RESUMEN

Shared medical appointments (SMAs) offer a means for providing knowledge and skills needed for chronic disease management to patients. However, SMAs require a time and attention investment from health care providers, who must understand the goals and potential benefits of SMAs from the perspective of patients and providers. To better understand how to gain provider engagement and inform future SMA implementation, qualitative inquiry of provider experience based on a knowledge-attitude-practice model was explored. Semi-structured interviews were conducted with 24 health care providers leading SMAs for heart failure at three Veterans Administration Medical Centers. Rapid matrix analysis process techniques including team-based qualitative inquiry followed by stakeholder validation was employed. The interview guide followed a knowledge-attitude-practice model with a priori domains of knowledge of SMA structure and content (understanding of how SMAs were structured), SMA attitude/beliefs (general expectations about SMA use), attitudes regarding how leading SMAs affected patients, and providers. Data regarding the patient referral process (organizational processes for referring patients to SMAs) and suggested improvements were collected to further inform the development of SMA implementation best practices. Providers from all three sites reported similar knowledge, attitude and beliefs of SMAs. In general, providers reported that the multi-disciplinary structure of SMAs was an effective strategy towards improving clinical outcomes for patients. Emergent themes regarding experiences with SMAs included improved self-efficacy gained from real-time collaboration with providers from multiple disciplines, perceived decrease in patient re-hospitalizations, and promotion of self-management skills for patients with HF. Most providers reported that the SMA-setting facilitated patient learning by providing opportunities for the sharing of experiences and knowledge. This was associated with the perception of increased comradery and support among patients. Future research is needed to test suggested improvements and to develop best practices for training additional sites to implement HF SMA.

RESUMEN

CONTEXT: Pain in sport has been normalized to the point where athletes are expected to ignore pain and remain in the game despite the possible detrimental consequences associated with playing through pain. While rehabilitation specialists may not have an influence on an athlete's competitive nature or the culture of risk they operate in, understanding the consequences of those factors on an athlete's physical well-being is definitely in their area of responsibility. OBJECTIVE: To explore the factors associated with the experiences of subelite athletes who play through pain in gymnastics, rowing, and speed skating. DESIGN: The authors conducted semistructured interviews with subelite athletes, coaches, and rehabilitation specialists. They recruited coach participants through their provincial sport organization. Athletes of the recruited coaches who were recovering from a musculoskeletal injury and training for a major competition were then recruited. They also recruited rehabilitation specialists who were known to treat subelite athletes independently by e-mail. SETTING: An observation session was conducted at the athlete's training facility. Interviews were then conducted either in a room at the university or at a preferred sound-attenuated location suggested by the participant. PARTICIPANTS: The authors studied 5 coaches, 4 subelite athletes, and 3 rehabilitation specialists. INTERVENTIONS: The authors photographed athletes during a practice shortly before an important competition, and we interviewed all the participants after that competition. Our photographs were used during the interview to stimulate discussion. RESULTS: The participant interviews revealed 3 main themes related to playing through pain. They are: Listening to your body, Decision making, and Who decides. CONCLUSION: When subelite athletes, striving to be the best in their sport continue to train with the pain of an injury, performance is affected in the short-term and long-term consequences are also possible. Our study provides some insight into the contrasting forces that athletes balance as they decide to continue or to stop.

RESUMEN

OBJECTIVE: Cannabis (marijuana) is undergoing extensive regulatory review in many global jurisdictions for medical and nonmedical access. Cannabis has potential impact on the health of athletes as well as on performance in both training and in competition. The aim of this general review is to identify and highlight the challenges in interpreting information with respect to elite athletic performance, and to point to important research areas that need to be addressed. DATA SOURCES: A nonsystematic literature review was conducted using Medline and PubMed for articles related to cannabis/marijuana use and sports/athletic performance; abstracts were reviewed by lead author and key themes identified and explored. MAIN RESULTS: Cannabis may be primarily inhaled or ingested orally for a range of medical and nonmedical reasons; evidence for efficacy is limited but promising for chronic pain management. Although evidence for serious harms from cannabis use on health of athletes is limited, one should be cognizant of the potential for abuse and mental health issues. Although the prevalence of cannabis use among elite athletes is not well-known, use is associated with certain high-risk sports. There is no evidence for cannabis use as a performance-enhancing drug. CONCLUSIONS: Medical and nonmedical cannabis use among athletes reflects changing societal and cultural norms and experiences. Although cannabis use is more prevalent in some athletes engaged in high-risk sports, there is no direct evidence of performance-enhancing effects in athletes. The potential beneficial effects of cannabis as part of a pain management protocol, including reducing concussion-related symptoms, deserve further attention.

