Objective: To investigate and characterize the chemical composition of the different crude extracts from the leaves of Broussonetia luzonica (Blanco) (Moraceae) (B. luzonica), an endemic plant in the Philippines.
Methods: The air dried leaves were powdered and subjected to selective sequential extraction using solvents of increasing polarity through percolation, namely, n-hexane, ethyl acetate and methanol to obtain three different extracts. Then, each of the extracts was further subjected to gas chromatography–mass spectrometry.
Results: Qualitative determination of the different biologically active compounds from crude extracts of B. luzonica using gas chromatography–mass spectrometry revealed different types of high and low molecular weight chemical entities with varying quantities present in each of the extracts. These chemical compounds are considered biologically and pharmacologically important. Furthermore, the three different extracts possess unique physicochemical characteristics which may be attributed to the compounds naturally present in significant quantities in the leaves of B. luzonica.
Conclusions: The three extracts possess major bioactive compounds that were identified and characterized spectroscopically. Thus, identification of different biologically active compounds in the extracts of B. luzonica leaves warrants further biological and phar-macological studies.

BACKGROUND: Permethrin shampoo is currently the first-line treatment for pediculosis capitis. However, its widespread use has resulted in the development of resistance.
OBJECTIVE: To compare aromatic oil shampoo and 1% permethrin shampoo in terms of efficacy and safety
METHOD: One hundred fifty-hour patients with active infestation were treated in this randomized, assessor-blind, controlled trial using aromatic oil or permethrin shampoo, applied once weekly for three weeks. Evaluations were conducted at baseline and a week after shampoo application. Complete cure was defined as the absence of live louse on day 21.
RESULTS: There were no significant differences between the two groups in terms of complete cure, changes in patient's quality of life and pruritus at day 21. Neither group reported any diverse effects.
CONCLUSION: The efficacy and safety of the aromatic oil shampoo was comparable to that of 1%permethrin shampoo in treating pediculosis capitis.

Purpose:
Type 1 diabetes (T1D) is the most common type of diabetes in children, but the frequency of type 2 diabetes (T2D) is increasing rapidly. Classification of diabetes is based on a constellation of features that vary by type. We aimed to compare demographic, clinical, and laboratory characteristics at diagnosis of pediatric T1D and T2D.
Methods:
We studied children who visited a large academic hospital in Houston, Texas (USA) with a new diagnosis of T2D (n=753) or T1D (n=758). We compared age, sex, race/ethnicity, presence of obesity, glucose, hemoglobin A1c, islet autoantibody positivity, C-peptide, and presence of diabetic ketoacidosis (DKA) at diabetes diagnosis.
Results:
At diagnosis, children with T2D, compared with those with T1D, were older (13.6 years vs. 9.7 years), more likely female (63.2% vs. 47.8%), of racial/ethnic minority (91.1% vs. 42.3%), and obese (90.9% vs. 19.4%) and were less likely to have DKA (7.8% vs. 35.0%) and diabetes autoantibodies (5.5% vs. 95.4%). Children with T2D also had significantly lower glucose, lower hemoglobin A1c and lower C-peptide level (all comparisons, p<0.0001). In multiple logistic regression analysis, older age, racial/ethnic minority, obesity, higher C-peptide, and negative islet autoantibodies were independently associated with T2D (all, p<0.05), while sex, glucose, hemoglobin A1c, and DKA were not (model p<0.0001).
Conclusion
There are important demographic, clinical, and laboratory differences between T1D and T2D in children. However, none of the characteristics were unique to either diabetes type, which poses challenges to diabetes classification at diagnosis.

