An outcome and cost analysis of anal fistula plug insertion vs endorectal advancement flap for complex anal fistulae.

AIM: The study aimed to compare the rate of success and cost of anal fistula plug (AFP) insertion and endorectal advancement flap (ERAF) for anal fistula. METHOD: Patients receiving an AFP or ERAF for a complex single fistula tract, defined as involving more than a third of the longitudinal length of of the anal sphincter, were registered in a prospective database. A regression analysis was performed of factors predicting recurrence and contributing to cost. RESULTS: Seventy-one patients (AFP 31, ERAF 40) were analysed. Twelve (39%) recurrences occurred in the AFP and 17 (43%) in the ERAF group (P = 1.00). The median length of stay was 1.23 and 2.0 days (P < 0.001), respectively, and the mean cost of treatment was euro5439 ± euro2629 and euro7957 ± euro5905 (P = 0.021), respectively. On multivariable analysis, postoperative complications, underlying inflammatory bowel disease and fistula recurring after previous treatment were independent predictors of de novo recurrence. It also showed that length of hospital stay ≤ 1 day to be the most significant independent contributor to lower cost (P = 0.023). CONCLUSION: Anal fistula plug and ERAF were equally effective in treating fistula-in-ano, but AFP has a mean cost saving of euro2518 per procedure compared with ERAF. The higher cost for ERAF is due to a longer median length of stay.

Late careers and the transition to retirement in Switzerland

A substantial body of life-course research has considered occupational trajectories in Switzerland focusing either on early or middle adulthood careers. However, the issue of the last working period and the retirement transition is receiving increasing attention for several reasons: the permanence of low birth rates associated with an ageing population, a high proportion of active old workers, continuous changes in the timing of retirements, and active ageing policies aiming at keeping people working after the state pension age. Moving forward on this topic, the present doctoral thesis aimed to offer new insights on the dynamics of the final career phase and the transition to retirement in Switzerland through a life-course approach. Concerning the main results, this thesis provides consistent evidences on the great influence of longterm familial and employment trajectories as well as individual positional factors on (i) the vulnerability during the last working period, (ii) the timing of retirement, (iii) the voluntariness of late retirement, and (iv) the financial well-being of retirees. In this way, this thesis offers significant contributions to the life-course, gender, and social policy research focused on ageing processes. -- Un ensemble considérable de recherches sur les parcours de vie a examiné les trajectoires professionnelles en Suisse, en mettant l'accent sur la carrière professionnelle des jeunes et, plus tard, à l'âge adulte. Toutefois, l'étude de la fin de la carrière professionnelle (c'est-à-dire de 50 ans jusqu'à la retraite) reçoit une attention croissante pour plusieurs raisons: la persistance du faible taux de natalité associé à une population vieillissante, la forte proportion de travailleurs âgés actifs, des évolutions continues dans le moment du départ à la retraite, et des politiques visant à maintenir les personnes âgées au travail après l'âge légal de la retraite. Pour aller de l'avant sur ce sujet, la présente thèse de doctorat vise à offrir de nouvelles perspectives sur la fin de carrière et la transition à la retraite en Suisse, en mobilisant les outils de la sociologie des parcours de vie. En ce qui concerne les principaux résultats, cette thèse fournit des preuves cohérentes sur la grande influence des trajectoires professionnelles et familiales ainsi que des facteurs positionnels sur (i) la vulnérabilité au cours de la période de travail avant la retraite, (ii) le moment de départ à la retraite, (iii) le caractère volontaire de la retraite tardive, et (iv) le bien-être financier des retraités. Ainsi, cette thèse fournit d'importantes contributions à la recherche sur les parcours de vie, sur les étu es genre, et sur les politiques sociales, focalisées sur le processus de vieillissement.

Eligibility to treatment and economic effect of the implementation of the new U.S. or European Society of Hypertension/European Society of Cardiology hypertension guidelines.