RESUMEN

OBJECTIVE: To determine the therapeutic efficacy of artesunate + sulphadoxine/pyrimethamine (AS + SP) and artemether + lumefantrine (AL), and to investigate the presence of molecular mutations associated with resistance, to inform national malaria treatment policy. METHODS: One-arm prospective studies were conducted in three study sites in Somalia in 2013 and 2015 to evaluate the efficacy of AS + SP and AL among patients with uncomplicated falciparum malaria. Outcomes included clinical and parasitological response over 28 days, and the presence of dihydrofolate reductase (dfhr) and dihydropteroate synthase (dhps) and mutations. RESULTS: Among patients treated with AS + SP, the PCR-corrected treatment failure rate was 12.3%. The majority of patients (89%) carried either the quintuple mutations (51I/108N + 437G/540E/581G or 51I/59R/108N + 437G/540E) or the quadruple mutation (51I/108N + 437G/540E). All patients who failed treatment with AS + SP carried the quintuple mutation (51I/108N + 437G/540E/581G). In the studies of AL, the PCR-corrected treatment failure rate was <6%. All patients in both treatment groups cleared their parasitaemia by day 3. CONCLUSIONS: The findings demonstrate a failing first-line treatment (AS + SP), with a failure rate above the threshold (10%) for policy change, and a high prevalence of quintuple mutations. In contrast, AL was highly efficacious. Based on these findings and the results from a previous AS + SP study, AL was selected to replace AS + SP as the first-line treatment for uncomplicated malaria in Somalia in 2016. Dihydroartemisinin + piperaquine (DHA + PPQ) has been recommended as the second-line treatment. Routine monitoring of recommended ACTs should continue to inform treatment policy.

RESUMEN

BACKGROUND: 2015 was the target year for malaria goals set by the World Health Assembly and other international institutions to reduce malaria incidence and mortality. A review of progress indicates that malaria programme financing and coverage have been transformed since the beginning of the millennium, and have contributed to substantial reductions in the burden of disease. FINDINGS: Investments in malaria programmes increased by more than 2.5 times between 2005 and 2014 from US$ 960 million to US$ 2.5 billion, allowing an expansion in malaria prevention, diagnostic testing and treatment programmes. In 2015 more than half of the population of sub-Saharan Africa slept under insecticide-treated mosquito nets, compared to just 2 % in 2000. Increased availability of rapid diagnostic tests and antimalarial medicines has allowed many more people to access timely and appropriate treatment. Malaria incidence rates have decreased by 37 % globally and mortality rates by 60 % since 2000. It is estimated that 70 % of the reductions in numbers of cases in sub-Saharan Africa can be attributed to malaria interventions. CONCLUSIONS: Reductions in malaria incidence and mortality rates have been made in every WHO region and almost every country. However, decreases in malaria case incidence and mortality rates were slowest in countries that had the largest numbers of malaria cases and deaths in 2000; reductions in incidence need to be greatly accelerated in these countries to achieve future malaria targets. Progress is made challenging because malaria is concentrated in countries and areas with the least resourced health systems and the least ability to pay for system improvements. Malaria interventions are nevertheless highly cost-effective and have not only led to significant reductions in the incidence of the disease but are estimated to have saved about US$ 900 million in malaria case management costs to public providers in sub-Saharan Africa between 2000 and 2014. Investments in malaria programmes can not only reduce malaria morbidity and mortality, thereby contributing to the health targets of the Sustainable Development Goals, but they can also transform the well-being and livelihood of some of the poorest communities across the globe.

