Detection of significant liver fibrosis in Chinese psoriasis patients receiving methotrexate: a comparison between transient elastography and liver histology.

INTRODUCTION: Methotrexate (MTX) is effective for treating psoriasis and psoriatic arthritis, but its potential hepatoxicity remains a concern. Liver biopsy, the gold standard for detecting MTX-induced liver injury, is invasive and carries considerable risk. Transient elastography (TE) offers a non-invasive alternative for detecting advanced liver fibrosis. This study investigated the performance of TE in detecting MTX-induced liver fibrosis among Chinese psoriasis patients, compared with liver biopsy. METHODS: This study included adult patients with clinical psoriasis. Liver stiffness measurement using TE was performed in patients receiving MTX. Exclusion criteria were known liver cirrhosis, positive viral hepatitis carrier status, or conditions influencing TE performance. Liver biopsy was performed when liver stiffness was ≥7.1 kilopascals (kPa) or when the total cumulative dose (TCD) of MTX was ≥3.5 g. RESULTS: A total of 228 patients were screened; among 34 patients who met the inclusion criteria, nine (26.5%) had significant liver fibrosis (Roenigk grade ≥3a). The area under the receiver operating characteristic curve was 0.76 (95% confidence interval=0.59-0.93; P=0.021), indicating that TE had satisfactory performance in detecting liver fibrosis. A cut-off value of 7.1 kPa of liver stiffness yielded 100% sensitivity and 68% specificity. Liver fibrosis was not correlated with the TCD of MTX or the duration of MTX use; it was significantly correlated with obesity and diabetes status (body mass index ≥30 kg/m2, waist circumference ≥138 cm, and glycated haemoglobin level ≥7.8%). CONCLUSION: Transient elastography is reliable and superior to the TCD for detecting liver fibrosis in Chinese psoriasis patients receiving MTX. Liver biopsy should be reserved for high-risk patients or patients with liver stiffness ≥11.7 kPa on TE.

Modelling a Consultant Workforce for the United Kingdom: needs-based planning for Dental Public Health.

OBJECTIVE: To develop a needs-based workforce planning model to explore specialist workforce capacity and capability for the effective, efficient, and safe provision of services in the United Kingdom (UK); and test the model using Dental Public Health (DPH). BASIC RESEARCH DESIGN: Data from a national workforce survey, national audit, and specialty workshops in 2020 and 2021 set the parameters for a safe effective DPH workforce. A working group drawing on external expertise, developed a conceptual workforce model which informed the mathematical modelling, taking a Markovian approach. The latter enabled the consideration of possible scenarios relating to workforce development. It involved exploration of capacity within each career stage in DPH across a time horizon of 15 years. Workforce capacity requirements were calculated, informed by past principles. RESULTS: Currently an estimated 100 whole time equivalent (WTE) specialists are required to provide a realistic basic capacity nationally for DPH across the UK given the range of organisations, population growth, complexity and diversity of specialty roles. In February 2022 the specialty had 53.55 WTE academic/service consultants, thus a significant gap. The modelling evidence suggests a reduction in DPH specialist capacity towards a steady state in line with the current rate of training, recruitment and retention. The scenario involving increasing training numbers and drawing on other sources of public health trained dentists whilst retaining expertise within DPH has the potential to build workforce capacity. CONCLUSIONS: Current capacity is below basic requirements and approaching 'steady state'. Retention and innovative capacity building are required to secure and safeguard the provision of specialist DPH services to meet the needs of the UK health and care systems.

Cutaneous manifestations, viral load, and prognosis among hospitalised patients with COVID-19: a cohort study.

