'Getting control of Corona takes many angles': COVID-19 vaccine knowledge, attitudes and beliefs among refugee/immigrant/migrant communities in four US cities.

The objectives of the study were to (i) document refugee, immigrant and migrant (RIM) communities' knowledge, attitudes and beliefs (KABs) related to the Coronavirus disease (COVID-19) vaccine and (ii) identify best practices for developing and disseminating culturally and linguistically responsive health messaging addressing those KABs. Thirteen online focus groups (OFGs) in 10 languages were conducted. Each OFG was conducted in the participants' native language. OFGs were recorded, transcribed, translated and uploaded to qualitative software for coding. A thematic analysis was conducted. Results suggest that while there was some variation between different language groups (e.g. whether religious leaders were seen as trusted sources of information about COVID), there were also important commonalities. Most language groups (i) alluded to hearing about or having gaps in knowledge about COVID-19/the COVID-19 vaccine, (ii) reported hearing negative or conflicting stories about the vaccine and (iii) shared concerns about the negative side effects of the vaccine. There continues to be a need for health messaging in RIM communities that is culturally and linguistically concordant and follows health literacy guidelines. Message content about the COVID-19 vaccine should focus on vaccine importance, effectiveness and safety, should be multimodal and should be primarily delivered by healthcare professionals and community members who have already been vaccinated.

PARPi after PARPi in epithelial ovarian cancer.

The objective of this study was to describe the treatment experience of patients with recurrent epithelial ovarian cancer who are retreated with an inhibitor of poly(ADP-ribose)-polymerase (PARPi). We conducted a multi-institutional, retrospective review of ovarian cancer patients who received ≥2 lines of therapy containing a PARPi. Demographic, clinical, and pathological data were analyzed with descriptive statistics. Twenty-two patients were identified. For initial PARPi (PARPi1), 12 patients (54.5%) received veliparib, 7 (31.8%) olaparib and 3 (13.6%) rucaparib resulting in 10 patients who had no evidence of disease at the completion of therapy (NED), 3 partial responses (PR), 4 stable disease (SD), and 3 progressive disease (PD). (All 10 CRs involved veliparib given in conjunction with cytotoxic chemotherapy). PARPi1 was used as maintenance in 2 patients. PARPi1 was discontinued because planned number of cycles was reached (n = 10), progression (n = 8), toxicity (n = 2), other (n = 2). For second PARPi (PARPi2), 10 patients (45.4%) received niraparib, 6 (27.3%) olaparib, and 6 (27.3%) rucaparib resulting in 3 PR, 13 SD, and 3 PD. PARPi2 was used as maintenance in 3 patients. The 3 patients who experienced a PR to PARPi2 had a BRCA mutation and were NED following PARPi1. PARPi2 was discontinued because of progression (n = 13), toxicity (n = 6), other (n = 2). One patient currently remains on PARPi2. Toxicity after PARPi1 was not associated with toxicity from PARPi2 (p > 0.05). With 3 approved PARPi for different indications including frontline and recurrence, the opportunity to reuse PARPi has increased. Characterizing those who should be re-challenged is an important initiative moving forward.

Regulatory T cells confer a circadian signature on inflammatory arthritis.

The circadian clock is an intrinsic oscillator that imparts 24 h rhythms on immunity. This clock drives rhythmic repression of inflammatory arthritis during the night in mice, but mechanisms underlying this effect are not clear. Here we show that the amplitude of intrinsic oscillators within macrophages and neutrophils is limited by the chronic inflammatory environment, suggesting that rhythms in inflammatory mediators might not be a direct consequence of intrinsic clocks. Anti-inflammatory regulatory T (Treg) cells within the joints show diurnal variation, with numbers peaking during the nadir of inflammation. Furthermore, the anti-inflammatory action of Treg cells on innate immune cells contributes to the night-time repression of inflammation. Treg cells do not seem to have intrinsic circadian oscillators, suggesting that rhythmic function might be a consequence of external signals. These data support a model in which non-rhythmic Treg cells are driven to rhythmic activity by systemic signals to confer a circadian signature to chronic arthritis.

Trials comparing alternative weaning modes and discontinuation assessments.

We identified 16 randomized controlled trials (RCTs) of methods for weaning patients from mechanical ventilation, 8 of which were trials of discontinuation assessment strategies, 5 of which were trials of stepwise reduction in mechanical ventilatory support, and 3 of which were trials comparing alternative ventilation modes for weaning periods lasting < 48 h. We found that different thresholds for deciding when a patient is ready for a trial of spontaneous breathing, different criteria for a successful trial, and different thresholds for extubation may overwhelm the impact of alternative ventilation strategies. Nevertheless, the results of these studies suggest the possibility that multiple daily T-piece weaning or pressure support may be superior to synchronized intermittent mandatory ventilation. Other RCTs suggest that early extubation with the back-up institution of noninvasive positive-pressure ventilation as needed may be a useful strategy in selected patients.

