Background And Objective: Staffing shortages and health inequities are persistent barriers in the Philippines toward achieving universal health care. To ensure an adequate and responsive health workforce, there is a need to evaluate the Human Resources for Health (HRH) status across health facilities, particularly those in underserved communities. Hence, this study aims to determine the staffing requirements and workload pressure among primary care facilities in selected geographically isolated and disadvantaged areas (GIDAs) in the Philippines.

Background: The COVID-19 pandemic has caused extraordinary disruptions to education systems globally, forcing a rapid switch from conventional to online education. Although some qualitative studies have been carried out exploring the online education experiences of nursing students and faculty members during the COVID-19 pandemic, to our knowledge, no study has used the Photovoice approach.

Objectives: To explore the experiences of nursing students and faculty members as related to online education during the COVID-19 pandemic.

Background: A Chrysodeixis chalcites nucleopolyhedrovirus from the Canary Islands (ChchNPV-TF1) has proved to be effective for control of Chrysodeixis chalcites on banana crops. Commercialization of this virus as a bioinsecticide requires an efficient production system.

Results: The sixth instar (L ) was the most suitable for virus production, producing 1.

Background: Chrysodeixis chalcites (Esper) is a major pest of tomato in Mediterranean countries and attacks banana in the Canary Islands (Spain). The efficacy of Chrysodeixis chalcites single nucleopolyhedrovirus (ChchSNPV-TF1) was evaluated in plant growth chambers and greenhouse trials performed on tomato and banana plants respectively. Treatments were applied using a compressed air sprayer.

The Chrysodeixis chalcites single nucleopolyhedrovirus (ChchSNPV) infects and kills C. chalcites larvae, an important pest of banana crops in the Canary Islands. Five genotypes present in the most prevalent and widespread isolate in the Canary Islands were sequenced, providing genetic data relevant to the genotypic and phenotypic diversity of this virus.

A Chrysodeixis chalcites single-nucleocapsid nucleopolyhedrovirus wild-type isolate from the Canary Islands, Spain, named ChchSNPV-TF1 (ChchTF1-wt), appears to have great potential as the basis for a biological insecticide for control of the pest. An improved understanding of the genotypic structure of this wild-type strain population should facilitate the selection of genotypes for inclusion in a bioinsecticidal product. Eight genetically distinct genotypes were cloned in vitro: ChchTF1-A to ChchTF1-H.

Background: Chrysodeixis chalcites is a major noctuid pest of banana crops in the Canary Islands. The stage-specific susceptibility of this pest to C. chalcites single nucleopolyhedrovirus (ChchSNPV-TF1) was determined, as well as the effect of selected optical brighteners as enhancers of primary infection.

The University of the Philippines College of Nursing curriculum has been the foundation of most of the curriculum in the country. But such is inferior with the current global health care delivery system. With Telehealth as the current program launched as an alternative medium to address health-care needs in geographically isolated areas through the use of ICT, nurses provide care for populations through electronic communication media and act as triage nurses who advise/consult with patients.

The University of the Philippines National Telehealth Center extended its services to the Doctor-to-the-Barrios program of the Department of Health through Short Messaging System telereferral system. This system enables physicians from remote and underserved rural communities to refer cases to domain experts from the University of the Philippines Philippine General Hospital. Two hundred eighty-four cases were sent in a six-month period.