INTRODUCTION: Various cutaneous manifestations have been reported as symptoms of coronavirus disease 2019 (COVID-19), which may facilitate early clinical diagnosis and management. This study explored the incidence of cutaneous manifestations among hospitalised patients with COVID-19 and investigated its relationships with viral load, co-morbidities, and outcomes. METHODS: This retrospective study included adult patients admitted to a tertiary hospital for COVID-19 from July to September 2020. Clinical information, co-morbidities, viral load (cycle threshold [Ct] value), and outcomes were analysed. RESULTS: In total, 219 patients with confirmed COVID-19 were included. Twenty patients presented with new onset of rash. The incidence of new rash was 9.1% (95% confidence interval=6.25%-14.4%). The most common manifestations were maculopapular exanthem (n=6, 42.9%, median Ct value: 24.8), followed by livedo reticularis (n=4, 28.6%, median Ct value: 21.3), varicella-like lesions (n=2, 14.3%, median Ct value: 19.3), urticaria (n=1, 7.1%, median Ct value: 14.4), and acral chilblain and petechiae (n=1, 7.1%, median Ct value: 33.1). The median Ct values for patients with and without rash were 22.9 and 24.1, respectively (P=0.58). There were no significant differences in mortality or hospital stay between patients with and without rash. Patients with rash were more likely to display fever on admission (P<0.01). Regardless of cutaneous manifestations, patients with older age, hypertension, and chronic kidney disease stage ≥3 had significantly higher viral load and mortality (P<0.05). CONCLUSION: This study revealed no associations between cutaneous manifestation and viral load or clinical outcomes. Older patients with multiple co-morbidities have risks of high viral load and mortality; they should be closely monitored.

Is the use of tobacco products, especially electronic nicotine delivery systems (ENDS), associated with the incidence of oral health outcomes among US adults?

DESIGN: Cohort study. SAMPLE SELECTION: Data were pooled from wave (W) 1 to W5 (2013-2019) of the Population Assessment of Tobacco and Health Study Restricted-Use Files. The W1 cohort respondents were interviewed at all five waves who were aged 18 years and older without a lifetime history of each of the six oral health outcomes (gum disease, precancerous oral lesions, bone loss around teeth, bleeding after brushing or flossing, loose teeth, number of teeth removed because of tooth decay or gum disease). DATA ANALYSIS: Data analysis was performed from October 2021 to September 2022. To assess associations between current established tobacco use and incidence of adverse oral health outcomes at the next wave, adjusted hazard ratios (AHRs) and 95% CIs were calculated using Cox proportional hazards models. RESULTS: Cigarette smoking was positively associated with incidence of gum disease diagnosis (AHR, 1.33; 95% CI, 1.11-1.60), loose teeth (AHR, 1.35; 95% CI, 1.05-1.75), and one or more teeth removed (AHR, 1.43; 95% CI, 1.18-1.74). Smoking any cigars was positively associated with incidence of precancerous oral lesions (AHR, 2.18; 95% CI, 1.38-3.43). Hookah smoking was positively associated with incidence of gum disease diagnosis (AHR, 1.78; 95% CI, 1.20-2.63). Use of electronic nicotine delivery systems (ENDS) was positively associated with incidence of bleeding after brushing or flossing (AHR, 1.27; 95% CI, 1.04-1.54). Snus and smokeless tobacco (excluding snus) were not significantly associated with incidence of gum disease diagnosis or precancerous oral lesions. CONCLUSIONS: This cohort study confirmed associations of current combustible tobacco use with incidence of adverse oral health outcomes. It also showed an association between current ENDS use and incidence of bleeding after brushing or flossing.

Effect of implant rehabilitation on oral health-related quality of life with three different implant strategies.

