Abstract
OBJECTIVES With the COVID-19 pandemic, psychiatry residencies (academic, community, and hybrid) have adopted different learning modalities to preserve a high quality of educational training. There is minimal data on specific program adaptations, related change perspectives, and program type stratification. This study aims to analyze trends in curriculum changes in accredited psychiatry residency programs in the United States. METHODS Program directors of accredited general psychiatry programs in the United States were surveyed to assess both general program details and changes in educational content, delivery, and perspectives of their respective program curricula. Data was analyzed with SPSS with 0.05 significance level. RESULTS A total of 63 program directors of 264 eligible programs were included (23.9%). We observed a dramatic shift to integrate virtual learning post-pandemic (98.5%) compared to pre-pandemic (3%). However, there was no association between these modality changes and program type [P = 0.1343]. Furthermore, changes were noted in respect to didactic content (60%), decreased rotation sites (38%), and increased telemedicine exposure (84%) with no change of wellness days (67%) or protected time (97%) and above changes had no association with program type. Interestingly, we found the use of virtual educational platforms was described as positive (59.7%) with 9 programs noting a future transition to a hybrid learning model for didactics and grand rounds. CONCLUSIONS The findings suggest that pandemic-related curriculum adaptations infiltrated all different types of psychiatry residencies and suggest a national trend to continue virtual platform integration into psychiatry didactics. However, future investigation of virtual learning outcomes are warranted.

Abstract
Objective: To systematically review the literature on the therapeutic use of amphetamine, lisdexamfetamine and methylphenidate in elderly population with and without dementia. Methods: We conducted two researches on the PubMed, Scopus and Embase using the keywords (“elderly”) AND (“amphetamine” OR “methylphenidate” OR “lisdexamfetamine”) and then (“Alzheimer” OR “dementia”) AND (“amphetamine” OR “methylphenidate” OR “lisdexamfetamine”). Results: Twenty-nine papers met all the eligibility criteria. The results are encouraging as 81.5% of the studies showed clinical improvement of the investigated condition. Conclusion: Amphetamines and methylphenidate are probably effective strategies for different conditions in the elderly population. However, further studies are needed to provide more robust evidence on efficacy, dosage and safety for this population.

Abstract
AIMS To evaluate a low-cost water quality test for at-scale drinking water safety estimation in rural India. METHODS AND RESULTS Within a longitudinal study to characterize variability in household drinking water safety in rural Maharashtra, we piloted a low-cost presence-absence (LCPA) microbial test designed to be used by volunteer residents in rural areas. In comparing the LCPA results with standard laboratory methods for enumeration of Escherichia coli, we found that LCPA tests using modified mTec media were highly sensitive in detecting drinking water of moderate risk (88% of tests were positive at E. coli counts of 11-100 CFU per 100 ml) and high risk (96% of tests were positive at E. coli counts of 101 + CFU per 100 ml). The LCPA tests demonstrated low specificity for E. coli specifically, due to concurrent detection of Klebsiella: 38% of LCPA tests were positive even when E. coli was not detected in a 100 ml sample by membrane filtration, suggesting the test would be conservative in risk estimation. We also found that 47% of participants in rural villages in India were willing to conduct tests and return results after a brief training, with 45% of active participants sending their water testing results via short message service. CONCLUSIONS Given their low cost (~US$0.50 as piloted) and open-source format, such tests may provide a compelling alternative to standard methods for rapid water quality assessments, especially in resource-limited settings. SIGNIFICANCE AND IMPACT OF THE STUDY The lack of availability of water quality data constrains efforts to monitor, evaluate and improve the safety of water and sanitation infrastructure in underserved settings. Current water testing methods are not scalable because of laboratory and cost constraints. Our findings indicate the LCPA or similar low-cost microbial tests could be useful in rapid water safety estimation, including via crowdsourcing.

