ABSTRACT

Objective: To explore the efficacy of intravenous thrombolysis with tenecteplase (TNK) in the treatment of branch atheromatous disease (BAD). Methods: A total of 148 BAD patients hospitalized in the stroke center of Zhengzhou People’s Hospital from January 2020 to March 2023 were retrospectively included. According to whether TNK was used for treatment, the patients were divided into the TNK group (52 cases) and the control group (96 cases). The propensity score matching (PSM) method was used to eliminate baseline differences between the two groups, and 46 pairs were successfully matched. Early neurological deterioration (END) was defined as an increase in the national Institutes of Health Stroke Scale (NIHSS) scores within 7 days of stroke≥2. The 90-day modified Rankin Scale (mRS) was used to compare the long-term efficacy between the two groups. A binary logistic regression model was used to analyze the influencing factors of clinical outcomes in patients with BAD. Results: Among the 92 patients, 62 were males and 30 were females, with an average age of (61.0±9.5) years. After PSM, there were statistically significant differences in NIHSS score at discharge [2 (0, 4) vs 4 (3, 8)] and length of hospital stay [9 (6, 13) d vs 11 (9, 14) d] (both P<0.05) between the two groups. The proportion of mRS 0-2 in TNK group was higher than that in the control group [82.6%(38/46) vs 60.8%(28/46)], while the proportion of END and mRS≥4 was lower than that in the control group [10.8%(5/46) vs 30.4%(14/46); 8.7%(4/46) vs 26.0%(12/46)], with statistically significant differences (P<0.05). The 90-day mortality in the control group was 2.2% (1/46), while no death was detected in the TNK group. Conclusion: Intravenous thrombolysis therapy with TNK can not only increase the proportion of 90-day mRS 0-2 in BAD patients, but also reduce the incidence of END.

ABSTRACT

Objective: To investigate the clinical, biological and prognostic characteristics of leukemic non-nodal mantle cell lymphoma (nnMCL). Methods: The clinical data of 14 patients with nnMCL and 238 patients with classical mantle cell lymphoma (cMCL) in Blood Diseases Hospital, Chinese Academy of Medical Sciences from November 2000 to October 2020 were retrospectively analyzed. Among the 14 patients with nnMCL, there were 9 males and 5 females, with the age [M (Q₁, Q₃)] of 57.5 (52.3, 67.0) years. Among the 238 patients with cMCL, there were 187 males and 51 females, with the age of 58.0 (51.0, 65.3) years. The clinical and biological characteristics of the two groups were recorded and compared. Follow-up and efficacy evaluation were conducted by re-examination during hospital stay and telephone follow-up and so on. Results: The proportion of CD200 expression in nnMCL patients was 8/14, which was higher than that in cMCL patients [14.6% (19/130)] (P=0.001). The proportion of CD23 expression in nnMCL patients was 8/14, which was higher than that in cMCL patients [13.5% (23/171)] (P<0.001). The proportion of CD5 expression in nnMCL patients was 10/14, which was lower than that in cMCL patients [97.4% (184/189)] (P=0.001). The proportion of CD38 expression in nnMCL patients was 4/14, which was lower than that in cMCL patients [69.6% (112/161)] (P=0.005). The expression proportion of sex-determining region of Y chromosome-related high-mobility-group box 11 (SOX11) in nnMCL patients was 1/5, which was lower than that in cMCL patients [77.9% (60/77)] (P=0.014). The proportion of immunoglobulin heavy chain variable region (IGHV) mutations in nnMCL patients was 11/11, which was higher than that in cMCL patients [26.0% (13/50)] (P<0.001). As of April 11, 2021, the follow-up time for nnMCL and cMCL patients was 31 (8-89) months and 48 (0-195) months, respectively. Among the 14 nnMCL patients, 6 patients were still under observation, and 8 patients were treated. The overall response rate (ORR) was 8/8, including 4 patients with complete remission and 4 patients with partial response. The median overall survival and median progression-free survival were not reached in nnMCL patients. In the cMCL group, 50.0% (112/224) patients achieved a complete response, 24.6% (55/224) patients achieved a partial response, and ORR was 74.6% (167/224). There was no statistically significant difference in ORR between the two groups (P=0.205). Conclusions: nnMCL patients have an indolent progression, with higher expression rates of CD23 and CD200 and lower expression rates of SOX11, CD5 and CD38. Most patients have IGHV mutations, with a relatively good prognosis, and”watch and wait”approach is an optional treatment.

