RESUMO

INTRODUCTION: In the early parts of the COVID-19 pandemic, non-pharmaceutical interventions (NPIs) were implemented worldwide, including in sub-Saharan Africa, to prevent and control SARS-CoV-2 transmission. This mixed-methods study examines adherence to and enforcement of NPIs implemented to curb COVID-19 in Nigeria, Rwanda, and Zambia, leading up to the 10,000th case of laboratory-confirmed COVID-19 in each country. Additionally, we aim to evaluate the relationship between levels and changes of NPIs over time and changes in COVID-19 cases and deaths. METHODS: This mixed-methods analysis utilized semi-structured interviews and a quantitative dataset constructed using multiple open data sources, including the Oxford COVID-19 Government Response Tracker. To understand potential barriers and facilitators in implementing and enforcing NPIs qualitative data were collected from those involved in the COVID-19 response and analyzed using NVivo. Quantitative results were analyzed using descriptive statistics, plots, ANOVA, and post hoc Tukey. RESULTS: Individual indicator scores varied with the COVID-19 response in all three countries. Nigeria had sustained levels of strict measures for containment and closure NPIs, while in Rwanda there was substantial variation in NPI score as it transitioned through the different case windows for the same measures. Zambia implemented moderate stringency throughout the pandemic using gathering restrictions and business/school closure measures but maintained low levels of strictness for other containment and closure measures. Rwanda had far more consistent and stringent measures compared to Nigeria and Zambia. Rwanda's success in implementing COVID-related measures was partly due to strong enforcement and having a population that generally follow the recommendations of their government. CONCLUSION: Various forces either facilitated or hindered adherence and compliance to COVID-19 control measures. The lessons learned and recommendations gleaned through interviews with experts involved in the COVID-19 pandemic and quantitative analysis of NPI implementation can be applied to future outbreaks, epidemics, and pandemics. Recommendations include engaging communities, using a risk-based approach to implement containment and closure NPIs, and providing social and economic support to citizens during periods of lockdowns and other measures that interrupt the ability to make a living.

RESUMO

We propose the term "pan-epidemic Anthropocene" to refer to multifocal infectious disease epidemics related to human-caused (anthropogenic) forces such as urbanization, globalization, industrialization and the growing populations of humans and animals. The integrated framework of One Health (human, animal, and environmental health) helps both to understand why epidemics occur when and where they do, and also how to respond, mitigate, and sometimes prevent them. We suggest a collaborative mechanism for increasing One Health in medical education to create a synergy of strengths between the growing number of contributing One Health organizations in the US and internationally.

RESUMO

There are few case reports of infections caused by Brevibacterium species, and there have been no previously reported cases of endocarditis caused by any of the 6 known species of Brevibacterium. We report the first case of Brevibacterium endocarditis (caused by Brevibacterium otitidis) in a patient with prosthetic heart valves. The patient responded to 6 weeks of treatment with vancomycin and 2 weeks with gentamicin, and she has been receiving long-term maintenance therapy with oral azithromycin.

RESUMO

Strongyloides hyperinfection syndrome may be complicated by paralytic ileus that interferes with the absorption of oral anti-helminthics. We report on the administration of ivermectin as a rectal enema preparation to a renal transplant recipient with Strongyloides hyperinfection syndrome and progressive ileus. Attempts at treatment using nasogastric albendazole and ivermectin were unsuccessful despite clamping the nasogastric tube after drug administration. Ivermectin tablets were ground to a powder, resuspended in a commercially available suspending agent, and administered per rectum. The suspending agent was chosen for its near-physiologic osmolality to allow longer retention, in contrast to many enema preparations that have a laxative effect. The patient improved markedly within 72 hours of initiation of the therapy per rectum and recovered fully. Ivermectin administered as an enema may be beneficial in patients with severe strongyloidiasis who are unable to absorb or tolerate oral therapy.

RESUMO

Enterococci are a major cause of bacteraemia and endocarditis and are increasingly being implicated in bone and joint infections. Hematogenous enterococcal vertebral osteomyelitis, however, has been only rarely reported. Here we present the first 2 patients from the United States and review the literature on 10 additional cases that have been published since 1967. The clinical presentation of enterococcal vertebral osteomyelitis was similar to cases due to other bacteria. Enterococcus faecalis caused most cases, consistent with its presumably increased virulence. All enterococcal cases in the literature were reported from Europe, which may be due to epidemiological differences related to antibiotic utilization and infection control practices between the US and Europe. Nine of all 12 cases were reported since 1995, which may be consistent with the increase in occurrence of enterococcal infections in general, in association with increasing patient co-morbidities, invasive procedures, and indwelling vascular devices.

RESUMO

Cutaneous fungal infections in solid-organ transplant patients present in a variety of nonspecific ways, requiring a high index of suspicion to diagnose correctly. In the present series of four transplant recipients, subsequent primary cutaneous fungal infections presented as papules, plaques, ulcers and subcutaneous nodules. Transplantations included one cardiac, two renal and one renal-pancreatic transplant. Fungal infections were limited to the skin; there was no evidence of disseminated disease in any case. The pathogens isolated were Scedosporium apiospermum (Pseudallescheria boydii), Alternaria species, Aspergillus fumigatus, and a coelomycete in the Coniothyrium-Microsphaeropsis complex of dark molds. Individuals were successfully treated with surgical debridement, antifungal agents, and reduction of immunosuppressive therapy. All patients and allografts survived. Accurate diagnosis, aggressive surgery and appropriate antifungal therapy, combined with close outpatient follow-up, optimize the likelihood of a cure in a transplant population.

RESUMO

A rapid (time to completion, <4 h, including DNA extraction) and quantitative touch-down (QTD) real-time diagnostic Pneumocystis carinii PCR assay with an associated internal control was developed, using fluorescence resonance energy transfer (FRET) probes for detection. The touch-down procedure significantly increased the sensitivity of the assay compared to a non-touch-down procedure. Tenfold serial dilutions of a cloned target were used as standards for quantification. P. carinii DNA has been detected in respiratory specimens from patients with P. carinii pneumonia (PCP) and from patients without clinical evidence of PCP. The latter probably represents colonization or subclinical infection. It is logical to hypothesize that quantification might prove helpful in distinguishing between infected and colonized patients: the latter group would have lower copy numbers than PCP patients. A blinded retrospective study of 98 respiratory samples (49 lower respiratory tract specimens and 49 oral washes), from 51 patients with 24 episodes of PCP and 34 episodes of other respiratory disease, was conducted. PCR-positive samples from colonized patients contained a lower concentration of P. carinii DNA than samples from PCP patients: lower respiratory tract samples from PCP and non-PCP patients contained a median of 938 (range, 2.4 to 1,040,000) and 2.6 (range, 0.3 to 248) (P < 0.0004) copies per tube, respectively. Oral washes from PCP and non-PCP patients contained a median of 49 (range, 2.1 to 2,595) and 6.5 (range, 2.2 to 10) (P < 0.03) copies per tube, respectively. These data suggest that this QTD PCR assay can be used to determine if P. carinii is present in respiratory samples and to distinguish between colonization and infection.
