Association between type 2 diabetes and depressive symptoms after a 1-year follow-up in an older adult Mediterranean population.

OBJECTIVES: To examine the cross-sectional association between baseline depressive symptoms and the presence of type 2 diabetes (T2D), and its association with glycated hemoglobin (HbA1c) and other metabolic variables, and the prospective association of depressive symptoms and HbA1c after 1 year of follow-up. METHODS: n = 6224 Mediterranean older adults with overweight/obesity and metabolic syndrome (48% females, mean age 64.9 ± 4.9 years) were evaluated in the framework of the PREDIMED-Plus study cohort. Depressive symptoms were assessed using the Beck Depression Inventory-II and HbA1c was used to measure metabolic control. RESULTS: The presence of T2D increased the likelihood of higher levels of depressive symptoms (χ2 = 15.84, p = 0.001). Polynomial contrast revealed a positive linear relationship (χ2 = 13.49, p = 0.001), the higher the depressive symptoms levels, the higher the prevalence of T2D. Longitudinal analyses showed that the higher baseline depressive symptoms levels, the higher the likelihood of being within the HbA1c ≥ 7% at 1-year level (Wald-χ2 = 24.06, df = 3, p < .001, for the full adjusted model). Additionally, depressive levels at baseline and duration of T2D predicted higher HbA1c and body mass index, and lower physical activity and adherence to Mediterranean Diet at 1 year of follow-up. CONCLUSIONS: This study supports an association between T2D and the severity of depressive symptoms, suggesting a worse metabolic control from mild severity levels in the short-medium term, influenced by lifestyle habits related to diabetes care. Screening for depressive symptoms and a multidisciplinary integrative therapeutic approach should be ensured in patients with T2D.

Clinicians' attitudes toward standardized assessment and diagnosis within child and adolescent psychiatry.

BACKGROUND: There is a strong call for clinically useful standardized assessment tools in everyday child and adolescent psychiatric practice. The attitudes of clinicians have been raised as a key-facilitating factor when implementing new methods. An explorative study was conducted aimed to investigate the clinicians' attitudes regarding standardized assessments and usefulness of diagnoses in treatment planning. METHODS: 411 mental health service personnel working with outpatient and inpatient assessment and treatment within the specialist child and adolescent mental health services, Stockholm County Council were asked to participate in the study, of which 345 (84%) agreed answer a questionnaire. The questionnaire included questions regarding Attitudes toward Standardized Assessment and Utility of Diagnosis. Descriptive analyses were performed and four subscales were compared with information from a similar study in US using the same instruments. The demographic and professional characteristics (age, working years, gender, education, profession, management position, involvement in assessment, level of service) in terms of prediction of attitudes were studied by univariate and multivariate linear regressions. RESULTS: Overall, the clinicians had quite positive attitudes and were more positive compared to a similar study conducted in the US earlier. There were differences in attitudes due to several characteristics but the only characteristic predicting all subscales was type of profession (counselor, nurse, psychiatrist, psychologist, other), with counselors being less positive than other groups. CONCLUSION: The overall positive attitudes toward standard assessment are of importance in the development of evidence-based practice and our study implies that clinicians in general value and are willing to use standardized assessment. Nevertheless, there are specific issues such as adequate training and available translated assessment instrument that need to be addressed. When implementing new methods in practice, there are general as well as specific resistances that need to be overcome. Studies in different cultural settings are of importance to further extend the knowledge of what is general and what is specific barriers.

Effect of xylanases on ileal viscosity, intestinal fiber modification, and apparent ileal fiber and nutrient digestibility of rye and wheat in growing pigs.

