Increasing capacity for the treatment of common musculoskeletal problems: A non-inferiority RCT and economic analysis of corticosteroid injection for shoulder pain comparing a physiotherapist and orthopaedic surgeon

Background Role substitution is a strategy employed to assist health services manage the growing demand for musculoskeletal care. Corticosteroid injection is a common treatment in this population but the efficacy of its prescription and delivery by physiotherapists has not been established against orthopaedic standards. This paper investigates whether corticosteroid injection given by a physiotherapist for shoulder pain is as clinically and cost effective as that from an orthopaedic surgeon. Methods A double blind non-inferiority randomized controlled trial was conducted in an Australian public hospital orthopaedic outpatient service, from January 2013 to June 2014. Adults with a General Practitioner referral to Orthopaedics for shoulder pain received subacromial corticosteroid and local anaesthetic injection prescribed and delivered independently by a physiotherapist or a consultant orthopaedic surgeon. The main outcome measure was total Shoulder Pain and Disability Index (SPADI) score at baseline, six and 12 weeks, applying a non-inferiority margin of 15 points. Secondary outcomes tested for superiority included pain, shoulder movement, perceived improvement, adverse events, satisfaction, quality of life and costs. Results 278 participants were independently assessed by the physiotherapist and the orthopaedic surgeon, with 64 randomised (physiotherapist 33, orthopaedic surgeon 31). There were no significant differences in baseline characteristics between groups. Non-inferiority of injection by the physiotherapist was declared from total SPADI scores at 6 and 12 weeks (upper limit of the 95% one-sided confidence interval 13.34 and 7.17 at 6 and 12 weeks, respectively). There were no statistically significant differences between groups on any outcome measures at 6 or 12 weeks. From the perspective of the health funder, the physiotherapist was less expensive. Conclusions Corticosteroid injection for shoulder pain, provided by a suitably qualified physiotherapist is at least as clinically effective, and less expensive, compared with similar care delivered by an orthopaedic surgeon. Policy makers and service providers should consider implementing this model of care

Patient and physician perspective on sperm banking to overcome post-treatment lnfertility in young cancer patients in Pakistan

Background: Cancer survivor rates have increased over the past few decades leading to a growing interest in research related to quality of life (QoL). We attempted to explore the unique barriers that might prevent adult male cancer patients from accessing sperm cryopreservation in Pakistan. Methods: Semi-structured interviews of male cancer patients aged 18–45 years were audio-recorded in Urdu and translated to English and were transcribed ad verbatim. The topics included information regarding risk of infertility following chemotherapy, future reproductive choices, and barriers to sperm cryopreservation. Questionnaire to physicians containing four content domains of knowledge, attitude, practice, and barriers to sperm banking was also delivered. Data were entered and analyzed on SPSS. Results: Of the 25 patients interviewed, there were 10 cases of leukemia, 3 cases of lymphoma, 2 cases each of colorectal carcinoma and multiple myeloma, 1 case each of neuroblastoma and osteosarcoma, and solitary cases involving the lung, breast, thymus, brain, jaw, and testis. Four patients knew about the risk of infertility. All patients were aware of the option of sperm cryopreservation. Two patients had their sperm preserved before the initiation of chemotherapy. Perceived treatment-related expenses appeared to be the major barrier to sperm cryopreservation in nine patients. This was followed by lack of information, which was cited by eight patients, and religious reasons (n = 2 patients). Other barriers were female gender of the doctor and patient\u27s preferences. Four patients stated no barriers. Nine physicians responded to the questionnaire. Seventy-eight percent of physicians agreed that cancer treatment increases the risk of infertility. 33.3% strongly agreed and 55.6% agreed that infertility can have an adverse impact on QoL. Conclusions: There is a significant lack of awareness among male cancer patients regarding infertility following cancer treatment. It is imperative that physicians inform them of this and discuss treatment options, along with addressing potential barrier

High resolution MIC genotyping: design and application to the investigation of inflammatory bowel disease susceptibility.

The highly polymorphic nonclassical MHC class I chain-related (MIC) genes MICA and MICB encode stress inducible glycoproteins expressed on a variety of epithelial cells including intestinal cells. Interaction with the receptor NKG2D is likely to provide an important costimulatory signal for activation and proliferation of NK cells, activated macrophages and CD8 alphabeta and gammadelta T cells. Fifty-four MICA and 17 MICB alleles have been described to date. Although the functional significance of this polymorphism is not known, the high degree of nonconservative substitution, concentration to the putative ligand-binding site and recent observation that different MICA alleles bind to NKG2D with varying affinity has generated much interest. The MIC genes are attractive functional and positional candidate genes for inflammatory bowel disease susceptibility as a consequence of their position in the HLA region and expression on the gastrointestinal epithelium. We developed a robust, high-resolution PCR-SSP genotyping method that can be incorporated into the standard 'Phototyping' system and which effectively identifies 46 of 54 MICA alleles, and all 17 MICB alleles. We applied this system in combination with microsatellite genotyping of the exon 5 variable number of tandem repeats (VNTR) to the investigation of genetic susceptibility to the inflammatory bowel diseases, ulcerative colitis and Crohn's disease. We studied 248 patients with Crohn's disease, 329 with ulcerative colitis and 354 ethnically matched controls. Linkage disequilibrium patterns between HLA-B, MICA and MICB are presented. Analysis by individual allele or by multilocus haplotype failed to identify any significant disease associations

Haplotype-specific linkage disequilibrium patterns define the genetic topography of the human MHC.

Detailed knowledge of linkage disequilibrium (LD) is regarded as a prerequisite for population-based disease gene mapping. Variable patterns across the human genome are now recognized, both between regions and populations. Here, we demonstrate that LD may also vary within a genomic region in a haplotype-specific manner. In 864 Caucasian unrelated individuals, we describe haplotype-specific LD patterns across the human MHC by the construction of gene-specific allelic haplotypes at 25 loci between HLA-A and Tapasin. Strong and extensive LD is found across both common and rare haplotypes, suggesting that haplotype structure is influenced by factors other than genetic drift, including both selection and differential haplotype recombination. Knowledge of haplotype-specific LD in the HLA may explain the apparent discrepant data from previous studies of global LD, help delineate key areas in mapping HLA-associated diseases and, together with recombination data, provide valuable information about a population's demographic history and the selective pressures operating on it