Design Non-randomised controlled trial.Case selection Patients requiring dental implants were recruited from a private dental surgery in Spain. According to the clinical diagnosis and patient preference, patients were assigned to one of the following three treatment protocols: the conventional treatment (CGCL), in which implants were inserted after flap elevation without guiding templates; the guided surgery/conventional loading group (GSCL); and the guided surgery/immediate loading group (GSIL).Data analysis An oral examination and a questionnaire-based interview were carried out at baseline and three months after the delivery of the definitive prosthetic rehabilitation. Two complementary indicators, Oral Impacts on Daily Performances (OIDP) and Oral Satisfaction Scale (OSS) were used to assess the changes in oral health-related quality of life (OHQoL). Paired t-tests were used to compare the within-subject change scores. ANOVA tests were used to compare quantitative variables between groups. Chi-square tests were used to compare the distribution of data between groups. Effect size was used to assess the relative responsiveness of different health indicators and to compare the amount of change resulting from different treatment protocols. A forward stepwise logistic regression analysis was performed to predict the risk of having impact after treatment.Results A total of 104 patients were recruited: CGCL (n = 40), GSCL (n = 35) and GSIL (n = 29). At baseline, the OHQoL was significantly greater among those assigned to CGCL (2.4 ± 1.3) than those assigned to GSCL (3.3 ± 1.3), which were both greater than those patients assigned to GSIL (4.6 ± 2.0). After implant therapy, the oral wellbeing was significantly better than at baseline, and patient satisfaction was greater when the implants were loaded immediately (8.7 ± 1.1) than if the prosthetic rehabilitation was delayed (8.3 ± 1.1). In the GSIL group, the effect size of the OIDP exceeded the threshold value of 0.8 for all of the OIDP domains and for the total OIDP score and patient satisfaction.Conclusions A global improvement in the OHQoL scores and patient satisfaction was observed after implant therapy, but the change was marked greater in the GSIL group.

Provision of dental hospital services during the COVID-19 epidemic.

DATA SOURCES: Information about health services provision of public tertiary dental hospitals in China mainland was retrieved through a web search engine. DATA ANALYSIS: The status of non-emergency dental services, emergency dental services and online professional consultation was recorded and analysed. If telehealth was provided, the charge, means of access, service time and service content were investigated. The geographical distribution of hospitals was recorded and classified. RESULTS: A total of 48 dental hospitals were included in the study. All 48 dental hospitals suspended general non-emergency dental treatment. They provided emergency dental services only. CONCLUSIONS: There was a significant change in the health service provision of Chinese dental hospitals during the COVID-19 epidemic and wider use of telehealth in the eastern region.

Antibiotic management of acute pharyngitis in primary care.

The Centre for Health Protection of the Department of Health has convened the Advisory Group on Antibiotic Stewardship Programme in Primary Care (the Advisory Group) to formulate guidance notes and strategies for optimising judicious use of antibiotics and enhancing the Antibiotic Stewardship Programme in Primary Care. Acute pharyngitis is one of the most common conditions among out-patients in primary care in Hong Kong. Practical recommendations on the diagnosis and antibiotic treatment of acute streptococcal pharyngitis are made by the Advisory Group based on the best available clinical evidence, local prevalence of pathogens and associated antibiotic susceptibility profiles, and common local practice.

Ground flaxseed reverses protection of a reduced-fat diet against Citrobacter rodentium-induced colitis.

Flaxseed is high in ω-3 polyunsaturated fatty acids, fiber, and lignans known to lower cholesterol levels. However, its use for prevention or treatment of inflammatory bowel diseases has yielded mixed results, perhaps related to dietary interactions. In this study, we evaluated the impact of ground flaxseed supplementation on the severity of Citrobacter rodentium-induced colitis in the setting of either a high-fat (HF, ~36%kcal) or reduced-fat (RF, ~12%kcal) diet. After weaning, C57BL/6 mice ( n = 8-15/treatment) were fed ground flaxseed (7 g/100 g diet) with either HF (HF Flx) or RF (RF Flx) diets for 4 wk before infection with C. rodentium or sham gavage. Weight changes, mucosal inflammation, pathogen burden, gut microbiota composition, tissue polyunsaturated fatty acids, and cecal short-chain fatty acids were compared over a 14-day infection period. The RF diet protected against C. rodentium-induced colitis, whereas the RF Flx diet increased pathogen burden, exacerbated gut inflammation, and promoted gut dysbiosis. When compared with the RF diet, both HF and HF Flx diets resulted in more severe pathology in response to C. rodentium infection. Our findings demonstrate that although an RF diet protected against C. rodentium-induced colitis and associated gut dysbiosis in mice, beneficial effects were diminished with ground flaxseed supplementation. NEW & NOTEWORTHY Our results demonstrate a strong protective effect of a reduced-fat diet against intestinal inflammation, dysbiosis, and pathogen burden during Citrobacter rodentium-induced colitis. However, ground flaxseed supplementation in the setting of a reduced-fat diet exacerbated colitis despite higher levels of intestinal n-3 polyunsaturated fatty acids and cecal short-chain fatty acids.

