RESUMEN

BACKGROUND: Rifampicin (RIF) is considered the backbone of TB treatment, but adverse effects often limit its use. METHODS: This retrospective cohort study examined patients treated for TB disease at our institution, and compared those who received RIF to those who were intolerant to RIF. RESULTS: A total of 829 patients were included. Seventy-six patients (9%) were intolerant to RIF. Patients with RIF intolerance were significantly older (median age: 67 years, IQR 50-78 vs. 48 years, IQR 31-70; P < 0.0001), and were more likely to be female (57% vs. 41%; P = 0.01) and have concurrent diabetes mellitus (37.3% vs. 19%; P < 0.0001) compared to those who tolerated RIF. RIF intolerance was most commonly due to transaminitis (25%), cytopenia (14.5%), rash (17.1%) and gastro-intestinal intolerance (7.8%). Twenty patients were subsequently challenged with rifabutin, and this was successful in 70%. The mean treatment duration was significantly longer in patients who were intolerant to RIF (335 vs. 270 days; P < 0.001). There was no significant difference in treatment outcomes. CONCLUSION: RIF intolerance is more common in older patients, females, and those with concurrent diabetes mellitus. Patients who could not tolerate RIF had a longer duration of therapy, but no difference in treatment outcomes. When attempted, rifabutin was well tolerated in most patients with a previous RIF-related adverse event.

CONTEXTE: La rifampicine (RIF) est généralement considérée comme le pilier du traitement de la TB, cependant, ses effets indésirables limitent fréquemment son utilisation. MÉTHODES: Dans cette étude de cohorte rétrospective nous avons examiné les patients traités pour la TB dans notre institution et avons comparé ceux qui ont reçu la RIF à ceux qui n'ont pas pu la tolérer. RÉSULTATS: Au total, 829 patients ont été inclus. Soixante-seize patients (9%) étaient intolérants au RIF. Les patients intolérants au RIF étaient significativement plus âgés (âge médian : 67 ans, IQR 50­78 vs. 48 ans, IQR 31­70 ; P < 0,0001), et étaient plus susceptibles d'être des femmes (57% vs. 41% ; P = 0,01) et d'avoir un diabète sucré concomitant (37,3% vs. 19% ; P < 0,0001) par rapport à ceux qui toléraient le RIF. L'intolérance au RIF était principalement due à une transaminite (25%), une cytopénie (14,5%), une éruption cutanée (17,1%) et une intolérance gastro-intestinale (7,8%). Vingt patients ont ensuite été soumis à un test de provocation à la rifabutine, avec un taux de succès de 70%. La durée moyenne du traitement était significativement plus longue chez les patients intolérants au RIF (335 vs. 270 jours ; P < 0.001). Aucune différence significative n'a été observée dans les résultats du traitement. CONCLUSION: L'intolérance au RIF est plus courante chez les patients plus âgés, les femmes et les patients atteints de diabète sucré. Les patients qui n'ont pas pu tolérer le RIF ont suivi un traitement plus long, mais cela n'a pas entrainé de différence dans les résultats du traitement. Lorsqu'elle a été tentée, la rifabutine a été bien tolérée par la plupart des patients ayant déjà présenté un effet indésirable lié au RIF.

RESUMEN

Introduction: Post-partum depression can have adverse long term effects. For the mother, the episode can be the precursor of chronic recurrent depression. For her children her on going depression can contribute to emotional, cognitive and interpersonal problems in their later life. In the present study, we aimed to identify the incidence of depression in post-partum period and explore the underlying etiological factors responsible for the same. Materials and Methods: A cross sectional study was conducted on 250 post- natal mothers covered under UHTC, Tripuri, Patiala. The data collection was done through one to one interview technique with mental evaluation done by Edinburgh Postnatal Depression Scale instrument. Based upon the results, the cases were classified either as normal or presence of psychiatric morbidity. Psychiatry referral was provided to those requiring it. Association of post-partum depression with various socio-demographic and medical correlates was then sought through statistical analysis. Results: Post-partum depression was observed in 82 out of 250 females (32.8%). On univariable analysis family income, illiteracy, history of depression, caesarean section, death in family, were significantly associated with post-partum depression. On multi-variable analysis, poverty, female gender of baby, domestic violence and were observed as true predictors of depression in post-partum period (p<0.05). Conclusion: Depression was prevalent among almost one-third of postnatal females. Poverty, Cesarean section, domestic violence and poor spousal support have been identified as major contributors towards psychiatric morbidities. Taking care of these largely modifiable risk factors can prevent development of postpartum depression.

RESUMEN

The importance and variability of pre-operative anaemia in cardiac surgical patients across the UK is not known, and there is debate about its association with patient outcomes. The Association of Cardiothoracic Anaesthetists carried out its first national audit on anaemia and transfusion, and analysed data from 19,033 patients operated on in 12 cardiac surgical centres between 2010 and 2012; 5895 (31%) had pre-operative anaemia. Centre-specific prevalence of anaemia varied from 23% to 45%; anaemia was associated with older patients, diabetes and surgical risk (EuroSCORE). Nevertheless, controlling for these factors, regional variation remained an independent effect (p < 0.001). Multivariable analysis demonstrated an independent association of anaemia with transfusion (odds ratio (95% confidence interval) 2.75 (2.55-2.95), p < 0.001), mortality (1.42 (1.18-1.71), p < 0.001) and hospital stay (geometric mean ratio (95% confidence interval) 1.15 (1.13-1.17), p < 0.001). Haemoglobin concentration per se was also independently associated with worse outcomes; a 10 g.l(-1) decrease in haemoglobin was associated with a 43% increase (95% confidence interval 40-46%) in the odds of transfusion and a 16% increase (95% confidence interval 10-22%) in the odds of mortality (both p < 0.001). This large UK-wide audit has demonstrated marked regional variation in both anaemia and transfusion, with a consistently high incidence of both. The independent association between pre-operative anaemia and worse outcomes in UK practice has also been confirmed, and robust prospective study of anaemia treatment before cardiac surgery is required; these data will assist in designing such trials.

RESUMEN

Porcine reproductive and respiratory syndrome (PRRS) is a swine disease of major economic importance that causes reproductive and respiratory problems in pigs. PRRSV strains are divided into European (Type 1) and North-American (Type 2) genotypes. Within the European PRRSV genotype, three subtypes have been delineated. Full genome sequences for North American and European subtype 1 strains have been described. Here, the first complete genomic characterization of a European subtype 3 strain (Lena) is described. Amplification of Orf1a and Orf1b fragments was achieved using a set of degenerate oligonucleotides. Using RT-PCR with Lena-specific primers, the full length sequence (15001 nt) was obtained. Alignment of Lena with European subtype 1 reference strain Lelystad showed variation over the entire length (84% identity/89% similarity at amino acid level) with the most variation in Orf1a (Nsp2/NSP2) with a deletion of 29 amino acids. Phylogenetic relationships using different Orfs supported Lena's genetic distinction from European subtype 1 strains. The availability of the European subtype 3 PRRSV full genome may be important for the understanding of PRRSV evolution and the more pronounced pathogenic nature of Lena.
