RESUMO
BACKGROUND: Balancing the number of nursing staff in relation to the number of patients is important for hospitals to remain efficient and optimizing the use of resources. One way to do this is to work with a workload management method. Many workload management methods use a time study to determine how nurses spend their time and to relate this to patient characteristics in order to predict nurse workload. OBJECTIVE: In our study, we aim to determine how nurses spend their working day and we will attempt to explain differences between specialized surgical wards. SETTING: The research took place in an academic hospital in the Netherlands. Six surgical wards were included, capacity 15 to 30 beds. METHOD: We have used a work sampling methodology where trained observers registered activities of nurses and patient details every ten minutes during the day shift for a time period of three weeks. RESULTS: The work sampling showed that nurses spend between 40.1% and 55.8% of their time on direct patient care. In addition to this, nurses spend between 11.0% and 14.1% on collective patient care. In total, between 52.1% and 68% of time spent on tasks is directly patient related. We found significant differences between wards for 10 of the 21 activity groups. We also found that nurses spend on average 31% with the patient (bedside), which is lower than in another study (37%). However, we noticed a difference between departments. For regular surgical departments in our study this was on average 34% and for two departments that have additional responsibilities in training and education of nursing students, this was on average 25%. CONCLUSIONS: We found a relatively low percentage of time spent on direct plus indirect care, and a lower percentage of time spent with the patient. We suspect that this is due to the academic setting of the study; in our hospital, there are more tasks related to education than in hospitals in other study settings. We also found differences between the wards in our study, which are mostly explained by differences in the patient mix, nurse staffing (proportion of nursing students), type of surgery and region of the body where the surgery was performed. However, we could not explain all differences. We made a first attempt in identifying and explaining differences in nurses' activities between wards, however this domain needs more research in order to better explain the differences.

BACKGROUND: Patients with recurrent or persisting complaints after an episode of left-sided diverticulitis are managed with either conservative measures or elective sigmoidectomy. To date, there are no data from randomised trials. We aimed to establish which treatment leads to a better quality of life for patients with diverticulitis. METHODS: We did an open-label, multicentre, randomised controlled trial (DIRECT trial) in 24 teaching and two academic hospitals in the Netherlands. Patients aged 18-75 years presenting with either recurrent (three or more presentations with clinical signs of acute diverticulitis within 2 years) or persistent abdominal complaints (ongoing lower left abdominal pain or persistent change in bowel habits for ≥3 months) after an episode of left-sided diverticulitis, confirmed by CT, ultrasound, or endoscopy, were included. Patients were excluded if they had previous elective or emergency surgery for acute sigmoid diverticulitis, an absolute operation indication, suspicion of a colorectal malignancy, with a preoperative or postoperative risk greater than III (on the American Society of Anesthesiologists classification), or were unable to complete questionnaire or follow-up. Patients were randomly assigned (3:3) to receive conservative management or elective (laparoscopic) sigmoidectomy using a digital randomisation system, stratified by type of disease and centre, with a block size of six. Patients, physicians, and researchers were not masked to treatment allocation. Our primary endpoint was health-related quality of life, measured by the Gastrointestinal Quality of Life Index (GIQLI) at 6 months after inclusion or surgery, depending on randomisation group. This trial is registered with trialregister.nl, number NTR1478, and is closed for inclusion. FINDINGS: Between July 1, 2010, and April 1, 2014, we randomly assigned 109 patients to receive surgical treatment (resection; n=53) or conservative management (n=56), after which the Data Safety and Monitoring Board prematurely terminated the trial because of increasing difficulties in recruitment. 47 (89%) of 53 patients received surgical treatment and 43 (77%) of 56 patients received conservative management. The GIQLI score at 6 months' follow-up was significantly higher in patients randomly assigned to receive surgical treatment (mean 114·4 [SD 22·3]) than conservative management (100·4 [22·7]; mean difference 14·2, 95% CI 7·2-21·1, p<0·0001). 43 (38%) of 109 patients had a severe adverse event in the first 6 months after treatment (18 [34%] of 53 patients in the surgical treatment group vs 23 [40%] of 57 patients in the conservative treatment group). Seven (15%) patients who received surgical treatment developed anastomotic leakage. Of the 56 patients assigned to be treated conservatively, 13 (23%) ultimately underwent elective resection due to ongoing abdominal complaints, with no anastomotic leakage. We recorded no patient deaths. INTERPRETATION: Elective sigmoidectomy, despite its inherent risk of complications, results in better quality of life than conservative management in patients with recurrent and persisting abdominal complaints after an episode of diverticulitis.

