An Insight Into Cervical Cancer Screening and Treatment Capacity in Sub Saharan Africa.

OBJECTIVE Approximately 85% of cervical cancer cases and deaths occur in resource-constrained countries where best practices for prevention, particularly for women with HIV infection, still need to be developed. The aim of this study was to assess cervical cancer prevention capacity in select HIV clinics located in resource-constrained countries. MATERIALS AND METHODS A cross-sectional survey of sub-Saharan African sites of 4 National Institutes of Health-funded HIV/AIDS networks was conducted. Sites were surveyed on the availability of cervical cancer screening and treatment among women with HIV infection and without HIV infection. Descriptive statistics and χ or Fisher exact test were used as appropriate. RESULTS Fifty-one (65%) of 78 sites responded. Access to cervical cancer screening was reported by 49 sites (96%). Of these sites, 39 (80%) performed screening on-site. Central African sites were less likely to have screening on-site (p = .02) versus other areas. Visual inspection with acetic acid and Pap testing were the most commonly available on-site screening methods at 31 (79%) and 26 (67%) sites, respectively. High-risk HPV testing was available at 29% of sites with visual inspection with acetic acid and 50% of sites with Pap testing. Cryotherapy and radical hysterectomy were the most commonly available on-site treatment methods for premalignant and malignant lesions at 29 (74%) and 18 (46%) sites, respectively. CONCLUSIONS Despite limited resources, most sites surveyed had the capacity to perform cervical cancer screening and treatment. The existing infrastructure of HIV clinical and research sites may provide the ideal framework for scale-up of cervical cancer prevention in resource-constrained countries with a high burden of cervical dysplasia.

Performance recovery from exercise: A review from a statistical point of view

Background. Research into methods for recovery from fatigue due to exercise is a popular topic among sport medicine, kinesiology and physical therapy. However, both the quantity and quality of studies and a clear solution of recovery are lacking. An analysis of the statistical methods in the existing literature of performance recovery can enhance the quality of research and provide some guidance for future studies. Methods: A literature review was performed using SCOPUS, SPORTDiscus, MEDLINE, CINAHL, Cochrane Library and Science Citation Index Expanded databases to extract the studies related to performance recovery from exercise of human beings. Original studies and their statistical analysis for recovery methods including Active Recovery, Cryotherapy/Contrast Therapy, Massage Therapy, Diet/Ergogenics, and Rehydration were examined. Results: The review produces a Research Design and Statistical Method Analysis Summary. Conclusion: Research design and statistical methods can be improved by using the guideline from the Research Design and Statistical Method Analysis Summary. This summary table lists the potential issues and suggested solutions, such as, sample size calculation, sports specific and research design issues consideration, population and measure markers selection, statistical methods for different analytical requirements, equality of variance and normality of data, post hoc analyses and effect size calculation.^

Crioterapia como tratamento de entorses de tornozelos de atletas: revisão sistemática

A crioterapia é prática comum na medicina esportiva, pela praticidade, facilidade de acesso e baixo custo, possuindo vantajoso uso na Saúde Pública. No entanto, os efeitos analgésicos do gelo tem pouca base objetiva e sistematizada em termos de técnicas, duração e frequência. O objetivo deste estudo foi sintetizar através da revisão sistemática (RS) as evidências relativas à efetividade da crioterapia para o tratamento das entorses de tornozelo de atletas. A RS é um método de pesquisa observacional e retrospectivo, pelo qual se tratam artigos, preferencialmente Ensaios Clínicos Aleatórios – ECA, como sujeitos da investigação, com rigorosos critérios de inclusão e exclusão e, quando possível, realiza-se uma macro estatística dos resultados – metaanálise. No presente RS, foram consultados cinco bancos de dados - Medline, Embase, Cochrane, Lilacs e PEDro para buscar ECA sobre crioterapia com os desfechos dor, edema, rigidez e função. Resultados: 289 estudos foram identificados inicialmente, dos quais nove com tratamentos isolados ou associados à crioterapia, porém apenas um preencheu aos critérios de inclusão, cujo N era 121 atletas, dos quais 64 receberam a crioterapia (funcional) e 57 no grupo controle (imobilização). Maior probabilidade para o evento dor foi observada no grupo controle, após 3 e 12 meses. A RS revelou uma lacuna em ECA dentro do tema, mas não encontrou efeito adverso na prática da crioterapia, sendo um princípio analgésico importante, sobretudo em lesões de tecidos moles.

