Background:
Consumption and abuse of alcohol remains a significant cause of concern worldwide. Furthermore, there is evidence of the association between chronic alcohol use and reduced life expectancy.
Objectives:
To study the effects of Garcinia binucao extract (GBE) supplementation on lifespan of Drosophila
melanogaster, in the presence or absence of chronic alcohol exposure.
Methods:
D. melanogaster was mass cultured and given GBE supplementation in high (1 mg/mL) and low (200 µg/mL) sublethal doses. D. melanogaster flies were divided into groups - with and without chronic alcohol exposure, and their respective lifespans were monitored.
Results:
In D. melanogaster without alcohol exposure, mean lifespan was highest in the control flies (38.15 days), followed by high-dose GBE (34.42 days), low-dose GBE (33.24 days), and DMSO (22.29 days). In D. melanogaster chronically exposed to alcohol, the longest mean lifespan was observed in flies treated with high-dose GBE (33.80 days), followed by low-dose GBE (33.63 days), the DMSO group (30.30), and the control group (29.65 days), but the differences were not statistically significant. Comparing groups with and without chronic alcohol exposure, the mean lifespan of the control group chronically exposed to alcohol significantly decreased by 9.51 days (p < 0.05). In GBE treatment groups, mean lifespan significantly decreased by 0.82 days in high-dose set-up (p < 0.05), and significantly increased by 0.39 days in the low-dose set-up (p < 0.05) upon chronic alcohol exposure.
Conclusion
Garcinia binucao extract supplementation ameliorated the observed reduction in lifespan of Drosophila melanogaster chronically exposed to alcohol.

Pediatric intracerebral hemorrhage is a rare condition among children. We discuss the case of a 7-year-old Filipino male with generalized tonic seizures and diagnosed to have both SARS-CoV-2 infection and hypertension secondary to renal arterial stenosis. The occurrence of intracerebral hemorrhage in children, though commonly caused by arteriovenous malformations, may be secondary to an acute hypertensive episode. In this case, the presence of COVID-19 in the patient may have been contributory to the development of spontaneous intracerebral hemorrhage due to its direct endothelial effects, as well as its dysregulatory action on the renin-angiotensin-aldosterone system.

Background:
The PLASMIC score is a convenient tool for predicting ADAMTS13 activity of <10%.Lactate dehydrogenase (LDH) is widely used as a marker of haemolysis in thrombotic thrombocytopenic purpura (TTP) monitoring, and could be used as a replacement marker for lysis. We aimed to validate the PLASMIC score in a multi-centre Asia Pacific region, and to explore whether LDH could be used as a replacement marker for lysis.
Methods:
Records of patients with thrombotic microangiopathy (TMA) were reviewed. Patients’ ADAMTS13 activity levels were obtained, along with clinical/laboratory findings relevant to the PLASMIC score. Both PLASMIC scores and PLASMIC-LDH scores, in which LDH replaced traditional lysis markers, were calculated. We generated a receiver operator characteristics (ROC) curve and compared the area under the curve values (AUC) to determine the predictive ability of each score.
Results:
46 patients fulfilled the inclusion criteria, of which 34 had ADAMTS13 activity levels of <10%. When the patients were divided into intermediate-to-high risk (scores 5‒7) and low risk (scores 0‒4), the PLASMIC score showed a sensitivity of 97.1% and specificity of 58.3%, with a positive predictive value (PPV) of 86.8% and negative predictive value (NPV) of 87.5%. The PLASMIC-LDH score had a sensitivity of 97.1% and specificity of 33.3%, with a PPV of 80.5% and NPV of 80.0%.
Conclusion
Our study validated the utility of the PLASMIC score, and demonstrated PLASMIC-LDH as a reasonable alternative in the absence of traditional lysis markers, to help identify high-risk patients for treatment via plasma exchange.

Background:
Due to the high prevalence and incidence of leprosy in the Philippines, there is a continuing need to detect and document
the occurrence of dapsone-induced hemolytic anemia.
Objective:
The aim of this study is to determine the incidence of dapsone-induced hemolytic anemia in non-glucose-6-phosphate dehydrogenase deficient leprosy patients receiving multidrug therapy (MDT) in Southern Philippines Medical Center.
Methodology:
This is a retrospective study through chart review of leprosy patients treated with MDT regimen at Southern Philippines
Medical Center from January 2016 to December 2018. The demographic profile, clinical characteristics, hemoglobin and hematocrit concentrations before and after initiation of MDT, the presence of symptoms of anemia, and the occurrence of dapsone-induced hemolytic anemia
in leprosy patients were collected. The main outcome measure for this study was the incidence rate of dapsone- induced hemolytic anemia.
Statistical-based analysis were used for continuous and categorical data which were summarized using means and standard deviations,
and frequencies and percentages, respectively.
Results:
There was a decrease in the mean hemoglobin and hematocrit levels noted in the majority of patients after initiation of MDT from
baseline 143.46 g/dl and 0.44, respectively, to 94 g/dl and 0.28 on the third month of MDT. The incidence rate of dapsone-induced hemolytic
anemia during the 3-year period was 20 cases per 100.
Conclusion
The relatively high incidence rate of dapsone-induced hemolytic anemia highlights the importance of frequent monitoring
of hemoglobin and hematocrit concentrations in leprosy patients being treated with multidrug therapy.

Purpose:
To determine psychometric properties of the Caring Behaviors Inventory-24 (CBI-24) among Korean clinical nurses.
Methods:
A methodological design was used. Data were collected from 408 clinical nurses. Construct validity analysis was performed, including factorial, convergent, and discriminant validity. Internal consistency was tested by Cronbach’s ⍺ coefficients, inter-item correlation, and corrected item-total correlation.
Results:
Exploratory factor analysis produced three factors: ‘empathy and supporting’, ‘knowledge and skills’, and ‘providing comfort’. In confirmatory factor analysis results, model fit indices were acceptable (x2/df=3.50, RMR=.05, RMSEA=.08, CFI=.90). The values obtained for the AVE ranged from .53 to .68, and for the CR ranged from .53 to .68. Convergent validity coefficients were noticeably greater in magnitude than discriminant validity coefficients: .53 (AVE1 value) and .68 (AVE2 value)≥.45 (r122 value) and .68 (AVE2 value) and .63 (AVE3 value)≥.61 (r232 value). Internal consistency (Cronbach’s ⍺) of CBI-K was .95.
Conclusion
The CBI-K was shown to have acceptable construct validity and good internal consistency. Study findings imply that CBI-K could be a useful instrument for clinical administrators and nursing researchers to assess caring behaviors among Korean clinical nurses. Utilization of CBI-K might contribute to the building of empirical knowledge and the understanding of caring behaviors from nurses’ perspectives.

Silymarin is the standardized extract from Silybum marianum which consists mainly of flavonoids and polyphenols. It is highly regarded for its hepatoprotective ability. Silybin B is a flavonolignan and one of the active components of silymarin. The content of silybin B in various parts of S. marianum was analyzed by HPLC-UV. Results show that the extract of seeds contain the highest amount of silybin B (7.434 mg/g DW). The petioles of S. marianum showed a low content of silybin B. This study revealed that seeds of S. marianum contain high amount of silybin B and could be a good source of the compound.
