BACKGROUND Primary health care (PHC) outreach teams are part of a policy of PHC re-engineering in South Africa. It attempts to move the deployment of community health workers (CHWs) from vertical programmes into an integrated generalised team-based approach to care for defined populations in municipal wards. There has little evaluation of PHC outreach teams. Managers' insights are anecdotal. ...

Nurses in primary health care (PHC) provide an increasing proportion of chronic disease management and preventive lifestyle advice. The databases MEDLINE, CINAHL, EMBASE and PsychINFO were searched and the articles were systematically reviewed for articles describing controlled adult lifestyle intervention studies delivered by a PHC nurse, in a PHC setting. Thirty-one articles describing 28 stu...

The re-engineering of primary healthcare (PHC) is regarded as an essential precursor to the implementation of National Health Insurance in South Africa, but improvements in the provision of PHC services have been patchy. The authors contend that the role of well- functioning rural district hospitals as a hub from which PHC services can be most efficiently managed has been underestimated, and th...

Portal hypertensive colopathy (PHC) is a new clinical entity in patients with liver cirrhosis. In this study, colonoscopic findings and clinical features including upper gastrointestinal endoscopy and hepatic hemodynamics were prospectively investigated among 35 PH patients with a hepatic venous pressure gradient (HVPG) of greater than 12 mmHg due to chronic liver diseases. Colonoscopy was also...

Preventive Health Care (PHC) is the awareness and efforts a person undertakes to enhance and preserve physical, mental, and emotional health for today and the future. This research examines the importance of online delivery systems as sources of PHC information. It examines how health care consumers respond to various online PHC delivery systems, with a special emphasis on social media (SM). Sp...

Silicon nanophotonics has recently attracted great attention since it offers an opportunity for low cost opto-electronic solutions based on silicon complementary metal oxide semiconductor (MOS) technology. Photonic crystal (PhC) structures with slow photon effect are expected to play a key role in future large-scale ultra-compact photonic integrated circuits. A novel vertical-MOS-capacitor-base...

Little research has been conducted to date on the role of primary health care (PHC) in the prevention of healthcare associated infections (HCAIs). The present article is a theoretical study of the principle of primum non nocere and aims to promote reflection on the role of PHC in HCAI prevention with emphasis on practical recommendations. The indirect and direct roles of PHC in HCAI prevention ...

BACKGROUND Primary health care is recognised as an integral part of a country's health care system. Measuring hospitalisations, that could potentially be avoided with high quality and accessible primary care, is one indicator of how well primary care services are performing. This review was interested in the association between chronic disease related hospitalisations and primary health care re...

In this paper, by integrating InP/InGaAsP/InP Photonic crystal semiconductor optical amplifier (PhC-SOA) with photonic channel drop filters (PhC-CDF), we present a novel fully integrated ultra-small low-power all-optical analog to digital converter (AO-ADC). The self-phase modulation in the PhC-SOA can shift frequency of Gaussian input pulse. two output PhC-CDFs are designed way that appropriat...

We present the design and simulation of an ultra-compact polarization beam splitter (PBS) by combining a photonic crystal (PhC) multimode waveguide and an internal PhC section. The PhC multimode waveguide is designed to collect the powers reflected by or transmitted through the internal PhC structure which serves as a polarization sensitive scatterer. Plane wave expansion (PWE) method is used t...
