Objective :
To identify the main components in the extracts of different parts of Juandan Baihe (Lilium lancifolium) by ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) technology and investigate their hypoglycemic activities.
Methods:
The MS fragmentation pathways of the main types of compounds in Juandan Baihe (Lilium lancifolium) were studied, and the main components in the extracts were systematically identified using MS fragmentation pathways combined with MS mining technology. Based on the hyperglycemia male mouse model [specific pathogen free (SPF)-grade Kunming mice] induced by streptozotocin (intragastric administration of 80 mg/kg for 3 d), the hypoglycemic effects of extracts of Juandan Baihe (Lilium lancifolium) roots, stems, corms, leaves, and flowers were evaluated by measuring the changes of blood glucose, daily water consumption, daily food intake, and body weight.
Result:
The MS fragmentation pathways of regalosides, dioscins, phenylpropanoids, flavonoids, and chlorogenic acids in Juandan Baihe (Lilium lancifolium) were clarified, and a mining method for compounds in this plant was constructed. A total of 58 compounds, including 6 chlorogenic acids, 14 regalosides, 13 phenylpropanoids, 5 flavonoids, and 20 dioscins, were identified from the roots, stems, corms, leaves, and flowers of Juandan Baihe (Lilium lancifolium). Among them, 30 compounds were reported for the first time from this plant. The root and corm extracts demonstrated significant hypoglycemic activities by reducing blood glucose levels from 23.76 ± 1.21 and 24.29 ± 1.35 mmol/L to 17.21 ± 1.23 and 18.78 ± 1.49 mmol/L, respectively (P < 0.05). The roots and corms extracts could also attenuate the symptoms of polydipsia (P < 0.01), polyphagia (P < 0.05), and weight loss caused by diabetes.
Conclusion
This study clarifies that the roots of Juandan Baihe (Lilium lancifolium) are rich in regalosides and dioscins for the first time, and have significant hypoglycemic activities, providing the foundation for the comprehensive utilization of this plant and the development of hypoglycemic drugs.

Objectives: The Pharmacy DOTS Initiative (PDI) was relaunched on a larger scale in 2014 through the Innovations and Multi-Sectoral Partnerships to Achieve Control of Tuberculosis (IMPACT) project. This paper aimed to assess the PDI program through IMPACT by identifying the facilitating and hindering factors in its implementation. The identified factors are classified as to the affected stakeholders or processes.
Methods: Semi-structured interviews were conducted with the PDI Program Manager and four NTP coordinators from selected project sites. Thematic analysis was done to determine the recurring facilitating and hindering factors as identified by the key informants.
Results: Facilitating factors identified include cooperation of the stakeholders, capability-building and a good referral system. The barriers to the implementation were grouped into patient-related, pharmacy-related, health center-related, program-related as well as external factors.
Conclusion: The referral system created through PDI facilitated the flow of referrals starting from the pharmacy. This enabled presumptive patients to have access to health facilities for TB. Hindering factors contributed to the inability of the engaged pharmacies to sustain their consistency and commitment in conducting the PDI interventions.

Background and Objectives: Tuberculosis (TB) remains a public health problem in the Philippines despite trends indicating a decline in the burden of disease. Persons who use drugs who are confined in government-retained drug abuse treatment and rehabilitation centers (DATRCs) face an increased risk for TB because of the congestion in the facility coupled with the absence of guidelines on TB management specific to DATRCs. Thus, this study was conducted to document the current case finding and case holding practices as well as TB treatment pathway in six (6) Luzon-based, government-retained DATRCs.
Methods: Key informant interviews were conducted with DATRC personnel involved in TB diagnosis and management in six selected DATRCs in Luzon, Philippines. Interviews were transcribed and coded for thematic analysis. We compared the DATRC practices with the provisions of the 2014 National TB Control Program (NTP) Manual of Procedures. Results were validated through a workshop with (a) a group of physicians and rehabilitation practitioners assigned in other DATRCs; and (b) a group of experts who have experience in managing or overseeing DATRCs in the country.
Results: Two physicians and four nurses participated in the interviews. Variations in case finding and case holding practices in six DATRCs have been found. National guidelines exist for congregate settings but are more specific to jails/prisons, which are administratively and operationally different from DATRCs.
Conclusion: Development of special guidelines for TB case finding and case holding in DATRCs as well as staff training on the latest NTP Manual of Procedures are recommended. However, gaps and inequities posed by the current set-up underscore the need to address health system-wide factors affecting the practice and performance of these facilities.