Intraosseous basivertebral nerve ablation for the treatment of chronic low back pain: a prospective randomized double-blind sham-controlled multi-center study.

PURPOSE: To evaluate the safety and efficacy of radiofrequency (RF) ablation of the basivertebral nerve (BVN) for the treatment of chronic low back pain (CLBP) in a Food and Drug Administration approved Investigational Device Exemption trial. The BVN has been shown to innervate endplate nociceptors which are thought to be a source of CLBP. METHODS: A total of 225 patients diagnosed with CLBP were randomized to either a sham (78 patients) or treatment (147 patients) intervention. The mean age within the study was 47 years (range 25-69) and the mean baseline ODI was 42. All patients had Type I or Type II Modic changes of the treated vertebral bodies. Patients were evaluated preoperatively, and at 2 weeks, 6 weeks and 3, 6 and 12 months postoperatively. The primary endpoint was the comparative change in ODI from baseline to 3 months. RESULTS: At 3 months, the average ODI in the treatment arm decreased 20.5 points, as compared to a 15.2 point decrease in the sham arm (p = 0.019, per-protocol population). A responder analysis based on ODI decrease ≥ 10 points showed that 75.6% of patients in the treatment arm as compared to 55.3% in the sham control arm exhibited a clinically meaningful improvement at 3 months. CONCLUSION: Patients treated with RF ablation of the BVN for CLBP exhibited significantly greater improvement in ODI at 3 months and a higher responder rate than sham treated controls. BVN ablation represents a potential minimally invasive treatment for the relief of chronic low back pain. These slides can be retrieved under Electronic Supplementary Material.

Telepsychiatry for stable Chinese psychiatric out-patients in custody in Hong Kong: a case-control pilot study.

INTRODUCTION: In Hong Kong, persons in custody receive primary medical care within the institutions of the Correctional Services Department (CSD). However, for psychiatric care, persons in custody must attend specialist out-patient clinics (SOPCs), which may cause embarrassment and stigmatisation. The aim of this interventional pilot study was to compare teleconsultations with face-to-face consultations for a group of stable Chinese psychiatric out-patients in custody. METHODS: A total of 86 stable Chinese male out-patients in custody were recruited for psychiatric teleconsultations. They were compared with 249 age-matched Chinese male out-patients in custody attending standard face-to-face psychiatric consultations at other SOPCs. The two groups had comparable baseline characteristics including age, education level, and 12-item Chinese General Health Questionnaire (C-GHQ-12) score. A satisfaction survey of patients towards the teleconsultation was also carried out. RESULTS: Compared with the face-to-face consultation group, the teleconsultation group showed a significantly better result in the difference in C-GHQ-12 scores before and after consultations (P=0.023). The correlation between the first and second teleconsultations also showed a moderate positive relationship (r=0.309). The satisfaction survey showed a favourable response to teleconsultations. No significant adverse events were identified for the teleconsultation group. CONCLUSIONS: The results suggest that teleconsultations are a sustainable and safe alternative to face-to-face consultations for stable Chinese psychiatric out-patients in custody.