Trials comparing early vs late extubation following cardiovascular surgery.

We identified 10 randomized trials that compared alternative management approaches to patient care during and following cardiovascular surgery. One overall strategy involved a modification of anesthesia, in particular, a reduction in the dosage of fentanyl and benzodiazepine or the substitution of fentanyl for propofol (five randomized controlled trials [RCTs]). Pooled results show a shorter duration of ventilation (7 h) and a shorter duration of hospital stay (approximately 1 day) associated with lower anesthetic doses. The second strategy involved early vs late extubation once patients were admitted to the ICU (five RCTs). Pooled results show a shorter duration of ventilation (13 h) and a shorter duration of ICU stay (half a day) associated with early extubation. An additional 8 nonrandomized trials had findings that were consistent with the 10 RCTs. Reintubation, complications, and mortality rates were too low to draw conclusions about these outcomes. Overall, these studies indicate that anesthetic, sedation, and early-extubation strategies in selected cardiac surgery patients are associated with a shorter duration of mechanical ventilation and shorter lengths of ICU and hospital stays.

Influences of aquatic plants on the fate of the pyrethroid insecticide lambda-cyhalothrin in aquatic environments.

Aquatic exposure assessments for pesticides are generally based on laboratory studies performed in water alone or water sediment systems. Although aquatic macrophytes, which include a variety of bryophytes, macroalgae, and angiosperms, can be a significant component of many aquatic ecosystems, their impact on pesticide fate is generally not included in exposure assessments. To investigate the influence of aquatic plants on the fate and behavior of the pyrethroid insecticide lambda (lambda)-cyhalothrin, two laboratory experiments (to assess adsorption and degradation) and an indoor microcosm study (to assess fate under semirealistic conditions) were conducted. In the laboratory studies, adsorption to macrophytes was extensive and essentially irreversible, and degradation occurred rapidly by cleavage of the ester bond. In the indoor microcosm, which contained water, sediment, and macrophytes from a pond, degradation was also rapid, with DT50 and DT90 values of less than 3 and 19 h, respectively, for dissipation from the water column and of less than 3 and 56 h, respectively, for the whole system. For adsorptive and readily degraded pesticides like lambda-cyhalothrin, we conclude that macrophytes have considerable influence on fate and behavior in surface waters.

Selective mutism: how a successful speech and language assessment really is possible.

A speech and language assessment of children with selective mutism is often difficult because these children are silent in most situations. In Australia, a study was designed to assess the children in their homes, the place where they usually speak. Five children who met the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association 1994) criteria for selective mutism participated in the study. Assessment included audio-taping extracts of the children's conversations with members of their family and the administration of a number of standardised speech and language tests. The study found that four of the five children had a communication disorder. This paper outlines these communication disorders and describes how a successful speech and language assessment of children with selective mutism is possible.

Home-based multisystemic therapy as an alternative to the hospitalization of youths in psychiatric crisis: clinical outcomes.

OBJECTIVE: The primary purpose of this study was to determine whether multisystemic therapy (MST), modified for use with youths presenting psychiatric emergencies, can serve as a clinically viable alternative to inpatient psychiatric hospitalization. METHOD: One hundred sixteen children and adolescents approved for emergency psychiatric hospitalization were randomly assigned to home-based MST or inpatient hospitalization. Assessments examining symptomatology, antisocial behavior, self-esteem, family relations, peer relations, school attendance, and consumer satisfaction were conducted at 3 times: within 24 hours of recruitment into the project, shortly after the hospitalized youth was released from the hospital (1-2 weeks after recruitment), and at the completion of MST home-based services (average of 4 months postrecruitment). RESULTS: MST was more effective than emergency hospitalization at decreasing youths' externalizing symptoms and improving their family functioning and school attendance. Hospitalization was more effective than MST at improving youths' self-esteem. Consumer satisfaction scores were higher in the MST condition. CONCLUSIONS: The findings support the view that an intensive, well-specified, and empirically supported treatment model, with judicious access to placement, can effectively serve as a family- and community-based alternative to the emergency psychiatric hospitalization of children and adolescents.

Australian speech pathologists' views of what professional practices lead to successful outcomes of therapy.