Two experiments were performed to study the effect of xylanase on ileal extract viscosity, in vivo fiber solubilization and degradation, and apparent ileal digestibility (AID) of fiber constituents, OM, CP, starch, and crude fat in rye and wheat in ileal-cannulated pigs. In Exp. 1, coarse rye without (NX) or with addition of xylanase from Aspergillus niger (AN), (BS), or (TR) was fed to 8 ileal-cannulated barrows (initial BW 30.9 ± 0.3 kg) for 1 wk each according to a double 4 × 4 Latin square design. In Exp. 2, fine rye, fine wheat, and coarse wheat with or without a combination of xylanase from and were fed to 6 ileal-cannulated barrows (initial BW 33.6 ± 0.5 kg) for 1 wk according to a 6 × 6 Latin square design with a 2 × 3 factorial arrangement of enzyme and cereal matrix. Chromic oxide (0.2%) was used as an inert marker. Ileal effluent was collected for 8 h on d 5 and 7 and pooled for analysis. In Exp. 1, TR reduced intestinal viscosity of pigs fed rye from 9.3 mPa·s in the control diet (NX) to 6.0 mPa·s ( < 0.001), whereas AN and BS had no effect. None of the enzymes changed the concentration of total arabinoxylan, high-molecular-weight arabinoxylan (HMW-AX), or arabinoxylan oligosaccharides (AXOS) in the liquid phase of digesta. In Exp. 2, the enzyme combination reduced intestinal viscosity for all 3 cereal matrices ( < 0.05), but the viscosity was much higher with fine rye (7.6 mPa·s) than with fine and coarse wheat (<1.7 mPa·s). Simultaneously, the total concentration of arabinoxylan in the liquid phase of digesta increased by 82.4% in fine wheat ( < 0.002) and by 45.9% in coarse wheat ( < 0.006), and AXOS increased 16-fold with enzyme addition. Similar effects of enzyme were not seen with rye. The concentration of xylooligosaccharides in the liquid phase of digesta increased with enzyme addition, but for xylose, it was only significant for wheat, for which it increased 3.9-fold ( < 0.001). None of the xylanases affected AID of arabinoxylan of rye in Exp. 1. In Exp. 2, the enzyme combination increased AID of arabinoxylan by 91% to 107% ( < 0.001) across cereal matrices. Enzyme addition did not affect AID of nutrients in any of the experiments except for a higher starch and crude fat digestibility of fine wheat with enzyme addition ( < 0.012) in Exp. 2. Collectively, the results suggest that xylanase is more efficient in degrading arabinoxylan from wheat than from rye.

Xylanase increased the ileal digestibility of nonstarch polysaccharides and concentration of low molecular weight nondigestible carbohydrates in pigs fed high levels of wheat distillers dried grains with solubles.

The objective was to study the effect of a commercially available xylanase (CAX), an experimental xylanase (EX), and EX in combination with protease (EXP) on the degradation of nondigestible carbohydrates (NDC) and apparent ileal digestibility (AID) of nutrients in wheat distillers dried grains with solubles (wDDGS). The control and 3 enzyme diets contained 96% wDDGS supplemented with vitamins, minerals, L-lysine, and chromic oxide as a digestibility marker in addition to enzyme premix. Eight ileal cannulated pigs were fed 4 experimental diets containing 96% wDDGS-a control diet or 1 of 3 diets with CAX, EX, or EXP-in a double 4 × 4 Latin square design. The experimental period lasted 7 d; adaptation lasted 4 d, and the ileal digesta were collected for 8 h on d 5 and 7, when spot samples of feces were also collected. Digesta samples were analyzed for NDC, total and soluble nonstarch polysaccharides (NSP), low molecular weight (LMW) NDC, OM, CP, fat, starch, and marker. Compared with the control diet, addition of CAX, EX, and EXP increased the AID of arabinoxylan by 32 (P < 0.001), 28 (P = 0.001), and 24% (P = 0.004), respectively. In addition, EXP increased the AID of noncellulosic polysaccharide glucose by 21% compared with the control (P = 0.005). Compared with the control, addition of EX, EXP, and CAX decreased the concentration of soluble arabinoxylan in ileal digesta by 40 (P < 0.0001), 40 (P < 0.0001), and 21% (P = 0.022), respectively. Furthermore, addition of CAX, EXP, and EX increased the concentration of LMW arabinoxylan in ileal digesta by 40 (P = 0.0001), 36 (P = 0.0006), and 24% (P = 0.023), respectively, compared with the control. Addition of EX and EXP decreased the concentration of soluble NSP of ileal digesta by 25 (P = 0.001) and 26% (P < 0.001), respectively, compared with the control diet. Addition of CAX (P < 0.0001) and EXP (P = 0.013) increased the arabinose-to-xylose ratio in the insoluble arabinoxylan fraction in ileal digesta compared with the control diet, and CAX increased the uronic acid-to-xylose ratio of the ileal insoluble NSP fraction (P < 0.0001) compared with the control diet. Enzyme addition did not affect AID of OM, CP, starch, and fat (P > 0.3). In conclusion, addition of xylanases to wDDGS diets increased the ileal digestibility of NSP and generated LMW NDC components in the small intestine of pigs but did not affect ileal digestibility of nutrients in the current study.