RESUMEN

BACKGROUND: The present paper reports on studies that evaluated artesunate + sulfadoxine-pyrimethamine (AS + SP) which is the first-line drug and artemether-lumefantrine (AL) which is a second-line drug against uncomplicated falciparum malaria in Sudan. This evaluation was performed in twenty studies covering six sentinel sites during five successive annual malaria transmission seasons from 2010 to 2015. METHODS: The standard World Health Organization protocol was used for a follow-up period of 28 days. The frequency distribution of molecular markers for antifolate resistance in dihydrofolate reductase (dhfr) and dihydropteroate synthase (dhps) genes was studied in pre-treatment samples in four sites in 2011. RESULTS: In the nine studies of AL conducted at five sites (n = 595), high PCR-corrected cure rates were found, ranging from 96.8 to 100 %. Among the eleven studies of AS + SP (n = 1013), a decline in the PCR-corrected cure rates was observed in Gedaref in Eastern Sudan: 91.0 % in the 2011-12 season and 86.5 % in the 2014-15 season. In the remaining sites, the AS + SP cure rates ranged between 95.6 and 100 %. The rate of clearance of microscopic gametocytaemia after treatment was not significantly different with AL or AS + SP on days 7, 14, 21 and 28 of follow-up. A total of 371 pre-treatment samples were analysed for molecular markers of SP resistance. The temporal changes and geographical differences in the frequency distribution of SP-resistance genotypes showed evidence of regional differentiation and selection of resistant strains. CONCLUSION: The findings of this study call for a need to review the Sudan malaria treatment policy. Epidemiological factors could play a major role in the emergence of drug-resistant malaria in eastern Sudan.

RESUMEN

BACKGROUND: Artesunate + sulfadoxine-pyrimethamine (AS + SP) has been the first-line treatment and artemether-lumefantrine (AL) the second-line treatment for uncomplicated falciparum malaria in Yemen since 2005. This paper reports the results of studies conducted to monitor therapeutic efficacy of these two drugs in sentinel sites in Yemen. METHODS: Eight therapeutic efficacy studies were conducted in six sentinel sites during the period 2009-2013 in Yemen. Five studies were for the evaluation of AS + SP (total of 465 patients) and three studies (total of 268 patients) for the evaluation of AL. The studies were done according to standard WHO protocol 2009 with 28-day follow-up. RESULTS: In the evaluation of AS + SP, the PCR-corrected cure rate was 98 % (95 % CI 92.2-99.5 %) in one site and 100 % in all of the other four sites. In the sites where AL was evaluated, the PCR-corrected cure rate was 100 % in all the sites. All patients were negative for asexual parasitaemia on day 3 in both the AS + SP and the AL groups. There was a higher rate of clearance of gametocytaemia in the AL-treated group when compared with the AS + SP groups from day 7 onwards. CONCLUSION: AS + SP remains the effective drug for uncomplicated falciparum malaria in Yemen. AL is also highly effective and can be an appropriate alternative to AS + SP for the treatment of falciparum malaria. AL demonstrated a higher efficacy in clearing microscopic gametocytaemia than AS + SP. TRIAL REGISTRATION: Trial registration number ACTRN12610000696099.