Abstract
Depression and osteoporosis are 2 common comorbidities in geriatric patients. There are concerns about the deleterious effects of selective serotonin reuptake inhibitor (SSRI) antidepressant use on bone mineral density (BMD). We examined the association between SSRI use and BMD in elderly women (≥65 yr) referred to a geriatric osteoporosis clinic for bone health evaluation. Cross-sectional analyses using the general linear model were performed on data collected retrospectively from August 2010 to April 2015. A total of 250 women were seen during the study period. Of these, 140 women had complete data on BMD measurements: 22 (15.7%) used an SSRI and 118 (84.3%) did not. The 2 groups, SSRI users and SSRI nonusers, did not differ significantly across any of the covariates tested (age, ethnicity, body mass index, and past and present osteoporosis treatment medications). After adjusting for covariates, there was no difference in the BMDs at the femoral neck (p = 0.887) or the spine (p = 0.275) between the 2 groups. Similarly, no difference was seen in the T-scores between SSRI users and nonusers at the femoral neck (p = 0.924) or at the spine level (p = 0.393). Our study did not show an association between SSRI use and BMD among elderly women referred for bone health evaluation. Other studies in the literature have been inconclusive, and therefore, robust longitudinal studies are needed to further assess the interaction between SSRI use and predictors of fracture such as BMD, bone turnover markers, and genes involved in bone turnover. Until then, clinicians should closely monitor the bone health of long-term SSRI users.

Abstract
BACKGROUND Use of hypnotics or anxiolytic drugs is common and various studies have reported increased mortality with hypnotics or anxiolytic use. OBJECTIVE To consolidate the evidence on mortality risk associated with hypnotics or anxiolytic use METHODS Major databases were searched through April 2014 for studies reporting mortality risk associated with hypnotics or anxiolytics use. A pooled hazard ratio with 95% confidence interval was estimated using random-effects model. RESULTS After screening 2188 articles, 25 studies (24 cohort, 1 case-control) enrolling 2,350,093 patients with 59% females (age 18-102 years) were included in the meta-analysis. Hypnotics or anxiolytic users had 43% higher risk of mortality than non-users (hazard ratio, 1.43; 95% confidence interval, [1.12, 1.84]). Eight studies reported risk estimates for each gender category and pooled results from these studies showed increased risk of mortality among men (hazard ratio = 1.60, 95% confidence interval = [1.29,1.99]) and women (hazard ratio = 1.68, 95% confidence interval = [1.38, 2.04]). Pooled results from 10 studies showed higher mortality among benzodiazepine users compared to non-users (hazard ratio = 1.60, 95% confidence interval = [1.03, 2.49]), while pooled results from five studies showed an increased risk of mortality with Z-drugs use although the effect could not reach statistical significance (hazard ratio = 1.73, 95% confidence interval = [0.95, 3.16]). Significant heterogeneity was observed in the analyses and the quality of included studies was good. CONCLUSION This meta-analysis suggests that hypnotics or anxiolytics drugs use is associated with increased mortality and hence should be used with caution. Future studies focused on underlying mechanism of increased mortality with hypnotics or anxiolytics use are required.

Abstract
We describe the first invertebrate model of attention deficit hyperactivity disorder (ADHD) that reproduces its major features, including hyperactivity, male predominance, marked exacerbation by simple carbohydrates, reversible response to dextroamphetamine, and a "paradoxical response" to stimulants. This model may offer new insight into ADHD pathogenesis and treatment. Furthermore, these findings are of particular interest in light of the recent epidemiological evidence showing that patients with dementia have a high frequency of antecedent ADHD symptoms.

