Background Previous studies have shown that poor family environments are related to more sleep problems; however, little is known about how family irregularity in early life affects the development of sleep problems over childhood using objective sleep measures. The current study tests the hypothesis that early family irregularity contributes to the development of sleep problems. Methods This population‐based study comprises 5,443 children from the Generation R Study. Family irregularity was measured with seven maternal‐reported questions on family routines when children were 2 and 4 years old. Mothers reported on sleep problems at child age 3, 6, and 10 years, whereas children completed questionnaires on sleep problems at age 10. Additionally, we used tri‐axial wrist accelerometers for five nights in 851 children (mean age 11.7 years) to assess sleep objectively. Results Family irregularity was associated with more mother‐ and child‐reported sleep problems at ages 3, 6, and 10 years as well as with a shorter sleep duration and later objective sleep onset, but not with sleep efficiency or waking time. The association between family irregularity and multi‐informant subjective sleep problems at age 10 years was mediated by mother‐reported child psychopathology at age 6 years. Conclusions Our findings show a long‐term robust association of preschool family irregularity with more sleep problems during childhood as well as shorter sleep duration and later sleep onset as measured objectively with actigraphy. In part, these sleep problems were associated with family irregularity by way of child psychopathology. These findings suggest that interventions improving preschool family irregularity, which are targeted to reduce child psychopathology, may also impact the development of sleep problems beneficially.

Schizophrenia and bipolar disorder (BD) are heritable disorders with similarities in clinical symptoms and typical onset after puberty. While research shows that impaired motor coordination can have an associationwith schizophrenia, there are limited data on childhood development preceding BD. Murray et al proposed a developmental model for similarities and dissimilarities between schizophrenia and BD, but it remains unknown if dissimilarities exist in early infancy and if they covary with genetic liability for these disorders. Using polygenic risk scores (PRSs),we exploredwhether genetic risk for schizophrenia and genetic risk for BD are associated with neuromotor development in infancy.

With this prospective population-based study, we showed that infant neuromotor development, including muscle tone and senses, predicted internalizing problems but not externalizing problems through age 10 years. BACKGROUND: Research of adults and school-aged children suggest a neurodevelopmental basis for psychiatric disorders. We examined whether infant neuromotor development predicted internalizing and externalizing problems in young children. METHODS: In Generation R, a population-based cohort in the Netherlands (2002–2006), trained research assistants evaluated the neuromotor development of 4006 infants aged 2 to 5 months by using an adapted version of Touwen’s Neurodevelopmental Examination (tone, responses, and senses and other observations). We defined nonoptimal neuromotor development as scores in the highest tertile. Mothers and fathers rated their children’s behavior at ages 1.5, 3, 6, and 10 years with the Child Behavior Checklist (n = 3474, response: 86.7%). The associations were tested with generalized linear mixed models. RESULTS: Overall, neuromotor development predicted internalizing scores, but no association was observed with externalizing scores. Nonoptimal muscle tone was associated with higher internalizing scores (mothers’ report: β = .07; 95% confidence interval [CI]: 0.01 to 0.13; fathers’ report: β = .09, 95% CI: 0.00 to 0.16). In particular, nonoptimal low muscle tone was associated with higher internalizing scores (mothers’ report: β = .11; 95% CI: 0.05 to 0.18; fathers’ report: β = .13; 95% CI: 0.04 to 0.22). We also observed an association between senses and other observations with internalizing scores. There was no relationship between high muscle tone or reflexes and internalizing scores. CONCLUSIONS: Common emotional problems in childhood have a neurodevelopmental basis in infancy. Neuromotor assessment in infancy may help identify vulnerability to early internalizing symptoms and offer the opportunity for targeted interventions.