RESUMEN

OBJECTIVE: Artesunate plus sulfadoxine-pyrimethamine (AS + SP) has been Somalia's national treatment policy since 2006. Routine monitoring of first-line malaria treatment is needed to ensure appropriate national malaria treatment policy and early detection of drug resistance. For this purpose, we conducted therapeutic efficacy studies of AS + SP for the treatment of uncomplicated malaria in Somalia in 2011. METHODS: Studies were conducted in three sentinel sites. Eligible patients were evaluated for clinical and parasitological outcomes according to the WHO standard protocol. Molecular surveillance was conducted on resistance conferring mutations in the P.falciparum dihydrofolate reductase (dfhr) and dihydropteroate synthase (dhps) genes. RESULTS: The proportion of PCR-corrected treatment failures was high in Jamame (22%, 95% CI: 13.7-32.8%) and low (<5%) in Janale and Jowhar. All patients cleared parasites by day 3. Molecular markers associated with SP resistance were detected in all three sites. Treatment failure was associated with the presence of the double mutant dhps A437G/K540E (OR = 22.4, 95% CI: 5.1-98.1), quadruple mutant dhfr N51I/S108N+dhps A437G/K540E (OR = 5.5, 95% CI: 2.3-13.6), quintuple mutant dhfr N51I/C59R/S108N+dhps A437G/K540E (OR = 3.5, 95% CI: 1.4-8.8) and younger age (OR=0.86, 95% CI: 0.76-0.96). CONCLUSIONS: The high treatment failure rate observed in Jamame, together with the presence of molecular mutations associated with SP resistance, indicates P. falciparum resistance to SP. In Jowhar, high treatment failure rates were absent despite the presence of molecular mutations; signs of resistance in vivo may have been masked by the stronger immunity of the older study population. The study underscores the need to update Somalia's national malaria treatment policy.

RESUMEN

We describe here the results of antimalarial therapeutic efficacy studies conducted in Cambodia from 2008 to 2010. A total of 15 studies in four sentinel sites were conducted using dihydroartemisinin-piperaquine (DP) for the treatment of Plasmodium falciparum infection and chloroquine (CQ) and DP for the treatment of P. vivax infection. All studies were performed according to the standard World Health Organization protocol for the assessment of antimalarial treatment efficacy. Among the studies of DP for the treatment of P. falciparum, an increase in treatment failure was observed in the western provinces. In 2010, the PCR-corrected treatment failure rates for DP on day 42 were 25% (95% confidence interval [CI] = 10 to 51%) in Pailin and 10.7% (95% CI = 4 to 23%) in Pursat, while the therapeutic efficacy of DP remained high (100%) in Ratanakiri and Preah Vihear provinces, located in northern and eastern Cambodia. For the studies of P. vivax, the day 28 uncorrected treatment failure rate among patients treated with CQ ranged from 4.4 to 17.4%; DP remained 100% effective in all sites. Further study is required to investigate suspected P. falciparum resistance to piperaquine in western Cambodia; the results of in vitro and molecular studies were not found to support the therapeutic efficacy findings. The emergence of artemisinin resistance in this region has likely put additional pressure on piperaquine. Although DP appears to be an appropriate new first-line treatment for P. vivax in Cambodia, alternative treatments are urgently needed for P. falciparum-infected patients in western Cambodia.

RESUMEN

BACKGROUND: Malaria remains a major public health problem in Togo. The national malaria control programme in Togo changed the anti-malarial treatment policy from monotherapy to artemisinin combination therapy in 2004. This study reports the results of therapeutic efficacy studies conducted on artemether-lumefantrine and artesunate-amodiaquine for the treatment of uncomplicated Plasmodium falciparum malaria in Togo, between 2005 and 2009. METHODS: Children between 6 and 59 months of age, who were symptomatically infected with P. falciparum, were treated with either artemether-lumefantrine or artesunate-amodiaquine. The primary end-point was the 28-day cure rate, PCR-corrected for reinfection and recrudescence. Studies were conducted according to the standardized WHO protocol for the assessment of the efficacy of anti-malarial treatment. Differences between categorical data were compared using the chi-square test or the Fisher's exact test where cell counts were ≤ 5. Differences in continuous data were compared using a t-test. RESULTS: A total of 16 studies were conducted in five sentinel sites, with 459, 505 and 332 children included in 2005, 2007 and 2009, respectively. The PCR-corrected 28-day cure rates using the per-protocol analysis were between 96%-100% for artemether-lumefantrine and 94%-100% for artesunate-amodiaquine. CONCLUSIONS: Both formulations of artemisinin-based combination therapy were effective over time and no severe adverse events related to the treatment were reported during the studies.
