ABSTRACT
INTRODUCTION: The COVID-19 pandemic has emerged as one of the greatest challenges to societies, world health systems and science in the past century, making it imperative to restructure care networks. Therefore, it is essential to discuss the role and initiatives of primary health care (PHC) to deal with it. However, regarding the response to the pandemic, including the current global effort against COVID-19, the nuances of the rural/remote PHC context in the pandemic is barely visible. Rural and remote communities have differentiated health risks, such as socioeconomic disadvantages, difficulties in mobility and access to health services, in addition to linguistic and cultural barriers. This scoping review aimed to analyze the set of individual and collective initiatives and innovations developed to face the COVID-19 pandemic, within the PHC scope, in rural and remote areas. METHODS: A scoping review methodology was applied to peer-reviewed articles. Eight databases were searched to identify scientific articles published in English, Spanish and Portuguese, initially from January 2020 to July 2021, complemented by a rapid review of articles published from January 2022 to April 2023. The main focus sought in the literature was the set of initiatives and innovations carried out within the PHC scope in rural and remote locations during the pandemic, as well as the comparison with pre-pandemic situations and between different countries. The bibliographic information of each search result was imported into Rayyan (Intelligent Systematic Review), followed by the screening and eligibility stages, performed independently by two reviewers, with a third reviewer being accessed in case of conflicts. RESULTS: This review included 54 studies, with publications mostly from Australia, Canada, the US and India. The main PHC initiatives were related to access; to the roles of community health workers and health surveillance; and to the importance of placing, retaining and valuing human resources in health. Cultural, equity and vulnerability issues occupy a major place among the initiatives. Regarding the innovations, telehealth and customized communication are highlighted. From an organizational point of view, rural and remote locations showed enormous flexibility to deal with the pandemic and to improve intersectoral activities at the local level. The description of rurality and remoteness is practically coincident with that of the specific populations, present in geographic areas of difficult sociospatial and cultural access. Rarely, there is an index to measure rurality, or its description deals with the need to overcome distances and obstacles. CONCLUSION: The findings highlight and summarize knowledge about initiatives and innovations developed to face the COVID-19 pandemic, within the PHC scope in rural and remote areas in the world. This review has identified collective, clinical, intersectoral and, mainly, organizational health initiatives. An articulation between different government levels would be paramount in evaluating the implementation of policies and protocols in rural and remote locations for future sanitary crises. Innovations and lessons learned are equally relevant in strengthening health services and systems. This issue calls for considerable further exploration by new reviews and empirical research that seek evidence to assess the sustainability and effectiveness of the implemented measures to face post-pandemic difficulties and other adversities.

Disseminated histoplasmosis (DH) is endemic in Latin America and the Caribbean where diagnostic tools are restricted. We carried-out a 1-year prospective cohort study at a referral hospital in São Paulo, Brazil. Participants had > or =18 years old, were hospitalized due to any indication and had CD4+ < 200 cells/µl. A urine commercial monoclonal Histoplasma galactomannan enzyme-linked immunosorbent assay (IMMY, Norman, OK, USA) and 'in house' Histoplasma blood nested PCR were performed in all cases. Probable/proven DH cases were defined according to international guidelines. Conventional mycological methods were available in routine conditions to investigate suspected DH cases. Treatment of participants followed the institutional routine. One-hundred six participants were included. Median age (interquartile range [IQR]) was 39.5 years (30.0-47.3) and 80 individuals (75.5%) were males. Median (IQR) CD4 cell count was 26.5 (9.4-89.3) cells/mm3. DH was diagnosed in 8/106 patients (7.5%). Antigen assay and/or PCR were positive in 4.7% (5/106) of patients. The antigen assay and/or PCR identified 37.5% (3/8) of DH cases, which had not been diagnosed with conventional mycological methods, but had clinical manifestations compatible with HD. In conclusion, the use of Histoplasma urine antigen and Histoplasma blood PCR guided by CD4 status contributed to the diagnosis of DH in hospitalized individuals. These assays were complementary to conventional mycologic methods and are urgently needed in our setting. LAY SUMMARY: In this prospective cohort study carried-out in a referral center in São Paulo, Brazil, we found a high frequency of AIDS-related disseminated histoplasmosis (8/106, 7.5%). We used urine antigen test and blood PCR assay to improve the diagnosis of this opportunistic disease.