Contribution of protein, starch, and fat to the apparent ileal digestible energy of corn- and wheat-based broiler diets in response to exogenous xylanase and amylase without or with protease.

The ileal energy contribution of protein, starch, and fat in response to 2 exogenous enzyme combinations was studied in 2 digestibility assays with 21- (experiment 1; 432 birds) and 42-d-old (experiment 2; 288 birds) Ross 308 broiler chickens. A 2 × 2 × 3 factorial arrangement of treatments with 2 base grains (corn or wheat), without or with high fiber ingredients (corn distillers dried grains with solubles and canola meal), and 3 enzyme treatments was implemented. Enzyme treatments, fed from 12 to 21 d or 32 to 42 d, were 1) without enzymes, 2) with xylanase from Trichoderma ressei (2,000 U/kg) and amylase from Bacillus licheniformis (200 U/kg; XA), or 3) with XA plus protease from Bacillus subtilis (4,000 U/kg; XAP). All diets contained Escherichia coli phytase (500 FTU/kg). Apparent ileal digestibility (AID) of protein, starch, and fat, as well as the apparent ileal digestible energy, were determined using titanium dioxide as inert marker. A generalized mixed model was used to test main effects and 2-way interactions at P < 0.05. An enzyme × grain interaction was detected for AID of starch at 21 and 42 d, and AID of fat at 21 d, with greater effects of enzymes in wheat-based compared with corn-based diets, but significant increments due to enzymes compared with controls in both diet types. Apparent ileal digestibility of fat at 42 d increased with enzyme supplementation compared with the control treatments. The XA and XAP treatments gradually (P < 0.05) increased AID of protein at 21 d, but only XAP increased AID of protein compared with the control at 42 d. Compared with the controls, XA increased AID energy by 52 or 87 kcal, and XAP by 104 or 152 kcal/kg of DM at 21 or 42 d, respectively. The caloric contribution of starch, fat, and protein were affected differentially by base grain and the presence of fibrous ingredients at 21 and 42 d of age.

Non-uniform phenotyping of D12S391 resolved by second generation sequencing.

Non-uniform phenotyping of five case work samples were observed in the D12S391 locus. The samples were typed at least twice with the AmpFℓSTR NGM SElect PCR Amplification Kit and different alleles were called with GeneMapper ID-X in the different experiments. Detailed analyses of the electropherograms suggested that the individuals were heterozygous with two alleles that differed in size by one nucleotide. This was confirmed by amplifying the samples with the PowerPlex ESX 17 system. D12S391 is a complex STR with variable numbers of AGAT and AGAC repeats. Second generation sequencing revealed that separation of two alleles differing by one nucleotide in length was poor if the number of AGAT repeats in the short allele was higher than in the long allele. A total of 45 individuals with microvariants or off-ladder alleles in D12S391 were sequenced. Thirty different alleles were detected and sixteen of these were not previously reported.

Association between Attention-Deficit Hyperactivity Disorder in childhood and schizophrenia later in adulthood.

PURPOSE: To estimate the risk of schizophrenia in adulthood among children and adolescents with ADHD compared to the background population. SUBJECTS/MATERIALS AND METHODS: Two hundred and eight youths with ADHD (183 boys; 25 girls) were followed prospectively. Diagnoses of schizophrenia were obtained from The Danish Psychiatric Central Register. The relative risk (RR) of schizophrenia for cases with ADHD, compared to the normal population, was calculated as risk ratios. Hazard ratios (HR's) by Cox regression were calculated in the predictor analyses. RESULTS: Mean age for ADHD cases at follow-up was 31.1years. Schizophrenia diagnoses were given to 3.8% of these cases. Compared to the general population, RR of schizophrenia in cases with ADHD was 4.3 (95% CI 1.9-8.57). DISCUSSION AND CONCLUSION: This prospective follow-up study found children with ADHD to be at higher risk of later schizophrenia than controls. If replicated, these results warrant increased focus on the possible emergence symptoms of schizophrenia or schizophreniform psychosis during clinical follow-up of patients with ADHD.