The relative importance attributed to factors perceived by speech pathologists as contributing to successful levels of therapeutic outcomes were addressed in a survey of 372 practicing therapists in Australia. The survey consisted of 42 items derived from interviews with a sample of ten speech pathologists in Sydney. Therapists were asked to rate the importance of each item on a seven-point scale ranging from "not at all important" to "critically important." The findings indicate that the most important ingredients of successful therapy incorporate a mix of support and therapeutic activity outside the clinic; the clinicians' organizational skills and involvement in conducting therapy and their use of techniques; the positive therapeutic relationship between clinician and client; and, finally, the client's attitude to therapy. These findings suggest that speech pathologists, like other allied health professionals, endorse a humanistic or holistic approach to health care. The results provide insights into the practices that should be addressed and fostered in undergraduate speech pathology programs.

Efficacy of intravenous granisetron to control nausea and vomiting during multiple cycles of cisplatin-based chemotherapy.

The safety and efficacy of granisetron (10 micrograms/kg and 40 micrograms/kg) were evaluated during a second (n = 393) and third (n = 200) cycle of chemotherapy in this multicenter, double-blind, randomized, parallel-group study. Granisetron was administered as a single intravenous dose before the start of cisplatin chemotherapy (> or = 60 mg/m2). Total control (no vomiting, no retching, no nausea, and no use of antiemetic rescue medication) after the first 24 hr following chemotherapy was achieved in 40% and 49% of patients in Cycles 2 and 3, respectively, for the 10 micrograms/kg group, and in 42% and 38% of patients in Cycles 2 and 3, respectively, for the 40 micrograms/kg group. Both dose levels of granisetron were well tolerated. The results demonstrate comparable efficacy between the 10 micrograms/kg and 40 micrograms/kg doses of granisetron in preventing nausea and vomiting during repeat cycles of high-dose cisplatin-based chemotherapy. The results of this study show that granisetron 10 micrograms/kg is safe and well tolerated, and remains effective with repeat cycle use.

Analysing discourse in the traumatic brain injury population: telephone interactions with different communication partners.

A range of discourse analyses are effective in identifying features which are aberrant following traumatic brain injury (TBI). We examined the exchanges of five traumatically brain-injured subjects and five matched controls across four speaking situations which included speaking to a therapist, to the bus timetable information service, to the police, and to their mothers on the telephone. Transcripts were analysed using the exchange structure analysis of systemic functional grammar. This analysis provided an indication of information giving (K1 moves per minute); information requesting and receiving (K2 moves per minute) and the amount of negotiation that was needed for the messages to be conveyed (dynamic moves per minute). Results indicated that the TBI subjects performed differently across the four conditions, and were differentiated from the matched controls on a number of measures. The role of different communication partners is also addressed. Communication partners were noted to interact differently with TBI subjects when compared with controls. This included increased information-giving to control subjects; more requests for information by police from TBI subjects and a greater use of dynamic moves by therapists with controls. The potential of exchange structure analysis is discussed as a useful way of examining the discourse of TBI subjects and their communication partners. Exchange structure analysis highlighted the dynamic nature of information exchange and the subtle ways speakers responded to familiarity and power imbalance in social interaction. This study has implications for family and community education regarding communication with people with TBI.

A new perspective on the relationship between communication impairment and disempowerment following head injury in information exchanges.

Communication disorders following closed head injury (CHI) have been described in terms of the impairments that affect the individual's ability to produce words, sentences and discourse. Rather than focusing on impairments, this paper examines the disability experienced by one CHI subject. Comparison is made between M. R., who has sustained a severe CHI, and his brother, S. R. during four telephone calls to their mother, a therapist, the police and the bus timetable information service, using exchange structure analysis. Results indicated that social distance between communication partners, and the nature of the interaction, affected the language choices made by both subjects. The communication partner was found to have a profound impact on the way each subject was able to negotiate each interaction. Results are discussed in terms of the ways in which therapists and society in general view disability and how this shapes social encounters, which in turn affects the outcomes which are made possible for people with CHI.

The effect of sampling condition on children's productions of consonant clusters.

An investigation was conducted to compare the effects of single word and connected speech sampling conditions on the production of consonant clusters. Speech samples were obtained from 40 children with speech sound impairments who were aged 3 years: 6 months to 5 years. The children's productions of 36 commonly occurring consonant clusters were compared across the two sampling conditions. Overall children's productions were more similar than different. Differences between the sampling conditions were apparent for three of the eight phonological processes studied, namely, cluster reduction, final consonant deletion, and epenthesis. Of 12 fine phonetic variations, only aspirated stops showed a significant difference between the sampling conditions. There was a wide range of individual variation.

The Tridimensional Personality Questionnaire in eating disorder patients.