Objective: This paper aims to characterize existing financial assistance available to patients with schizophrenia. Specifically, we described (1) the funding mechanisms for the treatment of patients with schizophrenia; (2) the process for accessing financial assistance; and (3) the experiences of consumers of services of these support mechanisms.
Methods: We employed qualitative techniques using key informant interviews (KII) and focus group discussion (FGD). Key informants were officials from institutions providing or offering financial assistance for patients with any health-related concerns, including schizophrenia. Focus group participants were support group members or caregivers of patients with schizophrenia. Purposive sampling was used to select participants for both providers and consumers of financial assistance or scheme. Topic guides for KII and FGD were used for data collection. Thematic analysis was performed on the qualitative data gathered from the informants and focus group participants.
Results: Securing financial assistance for schizophrenia followed a generally similar process, whether the source is from government offices or civil society organizations, and can be grouped into three main stages: (a) pre-application, (b) application, and (c) post-application. While the process of seeking financial assistance appears to be straightforward, issues were encountered in all of the stages by both providers and recipients alike, namely: (a) Financial assistance as an augmentation to patient resources; (b) Mismatch between demand and service capability; (c) Measures of organizational effectiveness; (d) Health professionals and support groups as "bridges" / "facilitators" to financial assistance providers; (e) Financial and non-financial costs incurred by caregivers in applying for financial assistance; and (f) Recipient-provider relationship as a barrier to the feedback process.
Conclusion: This study provides a glimpse of available financial and other relevant assistance to clients, including clients suffering from schizophrenia. More extensive research covering more organizations, support groups, and caregivers from different parts of the country is recommended.

Background and Objectives: The Philippine Department of Health (DOH) is mandated by law to, among others, develop capacities and accredit physicians and rehabilitation practitioners across the country on the assessment and management of drug dependence. This paper describes the design and presents the outputs of an advanced course on screening and assessment of drug dependence developed by DOH in partnership with the College of Public Health of the University of the Philippines Manila, Philippine College of Addiction Medicine, and the Group for Addiction Psychiatry of the Philippines.
Methodology: Review, abstraction and synthesis of data from training-related documents and records for the training activities implemented in 2014.
Results: The Level 2a course is a five-day program that focuses on enhancing the skills of physicians and rehabilitation practitioners on the screening and assessment of drug dependence using team-based and practical learning approaches, and builds on learnings from the basic accreditation course. A total of 36 participants from ten Drug Abuse Treatment and Rehabilitation Centers (DATRCs) in nine regions completed the pilot implementation of the course in 2014. In general, the overall participant feedback on the training was mainly favorable based on data from 47% of participants who agreed or strongly agreed to statements on the relevance and attainment of the course aims (mean rating of 1.10±0.31, 1 = Strongly agree, 5 = Strongly disagree), and the appropriateness of its content (1.24±0.43) and design (1.18±0.39). A paired-samples t-test comparing scores for 44% of participants showed that there was a highly statistically significant difference in the pre-test (54%±13%) and post-test scores (69%±10%); t(16)=6.4240, p <0.0001.
Conclusion: Development and design of capability-building initiatives in the field of drug rehabilitation will necessitate alignment with practice standards, grounding in the real-world setting in which professionals work, and orientation towards practical learning.

Philippine Journal of Health Research and Development 2022;26(2):77-80
Sample size computations, which should be done at the planning stage of the study, are necessary for
research to estimate a population parameter or test a hypothesis. For causal analysis of observational
databases, sample size computations are generally not needed. Post-hoc power analyses, which are typically done with non-significant findings, should not be performed since reporting post-hoc power is nothing more than reporting p values differently. While sample size calculations are typically based on the tradition of significance testing, sample size calculations based on precision are feasible – if not preferred – alternatives. Sample size calculations depend on several factors such as the study objective, scale of measurement of the outcome variable, study design, and sampling design. Computing for sample size is not as straightforward as presented in textbooks but specific strategies may be resorted to in the face of challenges and constraints.

Although genome-wide association studies have identified more than eighty genetic variants associated with non-small cell lung cancer (NSCLC) risk, biological mechanisms of these variants remain largely unknown. By integrating a large-scale genotype data of 15 581 lung adenocarcinoma (AD) cases, 8350 squamous cell carcinoma (SqCC) cases, and 27 355 controls, as well as multiple transcriptome and epigenomic databases, we conducted histology-specific meta-analyses and functional annotations of both reported and novel susceptibility variants. We identified 3064 credible risk variants for NSCLC, which were overrepresented in enhancer-like and promoter-like histone modification peaks as well as DNase I hypersensitive sites. Transcription factor enrichment analysis revealed that USF1 was AD-specific while CREB1 was SqCC-specific. Functional annotation and gene-based analysis implicated 894 target genes, including 274 specifics for AD and 123 for SqCC, which were overrepresented in somatic driver genes (ER = 1.95, P = 0.005). Pathway enrichment analysis and Gene-Set Enrichment Analysis revealed that AD genes were primarily involved in immune-related pathways, while SqCC genes were homologous recombination deficiency related. Our results illustrate the molecular basis of both well-studied and new susceptibility loci of NSCLC, providing not only novel insights into the genetic heterogeneity between AD and SqCC but also a set of plausible gene targets for post-GWAS functional experiments.
