Succinic anhydride (SAD) modified microcrystalline cellulose (MCC) films was prepared and used for the controlled release of the drug domperidone (dom). The morphology and chemical structure of the modified materials were characterized by SEM, FTIR, XRD and TG/DSC techniques. The physical properties, such as water uptake and swelling, light barrier properties, mechanical testing, in vitro degradation behavior, have been investigated. Results showed that the modified cellulose membranes exhibited good anti-UV properties, higher water uptake values, improved mechanical capacity and anti-biodegradability...

Seasonal affective disorder (SAD), beyond mood changes, is characterized by alterations in daily rhythms of behavior and physiology. The pathophysiological conditions of SAD involve changes in day length and its first-line treatment is bright light therapy. Animal models using nocturnal rodents have been studied to elucidate the neurobiological mechanisms of depression, but might be ill suited to study the therapeutic effects of light in SAD since they exhibit light-aversive responses. Here Arvicanthis ansorgei, a diurnal rodent, was used to determine behavioral, molecular and brain dopamine changes in response to exposure to a winter-like photoperiod consisting of a light-dark cycle with 8 h of light, under diminished light intensity, and 16 h of darkness...

BACKGROUND: Social anxiety disorder (SAD) (formerly called social phobia) is among the most common mental health diagnoses among older adults; however, the research on late-life social anxiety is scarce. A limited number of studies have examined the assessment and diagnosis of social anxiety disorder in this population, and there are few social anxiety measures that are validated for use with older adults. One such measure, the Older Adult Social Evaluative Scale (OASES), was designed for use with this population, but until now has lacked validation against a gold-standard diagnostic interview...

BACKGROUND: Cognitive decline is an important complication of joint replacement surgeries in senior people. METHODS: We determined incidence rates of dementia diagnosis following endoprosthetic joint replacement surgery (upper and lower extremities). The observation period covered up to 28 quarters using German claims data comprising 154,604 cases 65 years and older. Effects were controlled for cerebrovascular and vascular risk factors, age, sex, the presence of a diagnosis of delirium, and regular prescription of sedative or analgesic drugs (SAD)...

We examined (1) differences between controls and patients with social anxiety disorder (SAD) in emotional clarity and attention to emotions; (2) changes in emotional clarity and attention to emotions associated with cognitive-behavioral group therapy (CBGT), mindfulness-based stress reduction (MBSR), or a waitlist (WL) condition; and (3) whether emotional clarity and attention to emotions moderated changes in social anxiety across treatment. Participants were healthy controls (n = 37) and patients with SAD (n = 108) who were assigned to CBGT, MBSR, or WL in a randomized controlled trial...

Modeling the relationship between drug concentrations and heart rate corrected QT interval (QTc) change from baseline (C-∆QTc), based on Phase I single ascending dose (SAD) or multiple ascending dose (MAD) studies, has been proposed as an alternative to thorough QT studies (TQT), in assessing drug-induced QT prolongation risk. The present analysis used clinical SAD, MAD and TQT study data of an experimental compound, AZD5672, to evaluate the performance of: (i) three computational platforms (linear mixed-effects modeling implemented via PROC MIXED in SAS, as well as in R using LME4 package and linear quantile mixed models (LQMM) implemented via LQMM package; (ii) different model structures with and without treatment- or time-specific intercepts; and (iii) three methods for calculating the confidence interval (CI) of QTc prolongation (analytical and bootstrap methods with fixed or varied geometric mean concentrations)...

Objective: Problems in emotion processing potentially contribute to the development and maintenance of chronic pain. Theories focusing on attentional processing have suggested that dysfunctional attention deployment toward emotional information, i.e., attentional biases for negative emotions, might entail one potential developmental and/or maintenance factor of chronic pain. Methods: We assessed self-reported alexithymia, attentional orienting to and maintenance on emotional stimuli using eye tracking in 17 patients with chronic pain disorder (CP) and two age- and sex-matched control groups, 17 healthy individuals (HC) and 17 individuals who were matched to CP according to depressive symptoms (DC)...

Background: Depressed populations demonstrate a greater tendency to have negative interpretations on ambiguous situations. Cognitive theories concerning depression proposed that such a negative bias plays an important role in developing and maintaining depression. There is now fairly consistent evidence arising from different stimuli and assessment methods that depression is featured by such a bias. The current study aimed to explore the neural signatures associated with the interpretation bias in the elderly with depressive symptoms confronted with different facial expressions using event-related brain potentials (ERPs)...