Abstract
OBJECTIVE Clinicians' attention is a precious resource, which in the current healthcare practice is consumed by the cognitive demands arising from complex patient conditions, information overload, time pressure, and the need to aggregate and synthesize information from disparate sources. The ability to organize information in ways that facilitate the generation of effective diagnostic solutions is a distinguishing characteristic of expert physicians, suggesting that automated systems that organize clinical information in a similar manner may augment physicians' decision-making capabilities. In this paper, we describe the design and evaluation of a theoretically driven cognitive support system (CSS) that assists psychiatrists in their interpretation of clinical cases. The system highlights, and provides the means to navigate to, text that is organized in accordance with a set of diagnostically and therapeutically meaningful higher-level concepts. METHODS AND MATERIALS To evaluate the interface, 16 psychiatry residents interpreted two clinical case scenarios, with and without the CSS. Think-aloud protocols captured during their interpretation of the cases were transcribed and analyzed qualitatively. In addition, the frequency and relative position of content related to key higher-level concepts in a verbal summary of the case were evaluated. In addition the transcripts from both groups were compared to an expert derived reference standard using latent semantic analysis (LSA). RESULTS Qualitative analysis showed that users of the system better attended to specific clinically important aspects of both cases when these were highlighted by the system, and revealed ways in which the system mediates hypotheses generation and evaluation. Analysis of the summary data showed differences in emphasis with and without the system. The LSA analysis suggested users of the system were more "expert-like" in their emphasis, and that cognitive support was more effective in the more complex case. CONCLUSIONS Cognitive support impacts upon clinical comprehension. This appears to be largely helpful, but may also lead to neglect of information (such as the psychosocial history) that the system does not highlight. The results have implications for the design of CSSs for clinical narratives including the role of information organization and textual embellishments for more efficient clinical case presentation and comprehension.

Abstract
Abstract
Background: Genetic diseases may display parent-of-origin effects. In such cases, the risk depends on the specific parent or origin allele. Imprinting effect is evident in autosomal dominant hereditary paraganglioma leads to tumors only if inherited from paternal germline. Cancer penetrance in mutations carriers may be determined by the parent origin of BRCA mutation.
Methods: From 2007–2010 we analyzed 1889 consecutive (136 ovarian + 1753 breast) breast (BrCa) or ovarian cancer (OvCa) patients presenting for treatment at our outpatient facility. In 130 patients with BRCA 1 or 2 mutations the parent of origin for the mutation was known. Of the 130 patients 2 had both BRCA1 and BRCA2 mutated paternally inherited and were excluded from this analysis. Of the breast cancer patients: 28 patients had paternal and 29 had maternal BRCA1 mutations, 24 had paternal and 21 had maternal BRCA 2 mutations. Of the ovarian cancer patients 6 had paternal and 10 had maternal BRCA1 mutations, 7 had paternal and 3 had maternal BRCA2 mutations. In carriers of BRCA mutations the mean age at diagnosis for ovarian cancer was 51 (range 21–70) and for breast cancer was 43 (range 24–78).
Two-sample t-test was used to compare the mean age at diagnosis in patients with BRCA 1 or 2 mutations of paternal or maternal inheritance.
For breast cancer maternal allele versus paternal allele 2-sample t-test and p-value were compared for the age at first diagnosis. For breast cancer patients BRCA1 maternal inheritance (mean+SD yrs) 45.73+11.22 versus paternal inheritance 38.04+7.14 2-sample t-test p-value p<0.0020. For breast cancer BRCA2 maternal inheritance (mean+SD yrs) 50.65+10.44 versus paternal inheritance 41.68+6.16, 2-sample t-test p-value p<0.0008.
Results: Significantly younger age at breast cancer diagnosis was observed in paternal vs. maternal inheritance of BRCA1 mutation (38 vs 46, respectively, p<0.0020) and BRCA2 mutation (42 vs 51 respectively, p<0.0008). There was no significant difference between paternal and maternal age of ovarian cancer diagnosis of BRCA1 (p<0.1415) or BRCA2 mutation (p<0.3470).
Conclusion: The restrospective nature of the study may introduce ascertainment bias. However, the breast and ovarian cancers cases in BRCA1 & 2 carriers with maternal or paternal inheritance mirror the Mendelian autosomal dominant pattern in our unselected consecutive cohort of patients. Maternal and paternal inherited BRCA alleles may not be exchangeable. Women with paternally inherited mutations in BRCA gene mutations develop breast cancer at younger age compared with women who inherit the gene mutations from their mothers. In this small sample, clear differences at age of cancer diagnosis are apparent in paternal inheritance of BRCA gene mutation. If this observation duplicates in larger cohorts results will have important implications for recommendation of surgical risk reduction in BRCA mutation carriers.