ABSTRACT

BACKGROUND: The associations of adiposity with aggressive prostate cancer risk are unclear. Using two-sample Mendelian randomization, we assessed the association of metabolically unfavourable adiposity (UFA), favourable adiposity (FA) and for comparison body mass index (BMI), with prostate cancer, including aggressive prostate cancer.

METHODS: We examined the association of these genetically predicted adiposity-related traits with risk of prostate cancer overall, aggressive and early onset disease using outcome summary statistics from the PRACTICAL consortium (including 15,167 aggressive cases).

RESULTS: In inverse-variance weighted models, there was little evidence that genetically predicted one standard deviation higher UFA, FA and BMI were associated with aggressive prostate cancer [OR: 0.85 (95% CI:0.61-1.19), 0.80 (0.53-1.23) and 0.97 (0.88-1.08), respectively]; these associations were largely consistent in sensitivity analyses accounting for horizontal pleiotropy. There was no strong evidence that genetically determined UFA, FA or BMI were associated with overall prostate cancer or early age of onset prostate cancer.

CONCLUSIONS: We did not find differences in the associations of UFA and FA with prostate cancer risk, which suggest that adiposity is unlikely to influence prostate cancer via the metabolic factors assessed; however, these did not cover some aspects related to metabolic health that may link obesity with aggressive prostate cancer, which should be explored in future studies.

ABSTRACT

BACKGROUND: Escherichia coli and Klebsiella pneumoniae with a piperacillin-tazobactam-nonsusceptible/ceftriaxone-susceptible (TZP-NS/CRO-S) phenotype have been increasingly identified, with limited available literature evaluating treatment strategies.

METHODS: This was a retrospective study of noncritically ill adults hospitalized between 2013 and 2021 and treated at least 48 hours for TZP-NS/CRO-S E coli or K pneumoniae infections. The primary composite endpoint included escalation to intensive care unit, infection- or treatment-related readmission, mortality, and infection recurrence. Outcomes were compared between groups who received carbapenem (CG) versus carbapenem-sparing agents (CSG) as targeted gram-negative therapy.

RESULTS: Of 1062 patients screened, 200 were included (CG, n = 51; CSG, n = 149). Baseline characteristics, including Charlson Comorbidity Index (CCI; median [interquartile range], 6 [3-9] vs 6 [4-9]; P = .704), were similar between groups, except for more immunocompromised CG patients (29% vs 11%, P = .001). The most common infection sources were urinary (31% vs 57%, P = .002) and bloodstream (18% vs 17%, P = .887). Eighty-eight percent of the CG received meropenem, while 58% of the CSG received ceftriaxone as targeted therapy. There was no statistical difference in the primary endpoint between overall groups (27% vs 17%, P = .123), nor when stratified by infection source. More patients in the CSG switched to oral therapy (15 [29%] vs 100 [67%], P < .001). In multivariate analysis, CCI was an independent predictor of the primary outcome (odds ratio [OR], 1.199 [95% confidence interval, 1.074-1.340]; P = .001), while treatment with carbapenem-sparing therapy was not.

CONCLUSIONS: Our study did not find improved clinical outcomes with targeted carbapenem therapy for TZP-NS/CRO-S infections. Carbapenem-sparing agents may be considered to spare carbapenems in noncritically ill patients similar to those included in our cohort.

ABSTRACT

Ischemia/reperfusion injury (IRI) is a common cause of kidney damage, characterized by oxidative stress and inflammation. In this study, we investigated the potential protective effects of IAXO-102, a chemical compound, on experimentally induced IRI in male rats. The bilateral renal IRI model was used, with 24 adult male rats randomly divided into four groups (N=6): sham group (laparotomy without IRI induction), control group (laparotomy plus bilateral IRI for 30 minutes followed by 2 hours of reperfusion), vehicle group (same as control but pre-injected with the vehicle), and treatment group (similar to control but pre-injected with IAXO-102). We measured several biomarkers involved in IRI pathophysiology using enzyme-linked immunosorbent assay (ELISA), including High mobility group box1 (HMGB1), nuclear factor kappa b-p65 (NF-κB p65), interleukin beta-1 (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), 8-isoprostane, Bcl-2 associated X protein (BAX), heat shock protein 27 (HSP27), and Bcl-2. Statistical analysis was performed using one-way ANOVA and Tukey post hoc tests. Our results showed that IAXO-102 significantly improved kidney function, reduced histological alterations, and decreased the inflammatory response (IL-1, IL-6, and TNF) caused by IRI. IAXO-102 also decreased apoptosis by reducing pro-apoptotic Bax and increasing anti-apoptotic Bcl-2 without impacting HSP27. In conclusion, our findings suggest that IAXO-102 had a significant protective effect against IRI damage in the kidneys.

