ABSTRACT

Objective: We aimed to investigate the effect of play therapy combined with the standard psychotropic medication treatment, compared to only standard psychotropic medication treatment in ADHD children as measured by the test of variables of attention (TOVA).Methods: This is a case-control study conducted at Soerojo Hospital, Magelang, Indonesia. Children (N = 66) were purposively recruited. The children were divided into two groups based on the intervention received: the experimental group (play therapy and standard psychotropic medication) and control group (standard psychotropic medication only). Methylphenidate was used as the standard psychotropic therapy. The TOVA was performed before and after intervention. The pre-intervention and post-intervention mean difference (MD) in the Attention Comparison Score (ACS) and Comparison to the Normative Sample (CNS) for each group was compared and statistically analysed using t-tests and Wilcoxon tests.Results: There was a significant difference between the ACS score of the experimental group’s MD and the control group’s MD (p < 0.05). For most TOVA parameters on CNS scores, the experimental group had a significantly higher MD than the control group.Conclusion: Play therapy coupled with psychotropic medication reduced ADHD symptoms, including inattention and impulsivity, as objectively measured by the TOVA.

ABSTRACT

BACKGROUND: The impact of incidental prostate cancer (IPC) on oncological outcomes after radical cystoprostatectomy (RCP) specimens from patients with bladder cancer (BC) remains controversial. This relationship has not been well elucidated in Asian countries, where the incidence of prostate cancer has recently shown dramatic increases.

OBJECTIVES: This study retrospectively compared pathological features and oncological outcomes between BC patients with and without IPC in the RCP specimens.

METHODS: This study included 142 men who underwent RCP for BC. Men who were previously diagnosed with prostate cancer were excluded. Each prostate gland and seminal vesicle was processed as whole mounts and 4-mm close-step sectioning was performed. A single genitourinary pathologist diagnosed IPC. The pathological features and oncological outcomes such as overall survival (OS), bladder cancer-specific survival (BCSS), and progression-free survival (PFS) were compared between patients with IPC (IPC+group, n = 45) and without IPC (IPC- group, n = 97). P values less than 0.05 considered to indicate statistical significance for patients’ characteristics. Because of multi-primary endpoint, P values less than 0.0167 was considered statistical significance for oncological outcomes.

RESULTS: We detected IPC in 45 RCP specimens (31.6%). Patients in the IPC- group were significantly younger at surgery than those in the IPC+group (P < 0.001). The pathological features of the RCP specimens did not differ significantly. In multivariable analyses, presence of IPC was significantly associated with worse OS (P = 0.005), but not with either BCSS or PFS (P = 0.038 and 0.326, respectively). In Kaplan-Meier analyses, OS tended to be longer in the IPC- group than that in the IPC+group (NR vs 65 months, P = 0.0017).

CONCLUSIONS: Our results suggested significantly better OS in patients without IPC than that in those with IPC.

ABSTRACT

BACKGROUND: Atezolizumab is an immune checkpoint inhibitor (ICI) and a frontline treatment of patients with cisplatin-ineligible advanced urothelial carcinoma (UC). There is limited evidence on the prognostic value of patient reported outcomes (PROs) in advanced UC treatment, particularly in the context of ICI therapy.

OBJECTIVE: To investigate the prognostic association of PROs with survival in patients with advanced UC treated with atezolizumab.

METHODS: This study used data from 467 patients with advanced UC initiating atezolizumab in the IMvigor211 trial. Pre-treatment PROs association with overall survival (OS) and progression free survival (PFS) was assessed using Cox proportional hazard analysis. PROs were recorded via the European Organisation for Research and Treatment of Cancer QLQ-C30. Discrimination performance was assessed via the C-statistic (c).

RESULTS: Patient reported physical function, pain, appetite loss, global health, fatigue, role function, constipation, nausea and vomiting, dyspnoea, and insomnia were significantly associated with OS and PFS on univariable and adjusted analysis (P < 0.05). Physical function (c = 0.63), pain (c = 0.63), appetite loss (c = 0.62), global health status (c = 0.62), and fatigue (c = 0.62), were the most prognostic factors of OS. The OS discrimination performance of physical function (c = 0.61) was superior to ECOG PS (c = 0.58). Of patients assessed by investigators as having no performance restrictions (ECOG PS of 0), 38 (18%) and 91 (42%) self-reported low and intermediate physical function scores, respectively.