BACKGROUND: I review the historical antecedents of the two key features of the bereavement exclusion (BE) for major depression (MD) criteria initially proposed in DSM-III: (i) a context-dependent approach to the evaluation of MD which required that the diagnosis be given only when course, symptoms and signs are 'out of proportion' to experienced adversities, and (ii) bereavement is the sole adversity for which this context-dependent approach should be utilized. METHODS: A review of 49 textbook and review articles on depression or melancholia published 1880-1960...

BACKGROUND: Hamm is an Arabic word that is used to express suffering. Idioms of distress are communicated differently in different contexts and cultures. Understanding idioms of distress and symptoms can help in diagnosis and lead to socioculturally sensitive health care. METHODS: In this qualitative study, we did semi-structured interviews with men and women of all age groups. Questions focused on the definition, causes, and consequences of Hamm. Responses were analysed by reading and re-reading interview transcripts until themes and subthemes emerged...

This qualitative study assessed psychosocial concerns that rural women with HIV who had multiple psychosocial vulnerabilities were able to express and communicate during a mobile phone intervention delivered by nurses. The study is part of a pilot randomised controlled trial of an mHealth self-care intervention by nurses for women living with HIV in rural India. For the trial, 60 women were randomised to receive the mHealth intervention. All calls were recorded and call logs were maintained. Call logs of 59 women based on 1186 calls were scanned for psychosocial themes...

PURPOSE: Subacromial impingement syndrome (SIS) is associated with low self-reported shoulder function, impairments in shoulder strength and range of motion (ROM), and pain. It is not known how the symptomatology associated with SIS is reflected in the choice of treatment. This study compares self-reported shoulder function, shoulder strength, ROM, and pain in patients with SIS considered candidates and non-candidates for subacromial decompression (SAD). METHOD: Self-reported shoulder function (Q-DASH and SPADI), maximum isometric muscle strength in shoulder abduction (Abd-strength) and external rotation (ER-strength), active abduction ROM (Abd-ROM) and passive internal rotation ROM (IR-ROM) were measured in a consecutive cohort of patients with SIS referred to an orthopedic outpatient clinic...

The current evidence regarding the indication, advantages and risks of red blood cell transfusion (RBCT) for preterm infants is discussed. This is an important area in Neonatology to be examined given that 90% of extremely low birth weight infants receive RBCT and many controversies remain regarding when to transfuse and the risks of RBCT. The various treatment thresholds and guidelines used are presented and we compare the short-term clinical benefits of liberal and restrictive RBCT in preterm infants; the majority of these are equivocal and sadly long-term outcome data is limited...

BACKGROUND: Deficits in emotional prosody processing have been observed in bipolar disorder (BD). While recent neural studies have explored impaired processing of facial expressions, little is known about deficits in emotional speech processing, or the specific stages of processing at which they occur. This study examined if pre-attentive detection and attention to emotional speech is impaired in BD, relative to healthy individuals. METHODS: The EEG data was collected from 14 individuals with BD and 14 healthy control (HC) participants while the auditory stimuli was presented via a passive three-stimulus oddball sequence which included emotionally (neutral, happy, sad) spoken syllables and acoustically matched nonvocal tones...

BACKGROUND: Many patients reporting musculoskeletal pain present to Primary Care Physiotherapy with costly comorbid overlapping complaints that remain medically unexplained. These subjective health complaints (SHC) incorporate coexisting multi-site musculoskeletal pain and varied non-musculoskeletal complaints (e.g. anxiety, tiredness). The role of these non-musculoskeletal complaints is acknowledged in spinal musculoskeletal disorders, but less so for peripheral musculoskeletal disorders...

Using a national sample of youth from the U.S., this paper examines incidents of bias-based harassment by peers that include language about victims' perceived sexual orientation, race/ethnicity, religion, weight or height, or intelligence. Telephone interviews were conducted with youth who were 10-20 years old (n = 791). One in six youth (17%) reported at least one experience with bias-based harassment in the past year. Bias language was a part of over half (52%) of all harassment incidents experienced by youth...

Depression risk genes in combination with childhood events have been associated with biased processing as an intermediate phenotype for depression. The aim of the present conceptual replication study was to investigate the role of biased automatic approach-avoidance tendencies as a candidate intermediate phenotype for depression, in the context of genes (5-HTTLPR polymorphism) and childhood trauma. A naturalistic remitted depressed patients sample (N = 209) performed an Approach-Avoidance Task (AAT) with facial expressions (angry, sad, happy and neutral)...