Estrogen, progesterone, and HER2/neu receptor discordance between primary and metastatic breast tumours-a review.

Discordance in estrogen (ER), progesterone (PR), and HER2/neu status between primary breast tumours and metastatic disease is well recognized. In this review, we highlight how receptor discordance between primary tumours and paired metastasis can help elucidate the mechanism of metastasis but can also effect patient management and the design of future trials. Discordance rates and ranges were available from 47 studies (3384 matched primary and metastatic pairs) reporting ER, PR, and HER2/neu expression for both primary and metastatic sites. Median discordance rates for ER, PR, and HER2/neu were 14 % (range 0-67 %, IQR 9-25 %), 21 % (range 0-62 %, IQR 15-41 %), and 10 % (range 0-44 %, IQR 4-17 %), respectively. Loss of receptor expression was more common (9.17 %) than gain (4.51 %). Discordance rates varied amongst site of metastasis with ER discordance being highest in bone metastases suggesting that discordance is a true biological phenomenon. Discordance rates vary for both the biomarker and the metastatic site. Loss of expression is more common than gain. This can affect patient management as it can lead to a reduction in both the efficacy and availability of potential therapeutic agents. Future studies are recommended to explore both the mechanisms of discordance as well as its impact on patient outcome and management.

Whole-body vibration of mice induces articular cartilage degeneration with minimal changes in subchondral bone.

OBJECTIVE: Low-amplitude, high-frequency whole-body vibration (WBV) has been adopted for the treatment of musculoskeletal diseases including osteoarthritis (OA); however, there is limited knowledge of the direct effects of vibration on joint tissues. Our recent studies revealed striking damage to the knee joint following exposure of mice to WBV. The current study examined the effects of WBV on specific compartments of the murine tibiofemoral joint over 8 weeks, including microarchitecture of the tibia, to understand the mechanisms associated with WBV-induced joint damage. DESIGN: Ten-week-old male CD-1 mice were exposed to WBV (45 Hz, 0.3 g peak acceleration; 30 min/day, 5 days/week) for 4 weeks, 8 weeks, or 4 weeks WBV followed by 4 weeks recovery. The knee joint was evaluated histologically for tissue damage. Architecture of the subchondral bone plate, subchondral trabecular bone, primary and secondary spongiosa of the tibia was assessed using micro-CT. RESULTS: Meniscal tears and focal articular cartilage damage were induced by WBV; the extent of damage increased between 4 and 8-week exposures to WBV. WBV did not alter the subchondral bone plate, or trabecular bone of the tibial spongiosa; however, a transient increase was detected in the subchondral trabecular bone volume and density. CONCLUSIONS: The lack of WBV-induced changes in the underlying subchondral bone suggests that damage to the articular cartilage may be secondary to the meniscal injury we detected. Our findings underscore the need for further studies to assess the safety of WBV in the human population to avoid long-term joint damage.

Combining ultrasound and lactobacilli treatment for high-fat-diet-induced obesity in mice.