INTRODUCTION: Hospitals pursue different goals at the same time: excellent service to their patients, good quality care, operational excellence, retaining employees. This requires a good balance between patient needs and nursing staff. One way to ensure a proper fit between patient needs and nursing staff is to work with a workload management method. In our view, a nursing workload management method needs to have the following characteristics: easy to interpret; limited additional registration; applicable to different types of hospital wards; supported by nurses; covers all activities of nurses and suitable for prospective planning of nursing staff. At present, no such method is available. METHODS/ANALYSIS: The research follows several steps to come to a workload management method for staff nurses. First, a list of patient characteristics relevant to care time will be composed by performing a Delphi study among staff nurses. Next, a time study of nurses' activities will be carried out. The 2 can be combined to estimate care time per patient group and estimate the time nurses spend on non-patient-related activities. These 2 estimates can be combined and compared with available nursing resources: this gives an estimate of nurses' workload. The research will take place in an academic hospital in the Netherlands. 6 surgical wards will be included, capacity 15-30 beds. ETHICAL CONSIDERATIONS: The study protocol was submitted to the Medical Ethical Review Board of the University Medical Center (UMC) Utrecht and received a positive advice, protocol number 14-165/C. DISCUSSION: This method will be developed in close cooperation with staff nurses and ward management. The strong involvement of the end users will contribute to a broader support of the results. The method we will develop may also be useful for planning purposes; this is a strong advantage compared with existing methods, which tend to focus on retrospective analysis.

PURPOSE: An important factor in the decision to perform laparoscopic sigmoid resection for patient suffering from recurrent and ongoing diverticulitis is quality of life (QoL). It is unknown whether quality of life relates to the severity of diverticulitis as seen in the resected colonic segment. The aim of this study is to analyze histopathological findings of patients suffering from recurrent or ongoing diverticulitis and their QoL before and after surgery in order to improve patient outcome prediction. METHODS: A cohort of consecutive patients with diverticulitis between January 2010 and April 2014 was analyzed. All patients were scheduled for surgery and had at least three episodes of diverticulitis or more within the last 2 years or experienced ongoing complaints for at least 3 months or more and confirmation by a radiologist. We compared QoL questionnaires, to known histopathological entities. RESULTS: For this study, 54 consecutive patients were included, 15 (27.8%) men and 39 (72.2%) women. A marked difference in quality of life before and after surgery for patients having a more severe histopathological entity was not found (p = 0.83). However, a clinically relevant higher VAS score 6 months after surgery was shown in patients with peritonitis. Furthermore, these patients had more fibrosis in the histopathological samples. CONCLUSION: In conclusion, even though a relation between the different pathological entities and QoL could not be determined, patients with diverticulitis and concomitant microscopic peritonitis had significantly more fibrosis and suffered from a higher VAS scores 6 months after surgery.

BACKGROUND: It has been suggested that higher serum retinol levels could have protective effects on pulmonary function (PF) in patients with cystic fibrosis (CF). However, serum retinol levels will be transiently decreased during pulmonary exacerbation. Therefore, the extent of chronic pulmonary inflammation should be included when describing the association between PF and serum retinol. We assessed the longitudinal relation between serum retinol, immunoglobulin G (IgG) and PF in paediatric CF patients. METHODS: We studied the serum retinol, IgG and forced expiratory volumes in one second (FEV(1)% pred.) of 228 CF patients during a seven-year follow up period. The cross-sectional and longitudinal relations between these variables were assessed. RESULTS: Serum retinol, with medians levels between 1.2 and 1.4 µmol/l, were relatively stable, while median serum IgG gradually increased during the age years. The FEV(1)% pred. was longitudinally inversely associated with serum IgG and age, but not with serum retinol. Each g/l increase in serum IgG level was associated with an accelerated yearly decline in FEV(1)% pred. of 0.5% (95% CI -0.8 to -0.1, p=0.008), and each year increase in age was associated with a 1.7% (95% CI -2.1 to -1.3, p=0.000) decline in FEV(1)% pred. This effect was not observed with respect to serum retinol levels (95% CI -1.9 to 2.2, p=0.570). CONCLUSIONS: In this large sample of children and adolescents with CF, we found no evidence that higher serum retinol levels had protective effects on PF.