CONCLUSION: Pre-treatment PROs were identified as independent prognostic factors of OS and PFS. Patient-reported physical function was more prognostic of OS than ECOG PS. This highlights a potential for PROs to enable improved patient stratification in ICI trials.

ABSTRACT

AIM: The study was aimed to find out the efficacy of a stool color card (SCC) in differentiating biliary atresia (BA) from non-BA in resource-limited countries.

BACKGROUND: stool color screening system was introduced in 2004 which lead to marked improvement in sensitivity of detecting BA.

METHODS: This cross-sectional observational study was conducted from January, 2019 through July, 2022 on purposively sampled infants who developed jaundice before three months of age, had direct bilirubin of > 20 % of total with pale stool and dark urine.

RESULTS: 144 cases (male, 96) were included in the study and their mean age at admission was 87.3±37.2 days and mean age at onset of jaundice was 6.1±7.7 days. BA was confirmed in 106 (73.6%) cases and 38 (26.4%) children were in non-BA group. Frequency of persistent pale stool between BA and non- BA were 88 vs 8 (83.0 % Vs 21.0 %) which was highly significant (p=0.000). Mean difference of total and direct serum bilirubin, median alanine transferase and alkaline phosphatase were not statistically significant between two groups. Median of serum gamma glutamyl transpeptidase (GGT) in BA was 570 U/L and in non-BA it was 138.0 U/L which was statistically significant (p=0.000). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of SCC were 83%, 78.9%, 91.7%, 62.5% and 81.9% respectively.

CONCLUSION: SCC has good sensitivity to diagnose BA but failed to prove better specificity to rely simply on it. SCC may be used as early screening tool for prompt referral to appropriate medical care centers for final evaluation of BA.

ABSTRACT

AIM: Until now, there has been disagreement regarding the prevalence, causes, predisposing factors, and outcome of ACLF (Acute-on-chronic liver failure). As a result, we have undertaken this research study.

BACKGROUND: ACLF is a complex syndrome with a poor prognosis.

METHODS: In this cross-sectional study, we evaluated the prevalence, causes, predisposing factors, and outcomes of adult cirrhotic patients with ACLF and acute decompensation (AD). ACLF was defined based on the criteria established by APASL (Asian Pacific Association for the Study of the Liver). The severity of organ failure was assessed using both EASL-CLIF (European Association for the Study of the Liver- Chronic Liver Failure) and NACSELD (North American Consortium for the Study of End-Stage Liver Disease) scores. To investigate the impact of different independent variables on mortality, survival analysis methods were used.

RESULTS: A total of 156 patients’ data were analyzed in this study. The mean age of patients with ACLF (56.62±16.19 years) was significantly lower compared to the AD group (62.30±14.28 years). Nonalcoholic steatohepatitis and infection were the most common causes and predisposing factors in both AD and ACLF groups, respectively, but the difference between the two groups was not statistically significant. The most common organ failures observed were hepatic encephalopathy and respiratory failure. The probability of death at any given time for was significantly higher in ACLF patients than in the AD group (log rank test; P<0.001). The results of Cox regression analysis revealed that low blood pressure (HR 0.97; 95% CI 0.96-0.99; P<0.001) and decreased blood pH (HR 0.53; 95% CI 0.28-0.99; P=0.04) were significant risk factors associated with increased mortality.

CONCLUSION: ACLF patients had a lower average age and higher mortality rates compared to AD. Nonalcoholic steatohepatitis was found to be the most common underlying disease in ACLF patients, while infections were identified as the predominant predisposing factor. All cases of mortality in the ACLF group were categorized as grade 3 and 4 based on the EASL-CLIF severity score. Hemodynamic instability and metabolic acidosis emerged as the most significant risk factors associated with increased mortality.