Abstract
Background: Cigarette smoking is well correlated with lung diseases such as chronic obstructive pulmonary disease. It is common among men than women in India. In addition, sedentary lifestyle is associated with less efficient pulmonary function. Effectiveness of upper body resistance training (UBRT) in improving pulmonary function is unclear. Keeping all these factors in view, this study aims to examine the effect of UBRT on pulmonary function in male sedentary smokers. Materials and Methods: This study recruited 36 sedentary male smokers, of which 30 were randomized into two groups after fulfilling eligibility criteria-an exercising experimental group (EG) (N=15) or non-exercising control group (CG) (N=15). The EG group were assigned to exercise for 4 weeks, 3 times weekly on non-consecutive days using UBRT program and breathing exercise. In the CG, only breathing exercise was given for 10 min. Both groups were equivalent in baseline characteristics. Results: The improvement in forced expiratory volume in one second (FEV1) and FEV1/forced vital capacity (FVC) values were seen significant in EG after 4 weeks of UBRT: from 3.62±0.56 to 3.96±0.51 (P=0.000) and 0.88±0.11 to 0.96±0.13 (P<0.001), respectively. But FVC did not show significant change in the EG (P=0.430). There were no significant changes in FEV1, FVC, and FEV1/FVC values in CG after 4 weeks of intervention. On intergroup comparison, significant difference was found between CG and EG for FEV1 and FEV1/FVC values. Conclusion: Four weeks of UBRT program brought about significant changes in the pulmonary function in male sedentary smokers.

Abstract
An assessment of whether to rehabilitate a tooth requiring endodontic treatment or to replace it with a dental implant can often involve a challenging and complex decision-making process. This paper reviews the literature pertaining to both treatment modalities and identifies key issues that need careful consideration in planning the most appropriate course of care in a given clinical situation. A need to appreciate advances across both disciplines is highlighted, allowing the development of effective interdisciplinary evidence-based treatment strategies to maximize treatment outcome.

Abstract
OBJECTIVES This pilot study evaluated the efficacy and safety of adjunctive topiramate compared with placebo in the treatment of patients with a diagnosis of schizoaffective disorder, bipolar type (SAD-BT). METHODS A sample of 48 adult patients with a Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) diagnosis of SAD-BT (supported by the Structured Clinical Interview for DSM-IV Axis I Disorder, Patient Edition) were randomly assigned in a 2:1 ratio (favoring topiramate) to 8 weeks of double-blind treatment with topiramate (100-400 mg/day) or placebo. Patients who had achieved a > or =20% decrease from baseline in their Positive and Negative Syndrome Scale (PANSS) total scores were given the opportunity to continue for an additional 8 weeks of double-blind treatment. The dosage of the study medicine was continued unchanged from the earlier 8-week study period. At the end of the study period, the study medicine was tapered and discontinued over a 2-week period. Primary efficacy was assessed at 8 weeks using the mean change between treatment groups of the PANSS total scores in the intent-to-treat population of randomized patients. Several secondary measures were also assessed. Safety analyses included monitoring of adverse events, vital signs, electrocardiogram (ECG) and laboratory values. RESULTS Even though both treatments reduced scores on various psychopathology rating scales, adjunctive topiramate treatment (nearly 275 mg/day) did not show increased efficacy relative to placebo on the primary outcome measure (PANSS scale) or any of the secondary outcome measures. Topiramate-treated patients lost significantly more body weight than placebo-treated patients, which led to a significant reduction in body mass index (BMI). Relative to adjunctive placebo, topiramate-treated patients experienced higher rates of paresthesia, sedation, word-finding difficulty, sleepiness, and forgetfulness, but these differences were not statistically significant. There were no clinically significant abnormalities in either the ECG or laboratory results. There were no serious adverse events in the study. Further, there was no worsening of the PANSS total scores (to > or =10% from baseline), and no significant differences between the treatments on worsening of total Montgomery-Asberg Depression Rating Scale (MADRS) scores [1/13 (7.7%) for placebo; 1/25 (4.0%) for topiramate]. CONCLUSIONS This pilot study did not support clinical efficacy for adjunctive topiramate treatment in patients with SAD-BT. There were no major safety or tolerability issues in this study. Confirming the results of other studies, topiramate-treated patients did experience greater body weight loss and reduction in BMI.