Interactions of phytate and myo-inositol phosphate esters (IP1-5) including IP5 isomers with dietary protein and iron and inhibition of pepsin.

Phytic acid (IP(6)) and myo-inositol phosphate esters (IP(1-5)), including IP(5) isomers prepared chemically and enzymatically with bacterial and fungal phytases, were examined for their effects on protein aggregation of soy protein and ß-casein, interaction with Fe(3+), and pepsin activity. The results indicated that the aggregating capabilities of IP esters (IP(1-6)) on the 2 proteins decreased dramatically from IP(6) to IP(5) and became negligible with IP(1-4). Among the IP(5) isomers tested, InsP(5)(1,2,3,4,5) produced by 6-phytase was slightly less powerful in aggregating protein than InsP(5)(1,2,4,5,6) produced by 3-phytase (P = 0.001). For protein hydrolysis, IP esters of IP(3-4) still showed inhibition of pepsin though to a lesser extent than IP(5-6). The in vitro data with IP(1-5) generated with microbial 3- and 6-phytases indicate that, for complete alleviation of pepsin inhibition, IP(6) needs to be broken down to IP(1-2.) In contrast to the aggregation with protein, the reactivity of IP(1-6) toward Fe(3+) decreased proportionally from IP(6) to IP(3.) Based on the radical decrease in turbidity of IP(6) -protein complex observed, as a result of IP(6) dephosphorylation to IP(5), a novel qualitative and semi-quantitative phytase plate assay was established using IP(6)-protein complex incorporated into an agarose petri-dish as substrate. Phytase activity was shown as the development of clear halos on the agarose plate with time. This simple phytase plate assay method can be used at animal farms, control laboratories, and even for the screening of engineered phytase variants. The current study, thus, stresses the importance of the efficient hydrolysis of IP(6) at lower pH range to alleviate the negative effect of phytic acid and its degradation products on protein and Fe(3+) digestion.

Comparison of four feed proteases for improvement of nutritive value of poultry feather meal.

Feed industries are seeking new ways to cope with increased raw material costs, and one approach is to apply enzymatic treatment in the production of feed ingredients from animal by-products. Keratinases, a group of proteases, are capable of hydrolyzing keratin-rich material and have been applied in the production of cost-effective feather by-products for use as feed and fertilizers. The current study examined 4 commercial feed proteases from Bacillus subtilis, Bacillus licheniformis PWD-1, Aspergillus niger, and Serratia proteamaculans HY-3 used to hydrolyze chicken feather under different conditions. The degree of keratinolysis was monitored by measuring the release of NH(2) groups using o-phthalaldehyde (OPA) and by scanning electron microscopy. All 4 feed proteases were able to degrade feather at pH 5.5 and 7.0. The degree of hydrolysis was stimulated by the addition of reducing reagents such as dithiothreitol (DTT) and Na(2)SO(3). In general, the protease from B. subtilis was more efficient in degrading feather keratin compared to the other 3 feed proteases at both pH 5.5 and 7.0. For commercial production, the application of protease from B. subtilis is even more advantageous considering the lower cost-in-use.

[Evidence-based treatment of ADHD/DAMP in children and adolescents with central stimulants]. / Evidensbaseret behandling af ADHD/DAMP-børn og unge med centralstimulerende medicin.

The use of stimulants in the treatment of children and adolescents with Attention Deficit Hyperactivity Disorder, ADHD, and Deficit in Attention, Motor Control and Perception, DAMP, is often considered somewhat controversial. It was first used in 1937, and since the 1960s, 3000 published studies and 250 reviews have demonstrated the positive, short-term effect of stimulants on children and adolescents with ADHD/DAMP. More than 160 randomised, controlled trials (RCT) have studied the effect of attention, hyperactivity, and impulsivity. Furthermore, stimulants have proved effective on the social relation of such children, both in their families and in with their peers. Side effects are often mild, transient and dose-related. The short-term effectiveness of stimulants is thus well-documented and their prescription evidence-based, whereas further studies on the long-term effect are needed.

Reassessment of ADHD in a historical cohort of children treated with stimulants in the period 1969-1989.

