Ultrasound as visual feedback in speech habilitation: Exploring consultative use in rural British Columbia,Canada

Ultrasound has shown promise as a visual feedback tool in speech therapy. Rural clients, however, often have minimal access to new technologies. The purpose of the current study was to evaluate consultative treatment using ultrasound in rural communities. Two speech‐language pathologists (SLPs) trained in ultrasound use provided consultation with ultrasound in rural British Columbia to 13 school‐aged children with residual speech impairments. Local SLPs provided treatment without ultrasound before and after the consultation. Speech samples were transcribed phonetically by independent trained listeners. Eleven children showed greater gains in production of the principal target // after the ultrasound consultation. Four of the seven participants who received more consultation time with ultrasound showed greatest improvement. Individual client factors also affected outcomes. The current study was a quasi‐experimental clinic‐based study. Larger, controlled experimental studies are needed to provide ultimate evaluation of the consultative use of ultrasound in speech therapy.

The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data.

Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test () in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study.

The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work.

The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.     

“It’s both a strength and a drawback.” How therapists’ personal qualities are experienced in their professional work

ABSTRACT

Objective: The aim of this study was to gain knowledge about how the integration of personal and professional experiences affects therapeutic work. Method: Therapists (N?=?14) who had been recommended by their leaders at their individual workplaces were interviewed twice with semi-structured qualitative interviews, which were then subjected to thematic and Interpretative Phenomenological Analysis. Results: All the therapists in the sample described their personal qualities as an experienced tension between their personal strengths and vulnerabilities in the therapeutic setting. This tension came to expression through four subordinate themes: (a) The tension between perceiving oneself as a helper while dealing with one’s own needs for attention and care; (b) The tension between the ability for embodied listening to the patient while tuning into oneself; (c) The tension between staying present while handling aggression and rejection from clients; and (d) The tension in striving for a constructive balance between closeness and distance. Conclusion: The results point to ways in which the personal selves of the therapists may affect their professional role performance. Drawing upon previous research and literature on the topic, the paper discusses how therapists’ personal qualities are experienced as affecting their work and suggests several implications for psychotherapy training and practice.     

Investigating the human immunodeficiency virus type 1-infected monocyte-derived macrophage secretome

Mononuclear phagocytes (bone marrow monocyte-derived macrophages, alveolar macrophages, perivascular macrophages, and microglia) are reservoirs and vehicles of dissemination for the human immunodeficiency virus type-1 (HIV-1). How virus alters mononuclear phagocyte immunoregulatory activities to complete its life cycle and influence disease is incompletely understood. In attempts to better understanding the influence of virus on macrophage functions, we used one-dimensional electrophoresis, and liquid chromatography tandem mass spectrometry to analyze the secretome of HIV-1-infected human monocyte-derived macrophages. We identified 110 proteins in culture supernatants of control (uninfected) and virus-infected cells. Differentially expressed cytoskeletal, enzymes, redox, and immunoregulatory protein classes were discovered and validated by Western blot tests. These included, but were not limited to, cystatin C, cystatin B, chitinase 3-like 1 protein, cofilin-1, l-plastin, superoxide dismutase, leukotriene A(4) hydrolase, and alpha-enolase. This study, using a unique proteomics platform, provides novel insights into virus-host cell interactions that likely affect the functional role of macrophages in HIV disease.     

The tumor gene survivin is highly expressed in adult renal tubular cells: implications for a pathophysiological role in the kidney

The inhibitor of apoptosis protein survivin is of critical importance for regulation of cellular division and survival. Published data point to a restricted function of survivin in embryonic development and cancer; thus survivin has been broadly proposed as an ideal molecular target for specific anti-cancer therapy. In contrast to this paradigm, we report here broad expression of survivin in adult differentiated tissues, as demonstrated at the mRNA and protein levels. Focusing on the kidney, survivin is strongly expressed in proximal tubuli, particularly at the apical membrane, which can be verified in rat, mouse, and human kidneys. In the latter, survivin expression seems to be even stronger in proximal tubuli than in adjacent cancerous tissue. Primary and immortalized human renal tubular cells also showed high levels of survivin protein expression, and RNA interference resulted in a partial G(2)/M arrest of the cell cycle and increased rate of apoptosis. In conclusion, survivin may be of importance for renal pathophysiology and pathology. The predominant apical expression of survivin may indicate a further, yet unknown, function. Interventional strategies to inhibit survivin's function in malignancy need to be carefully (re)evaluated for renal side effects, as well as for other possible organ dysfunctions.     