Abstract
CONTEXT A history of depression may increase risk for developing Alzheimer disease (AD) later in life. Clarifying this relation might improve understanding of risk factors for and disease mechanisms in AD. OBJECTIVE To systematically review and complete a meta-analysis on the relation of depression and AD. DATA SOURCES We conducted electronic bibliographic searches of MEDLINE, PsychLit, EMBASE, and BIOSIS using search terms sensitive to studies of etiology combined with searches on terms related to depression and AD and reviewed reference lists of articles. STUDY SELECTION Studies with data contrasting depressed vs nondepressed patients who did and did not later develop AD were included. Studies that related continuous measures of depression and cognitive status were excluded. DATA EXTRACTION Numerical data were independently extracted by 3 reviewers. They also rated studies on a scale that assessed quality indicators for observational studies. Data on the interval between observation of depression and the diagnosis of AD were collected when available. DATA SYNTHESIS Meta-analytic evaluation with random-effects models resulted in pooled odds ratios of 2.03 (95% confidence interval, 1.73-2.38) for case-control and of 1.90 (95% confidence interval, 1.55-2.33) for cohort studies. Findings of increased risk were robust to sensitivity analyses. Interval between diagnoses of depression and AD was positively related to increased risk of developing AD, suggesting that rather than a prodrome, depression may be a risk factor for AD. CONCLUSIONS A history of depression may confer an increased risk for later developing AD. This relation may reflect an independent risk factor for the disease.

Abstract
OBJECTIVES To evaluate the point prevalence of the metabolic syndrome in patients with schizoaffective disorder--bipolar type. METHODS Consenting patients who were participants in an ongoing clinical trial of adjunctive topiramate treatment for schizoaffective disorder, bipolar type were evaluated at baseline for the point prevalence of the metabolic syndrome. The criteria for the metabolic syndrome included: (a) waist circumference > 102 cm (40 inches) in males, or > 88 cm (35 inches) in females; (b) fasting serum triglyceride levels > or = 150 mg/dL; (c) fasting high density lipoproteins (HDL) cholesterol <40 mg/dL in men or <50 mg/dL in women; (d) blood pressure > or = 130/85 mmHg; and (e) fasting glucose > or = 110 mg/dL. Subjects who had at least three of these five criteria were defined as meeting criteria for the metabolic syndrome. RESULTS Thirty-six subjects (males = 15, females = 21) were evaluated, and three were excluded for missing data. Among those 33 subjects with complete data, 14 subjects (42.4%, males = 7, females = 7, African Americans = 6, Caucasians = 8) met criteria for the metabolic syndrome. Not unexpectedly, those with the metabolic syndrome were significantly more likely to be obese, and have significantly higher mean systolic and diastolic blood pressure, mean fasting triglyceride levels and larger mean waist circumferences, and significantly lower HDL cholesterol levels; and a trend toward higher fasting blood glucose levels. Furthermore, the fasting mean total cholesterol in those with the metabolic syndrome was 217 mg/dL (+/-46). CONCLUSIONS This preliminary report suggests that the point prevalence of the metabolic syndrome in patients with schizoaffective disorder appears to be higher than that reported in the general population of the USA. Targeted weight reduction and life style change strategies (increased exercise, smoking cessation, stress reduction) may provide useful interventions to decrease the morbidity and mortality that accompanies the presence of the metabolic syndrome in patients with psychiatric illnesses.

