IL-6 and TNF-α salivary levels according to the periodontal status in Portuguese pregnant women.

BACKGROUND: Periodontitis is associated with increased concentration of inflammatory markers and saliva has been proposed as a non-invasive diagnostic fluid in oral and systemic diseases. The levels of salivary biomarkers, such as cytokines, could potentially be used to distinguish periodontal healthy individuals from subjects with periodontal disease. The purpose of this study was to characterize the salivary levels of two inflammatory biomarkers associated with periodontitis, interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α), in order to assess whether these cytokines salivary levels could potentially be used to complement periodontitis pregnant women diagnose. METHODS: Forty-four pregnant women were distributed into three groups, according to their periodontal status: healthy, mild/moderate periodontitis and severe periodontitis. Unstimulated saliva was collected and analysis of TNF-α and IL-6 salivary levels were performed with Immulite®. RESULTS: Women with periodontitis exhibited significantly higher levels (p = 0.001) of salivary IL-6 and TNF-α compared with the healthy group: 25.1 (±11.2) pg/mL vs. 16.3 (±5.0) pg/mL and 29.7 (±17.2) pg/mL vs. 16.2 (±7.6) pg/mL, approximately 1.5 and 1.8 times more, respectively. Additionally, cytokines were significantly increased (p < 0.05) in severe periodontitis compared to periodontal healthy pregnant women. CONCLUSIONS: These results revealed that IL-6 and TNF-α salivary biomarkers provide high discriminatory capacity for distinguishing periodontal disease from periodontal health in pregnant women.

Farmer and Veterinarian Attitudes towards the Bovine Tuberculosis Eradication Programme in Spain: What Is Going on in the Field?

The effectiveness of health interventions against bovine tuberculosis (bTB) is influenced by several "non-biological" factors that may hamper bTB detection and control. Although the engagement of stakeholders is a key factor for the eradication programme's success, social factors have been often ignored in the control programmes of animal diseases, especially in developed countries. In this study, we used a qualitative approach to investigate perceptions, opinions, attitudes, and beliefs of farmers, and veterinarians who may influence the effectiveness of the Spanish bTB eradication programme. The study was carried out in two phases. First, 13 key representatives of different groups involved in the programme were interviewed through exploratory interviews to identify most relevant themes circulating in the population. Interviews focused on strong and weak points of the programme; reasons for failure to achieve eradication; benefits of being disease free; future perspectives, and proposed changes to the programme. Based on these results, a thematic guide was developed and detailed information was gained through face-to-face in-depth interviews conducted on a purposive sample of 39 farmers and veterinarians. Data were analysed following an ethnographic methodology. Main results suggested that the bTB programme is perceived as a law enforcement duty without an adequate motivation of some stakeholders and a general feeling of distrust arose. The complexity of bTB epidemiology combined with gaps in knowledge and weak communication throughout stakeholders contributed to causing disbeliefs, which in turn generated different kinds of guesses and interpretations. Low reliability in the routine skin test for bTB screening was expressed and the level of confidence on test results interpretation was linked with skills and experience of public and private veterinarians in the field. Lack of training for farmers and pressure faced by veterinarians during field activities also emerged. Few benefits of being bTB free were perceived and comparative grievances referred to wildlife and other domestic reservoirs, sector-specific legislation for bullfighting farms, and the absence of specific health legislation for game hunting farms were reported. Understanding reasons for demotivation and scepticism may help institutions to ensure stakeholders' collaboration and increase the acceptability of control measures leading to an earlier achievement of eradication.

Bowel complications of deep endometriosis during pregnancy or in vitro fertilization.

OBJECTIVE: To review bowel complications caused by deep endometriosis during pregnancy or in vitro fertilization (IVF). DESIGN: Three case reports and a systematic review. SETTING: A tertiary referral center for deep endometriosis surgery. PATIENT(S): Three case reports of bowel perforation or occlusion during pregnancy caused by deep endometriosis. INTERVENTION(S): A PubMed search was conducted to identify complications of deep endometriosis during pregnancy or IVF. The literature search identified 13 articles. According to these, 12 articles described 12 bowel complications caused by progression of deep endometriosis during pregnancy, and 1 article described six cases of bowel occlusion during IVF. RESULT(S): In 12 of 15 women, complications occurred during the third trimester of pregnancy, whereas 3 of 15 women presented with complications in the postpartum period. All complications during IVF occurred during stimulation. No specific factors that could predict these complications were identified, leading to the conclusion that endometriosis complications that occur in pregnancy or in IVF patients are probably underreported. CONCLUSION(S): Bowel complications during pregnancy or IVF stimulation may occur in women with deep endometriosis. This suggests that the endocrine environment of pregnancy does not prevent progression, at least in some women. These complications are rare, although probably underreported.

The source of error in the estimation of intertwin birth weight discordance.