OBJECTIVE: To evaluate the population and economic impact of implementing the new Joint National Committee (JNC) or European Society of Hypertension (ESH)/European Society of Cardiology (ESC) hypertension guidelines in the Swiss population. METHODS: Cross-sectional, population-based sample (6708 participants) collected between 2003 and 2006 in the city of Lausanne, Switzerland. Blood pressure categories were defined according to both the JNC (JNC-7 and JNC-8) and the ESH/ESC (2007 and 2013) guidelines. RESULTS: The proportion of participants aged 35-60 years eligible for drug treatment was 25.6% [95% confidence interval (CI) 24.4-26.9%] and 24.8% (95% CI 23.6-26.0%) for the JNC-7 and the JNC-8 guidelines, respectively; for participants aged 60-75 years, the values were 62.3% (95% CI 60.1-64.5%) and 46.8% (95% CI 44.5-49.0%), respectively. Shifting from the JNC-7 to the JNC-8 guidelines would lead to an annual saving of 163.6 million Swiss francs (187.7 million US dollars or 134.5 million European euro). The proportion of participants aged 35-75 years without chronic kidney disease, diabetes mellitus or reported history of cardiovascular disease and eligible for treatment was 30.2% (95% CI 29.0-31.4%) for the ESH/ESC 2007 and 2013 guidelines. For participants with chronic kidney disease, diabetes mellitus or reported history of cardiovascular disease, the values were 73.6% (95% CI 70.8-76.3%) and 55.6% (95% CI 52.5-58.8%), respectively. Shifting from the ESH/ESC 2007 to the ESH/ESC 2013 guidelines would lead to an annual saving of 86.9 million Swiss francs (99.5 million US dollars or 71.4 million European euro). CONCLUSION: In Switzerland, shifting from the JNC-7 to the JNC-8 guidelines or from the ESH/ESC 2007 to the ESH/ESC 2013 guidelines would decrease the prevalence of patients eligible for treatment and increase the percentage of treated patients within blood pressure goals. Both strategies lead to potential savings in antihypertensive drug treatment.

Single Heartstring aortotomy for multiple off-pump venous bypass grafts.

Off-pump coronary bypass grafting may decrease the rate of stroke, due to minimal aortic manipulation. For venous grafts, clampless hemostasis when performing the proximal anastomosis can be achieved using the Heartstring device. We describe a technique using a single device to suture two veins to one aortotomy. This technique requires less space and could be advantageous in very short, small, and calcified aortas. In to our experience, this technique is rapid, simple, easy to reproduce, and cost-saving.

Improving the molecular diagnosis of Chlamydia psittaci and Chlamydia abortus infection with a species-specific duplex real-time PCR.

Chlamydia psittaci and Chlamydia abortus are closely related intracellular bacteria exhibiting different tissue tropism that may cause severe but distinct infection in humans. C. psittaci causes psittacosis, a respiratory zoonotic infection transmitted by birds. C. abortus is an abortigenic agent in small ruminants, which can also colonize the human placenta and lead to foetal death and miscarriage. Infections caused by C. psittaci and C. abortus are underestimated mainly due to diagnosis difficulties resulting from their strict intracellular growth. We developed a duplex real-time PCR to detect and distinguish these two bacteria in clinical samples. The first PCR (PCR1) targeted a sequence of the 16S-23S rRNA operon allowing the detection of both C. psittaci and C. abortus. The second PCR (PCR2) targeted the coding DNA sequence CPSIT_0607 unique to C. psittaci. The two PCRs showed 100 % detection for ≥ 10 DNA copies per reaction (1000 copies ml- 1). Using a set of 120 samples, including bacterial reference strains, clinical specimens and infected cell culture material, we monitored 100 % sensitivity and 100 % specificity for the detection of C. psittaci and C. abortus for PCR1. When PCR1 was positive, PCR2 could discriminate C. psittaci from C. abortus with a positive predictive value of 100 % and a negative predictive value of 88 %. In conclusion, this new duplex PCR represents a low-cost and time-saving method with high-throughput potential, expected to improve the routine diagnosis of psittacosis and pregnancy complication in large-scale screening programs and also during outbreaks.