ABSTRACT

Classical Hodgkin lymphoma represents a paradigm of tumor cell-microenvironment interactions as the neoplastic Hodgkin Reed-Sternberg (HRS) cells typically constitute less than 1% of the total tumor volume. CTLA-4, a member of the CD28/B7 immunoglobulin superfamily, and CD28 and their ligands B7-1 and B7-2 are critically important for the initial activation of naive T cells. Strategies aimed at interfering with the crosstalk between tumoral Reed-Sternberg cells and their cellular partners have been taken into account in the development of new immunotherapies that target different cell components of the HL microenvironment. The study included 50 histopathological confirmed cases of Hodgkin lymphoma. IHC staining for CTLA-4 and B7-1 was performed on archival paraffin-embedded biopsy. SPSS version 17 was used for statistical analysis. CTLA-4 IHC expression in HRS cells was negative in all cases, while in immune cells, CTLA-4 expression was observed in 45 (90%) cases. CD80 expression was present in all cases, both in HRS and immune cells. There was a significant association between HRS cell percentage and IPS score (p-value=0.001). Mean survival duration was longer in <50% immune cells compared to >50% groups, with an overall mean survival of 67.633 months. Considering the CTLA4 expression in immune cells within the microenvironment and the availability of targeted drugs like Iplimumab, which act through CTLA4 blockade, it may be appropriate to use this as targeted therapy in HL cases, particularly in those with refractory disease who are unable to achieve cure prior to ASCT.

ABSTRACT

Despite Bangladesh being vulnerable to cyclones, there is a dearth of research on cyclone vulnerability assessment. Assessing a household’s vulnerability is considered a crucial step in avoiding the adverse effects of catastrophe risks. This research was conducted in the cyclone-prone district of Barguna, Bangladesh. This study’s purpose is to evaluate this region’s vulnerability. A questionnaire survey was conducted using a convenience sample technique. A door-to-door survey of 388 households in two Unions of Patharghata Upazila, Barguna district, was conducted. Forty-three indicators were selected to assess cyclone vulnerability. The results were quantified using an index-based methodology with a standardized scoring method. Where applicable, descriptive statistics have been obtained. In terms of vulnerability indicators, we also utilized the chi-square test to compare Kalmegha and Patharghata Union. When appropriate, the non-parametric Mann-Whitney U test was employed to evaluate the relationship between the Vulnerability Index Score (VIS) and the union. According to the results, the environmental vulnerability (0.53 ± 0.17) and the composite vulnerability index (0.50 ± 0.08) were significantly greater in Kalmegha Union than in Patharghata Union. They faced inequity in government assistance (71%) and humanitarian aid (45%) from national and international organizations. However, 83% of them underwent evacuation practices. 39% were satisfied with the WASH conditions at the cyclone shelter, whereas around half were dissatisfied with the status of the medical facilities. Most of them (96%) rely only on surface water for drinking. National and international organizations should have a comprehensive plan for disaster risk reduction that encompasses all individuals, regardless of race, geography, or ethnicity.

ABSTRACT

BACKGROUND: Following microsurgical vaso-epididymal anastomosis (VEA), anastomotic patency with sperm returning to the ejaculate is not always present and may even be delayed. The presence of motile spermatozoa is highly suggestive of future patency following surgery.

AIMS: We prospectively analyse the factors that could predict motile spermatozoa at the epididymis intraoperatively and predictors of patency in patients with obstructive azoospermia (OA) undergoing microsurgical VEA.

SETTINGS AND DESIGN: Department of Urology of a tertiary care centre in Northern India. It is a prospective observational study.

MATERIALS AND METHODS: Over a 2-year period (July 2019 to June 2021), 26 patients with idiopathic OA were enrolled in the study. Twenty patients underwent microsurgical VEA. Patients were divided into two groups based on the presence/absence of intraoperative motile spermatozoa.

STATISTICAL ANALYSIS USED: Analysis of preoperative and intraoperative factors was done using the Mann-Whitney U-test, Chi-squared test and Fischer exact test.

RESULTS: Out of 20 patients, 5 (group 2) had intraoperative motile spermatozoa in the epididymal fluid and 15 (group 1) had nonmotile spermatozoa. Low luteinising hormone (LH) levels (P = 0.01) and high testosterone levels (P = 0.05) were the predictive of presence of motile spermatozoa in epididymal fluid. Mean follow-up was 9 months (6-18 months). Predictors of higher patency were grade 2 epididymis (firm, turgid and tense) (P = 0.003), low LH levels (P = 0.03), low sertoli cell index (P = 0.006), high sperm-Sertoli index (P = 0.002) and better surgeon satisfaction (P = 0.01).