Abstract
Radiotherapy with external beam radiation or brachytherapy is an established therapeutic modality for prostate cancer. Approximately 30% of patients with localised prostate cancer relapse at the irradiated site. Secondary effects of ionising radiation (IR), for example, bowel and bladder complications, are common. Thus, the search for biological response modifiers that could potentiate the therapeutic effects of radiation and limit the occurrence of serious side effects is an important task in prostate cancer therapy. 1alpha,25-Dihydroxyvitamin D(3) (calcitriol), the active metabolite of vitamin D, and its analogues are under investigation for the treatment of several malignancies including prostate cancer. Here, we report that 1alpha,25-dihydroxyvitamin D(3) and its less calcaemic analogue 19-nor-1alpha,25-(OH)(2)D(2) (Zemplar) act synergistically with IR to inhibit the growth of the human prostate cancer cells in vitro. 1alpha,25-dihydroxyvitamin D(3) potentiated IR-induced apoptosis of LNCaP cells, and nanomolar doses of 1alpha,25-dihydroxyvitamin D(3) and 19-nor-1alpha,25-(OH)(2)D(2) showed synergistic inhibition of growth of LNCaP cells at radiobiologically relevant doses of IR (1-2 Gy). At higher doses of IR, the combination of 1alpha,25-dihydroxyvitamin D(3) and IR or 19-nor-1alpha,25-(OH)(2)D(2) and IR resulted in moderate antagonism. The synergistic effect at radiobiologically relevant doses of radiation suggests that a combination of 1alpha,25-dihydroxyvitamin D(3) or 19-nor-1alpha,25-(OH)(2)D(2) with IR could permit a reduction in the dose of radiation given clinically and thus potentially reduce treatment-related morbidity.

Abstract
BACKGROUND Quetiapine, a drug with a broad pharmacologic profile (similar to that of clozapine), may show benefits for agitation in patients with psychoses. Also, quetiapine may be superior to placebo and either equal or superior to haloperidol in treating this symptom. Available data for other second-generation antipsychotic agents show that quetiapine may have better efficacy in improving agitation compared with haloperidol. OBJECTIVE This reanalysis of a previously reported pivotal clinical trial assessed whether quetiapine or haloperidol has benefits for the treatment of hostility and agitation among patients experiencing an acute exacerbation of schizophrenia. METHODS Patients aged 18 to 65 years of either sex and any ethnicity who had a diagnosis of schizophrenia based on the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition criteria and who were experiencing an acute exacerbation were recruited into the study. A priori, data from patients assigned to 4 therapeutically effective quetiapine treatment groups (150, 300, 600, and 750 mg) in a previously reported 6-week, double-blind, placebo-controlled clinical trial were combined and compared with data from patients given haloperidol 12 mg or placebo on an agitation measure derived from the Brief Psychiatric Rating Scale (BPRS). Patients who received at least 2 weeks of treatment who had a baseline assessment and at least 1 postbaseline assessment after the 2 weeks of treatment were included. An analysis of variance with the baseline hostility score and center as covariates was used to assess treatment effects of quetiapine or haloperidol versus placebo for changes in agitation scores. A path analysis was used to separate the direct from the indirect effects (via improvements in psychoses and/or overall psychopathology) on agitation scores of quetiapine relative to haloperidol. RESULTS A total of 257 patients (193 men, 64 women) were studied. The combined quetiapine groups comprised 175 patients; the haloperidol group, 42 patients; and the placebo group, 40 patients. Quetiapine treatment reduced agitation scores significantly among patients with acute psychoses compared with placebo. A slight reduction in agitation scores was found when haloperidol treatment was compared with placebo, but this difference was not statistically significant. Compared with haloperidol, quetiapine treatment had a direct and significant effect on agitation that was independent of the improvement in psychotic symptoms. CONCLUSIONS The data in this study suggest that quetiapine treatment has benefits for hostility and agitation among patients experiencing an acute exacerbation of schizophrenia. Furthermore, the path analysis indicated that, relative to haloperidol, quetiapine appeared to have direct effects on agitation that were independent of improvements in psychoses or overall psychopathology, as assessed by the BPRS.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common childhood autoimmune rheumatic disease and like rheumatoid arthritis (RA), it is characterized by inflammation and the progressive destruction of joints. In RA, cathepsins as proteinases play a major role in destroying synovial tissue and cartilage matrix. So far no data on cathepsin expression in pannus tissue of HA patients exist. The aim of this study was to characterize the expression levels of cathepsins B, D, H, and L in HA and to compare them with those in RA. Synovectomy tissue from 16 HA and 12 RA patients was investigated for cathepsin expression levels by Western blot analysis. Expression of cathepsins B, D and L was on comparable levels in the synovectomy tissue of HA and RA patients. The following graduation of expression was determined: cathepsin D > cathepsin L > cathepsin B. Cathepsin H was neither found to be expressed in HA nor in RA patients. The expression levels of cathepsins in pannus tissue showed no clear difference between patients with systemic JIA and patients with monoarticular JIA. In summary, the comparable expression of cathepsins B, D and L in RA and JIA synovectomy tissue suggests that they may play a similarly important role in destroying synovial tissue and cartilage matrix in the course of HA and RA.