Diode laser treatment of pre-threshold and threshold retinopathy of prematurity

Purpose: Retinopathy of prematurity (ROP) is a sight-threatening condition of premature infants. This study aimed to investigate the efficacy of diode laser photocoagulation in the treatment of pre-threshold and threshold ROP. Methods: A retrospective review was conducted of patients who underwent diode laser treatment for ROP by one author (GAG) from 1992 to 2000. During this time, 2137 babies

Equine laminitis

This article discusses the physiology of the normal feet of horses, in order to understand the pathogenesis of laminitis. It also discusses the use of cryotherapy to treat horses with laminitis.

Effects of cold water immersion and active recovery on hemodynamics and recovery of muscle strength following resistance exercise

Cold water immersion (CWI) and active recovery (ACT) are frequently used as postexercise recovery strategies. However, the physiological effects of CWI and ACT after resistance exercise are not well characterized. We examined the effects of CWI and ACT on cardiac output (Q̇), muscle oxygenation (SmO2), blood volume (tHb), muscle temperature (Tmuscle), and isometric strength after resistance exercise. On separate days, 10 men performed resistance exercise, followed by 10 min CWI at 10°C or 10 min ACT (low-intensity cycling). Q̇ (7.9 ± 2.7 l) and Tmuscle (2.2 ± 0.8°C) increased, whereas SmO2 (-21.5 ± 8.8%) and tHb (-10.1 ± 7.7 μM) decreased after exercise (P < 0.05). During CWI, Q̇ (-1.1 ± 0.7 l) and Tmuscle (-6.6 ± 5.3°C) decreased, while tHb (121 ± 77 μM) increased (P < 0.05). In the hour after CWI, Q̇ and Tmuscle remained low, while tHb also decreased (P < 0.05). By contrast, during ACT, Q̇ (3.9 ± 2.3 l), Tmuscle (2.2 ± 0.5°C), SmO2 (17.1 ± 5.7%), and tHb (91 ± 66 μM) all increased (P < 0.05). In the hour after ACT, Tmuscle, and tHb remained high (P < 0.05). Peak isometric strength during 10-s maximum voluntary contractions (MVCs) did not change significantly after CWI, whereas it decreased after ACT (-30 to -45 Nm; P < 0.05). Muscle deoxygenation time during MVCs increased after ACT (P < 0.05), but not after CWI. Muscle reoxygenation time after MVCs tended to increase after CWI (P = 0.052). These findings suggest first that hemodynamics and muscle temperature after resistance exercise are dependent on ambient temperature and metabolic demands with skeletal muscle, and second, that recovery of strength after resistance exercise is independent of changes in hemodynamics and muscle temperature.

Efeito da crioterapia na noção de posição articular da articulação do joelho em atletas de futebol

A crioterapia é uma técnica bastante divulgada por médicos fisioterapeutas na área do desporto, esta é uma técnica eficaz na redução do edema da dor,na diminuição de lesões secundárias e na redução do processo inflamatório, mas são questionáveis seus efeitos na noção de posição articular dos atletas. Objetivo: O objetivo deste estudo foi avaliar os efeitos ocorridos na noção de posição articular na articulação do joelho no jogador de futebol nos diferentes níveis , amador, junior e de elite, e avaliar a diferença de resposta entre estes três grupos, relacionada ao tempo de treino. Metodologia: Foram avaliados 31 atletas em três diferentes níveis de atuação, amador, junior e elite, foi efetuada a medida de noção de posição articular do joelho antes e após a aplicação a crioterapia local, durante 15 minutos, no aparelho Isocinetico Biodex 4 . Resultados: Não foram encontrados resultados que sugiram a alteração na noção de posição articular entre grupos, no entanto constamos que o grupo de sujeitos juniores parece melhorar a sua precisão após a aplicação de crioterapia. Conclusão: Na amostra em estudo não encontramos valores que sugiram alteração na noção de posição articular na articulação do joelho após aplicação da crioterapia.