ABSTRACT

AIM: This study aimed to determine the distribution of enteric parasitic infections and related risk factors among rural communities of Guilan province, Northern Iran, and to compare the results with the situation in the past.

BACKGROUND: Intestinal parasitic infections are still considered as a major public health concern, particularly in human communities with poor economy and sanitation.

METHODS: This cross-sectional study was performed in rural areas of Masal and Shanderman district from February to December 2020. A total of 917 stool samples were collected and examined for presence of intestinal helminthes and protozoa using direct, formalin-ether and Kato-Katz techniques.

RESULTS: A total of 156 (17%) out of 917 examined individuals were infected with intestinal parasites. The overall prevalence of protozoa, helminths and mixed infections were 11.8% (108/917), 4.5% (41/917) and 0.8% (7/917), respectively. Blastocystis was the most prevalent intestinal protozoa (9.6%) followed by Giardia lamblia (1.9%), Endolimax nana (1.1%), E. coli (0.8%) and Entamoeba hartmani (0.1%). The highest prevalence of intestinal helminths belonged to Trichostongylus spp. (3.5%) and Strongyloides stercoralis (1.3%). Statistical analysis showed significant association between giardiasis and sex (P<0.03). On the other hand, prevalence of enteric helminths was influenced by close contact with livestock, keeping herbivorous animals at home, job, education, and consumption of uncooked vegetables (P<0.05).

CONCLUSION: The findings indicate a decreasing trend in the prevalence of intestinal parasitic infections in Guilan province in comparison to the past few decades. Hookworm infections, which was very prevalent in the area, are now rare, while trichostrongylosis showed a high prevalence in rural residents of the study area.

ABSTRACT

AIM: The purpose of this investigation was to examine the potential association between non-alcoholic fatty liver disease (NAFLD) and adverse maternal and perinatal outcomes during pregnancy.

BACKGROUND: Gaining insights into the effect of NAFLD on pregnancy outcomes is essential to ensure the health and well-being of mothers and infants.

METHODS: This prospective cohort study was conducted at Imam Khomeini and Razi hospitals of Ahvaz City in 2022. Totally, 180 pregnant women in the NAFLD group to 180 in the control group. In this study, a researcher-made checklist was used to collect the background information, medical history, and lab data during their initial visit using. Follow-up continued until one week after delivery, with pregnancy outcomes assessed. Statistical analysis used student’s t-test and the Chi-Square test for group comparisons.

RESULTS: Significant differences were observed between the NAFLD, and control groups in terms of age (P=0.003), BMI (P=0.016), ALT and AST measures (P<0.001), and hypertensive complications (P=0.044). The NAFLD group had higher rates of gestational diabetes (P<0.001) and gestational hypertension (P=0.003). However, no significant differences were found in gestational age at delivery, early postpartum hemorrhage rates, birth weight, and neonatal Apgar scores (P>0.05).

CONCLUSION: The pregnant women with NAFLD may be at risk for various complications during pregnancy, including a higher prevalence of gestational diabetes, elevated liver enzymes, and higher blood pressure compared to healthy pregnant women. However, the research failed to identify any statistically significant disparities between infants born to mothers with NAFLD and those delivered to healthy mothers in relation to birth weight, Apgar scores, or neonatal mortality.

ABSTRACT

Densely packed, motile bacteria can adopt collective states not seen in conventional, passive materials. These states remain in many ways mysterious, and their physical characterization can aid our understanding of natural bacterial colonies and biofilms as well as materials in general. Here, we overcome challenges associated with generating uniformly growing, large, quasi-two-dimensional bacterial assemblies by a membrane-based microfluidic device and report the emergence of glassy states in two-dimensional suspension of Escherichia coli. As the number density increases by cell growth, populations of motile bacteria transition to a glassy state, where cells are packed and unable to move. This takes place in two steps, the first one suppressing only the orientational modes and the second one vitrifying the motion completely. Characterizing each phase through statistical analyses and investigations of individual motion of bacteria, we find not only characteristic features of glass such as rapid slowdown, dynamic heterogeneity, and cage effects, but also a few properties distinguished from those of thermal glass. These distinctive properties include the spontaneous formation of micro-domains of aligned cells with collective motion, the appearance of an unusual signal in the dynamic susceptibility, and the dynamic slowdown with a density dependence generally forbidden for thermal systems. Our results are expected to capture general characteristics of such active rod glass, which may serve as a physical mechanism underlying dense bacterial aggregates.