Abstract
Food impaction occasionally occurs in interproximal sites even though the contacts are tight. In this study of 14 patients with food impaction involving tight contacts, the lack of adequate food escape grooves was common to all 14 sites. Uneven marginal ridges and prominent opposing cusps were less common and, together, made up slightly more than half of the contact sites. An occlusal adjustment technique to create adequate food escape grooves, as well as reduce prominent opposing cusps and correct uneven marginal ridges, completely eliminated food impaction in all but one site. This site achieved an 80% reduction in food impaction. Based on the results of this retrospective study, the lack of adequate food escape groves in teeth adjacent to a contact point manifesting food impaction appears to be the primary factor. Creating food escape grooves adjacent to the marginal ridges eliminates, or nearly eliminates, food impaction in tight contact sites.

Abstract
Obesity and associated medical conditions may have an impact on morbidity and even mortality in patients with psychiatric disorders. The authors present the results of a survey of the prevalence of obesity and selected medical conditions among 420 consecutively admitted psychiatric inpatients at a long-stay facility and compare these data with those reported in the literature. Female psychiatric subjects had considerably higher rates of being either overweight or obese (69%) as compared to women in the general U.S. population (51%). Male psychiatric subjects did not differ significantly from their counterparts in the general population in being overweight or obese (nearly 55%). The majority of psychiatric subjects with essential hypertension, diabetes mellitus, dyslipidemias, cardiovascular disease, or sleep apnea were either overweight or obese (72%-87%). In this cross-sectional study, no associations could be deduced between psychotropic drug classes and specific medical conditions. No specific psychiatric diagnostic category was associated with a significantly greater prevalence of any specific medical condition, except that subjects with schizoaffective disorder appeared to have a higher prevalence of type II diabetes mellitus (11.6%). Subjects with predominant substance or alcohol abuse or dependence disorders had a lower prevalence of obesity and associated medical conditions.Obesity-either independently or additively along with a sedentary lifestyle, unhealthy dietary habits, and nicotine dependence-may have a serious impact on coexisting medical comorbidity in psychiatric patients. Judicious monitoring for obesity and rapid pharmacological and nonpharmacological intervention, where appropriate, by concerned clinicians may improve several coexisting medical conditions in psychiatric patients and thereby improve patients' overall quality of life.

