, the assault and the treatment, and provide descriptive data on the evidentiary examination.

Methods: We performed a retrospective analysis of the charts of all sexual assault victims presenting to the Regional Israeli Center for Care of Sexual Assault Victims between October 2000 and July 2010. The center, the first in Israel, provides comprehensive care to victims of sexual assault in one location 24 hours a day using a multidisciplinary approach.

Results: The study group comprised 1992 subjects; 91.5% of the victims were females and 8.5% were males, and the age ranged from 1 to 88 years (mean age 22.3 years). Of the 1992 victims, 1635 were single (82.2%), 195 were divorced (9.8%), 141 were married (7.1%), 18 were widowed (0.9%) and 3 were unspecified. The assailant was a stranger in 794 (39.8%) of the cases, someone familiar to the victim in 786 cases (39.0%), a partner in 127 cases (6.4%), a family member in 117 cases (5.9%), someone met via the internet in 53 cases (2.7%), an authority figure in 39 cases (2.0%), and unspecified in 76 (3.9%). In the majority of cases the attack occurred either in the evening or at night (71.7%).

Conclusions: We identified several risk factors for sexual assault that can be used in prevention programs. The sexual assault victim in our study tended to be a young, single woman who was attacked by a familiar assailant in the evening or at night. Our center provides comprehensive care to victims 24 hours a day at one location and includes a team of forensic, psychological, physical and legal specialists.
 

Background: Leukotriene antagonist therapy in asthmatic patients alleviates symptoms and improves exercise tolerance, however the effect of these drugs on bronchial provocation tests and exhaled nitric oxide levels are less clearly established.

Objective: To determine the effect of montelukast treatment on airway hyperresponsiveness to exercise, methacholine and adenosine-5’-monophosphate and on exhaled nitric oxide levels in steroid-naive asthmatics.

Methods: Following a 2 week run-in period, 20 mild to moderate asthmatics were enrolled in an open label 6 week trial of oral montelukast-sodium therapy. Bronchial hyperreactivity (exercise, methacholine and adenosine-5’-monophosphate challenges) and exhaled nitric oxide levels were measured before and after the 6 week period.

Results: Montelukast treatment resulted in a significant improvement in exercise tolerance: median DFEV₁ 20.0% (range 0–50) prior to treatment vs. 15.0% (range 0–50) post-treatment (P = 0.029). A significant difference was also observed for exhaled NO[1] following therapy: median NO 16.0 ppb (range 7–41) vs. 13.0 (range 4.8–26) (P = 0.016). No change was seen in baseline lung function tests (FEV₁, MEF₅₀) or in the bronchial responsiveness (PC₂₀) for methacholine and adenosine-5’-monophosphate.

Conclusions: This study demonstrates that the leukotriene antagonist, montelukast-sodium, reduces bronchial hyperreactivity in response to exercise and reduces exhaled nitric oxide levels but has little effect on bronchial responsiveness to methacholine and adenosine challenges.
