Nutritional risk is a clinical predictor of postoperative mortality and morbidity in surgery for colorectal cancer

This study investigated whether nutritional risk scores applied at hospital admission predict mortality and complications after colorectal cancer surgery.

Neck treatment and shoulder morbidity: Still a challenge

Shoulder complaints and functional impairment are common sequelae of neck dissection. This is often attributed to injury of the spinal accessory nerve by dissection or direct trauma. Nevertheless, shoulder morbidity may also occur in cases in which the spinal accessory nerve has been preserved. In this article, the physiology and pathophysiology of the shoulder are discussed, followed by a consideration of the impact of neck dissection on shoulder complaints, functional impairment, and quality of life. Finally, rehabilitation will be considered. © 2010 Wiley Periodicals, Inc. Head Neck, 2010.

Mortality and morbidity in the city of Bern, Switzerland, 1805-1815 with special emphasis on infant, child and maternal deaths

This article contributes to the research on demographics and public health of urban populations of preindustrial Europe. The key source is a burial register that contains information on the deceased, such as age and sex, residence and cause of death. This register is one of the earliest compilations of data sets of individuals with this high degree of completeness and consistency. Critical assessment of the register's origin, formation and upkeep promises high validity and reliability. Between 1805 and 1815, 4,390 deceased inhabitants were registered. Information concerning these individuals provides the basis for this study. Life tables of Bern's population were created using different models. The causes of death were classified and their frequency calculated. Furthermore, the susceptibility of age groups to certain causes of death was established. Special attention was given to causes of death and mortality of newborns, infants and birth-giving women. In comparison to other cities and regions in Central Europe, Bern's mortality structure shows low rates for infants (q0=0.144) and children (q1-4=0.068). This could have simply indicated better living conditions. Life expectancy at birth was 43 years. Mortality was high in winter and spring, and decreased in summer to a low level with a short rise in August. The study of the causes of death was inhibited by difficulties in translating early 19th century nomenclature into the modern medical system. Nonetheless, death from metabolic disorders, illnesses of the respiratory system, and debilitation were the most prominent causes in Bern. Apparently, the worst killer of infants up to 12 months was the "gichteren", an obsolete German term for lethal spasmodic convulsions. The exact modern identification of this disease remains unclear. Possibilities such as infant tetanus or infant epilepsy are discussed. The maternal death rate of 0.72% is comparable with values calculated from contemporaneous sources. Relevance of childbed fever in the early 1800s was low. Bern's data indicate that the extent of deaths related to childbirth in this period is overrated. This research has an explicit interdisciplinary value for various fields including both the humanities and natural sciences, since information reported here represents the complete age and sex structure of a deceased population. Physical anthropologists can use these data as a true reference group for their palaeodemographic studies of preindustrial Central Europe of the late 18th and early 19th century. It is a call to both historians and anthropologists to use our resources to a better effect through combination of methods and exchange of knowledge.

Morbidity and aging in HIV-infected persons: the Swiss HIV cohort study

Patterns of morbidity and mortality among human immunodeficiency virus (HIV)-infected individuals taking antiretroviral therapy are changing as a result of immune reconstitution and improved survival. We studied the influence of aging on the epidemiology of non-AIDS diseases in the Swiss HIV Cohort Study.

Prefrailty and chronic morbidity in the youngest old: an insight from the Lausanne cohort Lc65+

To estimate the prevalence of prefrailty, frailty, comorbidity, and disability in the youngest old and to identify chronic diseases associated with individual frailty criteria.

Morbidity in surgery: impact of the 50-hour work-week limitation in Switzerland

Work-hour regulations for residency programmes in Switzerland, including a 50-hour weekly limit, were set in on 1 January 2005. Patient safety was one of the major arguments for the implementation. As the effect of the restriction of residency work hours on patient care in Switzerland has not yet been evaluated on objective data, the aim of the present study was to assess its impact by comparing the patients' morbidity and mortality before (2001-2004) and after (2005-2008) the implementation.

Morbidity rate of reoperation in thyroid surgery: a different point of view

Goitre recurrence is a common problem following subtotal thyroid gland resection for multinodular goitre disease. The aim of the present study was to evaluate morbidity rate in relation to the side of initial and redo-surgery for recurrent disease.

Impact of surgical technique on operative morbidity and its socioeconomic benefit in thyroid surgery

The aim of this retrospective cohort study was to evaluate the rate of complications in relation to the extent of surgery and some of its consequences.