Abstract
OBJECTIVE To study the efficacy of combination therapy with etanercept and methotrexate in patients with refractory juvenile idiopathic arthritis. METHODS Seven children with active juvenile idiopathic arthritis refractory to at least combination therapy with methotrexate and sulfasalazine or cyclosporin A were studied. Concomitant treatment, consisting of non-steroidal drugs, corticosteroids, and methotrexate, remained unchanged. RESULTS Six patients continued the treatment for at least 24 weeks. In the child with systemic arthritis, etanercept was stopped because of persisting spiking fever, joint pain, and rash. In the remaining children an immediate significant decrease in joint pain (p<0.05), disappearance of morning stiffness, and regression of joint swelling (p<0.05) were observed. Improvement was apparent after two injections. An immediate significant (p<0.05) decrease in erythrocyte sedimentation rate, C reactive protein, and interleukin 6 was observed. Side effects consisted of mild reactions at the injection site in two children. CONCLUSIONS In this observational study, etanercept in combination with methotrexate was well tolerated and highly effective in treating juvenile polyarthritis but not in the patient with systemic arthritis. Combination treatment appears to be feasible in terms of toxicity and may enhance efficiency.

Abstract
OBJECTIVE Early detection of prostate cancer has become a matter of vital importance in modern societies. Ultrasound guided transrectal biopsy is the current standard urological procedure to detect prostate cancer. In this study our intention was to confirm the high tolerance and low complication rate of this procedure, facts already established in urologists' minds. MATERIAL AND METHODS In order to evaluate the morbidity as well as the acceptance of the procedure, we investigated 120 patients who underwent ultrasound guided transrectal biopsies of the prostate, in our department from September 1995 to January 1996. All patients at each biopsy underwent 6 needle passes and took periprocedural antibiotic therapy. Alongside with recording the periprocedural side effects of this method patients answered a questionnaire in order to evaluate the pain they experienced by this procedure. RESULTS Twenty patients were found to have prostate cancer at various stages. All patients tolerated well the whole procedure. Pain was the most common complaint among patients. Several complications were recorded; the most common of all was haematuria. Only two patients required admission to hospital because they developed fever after the procedure. CONCLUSION Ultrasound guided transrectal biopsy of the prostate is a well-tolerated and effective method for obtaining multiple biopsy specimens from the prostate with low incidence of serious complications. Its is also accurate enough, allowing its use in everyday urology, as a diagnostic procedure.

Abstract
Implant-supported restorations have become very popular in the management of the partially or completely edentulous patient. Success depends on attentive treatment planning and coordinated teamwork between the surgeon and the restoring dentist. Implants placed in the anterior maxilla require special attention due to esthetic considerations. This article describes the management of a severely resorbed anterior maxilla using principles of guided bone regeneration followed by implant-supported restorations. This case illustrates some of the problems that can arise during the course of treatment.

Abstract
Converging lines of evidence implicate the beta-amyloid peptide (Ass) as causative in Alzheimer's disease. We describe a novel class of compounds that reduce A beta production by functionally inhibiting gamma-secretase, the activity responsible for the carboxy-terminal cleavage required for A beta production. These molecules are active in both 293 HEK cells and neuronal cultures, and exert their effect upon A beta production without affecting protein secretion, most notably in the secreted forms of the amyloid precursor protein (APP). Oral administration of one of these compounds, N-[N-(3,5-difluorophenacetyl)-L-alanyl]-S-phenylglycine t-butyl ester, to mice transgenic for human APP(V717F) reduces brain levels of Ass in a dose-dependent manner within 3 h. These studies represent the first demonstration of a reduction of brain A beta in vivo. Development of such novel functional gamma-secretase inhibitors will enable a clinical examination of the A beta hypothesis that Ass peptide drives the neuropathology observed in Alzheimer's disease.