ABSTRACT

Pancreatic carcinoma is a relatively common malignant tumor with increasing incidence and mortality. The tumor is usually diagnosed at an advanced stage and generally has a poor prognosis, with only 5% of patients surviving 5 years from the time of diagnosis. The stage of the disease at the time of diagnosis is a crucial factor for the prognosis; 25% of patients with localized tumors survive 3 years from diagnosis, compared to only 1% of those with generalized tumors. Radical surgical removal of the tumor (partial or total pancreatectomy) is a key factor in improving survival. Therefore, the topic is highly relevant to surgeons. Statistics on pancreatic carcinoma mainly focus on ductal adenocarcinoma, which is the most common and least favorable malignant tumor of the pancreas. This review focuses on ductal adenocarcinoma, its variants, and precancerous lesions. The article summarizes information from the latest WHO classification of 2019, which was released 11 years after the previous edition. Compared to the previous version, this new WHO classification introduced rather minor changes in the field of ductal adenocarcinoma. The delineation of rare variants of ductal adenocarcinoma is justified based on genetic and morphological similarities and clinical relevance, as individual subtypes significantly differ in prognosis. The article also includes a description of macroscopic and microscopic precursors of ductal adenocarcinoma and their definitions. Genetic and immunohistochemical differential diagnostic aspects are briefly discussed, as these are more relevant to pathologists than to surgeons.

ABSTRACT

BACKGROUND AND PURPOSE: Prediction of aneurysm instability is crucial to guide treatment decisions and to select appropriate patients with unruptured intracranial aneurysms (IAs) for preventive treatment. High resolution four-dimensional magnetic resonance (4D MRI) flow imaging and 3D quantification of aneurysm morphology could offer insights and new imaging markers for aneurysm instability. In this cross-sectional study, we aim to identify 4D MRI flow imaging markers for aneurysm instability by relating hemodynamics in the aneurysm sac to 3D morphological proxy parameters for aneurysm instability.

MATERIALS AND METHODS: In 35 patients with 37 unruptured IAs, a 3T MRA and a 7T 4D flow MRI scan was performed. Five hemodynamic parameters -peak-systolic (WSS_MAX) and time-averaged wall shear stress (WSS_MEAN), oscillatory shear index (OSI), mean velocity, and velocity pulsatility index (vPI)-were correlated to six 3D morphology proxy parameters of aneurysm instability -major axis length, volume, surface area (all three size parameters), flatness, shape index, and curvedness -by Pearson’s correlation with 95% confidence intervals (CI). Scatterplots of hemodynamic parameters that correlated with IA size (major axis length) were created.

RESULTS: WSS_MAX and WSS_MEAN correlated negatively with all three size parameters (strongest for WSS_MEAN with volume (r = -0.70, 95% CI -0.83 to -0.49)) and OSI positively (strongest with major axis length (r = 0.87, 95% CI 0.76 to 0.93)). WSS_MAX and WSS_MEAN correlated positively with shape index (r = 0.61, 95% CI 0.36 to 0.78 and r = 0.49, 95% CI 0.20 to 0.70, respectively) and OSI negatively (r = 0.82, 95% CI -0.9 to -0.68). WSS_MEAN and mean velocity correlated negatively with flatness (r = -0.35, 95% CI -0.61 to -0.029 and r = 0.33, 95% CI -0.59 to 0.007, respectively) and OSI positively (r = 0.54, 95% CI 0.26 to 0.74). vPI did not show any statistically significant correlation.

CONCLUSIONS: Out of the five included hemodynamic parameters, WSS_MAX, WSS_MEAN, and OSI showed the strongest correlation with morphological 3D proxy parameters of aneurysm instability. Future studies should assess these promising new imaging marker parameters for predicting aneurysm instability in longitudinal cohorts of IA patients.