OBJECTIVE: to assess the accuracy of paired estimated fetal weights (EFWs) to predict three levels of twin birth weight discordance (>15%, >20% and >25%). METHOD: a cohort of twin pairs underwent ultrasound examinations within 2 weeks from birth. We calculated the frequency of under- and overestimation of the actual birth weight (< or >10%, respectively) in the entire cohort as well in the subset of mono- and dichorionic pairs. RESULTS: discordance was largely underestimated (observed 10.4 ± 0.8% compared to actual 19.2 ± 1.1%, P=0.001) because the larger twin was more frequently underestimated [30.6 vs. 17.7%, odds ratio (OR) 2.0, 95% confidence interval (CI) 1.1, 3.9 in the entire cohort, and 34.2 vs. 13.1%, OR 3.4, 95% CI 1.4, 8.4 in the dichorionic pairs]. Overall, the specificity for detecting the three levels of discordance was adequate (91.5-94.2%) but the sensitivity was poor (11.1-17.8%) and tended to decrease with increasing discordance level. CONCLUSION: the poor ability of paired EFWs to diagnose birth weight discordance results from underestimation of the larger twin.

Desfecho da gravidez nas jovens adolescentes / Teenage pregnancy outcome

OBJETIVO: comparar parto e seguimento de gravidez entre grávidas adolescentes e não-adolescentes que pariram num hospital terciário da região de Lisboa (Portugal). MÉTODOS: estudo retrospectivo com 10.656 partos. Foram avaliados: seguimento da gravidez, idade gestacional no parto, tipo de parto, necessidade de episiotomia e lacerações graves, índice de Apgar no quinto minuto e peso ao nascer. As grávidas foram divididas em dois grupos, acima e abaixo dos 20 anos. O grupo abaixo dos 20 anos foi depois subdividido entre grávidas com menos ou mais de 16 anos. Foi usado o teste do χ2 para análise estatística. RESULTADOS: as adolescentes tiveram pior seguimento: primeira consulta após as 12 semanas (46,4 versus 26,3 por cento) e menos de quatro consultas (8,1 versus 3,1 por cento), menos distocia (21,5 versus 35,1 por cento), menos cesarianas (10,6 versus 20,7 por cento) e menor necessidade de indução do trabalho de parto (16,5 versus 26,5 por cento). Não houve diferença significativa para idade gestacional no parto e taxa de recém-nascidos de baixo peso. Entre adolescentes, as menores de 16 anos tiveram mais recém-nascidos de baixo peso (12 versus 7,4 por cento) e mais partos entre 34 e 37 semanas (10,8 versus 4,2 por cento). CONCLUSÕES: num hospital com serviço dedicado a grávidas adolescentes com apoio social e psicológico, apesar de pior seguimento pré-natal vigilância, o seu desempenho não foi pior. Uma atenção especial deve, no entanto, ser dada a grávidas abaixo dos 16 anos.

PURPOSE: to compare delivery and pregnancy follow-up among adolescent and non-adolescent pregnant women whose delivery occurred in a tertiary hospital from Região de Lisboa (Portugal). METHODS: retrospective study with 10,656 deliveries. Pregnancy follow-up, delivery type, need of episiotomy and severe lacerations, Apgar index at the fifth minute and the delivery weight have been evaluated. The pregnant women were divided into two groups, over and under 20 years old. The group with women under 20 was further subdivided in pregnant women under or over 16. The χ2 test has been used for statistical analysis. RESULTS: adolescents presented worse follow-up: first appointment after 12 weeks (46.4 versus 26.3 percent) and less than four appointments (8.1 versus 3.1 percent), less dystocia (21.5 versus 35.1 percent), less caesarian sections (10.6 versus 20.7 percent), and lower need for inducing labor (16.5 versus 26.5 percent). There was no significant difference concerning gestational age at delivery and ratio of low weight newborns. Among adolescents, the ones under 16 had more low weight newborns (12 versus 7.4 percent) and more deliveries between 34 and 37 weeks (10.8 versus 4.2 percent). CONCLUSIONS: in a hospital attending adolescents with social and psychological support, the fact of them having had a worse follow-up in the pre-natal phase, their performance has not been worse. Nevertheless, special attention might be given to pregnant women under 16.

[Peripartum cardiomyopathy]. / Miocardiopatia periparto.

The Peripartum Cardiomyopathy is a rare form of heart disease, of uncertain etiology, more common in black and multiparous women, older than thirty years old. Is defined as development of maternal congestive heart failure, in the last month of pregnancy or within five months after delivery, with documented left ventricular systolic dysfunction, in the absence of a demonstrable cause for heart failure in a previously healthy woman. The diagnosis is commonly established with chest radiography, electrocardiogram and echocardiography. Treatment consist in medical therapy with inotropic support, afterload and preload redution, and anticoagulation. Surgical care with cardiac transplantation is indicated in severe cases with progressive left ventricular dysfunction, despite medical therapy. Prognosis seems dependent on recovery of left ventricular function and maternal mortality rates could reach 50%. Future pregnancy is not recommended in woman with persistent ventricular dysfunction. The authors present a case report in a black nuliparous woman at term, with 33 years old, without previous heart disease that presents a sudden heart failure, with ventricular dysfunction on echocardiography, after the caesarean, with recovery of normal ventricular function at 11th day of puerperium.
