It has the potential to hamper their sleep quality as well act as a precipitating factor for depression. This study thus assessed the magnitude of smartphone addiction, excessive daytime sleepiness and depression among undergraduate medical students in Kolkata and elicited its determinants. Materials and Methods: This cross-sectional study was conducted among 204 undergraduate medical students in a selected medical college of Kolkata from March to June 2023. Smartphone addiction, daytime sleepiness and depression was assessed using the SAS-SV, EPSS and PHQ-9 questionnaires. Logistic regression analysis was undertaken to determine the associated factors of smartphone addiction, while Spearman’s correlation coefficient was estimated to find the relationship of smartphone addiction with depression and daytime sleepiness. Results: Approximately 29.4% participants were addicted to smartphone, 45.5% were suffering from excessive daytime sleepiness. The depression scores on the PHQ-9 scale showed a mean value of 8.15 (±4.72). Factors significantly associated with smartphone addiction were increasing age (AOR=1.23, 95%CI=1.12-2.21), male gender (AOR=2.12, 95% CI=1.36-3.45) and duration of smart phone usage >6 hours per day (AOR=1.92, 95%CI=1.23-2.45). Smartphone addiction showed positive correlation with both daytime sleepiness (ρ =0.5, p-value<0.05) and depression (ρ=0.23, p-value=0.001) Conclusion: Utmost care should be taken for promoting good mental health and wellbeing among medical students. Motivation and counselling sessions along with peer support groups can help in combating this addictive behaviour and depressive symptoms.","PeriodicalId":37270,"journal":{"name":"Siriraj Medical Journal","volume":"18 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135565236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The secondary objectives include the analgesic effect and moisturization of these two products. Materials and Methods: Data was collected between 2019 and 2021. Patients aged 18 years and above, with superficial second-degree burns including at least 20% of TBSA, and admitted to the Burn Unit within 24 hours of injury were included. They were randomly assigned to two groups: Andrographis paniculata with Perilla oil liquid soap group (AP group) and 4% Chlorhexidine group (control group). The measurements included percentage of epithelialization, pain score during wound cleansing, itching score after wound cleansing, and dry skin specified symptoms. All patients received standard care for burn wound treatment. Results:  A total enrollment was 23 patients in this study (12 in the AP group and 11 in the control group). The median age was 38.5 years. There were no statistically significant differences in age, %TBSA, and initial wound size between both groups (p > 0.05). Although the healing time was similar in both groups, (18.5 vs. 20.1, p=0.347), the AP group had a significantly lower pain score than the control group (4.7 vs. 5.4, p=0.020). Moreover, the AP group demonstrated significant improvements in itching score and SRRC score at 14 days compared to the control group (5.1 vs. 6.0, p 0.039 and 1.08 vs. 1.55, p 0.020, respectively). There were no adverse effects during this study.  Conclusion: Patients treated with Andrographis paniculata with Perilla oil liquid soap experienced less pain and better moisturization compared to those treated with the standard 4% chlorhexidine solution, while achieving a comparable healing rate.

Materials and Methods: Medical records were retrieved from 61 patients who were diagnosed with HCC from 2008-2018. Clinical and histomorphological variables that were hypothesized to be associated with histological grade and microvascular invasion were analyzed statistically using the Chi-square test or the Fisher’s exact test as alternatives. Multivariate analysis was performed with logistic regression model. Results: The majority of the patients had well to moderately-differentiated HCC (67.2%) with some of them presenting microvascular invasion (57.4%). Alpha-fetoprotein level (AFP) ≥100 ng/ml (p=0.036), tumor size >7cm (p=0.031) and mitotic index ≥5 per 10 high power field (p=0.009) were significantly correlated with poorly-differentiated HCC. Mitotic Index ≥5 per 10 high power field was an independent factor for poorly differentiated HCC. Meanwhile BCLC stage B and mitotic index were also an independent factor for the presence of microvascular invasion. Conclusion: Larger tumor size and higher mitotic index was significantly correlated and independent factors for poorly differentiated HCC and microvascular invasion. In biopsy specimens for which the microvascular invasion is difficult to assess, histological grade, tumor size and mitotic index may be beneficial to depict the prognosis of patients with HCC.","PeriodicalId":37270,"journal":{"name":"Siriraj Medical Journal","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139305089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: The medical records of 248 myopia-diagnosed patients were reviewed. All patients were received low-dose atropine eye drops and had at least one follow-up visit within 1 year after the treatment initiation. Spherical equivalent (SE) measurements were collected at pre- and post-treatment visits, as well as any reported side effects. Comparing the SE changes observed between the pre- and post-treatment periods, as well as between the two different concentrations of atropine was analyzed. Results: A total of 495 eyes were analyzed, with 461 eyes receiving 0.01% atropine eye drops and 32 eyes being administered 0.05%. The demographic data between two groups showed no significant difference. The comparison of SE change one year prior to and one year after treatment in the 0.01% and 0.05% group yielded a p-value of less than 0.001 and 0.003, respectively, (SE change are -0.38 (-0.75-0.00) and -0.25 (-0.72-(-0.25)) in the 0.01% and 0.05% group, respectively). However, the between-group comparison of SE change at 6 months and 1 year showed no significant difference. Regarding side effects, one-third of the eyes in the 0.05% group (37.5%) experienced adverse effects while only eight eyes (1.7%) in the 0.01% group reported side effects. Conclusion: This research contributes support to the effectiveness of employing low-dose atropine for the treatment of myopia in Thai children. Nonetheless, it is worth noting that the use of 0.05% atropine was associated with a higher incidence of side effects.","PeriodicalId":37270,"journal":{"name":"Siriraj Medical Journal","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139293811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to identify independent factors affecting short-term HRV parameters and BRS, as well as determine appropriate reference ranges, which are lacking in Asian populations. Materials and Methods: A total of 117 healthy Thai participants (aged 20-72 years; final n=117) were recruited based on strict criteria, including normal medical history, physical examination (ascertained by a physician), and normal blood profile. Spontaneous 5-minute HRV parameters (time and frequency domains) and spontaneous cross-correlation BRS were measured. Results: Age and resting heart rate (HR) are independently and inversely correlated with BRS and all HRV parameters, except LFnu (normalized low-frequency component) and LF/HF ratio (ratio of low- to high-frequency component). Sex differences were observed only in LF, which was higher in men. However, multiple regression analysis showed that sex did not significantly contribute as an independent variable to either HRV or BRS. Remarkably, BRS exhibited moderate to strong correlations with all HRV values, indicating its prominent role in influencing HRV and surpassing the impact of age. Conclusion: Age and resting HR were identified as independent factors influencing 5-minute HRV and BRS. Our findings suggest that decreased baroreflex function associated with aging may contribute to reduced HRV among the elderly. Furthermore, we established reference ranges for each 5-minute HRV parameter and BRS, categorized by age group (20-39, 40-59, and ≥60 years old). These reference values offer valuable clinical insights, particularly for Asian populations where such normative ranges were previously unavailable.","PeriodicalId":37270,"journal":{"name":"Siriraj Medical Journal","volume":"08 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135457666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is recommended to replace the 68Ge/68Ga generator after 250 elutions or 12 months of shelf-life whichever endpoint is reached first. However, a 68Ge/68Ga generator that has gone past its recommended lifespan can still be further used as a 68Ga source for 68Ga-labeled radiopharmaceuticals for use in animal experiments. To ensure the quality of 68Ga eluates, we aimed to evaluate the efficacy and safety of the ITM (Isotope Technologies München) 68Ge/68Ga generator in our institute after its recommended shelf-life. Materials and Methods: A 21-month-old ITM 68Ge/68Ga generator was eluted using 4.0 ml of 0.05 M HCl. The 68Ga elution yields were calculated, and 68Ge breakthrough was measured at least 48 h after elution in an aliquot amount using a multichannel analyzer (MCA) with a high-purity germanium probe. Metal impurities in the 68Ga eluates were analyzed by ICP-MS. Results: The elution yield of 68Ga was 35.2 ± 8.1%; n = 5 (decay corrected). 68Ge breakthrough from the ITM 68Ge/68Ga generator was below the detectable level. The average amounts of the metallic ions 57Fe, 66Zn, 203Pb, 60Ni, and 63Cu were 18.60, 9.86, 2.42, 0.52, and 0.47 µg/GBq, respectively. Conclusion: The ITM 68Ge/68Ga generator demonstrated consistent and reliable 68Ga elution profiles with an absence of either 68Ge breakthrough or other metal contaminants in the eluent samples as verified by the manufacturer. The use of the ITM 68Ge/68Ga generator could be extended past its recommended shelf-life to prepare 68Ga radiopharmaceuticals that are considered safe and suitable for use in animal experimentation and other applications.","PeriodicalId":37270,"journal":{"name":"Siriraj Medical Journal","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135458925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These attributes are expected to enhance drug compliance, particularly in stable patients. The previous studies demonstrated that the efficacy of LAI-aripiprazole and LAI-paliperidone palmitate is controversial. Nevertheless, the costs of treatments and adverse events of both LAI-aripiprazole and LAI-paliperidone palmitate are unlikeness. As there had been no previous cost-effectiveness studies comparing the use of LAI-aripiprazole and LAI-paliperidone palmitate in Thailand, this study was carried out to investigate the matter. Materials and Methods: This study analysed the cost-effectiveness of LAI-aripiprazole compared with LAI-paliperidone palmitate in the treatment of stable schizophrenia, by using the Markov model from a societal perspective. Results: The total cost of treatment with LAI-aripiprazole and LAI-paliperidone palmitate was 1,334,919.05 baht and 1,329,818.79 baht, respectively, while the quality-adjusted life years (QALYs) were both 16.35 years. Life-year of the treatment with LAI-aripiprazole and LAI-paliperidone was 24.27 years and 24.25 years, respectively. The cost-effectiveness ratios (CER) of the treatment with LAI-aripiprazole and LAI-paliperidone palmitate were 81,652.85 baht/QALY gained and 81,330.94 baht/QALY gained, respectively. Conclusion: In Thailand, the treatment of stable schizophrenia with LAI-aripiprazole was shown to provide similar benefits to LAI-paliperidone palmitate in terms of QALYs, despite being more costly. Comparatively, LAI-aripiprazole exhibited better clinical efficacy and led to a longer average life expectancy than LAI-paliperidone. Treatment with LAI-aripiprazole may be dominant strategy, especially with a 2% reduction in drug cost. The results could contribute to appropriate decision-making by policymakers.","PeriodicalId":37270,"journal":{"name":"Siriraj Medical Journal","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135509161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