The Tridimensional Personality Questionnaire (TPQ) was developed to measure a variety of personality variants on three biosocial dimensions, harm avoidance (HA), novelty seeking (NS), and reward dependence (RD), which are thought to be related to serotonin (5-HT), dopamine (DA), and norepinephrine (NE) function, respectively. Patients with eating disorders have been reported to have abnormalities in all of these systems, as well as personality variants described by these dimensions. We therefore administered the TPQ to 147 patients with DSM-III-R defined eating disorders (110 bulimia nervosa [BN], 27 with anorexia nervosa [AN], and 10 with BN+AN) and compared their scores to those of 350 female controls. When significant, post hoc Bonferroni t tests were performed using alpha = 0.05. All subtypes of eating disorder patients scored significantly higher on HA than controls (p < or = .0001, analysis of variance. Only patients with BN (+/- AN) had significantly higher degrees of NS (p < or = .0001), particularly on the impulsiveness subscale (NS2), although this may, in part, be due to age. No significant differences in total RD were found, although BN patients scored lower on RD3 (attachment vs. detachment) and higher on RD4 (dependence vs. independence) than controls. In addition, AN patients had significantly higher RD2 (persistence vs. irresoluteness) subscale scores. These data support a theory of 5-HT dysregulation in both types of eating disorders and suggest that further research be done on the role of DA and NE in BN.

Prospective study of the electrocardiographic effects of imipramine in children.

Because imipramine and desipramine have been implicated in sudden death in children, noninvasive electrophysiologic data were accumulated in 25 patients. Two children were excluded on the basis of resting electrocardiographic and Holter abnormalities. The remaining 23 patients received imipramine to a maximum dose of 5 mg/kg or a serum level of 150 to 250 ng/ml. Consistent but clinically insignificant resting electrocardiographic changes occurred during treatment. Ambulatory electrocardiographic monitoring may be useful when one is assessing the cardiovascular risks of imipramine therapy.

The effects of preblending time on physical and textural properties of coarse ground sausages.

The effects of preblending storage time on physical and textural properties of coarse ground sausages were characterized. Raw materials (pork, beef) were preblended at 0-2°C and held for 0, 4, 8, 12, 16, 48, 96, 144, 196 or 240 h just prior to manufacture into Polish sausages. Expressible moisture (EM), raw batter stability, processing yield (PY), Instron compression (CO) and protein solubilization (SEM micrographs) increased from 0 to 16 h. No differences were observed for EM, PY and CO and in SEM micrographs for the 48-240 h interval. The effects of storage of preblends on sausage physical and textural properties (raw batter stability, yield, cohesiveness, SEM micrographs) occurred rapidly (0-16h), reached a maximum and either remained constant or diminished as storage time increased from 48 to 240 h.

The Iowa Articulation Norms Project and its Nebraska replication.

The purpose of the Iowa Articulation Norms Project and its Nebraska replication was to provide normative information about speech sound acquisition in these two states. An assessment instrument consisting of photographs and a checklist form for narrow phonetic transcription was administered by school-based speech-language pathologists to stratified samples of children in the age range 3-9 years. The resulting data were not influenced by the demographic variables of population density (rural/urban), SES (based on parental education), or state of residence (Iowa/Nebraska); however, sex of the child exerted a significant influence in some of the preschool age groups. The criteria used to determine acceptability of a production appeared to influence outcomes for some speech sounds. Acquisition curves were plotted for individual phoneme targets or groups of targets. These curves were used to develop recommended ages of acquisition for the tested speech sounds, with recommendations based generally on a 90% level of acquisition. Special considerations were required for the phonemes /ng s z/.

Mouse antisera specific for desmosomal adhesion molecules of suprabasal skin cells, meninges, and meningioma.

Mouse polyclonal antisera were raised to the Mr 130,000 and Mr 115,000 cell surface glycoproteins, desmocollins, of desmosomes from bovine nasal epithelium. Immunoblotting confirmed that the antisera were specific for the desmocollins. An immunofluorescence study showed that the antisera distinguished between the basal and suprabasal layers of bovine and human epidermis. The antibodies reacted with cultured keratinocytes only after calcium-induced stratification. In epidermis, therefore, there appears to be a difference between the desmocollins of basal and suprabasal cells that may be important in relation to epidermal differentiation. Previous work has shown that polyclonal antisera raised in other animals (guinea pigs and rabbits) against desmocollins, as well as against other desmosomal components, react with all desmosome-containing epithelia. In contrast, an immunofluorescence survey of bovine, rat, and human tissues showed that the present mouse antisera stained only suprabasal skin cells and the arachnoid layer of the meninges, demonstrating that these have common determinants that distinguished their desmocollins from those of all other tissues. The antibodies also stained 11 of 12 meningiomas and, therefore, may be useful as a marker not only for the diagnosis of these tumors but also for investigation of their histogenesis.