RATIONALE: An increase in the potency of the cannabis cigarettes has been observed over the past three decades. OBJECTIVES: In this study, we aimed to establish the impact of Δ9-tetrahydrocannabinol (THC) on the rating of subjective effects (intensity and duration of the effects), up to 23 % THC potency (69 mg THC) among recreational users. METHODS: Recreational users (N = 24) smoked cannabis cigarettes with four doses of THC (placebo 29, 49 and 69 mg of THC) on four separate test days in a randomized, double-blind, placebo-controlled, crossover study. The participants filled in three different questionnaires measuring subjective effects during the exposure up to 8 h post-smoking. The 'high' feeling, heart rate, blood pressure and THC serum concentrations were also regularly recorded during these 8 h. RESULTS: THC significantly increased the high feeling, dizziness, dry-mouthed feeling, palpitations, impaired memory and concentration, and 'down', 'sedated' and 'anxious' feelings. In addition, THC significantly decreased alertness, contentment and calmness. A cubic relationship was observed between 'feeling the drug' and 'wanting more'. The THC-induced decrease in 'feeling stimulated' and increase in anxiety lasted up to 8 h post-smoking. Sedation at 8 h post-smoking was increased by a factor of 5.7 with the highest THC dose, compared to the placebo. CONCLUSIONS: This study shows a strong effect of cannabis containing high percentages of THC on the rating of subjective effects. Regular users and forensic toxicologists should be aware that the THC-induced increase in 'feeling sedated' continues longer with a 69 mg THC dose than with a 29 mg THC dose.

Complete fundoplication (Nissen) has long been accepted as the gold standard surgical procedure in children with therapy-resistant gastroesophageal reflux disease (GERD); however, increasingly more evidence has become available for partial fundoplication as an alternative. The aim of this study was to perform a systematic review and meta-analysis comparing complete versus partial fundoplication in children with therapy-resistant GERD. PubMed (1960 to 2011), EMBASE (from 1980 to 2011), and the Cochrane Library (issue 3, 2011) were systematically searched according to the PRISMA statement. Results were pooled in meta-analyses and expressed as risk ratios (RRs). In total, eight original trials comparing complete to partial fundoplication were identified. Seven of these studies had a retrospective study design. Short-term (RR 0.64; p = 0.28) and long-term (RR 0.85; p = 0.42) postoperative reflux control was similar for complete and partial fundoplication. Complete fundoplication required significantly more endoscopic dilatations for severe dysphagia (RR 7.26; p = 0.007) than partial fundoplication. This systematic review and meta-analysis showed that reflux control is similar after both complete and partial fundoplication, while partial fundoplication significantly reduces the number of dilatations to treat severe dysphagia. However, because of the lack of a well-designed study, we have to be cautious in making definitive conclusions. To decide which type of fundoplication is the best practice in pediatric GERD patients, more randomized controlled trials comparing complete to partial fundoplication in children with GERD are warranted.

Aspergillus fumigatus is commonly found in the respiratory secretions of patients with cystic fibrosis (CF). Although allergic bronchopulmonary aspergillosis (ABPA) is associated with deterioration of lung function, the effects of A. fumigatus colonization on lung function in the absence of ABPA are not clear. This study was performed in 259 adults and children with CF, without ABPA. A. fumigatus colonization was defined as positivity of >50% of respiratory cultures in a given year. A cross-sectional analysis was performed to study clinical characteristics associated with A. fumigatus colonization. A retrospective cohort analysis was performed to study the effect of A. fumigatus colonization on lung function observed between 2002 and 2007. Longitudinal data were analysed with a linear mixed model. Sixty-one of 259 patients were at least intermittently colonized with A. fumigatus. An association was found between A. fumigatus colonization and increased age and use of inhaled antibiotics. In the longitudinal analysis, 163 patients were grouped according to duration of colonization. After adjustment for confounders, there was no significant difference in lung function between patients colonized for 0 or 1 year and patients with 2-3 or more than 3 years of colonization (p 0.40 and p 0.64) throughout the study. There was no significant difference in lung function decline between groups. Although colonization with A. fumigatus is more commonly found in patients with more severe lung disease and increased treatment burden, it is not independently associated with lower lung function or more severe lung function decline over a 5-year period.

OBJECTIVE: To address the association between depression and absolute levels of estradiol, and change in estradiol, among women during the menopausal transition. METHODS: This was a prospective, observational study conducted in Massachusetts, USA. Analyses reported here are based on the first three interviews following baseline (T1-T3). The participants were 309 women aged initially 43-53 years, who contributed a total of 728 observations (mean number of observations per subject 2.36). The main outcome measure was depression as measured by the Center for Epidemiologic Studies-Depression (CES-D) scale. RESULTS: CES-D score was not significantly associated with menopause status categories, nor was it associated with annual change in estradiol level (E2) (p = 0.19). The unadjusted association between log E2 and CES-D was negative (odds ratio 0.69) and statistically significant (p = 0.03). Upon adjustment for symptoms, however, the association remained negative but was no longer statistically significant (p = 0.26). Hot flushes/night sweats were positively associated with CES-D (p = 0.04), and trouble sleeping was strongly positively related to CES-D (p < 0.001). CONCLUSIONS: Results provide strong support for the domino or symptom hypothesis, which posits that depressed mood is caused by vasomotor symptoms associated with changing estrogen levels. Estradiol did not have a direct effect, independent of symptoms. This study adds to the body of literature suggesting that any association found between menopause and depression is most likely to be explained by other factors, such as symptoms and sleep problems. Findings also highlight the importance of studying the complex relationship between hormone levels, sleep problems and vasomotor symptoms during the menopausal transition.