BACKGROUND AND OBJECTIVES: Zehneria japonica belongs to the Cucurbitaceae family which is one of the most important plant families. It is commonly known as "Pipinong-gubat," widely distributed in Central Luzon regions and in areas along streams and clearings at low and medium altitudes in the Philippines. This study aimed to evaluate the potential cytotoxic and angiosuppressive properties of Zehneria japonica (Thunb. ex Murray) S.K. Chen (Cucurbitaceae) leaf extracts.
METHODOLOGY: The Z japonica semi-crude extracts were obtained by sequential extraction using hexane, ethyl acetate, and n-butanol. A modified duck egg chorioallantoic membrane (CAM) assay was aided by AngioQuant, a digital imaging software used to evaluate angiogenic activity. Inhibition of angiogenesis was evaluated by percent increase or decrease in mean length of blood vessels, mean size of blood vessels, and total number of blood vessel junctions. Moreover, the cytotoxic effects of the extracts were determined through MTT Assay. Osteosarcoma (U20s) and hepatocellular carcinoma (HepG2) cells were used as cancer representatives while human umbilical vein endothelial cells (HUVEC) were used as the normal cell control.
RESULTS: Analysis with AngioQuant revealed that treatment of the duck egg CAM with Z. japonica semi-crude extracts suppressed angiogenesis with ICso values of 1,810.00 ug/mL, 192.50 ug/ml, and 147.70 ug/mL for hexane, ethyl acetate, and n-butanol, respectively, with Celecoxib (20 ug/mL) as the positive control. For MTT assay, Z. japonica extracts exhibited strong cytotoxic effect against U2Os with an ICso values of 19.65 ug/mL, 9.89 ug/ml, and 31.04 ve/mL for the hexane, ethyl acetate, and n-butanol extracts, and no cytotoxic effects against HepG2 with IC50 values of 770.90 ug/mL, 130.10 ug/mL and 231.60 ug/mL for the hexane, ethyl acetate, and n-butanol extracts. Doxorubicin (0.544 ug/mL) was used as the positive control. The extracts also inhibited the growth of the normal cells, with IC50 values of 69.46 ng/mL, 42.23 ug/mL and 63.44 ug/mL for the hexane, ethyl acetate, and n-butanol extracts. There were no mortality and toxic symptoms observed for 14 days after the administration of the crude butanolic extract of Z. japonica in six female Sprague Dawley rats.
CONCLUSION: Z. japonica crude leaf extracts exhibited angio-suppressive activity through CAM assay. In MTT assay, the extracts exhibited strong cytotoxicity in U20s (IC50 S20 ug/mL), no cytotoxic effect in HepG2 (ICso >100 ug/mL) cells, and mild cytotoxic effect in HUVEC (IC50 40-60 ug/mL). Phytochemical screening through TLC revealed that the extracts contain alkaloids, anthrones, flavonoids, and sterols.

Background and Objective:
Convalescent plasma therapy (CPT) may reduce the risk of disease progression among patients with COVID-19. This study was undertaken to evaluate the efficacy and safety of CPT in preventing ICU admission among hospitalized COVID-19 patients.
Methods:
In this open-label randomized controlled trial, we randomly assigned hospitalized adult patients with
COVID-19 in a 1:1 ratio to receive convalescent plasma as an adjunct to standard of care or standard of care alone. The primary endpoint was ICU admission within first 28 days of enrolment. Primary safety endpoints include rapid deterioration of respiratory or clinical status within four hours of convalescent plasma transfusion and cumulative incidence of serious adverse events during the study period including transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), severe allergic reactions, and transfusion-related infections.
Results:
A total of 22 patients were assigned to receive convalescent plasma as an adjunct to standard of care and 22 to receive standard of care alone. The median time from onset of COVID-19 symptoms to study enrolment was eight days (IQR, 4 to 10). Two patients (9.1%) in the CPT group and one patient (4.5%) in the control group were admitted to the ICU. The primary outcome measure, ICU admission, was not different between the two groups (q-value >0.9). No patient who received convalescent plasma had rapid deterioration of respiratory/clinical status within four hours of transfusion and none developed TRALI, TACO, anaphylaxis, severe allergic reactions, or transfusion-related infections. There was also no significant difference in the secondary outcomes of 28-day mortality (two patients in the CPT group and none in the control group, q-value >0.90), dialysis-free days, vasopressor-free days, and ICU-free days.
Conclusions
Among hospitalized COVID-19 patients, no significant differences were observed in the need for
ICU admission between patients given CPT as adjunct to standard of care and those who received standard of
care alone. Interpretation is limited by early termination of the trial which may have been underpowered to
detect a clinically important difference.