The operational diagnostic criteria for ADHD or HKD were not at hand in Denmark before 1994, when WHO's International Classification of Diseases -10 (ICD-10) was introduced. The criteria for ADHD/HKD were well known at our clinic, but when treating children with stimulants the criteria used clinically prior to 1994 were less specific than today. The aims of this paper are to examine the prevalence of ADHD in a historical cohort of children treated with stimulants during the period 1969-1989 and to reassess a wide range of comorbid disorders and sociodemographic characteristics in order to compare aspects of the given treatment with the modern recommendations. At our clinic 208 children (183 boys) were given stimulants during the period 1969-1989. Case records on these probands were reassessed retrospectively for DSM-IV criteria regarding ADHD and comorbid disorders as well as for characteristics of stimulant treatment. Sixty-five percent met full criteria for an ADHD diagnosis. Including Subthreshold ADHD as many as 81 % of the cohort were re-diagnosed with ADHD. Prevalence rates of conduct problems and anxiety disorder were similar to previous prospective ADHD studies. The use of stimulants during the period 1969-1989 were in accord with modern guidelines. This cohort is comparable to other clinically based ADHD cohorts as regards inattentive, hyperactive/impulsive symptoms, comorbidity, impairment, gender differences, intelligence and socio-economic status (SES).

Gilles de la Tourette syndrome in a child with congenital deafness.

We present the case of a 10-year-old boy, Sam, with congenital deafness and Gilles de la Tourette Syndrome (GTS). GTS is characterised by multiple motor tics and one or more vocal tics that wax and wane. Due to his deafness Sam never developed vocal language but instead used sign language from the age of four. His tic disorder rapidly accelerated from the age of seven over a six-month period and soon sign language was incorporated into tics as complex "vocal" tics. Bursting out "words" in sign language would also occur in front of people unfamiliar with sign language and often with an obscene content although this was not evident to someone not trained in sign language. To our knowledge this is the first reported case of a congenital deaf child with GTS. The case presented here supports previously published work that the intentional share of the tics in GTS is very small. This case also questions former theories on which regions and circuits of the brain are involved in GTS.

Elective cholecystectomy increases plasma amino-acid clearance and hepatic capacity for urea synthesis for one week.

The importance of the liver in post-operative catabolism was studied in 6 cholecystectomy patients given a mixture of amino-acids as prime-continuous infusions pre-operatively and on the 1st, 3rd, 6th and 12th post-operative day. The plasma clearance of total alpha-amino-nitrogen and of single amino-acids, the urea-nitrogen synthesis rate, and the functional hepatic nitrogen clearance were calculated. Surgery decreased fasting blood amino-nitrogen concentration by 15% (p < 0.01), and increased the plasma clearance of amino-nitrogen by 30% (P < 0.05) on the 1st, 3rd and 6th post-operative day. Surgery doubled the functional hepatic nitrogen clearance (p < 0.01) on the 1st, 3rd and 6th post-operative day. This indicates that post-operative stress catabolism is partly due to a hepatic condition by which the liver eliminates more amino-nitrogen despite lower amino-acid concentration in the blood, for one week post-operatively.

Achilles tendon ruptures operated on under local anesthesia. Retrospective study of 81 nonhospitalized patients.

During a 6-year period, 97 patients with an acute rupture of the Achilles tendon were operated on under local anesthesia as outpatients. At follow-up, 5/81 patients had some discomfort. A rerupture occurred in 3 patients shortly after commencing weight bearing and after substantial traumas. We conclude that there is no need to hospitalize patients with an Achilles tendon rupture.

The social and economic consequences of failure to replant amputated thumbs.

Thirty-two patients with amputated thumbs were admitted to hospital. In none was replantation considered to be feasible because of the serious damage to the soft tissues and the bone damage. The social and economic consequences are discussed.

Wilson shaft osteotomy for hallux valgus.

The results of a modified Wilson shaft osteotomy for hallux valgus in 77 feet of 51 patients were excellent or good in 62 feet after 2 to 4 years. The correction of the hallux valgus angle and intermetatarsal angle was excellent or good in 69 feet. The operation is technically simple provided dorsal angulation of the distal fragment is avoided in the early postoperative period.

Duodenal ulcer with perforation to the inferior vena cava. Report of a fatal case.

A fatal case of duodenal ulcer with perforation to the inferior vena cava is described. This rare cause of gastrointestinal hemorrhage should be considered when the bleeding is severe. The risk of sepsis is high in such cases.