CONCLUSION: Low LH levels and high testosterone levels may be predictive of the presence of motile spermatozoa in epididymal fluid. Firm, turgid and tense epididymis, low Sertoli cell index, high sperm-Sertoli index and surgeon satisfaction suggest a greater chance of success after VEA for idiopathic azoospermia.

ABSTRACT

BACKGROUND: Vitrification of embryos following a single-controlled ovarian stimulation has been the strategy practised now in many in vitro fertilisation clinics to minimise the risk of early ovarian hyper stimulation syndrome, to reduce multiple pregnancy rates and to improve cumulative pregnancy rates. In recent years, advances in vitrification techniques and improved culture conditions have led to good post-thaw embryo survival rates, thereby increasing pregnancy rates of frozen embryo transfer (FET) cycles.

AIM: The aim of this study was to analyse the effect of post-thaw incubation time of frozen embryos on the clinical pregnancy rates (CPRs) of frozen embryo transfer (FET) cycles.

SETTINGS AND DESIGN: This was a retrospective, comparative study done at a teaching hospital in assisted reproductive treatment.

MATERIALS AND METHODS: Three hundred and ten FET cycles were analysed, of which 125 had day 2 freezing and 185 had day 3 freezing. Depending upon the day of thawing and day of transfer, FET cycles were divided into six groups: Group 1 (day 2 thawing and day 3 transfer), Group 2 (day 2 thawing and day 4 transfer), Group 3 (day 2 thawing and day 5 transfer), Group 4 (day 3 thawing and day 3 transfer), Group 5 (day 3 thawing and day 4 transfer) and Group 6 (day 3 thawing and day 5 transfer).

STATISTICAL ANALYSIS USED: Statistical analysis was performed using version 14 R software version 4.0.1 (2020-06-06) (R foundation for Statistical Computing, Vienna, Austria). A P < 0.05 is taken as significant.

RESULTS: The CPR of Group 4 was 42.4% which was more than that of the other groups but it did not reach statistical significance.

CONCLUSIONS: Short incubation time of 2-4 h is as effective as an extended incubation time in terms of CPRs of FET cycles.

ABSTRACT

Since the use of light and electronic devices is inevitable, the use of blue light filters (in various light sources, electronic devices or optical devices including intraocular lenses) has been shown to improve sleep quality, especially in later hours of the day and during night time. In this study, we examine the effect of the blue light on sleep and wakefulness rhythms and positive and negative emotions. This randomized clinical trial was conducted with 80 AJA University of Medical Sciences employees who use computers at least 2 h a day. All subjects were employees of the discharge unit of Imam Reza Hospital, which is located next to AJA University. The subjects were divided into two groups of 40 people, blue light filter software intervention and sham treatment. Pittsburgh Sleep Quality Index (PSQI), Positive and Negative Affect Schedule (PANAS), Visual Function Questionnaire (VFQ), Epworth Sleepiness Scale (ESS) and salivary melatonin and cortisol levels were assessed for both groups before and 3 months after the intervention. Data analysis was performed using IBM SPSS statistics for windows, version 21.0 (Armonk, NY: IBM Corporation). P value ≤ 0.05 was considered as statistically significant. The results showed that the Pittsburgh sleep scale after the intervention was significantly lower in the intervention group than in the control group. After the intervention, the VFQ was significantly lower in the intervention group than in the control group (P = 0.018). There was no significant difference in the Epworth Sleepiness Scale (ESS) between the two study groups after the intervention (P = 0.370). There was no significant difference in Positive and Negative Affect Schedule (PANAS) in the two study groups after the intervention (P = 0.140). After the intervention, cortisol levels were significantly higher in the intervention group than in the control group (P = 0.006). Also, the amount of cortisol increased significantly in the intervention group (P = 0.028). The amount of melatonin decreased significantly in the intervention group (P = 0.034). The sleep quality score after the intervention was significantly lower in the intervention group than in the control group. This indicates better sleep quality in the intervention group. The results also show that the level of visual fatigue in the intervention group decreased significantly. However, no significant change was detected regarding positive and negative emotions. After the intervention, cortisol levels were significantly higher in the intervention group than the control group. In addition, cortisol levels increased significantly and melatonin levels decreased significantly in the intervention group during the course of study.