In a longitudinal population‐based study of 2,905 children, we investigated if infants' neuromotor development was associated with autistic traits in childhood. Overall motor development and muscle tone were examined by trained research assistants with an adapted version of Touwen's Neurodevelopmental Examination between ages 2 and 5 months. Tone was assessed in several positions and items were scored as normal, low, or high tone. Parents rated their children's autistic traits with the Social Responsiveness Scale (SRS) and the Pervasive Developmental Problems (PDP) subscale of the Child Behavior Checklist at 6 years. We defined clinical PDP if scores were >98th percentile of the norm population. Diagnosis of autism spectrum disorder (ASD) was clinically confirmed in 30 children. We observed a modest association between overall neuromotor development in infants and autistic traits. Low muscle tone in infancy predicted autistic traits measured by SRS (adjusted beta = 0.05, 95% CI for B: 0.00–0.02, P = 0.01), and PDP (adjusted beta = 0.08, 95% CI for B: 0.04–0.10, P < 0.001). Similar results emerged for the association of low muscle tone and clinical PDP (adjusted OR = 1.36, 95% CI: 1.08–1.72, P = 0.01) at age 6 years. Results remained unchanged if adjusted for child intelligence. There was no association between high muscle tone and SRS or PDP. Exclusion of children with ASD diagnosis did not change the association. This large study showed a prospective association of infant muscle tone with autistic traits in childhood. Our findings suggest that early detection of low muscle tone might be a gateway to improve early diagnosis of ASD.

Within a population-based study of 3356 children, we investigated whether infant neuromotor development was associated with cognition in early childhood. Neuromotor development was examined with an adapted version of Touwen's Neurodevelopmental Examination between 9 and 20 weeks. Parents rated their children's executive functioning at 4 years. At age 6 years, children performed intelligence and language comprehension tests, using Dutch test batteries. At age 6-9 years, neuropsychological functioning was assessed in 486 children using the validated NEPSY-II-NL test battery. We showed that less optimal neurodevelopment in infancy may predict poor mental rotation, immediate memory, shifting, and planning; but not nonverbal intelligence or language comprehension.

p53 is one of the most frequently mutated genes in human tumors including head and neck tumors like oral squamous cell carcinoma. It might be responsible for more than 50% of all relapses in patients with surgically treated oral carcinoma and clean margins. The aim of the present study was to explore p53 protein expression in peritumoral tissue and correlate it with relapse of the disease. The study included 25 patients (17 males and 8 females) with oral squamous cell carcinoma in the period August 2006 till August 2008. For immunohistochemical assay, a monoclonal antibody against p53 protein was applied (clone DO-7, DAKO Glostrup, Denmark). Peritumoral expression of p53 was as follows: 10 out of 25 cases (40%) were negative, 2 cases (8%) showed weak, 5 cases (20%) moderate and 8 cases (32%) strong p53 positivity. No significant correlation between peritumoral expression of p53 protein and patient's relapse was found. In contrast, we found a trend toward association between intratumoral p53 expression and patient's relapse (p = 0.07). There was also trend toward higher peritumoral p53 expression in females comparing with p53 expression in males (52.9% of males did not have p53 expression while 87.5% females had mild, moderate or high p53 expression, p = 0.088). Peritumoral expression of p53 protein is frequently seen in oral squamous cell carcinoma and merits further research.

SUMMARY We report an outbreak associated with a dinner cruise on Lake Michigan. This took place on the same day as heavy rainfall, which resulted in 42·4 billion liters of rainwater and storm runoff containing highly diluted sewage being released into the lake. Of 72 cruise participants, 41 (57%) reported gastroenteritis. Stool specimens were positive for Shigella sonnei (n=3), Giardia (n=3), and Cryptosporidium (n=2). Ice consumption was associated with illness (risk ratio 2·2, P=0·011). S. sonnei was isolated from a swab obtained from the one of the boat's ice bins. Environmental inspection revealed conditions and equipment that could have contributed to lake water contaminating the hose used to load potable water onto the boat. Knowledge of water holding and distribution systems on boats, and of potential risks associated with flooding and the release of diluted sewage into large bodies of water, is crucial for public health guidance regarding recreational cruises.

In April 2009, following the first school closure due to 2009 pandemic influenza A (H1N1) (pH1N1) in Chicago, Illinois, area hospitals were inundated with patients presenting with influenza-like illness (ILI). The extent of disease spread into the surrounding community was unclear. We performed a household survey to estimate the ILI attack rate among community residents and compared reported ILI with confirmed pH1N1 cases and ILI surveillance data (ie, hospital ILI visits, influenza testing, and school absenteeism). The estimated ILI attack rate was 4.6% (95% confidence interval, 2.8%-7.4%), with cases distributed throughout the 5-week study period. In contrast, 36 (84%) of 43 confirmed pH1N1 cases were identified the week of the school closure. Trends in surveillance data peaked during the same week and rapidly decreased to near baseline. Public awareness and health care practices impact standard ILI surveillance data. Community-based surveys are a valuable tool to help assess the burden of ILI in a community.

