Low back pain among Italian runners: A cross-sectional survey.

BACKGROUND: Low Back Pain (LBP) is commonly reported as a very frequent disorder in sports, but its prevalence in runners remains unclear. OBJECTIVES: To determine the prevalence of LBP in a wide sample of Italian runners. DESIGN: A cross-sectional online survey. SETTING: A national survey, according to the CHERRIES and STROBE guidelines, was performed in 2019. PARTICIPANTS: 2539 Italian runners. METHODS: A sample of Italian runners registered with national running associations was recruited. The survey was conducted using an online survey development platform. The questionnaire was self-reported and included 38 questions. MAIN OUTCOME MEASURES: Descriptive statistics and frequencies were used to analyze results. Relationships between demographics, daily habits and running characteristics and the responses given was calculated with Cramer's V. Only correlation values higher >0.60 were deemed of interest. RESULTS: 2539 questionnaires (63.5%) were valid for analysis. In total, 22.6% of runners reported having experienced LBP in the past year. Most participants (77.0%) reporting episodes of LBP believed it was not caused by running. No significant correlations (Cramer's V < 0.60) were found between LBP and demographics, training characteristics or lifestyle habits. CONCLUSION: The prevalence of LBP among Italian runners was 22,57%. LBP was not associated with training, equipment or lifestyle.

Low back pain among Italian rowers: A cross-sectional survey.

BACKGROUND: Low Back Pain is commonly reported to be a very frequent disorder in rowing, but it is still unclear if its prevalence is higher than in other sports or even in a non-athletes group. OBJECTIVES: To determine prevalence of low back pain (LBP) with and without irradiated pain and possibly related risk factors in a group of elite Italian rowers. METHODS: The study was conducted during the 2010 Italian Indoor Rowing Championship held in Bari from 30th to 31st January. All the 415 rowers who qualified for the national championship were asked to complete a three-page questionnaire on LBP, assisted by a physiotherapist. RESULTS: One hundred and thirty-three athletes (32%) completed the assessment. LBP was very common, with a lifetime and 1 year prevalence of 64.7% and 40.6% respectively. During the last episode, the LBP intensity, measured by a numeric rating scale (NRS), presented a median value of 6/10, and 40% of rowers reported some limitation in daily living activities (ADL). Odds ratio (OR) to suffer from LBP was 2.62 in males compared to females; athletes who row both in sculling and sweep or only sweep showed an OR of 4.43 and 3.32 respectively. CONCLUSIONS: The prevalence of low back pain among rowers seems to be comparable to the one of the general population, even if the recovery appears to be faster. The risk of developing LBP is associated with the rowing typology and the gender, but a prospective study with an adequate sample size is necessary to clearly identify risk factors for LBP in rowers and to implement effective prevention strategies.

Triggering receptor expressed on myeloid cells: role in the diagnosis of lung infections.

The triggering receptor expressed on myeloid cells (TREM)-1 is a recently described molecule, which plays an important role in myeloid cell-activated inflammatory responses. TREM-1 is expressed on blood neutrophils and monocytes, and also on alveolar macrophages, thus suggesting a potential role in lung inflammatory responses against infections. To investigate the differential expression of TREM-1 in lung infections, its levels were assessed in bronchoalveolar lavage specimens from patients with community-acquired pneumonia or tuberculosis. TREM-1 was also investigated in patients with interstitial lung diseases, as a model of noninfectious inflammatory disease of the lung. TREM-1 expression was significantly increased in lung neutrophils and in lung macrophages of patients with pneumonia (n=7; 387.9+/-61.4 and 660.5+/-18.3, respectively) compared with patients with pulmonary tuberculosis (n=7; 59.2+/-13.1 and 80.6+/-291.2) and patients with interstitial lung diseases (n=10; 91.8+/-23.3 and 123.9+/-22.8). In contrast, TREM-1 expression on peripheral blood neutrophils was no different among the three groups. In conclusion, these data suggest that triggering receptor expressed on myeloid cells-1 is selectively expressed in the lungs of patients with pneumonia caused by extracellular bacteria and not in patients with tuberculosis, providing a potential marker for differential diagnosis.

Extensäo profilática da ligamentotomia ao membro contralateral nos pacientes hemodialisados afetados por síndrome do túnel do carpo / Prophilactic extension of ligamentotomy of the contralateral member in hemodialysed patients affected by the carpal tunnel syndrome

Dentro do contexto das patologias esqueléticas observadas com frequência no paciente dialisado, a síndrome do túnel do carpo ocupa os primeiros lugares na taxa de incidência. Embora seja relatada com percentagens diversas por vários autores, geralmente a mesma aparece de 5 a 8 anos após a hemodiálise, com um percentual de 50 por cento após 15 anos e de 100 por cento após 20 anos. Os A.A., examinando os dados relevados pela casuística própria e aqueles relatados na literatura, voltaram sua atençäo para a maior incidência das síndromes monolaterais do lado do acesso vascular e para a precocidade do aparecimento das mesmas. Com base nessas premissas, formularam a hipótese da possibilidade de uma intervençäo profilática ou de um rígido follow-up a nível do membro contralateral nos pacientes submetidos a ligamentotomia do membro sede do acesso vascular, visto que a intervençäo eletiva de ligamentotomia, mesmo sendo resolutiva para a sintomatologia álgica, näo permite a recuperaçäo morfo-funcional do nervo mediano