OBJECTIVE: The purpose of this study was to address whether: (1) there is an association between menopause status and various aspects of sexual functioning, and (2) the relative contributions of menopause status and other variables to various aspects of sexual functioning. DESIGN: Analyses are based on 200 women from the Massachusetts Women's Health Study II, a population-based sample of women transitioning through the menopause who were not HRT users, who had not had a surgical menopause, and who had partners. The women were classified as pre-, peri-, or postmenopausal according to menstrual cycle characteristics. Estradiol, estrone, and follicle-stimulating hormone were also measured. Sexual functioning was measured in terms of satisfaction, desire, frequency of sexual intercourse, belief that interest declines with age, arousal compared with a younger age, difficulty reaching orgasm, and pain. Predictor variables included sociodemographics, health, vasomotor symptoms, psychological variables, partner variables, and lifestyle behaviors. RESULTS: Menopause status was significantly related to lower sexual desire, a belief that interest in sexual activity declines with age, and women's reports of decreased arousal compared with when in their 40s. Menopause status was unrelated to other aspects of sexual functioning in either unadjusted or multiple regression analyses. In analyses in which log estradiol (E2) was included in addition to menopause status, log E2 was only related to pain. In multiple regression analyses, other factors such as health, marital status (or new partner), mental health, and smoking had a greater impact on women's sexual functioning than menopause status. CONCLUSIONS: Menopause status, but not E2, is related to some, but not all, aspects of sexual functioning. This may be due to menopause per se or other factors associated with menopause and aging (e.g., increased sexual dysfunction among aging men). Menopause status has a smaller impact on sexual functioning than health or other factors.

A community-based survey was conducted during 1995-1997 of factors related to menopausal and other symptoms in a multi-racial/ethnic sample of 16,065 women aged 40-55 years. Each of seven sites comprising the Study of Women's Health across the Nation (SWAN) surveyed one of four minority populations and a Caucasian population. The largest adjusted prevalence odds ratios for all symptoms, particularly hot flashes or night sweats (odds ratios = 2.06-4.32), were for women who were peri- or postmenopausal. Most symptoms were reported least frequently by Japanese and Chinese (odds ratios = 0.47-0.67 compared with Caucasian) women. African-American women reported vasomotor symptoms and vaginal dryness more (odds ratios = 1.17-1.63) but urine leakage and difficulty sleeping less (odds ratios = 0.64-0.72) than Caucasians. Hispanic women reported urine leakage, vaginal dryness, heart pounding, and forgetfulness more (odds ratios = 1.22-1.85). Hot flashes or night sweats, urine leakage, and stiffness or soreness were associated with a high body mass index (odds ratios = 1.15-2.18 for women with a body mass index > or =27 vs. 19-26.9 kg/m2). Most symptoms were reported most frequently among women who had difficulty paying for basics (odds ratios = 1.15-2.05), who smoked (odds ratios = 1.21-1.78), and who rated themselves less physically active than other women their age (odds ratios = 1.24-2.33). These results suggest that lifestyle, menstrual status, race/ethnicity, and socioeconomic status affect symptoms in this age group.

Low circulating levels of the adrenal steroids dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are thought to be associated with increased risk of cardiovascular disease (CVD) in men. In women, either a positive or null association with CVD has been found. The nature of the relation between DHEAS and CVD risk factors in women is unclear and is based on cross-sectional data. We present results from a longitudinal investigation of serum DHEA and DHEAS and cardiovascular disease risk factors in 236 women, initially 50-60 years old, from a population-based prospective (1986-1995) study of the menopausal transition. We used generalized estimating equations to model the relation of serum DHEA and DHEAS to systolic and diastolic blood pressure and serum levels of total cholesterol, high density lipoprotein cholesterol, and apolipoproteins A and B, adjusting for other factors related to CVD. Both DHEA and DHEAS were positively related to diastolic and systolic blood pressure, and DHEAS was negatively related to apolipoprotein A. DHEA and DHEAS were also positively related to smoking, alcohol use, estrone, and estradiol levels, and inversely related to age. Our results suggest that higher levels of DHEA and DHEAS in middle-aged women may indicate increased CVD risk.