Demonstration of pharmaceutical tablet coating process by injection molding technology

We demonstrate the coating of tablets using an injection molding (IM) process that has advantage of being solvent free and can provide precision coat features. The selected core tablets comprising 10% w/w griseofulvin were prepared by an integrated hot melt extrusion-injection molding (HME-IM) process. Coating trials were conducted on a vertical injection mold machine. Polyethylene glycol and polyethylene oxide based hot melt extruded coat compositions were used. Tablet coating process feasibility was successfully demonstrated using different coating mold designs (with both overlapping and non-overlapping coatings at the weld) and coat thicknesses of 150 and 300?μm. The resultant coated tablets had acceptable appearance, seal at the weld, and immediate drug release profile (with an acceptable lag time). Since IM is a continuous process, this study opens opportunities to develop HME-IM continuous processes for transforming powder to coated tablets.     

Impact of undernutrition on the pharmacokinetics of chemotherapy in children with cancer: A systematic review

Objectives

This systematic review provides an overview of the effect of undernutrition on the pharmacokinetics of chemotherapy in children with cancer.

Methods

PubMed, Embase, and Cochrane were searched to identify eligible studies. This study uses the definition for undernutrition from the World Health Organization and the Gomez classification.

Results

Four studies with a total of 668 children with cancer were included and n = 121 (18%) were undernourished. Significant decreased clearance rates were found for vincristine in undernourished children compared to children with a normal nutritional status.

Conclusion

Presenting outcomes only show significant changes in the pharmacokinetics of vincristine in undernourished children with cancer. However, data are scarce, groups were small, and none of the studies included severely undernourished children. In order to improve outcomes for (severely) undernourished children with cancer, more pharmacokinetic research is needed. The ultimate goal would be to develop subgroups, and ultimately individualized drug dosing in order to improve outcomes for children with cancer worldwide.     

Impact of a functionalized olive oil extract on the uterus and the bone in a model of postmenopausal osteoporosis

Purpose

The Mediterranean diet rich in fruits, vegetables and olive oil has been related to a lower osteoporosis incidence and accordingly to a reduced fracture risk. These observations might be mediated by the active constituents of extra virgin olive oil, and especially polyphenols. In the context of exploring the features of olive oil active constituents on postmenopausal osteoporosis, an extra virgin olive oil total polyphenolic fraction (TPF) was isolated and its effect on the bone loss attenuation was investigated.

Methods

Female Lewis rats were ovariectomized and fed a diet enriched with a total phenolic extract of extra virgin olive oil in a concentration of 800 mg/kg diet.

Results

Oleocanthal, one compound of the polyphenolic fraction, showed a higher relative estrogen receptor binding affinity to the ERα compared to the ERβ. While the TPF only slightly induced the uterine wet weight (490.7 ± 53.7 vs. 432.7 ± 23, p = 0.058), TPF regulated estrogen response genes in the uterus (progesterone receptor, antigen identified by monoclonal antibody Ki67, complement C3). Comparing the quantified bone parameters, the oral TPF substitution did not attenuate the ovariectomy-induced bone loss.

Conclusions

The administration of extra virgin olive oil polyphenols regulated uterine estrogen response marker genes in an E2-agonistic manner. The bone loss induced by estrogen ablation was not mitigated by treatment with the polyphenolic extract.     

Health-related quality of life after TAPP repair for the sportsmen’s groin

Background

Sportsmen’s groin (SG) is a clinical diagnosis of chronic, painful musculotendinous injury to the medial inguinal floor in the absence of a groin hernia. Long-term results for laparoscopic inguinal hernia repair, especially data on health-related quality of life (HRQOL), are scant and there are no available data whatsoever on HRQOL after SG. The main goal of this study was to compare postoperative QOL data in the long term after transabdominal preperitoneal hernioplasty (TAPP) in groin hernia and SG patients with QOL data of a normal population.

Methods

This study included all patients (n = 559) who underwent TAPP repair between 2000 and 2005. Forty seven patients (8.4 %) were operated on for SG. We sent out the Short Form 36 Health Survey (SF-36) questionnaire for QOL evaluation. QOL data were compared with data from an age- and sex-matched normal population.

Results

Ultimately, 383 completed questionnaires were available for evaluation (69 % response rate). The mean follow-up time was 94 ± 20 months. In the SG group there were statistically significant differences in three subscales of the SF-36 and the mental component summary measure, showing better results for the SG group compared to the sex- and age-matched normal group data. There were no statistically significant differences between groin hernia patients and the sex- and age-matched normal population.

Conclusion

TAPP repair for SG as well as groin hernia results in good HRQOL in the long term. Results for SG patients are comparable with QOL data of a normal population or even better.