Morbidity in 201 patients with small sized meningioma treated by microsurgery

The management of patients with small, often asymptomatic meningiomas is controversial and includes observation, microsurgery (MS) and stereotactic radiosurgery (SRS). The purpose of this retrospective study was to analyze the morbidity and the extent of removal after MS for small (< or =3 cm) intracranial meningiomas and compare these results to those of SRS reported in the literature.

Impact of left ventricular hypertrophy late after aortic valve replacement for aortic stenosis on cardiovascular morbidity and mortality

AIMS: The goal of this study was to assess the prevalence of left ventricular (LV) hypertrophy in patients with aortic stenosis late (>6 months) after aortic valve replacement and its impact on cardiac-related morbidity and mortality. METHODS AND RESULTS: In a single tertiary centre, echocardiographic data of LV muscle mass were collected. Detailed information of medical history and angiographic data were gathered. Ninety-nine of 213 patients (46%) had LV hypertrophy late (mean 5.8 +/- 5.4 years) after aortic valve replacement. LV hypertrophy was associated with impaired exercise capacity, higher New York Heart Association dyspnoea class, a tendency for more frequent chest pain expressed as higher Canadian Cardiovascular Society class, and more rehospitalizations. 24% of patients with normal LV mass vs. 39% of patients with LV hypertrophy reported cardiac-related morbidity (p = 0.04). In a multivariate logistic regression model, LV hypertrophy was an independent predictor of cardiac-related morbidity (odds ratio 2.31, 95% CI 1.08 to 5.41), after correction for gender, baseline ejection fraction, and coronary artery disease and its risk factors. Thirty seven deaths occurred during a total of 1959 patient years of follow-up (mean follow-up 9.6 years). Age at aortic valve replacement (hazard ratio 1.85, 95% CI 1.39 to 2.47, for every 5 years increase in age), coexisting coronary artery disease at the time of surgery (hazard ratio 3.36, 95% CI 1.31 to 8.62), and smoking (hazard ratio 4.82, 95% CI 1.72 to 13.45) were independent predictors of overall mortality late after surgery, but not LV hypertrophy. CONCLUSIONS: In patients with aortic valve replacement for isolated aortic stenosis, LV hypertrophy late after surgery is associated with increased morbidity.

Important excess morbidity due to upper airway anomalies in the perioperative course in infant cardiac surgery

BACKGROUND: The study aimed at defining the excess morbidity or mortality caused by an additional airway malformation in children with congenital heart disease requiring surgery. METHODS: All patients requiring surgery for heart disease during an 8-year period ending in 2003 who had an associated upper airway malformation were retrospectively studied. All patients were seen in 2004 for a prospective follow-up examination. RESULTS: Eleven patients with upper airway anomalies were identified (tracheobronchial malacia in 6 patients, long-segment tracheal stenosis in 3, and bilateral vocal cord paralysis and tracheal hemangioma in 1 patient each). They accounted for 1.5% of the entire cardiac surgical load of 764 patients. In 5 infants, the airway anomaly was diagnosed before cardiac repair, in 6 patients thereafter. Diagnosis was made by bronchoscopy in all patients, by additional bronchography in 2. Failure of rapid postoperative extubation was the most common finding. Airway management was surgical in 2 and conservative in 8 patients, 1 newborn having been denied therapy because of the severity of airway hypoplasia. Compared with patients with isolated cardiac disease, those with additional airway anomalies had significantly longer duration of postoperative mechanical ventilation (median, 24 days versus 3), perioperative hospitalization (median, 72 days versus 11) and total number of days of hospitalization during the first year of life (median, 104 days versus 14). After a maximum follow-up of 8 years (median, 37 months) only 3 of 10 surviving patients remained symptomatic owing to the airway malformation. CONCLUSIONS: Upper airway anomalies accompanying heart disease in infancy resulted in a significant prolongation of perioperative intensive care and hospital stay, as well as duration of mechanical ventilation. Failure of early postoperative extubation was the leading symptom.

Personal mastery attenuates the effect of caregiving stress on psychiatric morbidity

This study examined the protective effects of personal mastery on the relations between both objective and subjective stress and psychiatric morbidity in 79 spousal Alzheimer caregivers. Results indicated that with low mastery, the relations between patient problem behaviors and caregiver psychiatric symptoms was significant (t[71] = 2.03; p = 0.046). However, with high mastery, no significant association was found (t[71] = -0.76; p = 0.452). Similarly, the relations between role overload and psychiatric morbidity was significant when mastery was low (t[71] = 2.22; p = 0.029), but not high (t[71] = -1.49; p = 0.140). These results suggest that caregivers with a greater sense of personal mastery may be protected from the negative effects of caregiver stress.