This paper focuses on the importance of adaptation of evidence based clinical practice guidelines (CPG) in developing countries like Bosnia and Herzegovina in a culturally competent way. Evidence based CPG guidelines are not routinely used in Bosnia and Herzegovina. The first adapted, evidence-based guideline on the care of women requesting induced abortion was published in 2007 following a 2004 publication by the Royal College of Obstetricians and Gynecologists (RCOG) (Evidence-based Clinical Guideline Number 7, ‘The Care of Women Requesting Induced Abortion’). The first adapted clinical guideline initiated the development of a second one related to secondary prevention of cervical carcinoma. Appraisal of Guidelines for Research and Evaluation (AGREE) were used to assess the development of clinical practice guidelines with the purpose of assuring methodological quality. After receiving permission, electronic searches of medical databases were performed to identify research performed in international settings similar to ours and research that took place after the publication of the RCOG guideline. 226 articles were selected, yielding 68 recommendations related to clinical assessment questions. Using expert consensus and external reviews, recommendations were generated that provided the clinical guideline development group with an evidence base from which to make recommendations on the best possible clinical practice. Variation in values, needs, costs and resources were considered systematically in order to make a decision about which policies should be implemented locally. For the first time in B&H, the evidenced-based clinical guideline development process fostered a supportive environment for educating health care providers on evidence based methodology, and new evidence based guidelines can be initiated for potential health care providers.

The aim of this study was to investigate expression of cyclin D1, bcl-2, p53, Ki-67 and HER-2 proteins in 14 cases of non-small cell lung cancer and to establish their correlation to classical clinico-pathological findings, and alleged prognostic value to estimate biological potential of tumor. Retrospective pilot study of the surgically treated non-small cell lung cancer biopsy specimen, paraffin embedded, used immunohistochemical method to demonstrate expression of cyclin D1, bcl-2, p53, Ki-67 and HER-2. Protein quantification was performed by the semi-quantitative method. Achieved results were correlated with classical clinico-pathological parameters, like tumor size, histological type, differentiation level, presence of vascular invasion and metastasis in regional lymph nodes. Out of 14 cases of non-small cell lung cancer, squamous cell carcinoma was found in 7 patients, giant cell carcinoma in 3, adenocarcinoma in 2, and 1 case of pleomorphic and mucoepidermoid carcinoma. Expression of cyclin D1 was not found, while expression of HER-2 and bcl-2 protein was established in one cases each. p53 expression was noted in 8 cases (57,1%). Statistically positive significant correlation (p<0,05) was found among: presence of lymphovascular invasion to tumor tissue and appearance of nodal metastasis; proliferation Ki-67 index and level of tumor differentiation, i.e. size of tumor. Other investigated parameters showed no significant statistically dependence. p53 expression was not correlated to any of the investigated parameters what might imply the possibility that there is an independent pathway of this protein expression. Negative expression of bcl-2 protein points out to possibility that it is not included into process of tumor apoptosis, as well as that proteins cyclin D1 and HER-2 are not included into processes of the tumor genesis. Since the proliferative activity of the tumor, measured by the expression of Ki-67, is correlated to the gradus and size of the tumor mass, Ki-67 protein can be of a prognostic value to determine biological potential of non-small cell lung cancer.

Retrospective study was conducted in surgical intensive care unit (ICU) in Clinical Hospital Center Zagreb in 2005. The aim of study was to create guidelines for empirical antibiotic therapy of sepsis in ICU for unknown causative agent based on antimicrobial susceptibility of causative bacteria. Thirty-two patients with severe sepsis were included in study and from medical records their clinical and microbiological data were analyzed. Antimicrobial susceptibility of the strains isolated from the blood-culture was tested by disk diffusion method according to CLSI (Clinical Laboratory Standard Institution). We used APACHE II score to predict the severity of illness. Mann-Whitney test and chi2 test were used to test statistical significance difference between results. Acinetobacter baumannii and Pseudomonas aeruginosa were the predominant causative agent. Acinetobacter baumannii was displaying excellent susceptibility to ampicillin+sulbactam and carbapenems, whereas Pseudomonas aeruginosa was showed good susceptibility on ceftazidim and carbapenems. Methicillin-resistant Staphylococcus aureus (MRSA), third predominant causative agent exhibiting good susceptibility to vancomycin and linezolide. The recommended therapy is empirical antibiotic therapy and should cover all important pathogens.