Chronic systemic lipopolysaccharide-induced inflammation can cause obesity. In animal experiments, lactobacilli have been shown to inhibit obesity by modifying the gut microbiota, controlling inflammation and influencing the associated gene expression. A previous study found that high-fat-diet-induced (HFD) obesity was suppressed by lactobacilli ingestion in rats via the inhibition of parasympathetic nerve activity. This study explored the combined use of lactobacilli ingestion and ultrasound (US) to control body weight and body fat deposition in HFD mice over an 8-week experimental period. Male C57BL/6J mice received an HFD during treatment and were randomly divided into four groups: (i) control group (H), (ii) lactobacilli alone (HB), (iii) US alone (HU) and (iv) lactobacilli combined with US (HUB). The US was targeted at the inguinal portion of the epididymal fat pad on the right side. At the 8th week, body weight had decreased significantly in the HUB group (15.56 ± 1.18%, mean ± SD) group compared with the HU (26.63 ± 0.96%) and H (32.62 ± 5.03%) groups (p < 0.05). High-resolution microcomputed tomography (micro-CT) scans revealed that the reduction in total body fat volume was significantly greater in the HUB group (69%) than in the other two experimental groups (HB, 52%; HU, 37%; p < 0.05). The reductions in the thickness of the subcutaneous epididymal fat pads were significantly greater in the HUB group (final thickness: 340 ± 7 µm) than in the H (final thickness: 1150 ± 21 µm), HB (final thickness: 1060 ± 18 µm) and HU (final thickness: 370 ± 5 µm) groups (all p < 0.05). Combination therapy with lactobacilli and US appears to enhance the reduction in body weight, total and local body fat deposition, adipocyte size and plasma lipid levels over an 8-week period over that achieved with lactobacilli or US alone in HFD mice. These results indicate that US treatment alone can reduce hyperlipidemia in HFD mice.

Methodology for the development of the NHF-McMaster Guideline on Care Models for Haemophilia Management.

BACKGROUND: Rigorous and transparent methods are necessary to develop clinically relevant and evidence-based practice guidelines. We describe the development of the National Hemophilia Foundation-McMaster Guideline on Care Models for Haemophilia Management, which addresses best practices in haemophilia care delivery. METHODS: We assembled a Panel of persons with haemophilia (PWH), parents of PWH, clinical experts and guideline methodologists. Conflicts of interest were disclosed and managed throughout. Panel members and key stakeholders were surveyed to develop the guideline questions and identify patient-important outcomes. Systematic reviews of the literature were conducted for all factors important in decision-making: benefits and harms; patient values and preferences; resource implications; acceptability; equity; and feasibility. We used the GRADE approach to create evidence profiles to evaluate the evidence and present key results. Evidence to Decision frameworks were created to guide the Panel in making evidence-based recommendations. When evidence was very low quality or not available, evidence from other chronic disease populations was presented to the Panel to inform the recommendations. Additionally, we systematically pooled observations from experts, and conducted qualitative interviews exploring key stakeholder experiences and perspectives. The Panel made recommendations for each guideline question and elaborated on research priorities, implementation considerations, and monitoring. Final recommendations were circulated for public and peer review. CONCLUSIONS: Despite the paucity of high-quality evidence typical of a rare condition such as haemophilia, we successfully applied a rigorous and transparent methodology based on GRADE to develop an evidence-based clinical practice guideline.

Understanding stakeholder important outcomes and perceptions of equity, acceptability and feasibility of a care model for haemophilia management in the US: a qualitative study.

INTRODUCTION: Care for persons with haemophilia (PWH) is most commonly delivered through the integrated care model used by Hemophilia Treatment Centers (HTCs). Although this model is widely accepted as the gold standard for the management of haemophilia; there is little evidence comparing different care models. AIM: We performed a qualitative study to gain insight into issues related to outcomes, acceptability, equity and feasibility of different care models operating in the US. METHODS: We used a qualitative descriptive approach with semi-structured interviews. Purposive sampling was used to recruit individuals with experience providing or receiving care for haemophilia in the US through either an integrated care centre, a specialty pharmacy or homecare company, or by a specialist in a non-specialized centre. Persons with haemophilia, parents of PWH aged ≤18, healthcare providers, insurance company representatives and policy developers were invited to participate. RESULTS AND CONCLUSIONS: Twenty-nine interviews were conducted with participants representing 18 US states. Participants in the study sample had experience receiving or providing care predominantly within an HTC setting. Integrated care at HTCs was highly acceptable to participants, who appreciated the value of specialized, expert care in a multidisciplinary team setting. Equity and feasibility issues were primarily related to health insurance and funding limitations. Additional research is required to document the impact of care on health and psychosocial outcomes and identify effective ways to facilitate equitable access to haemophilia treatment and care.

Integrated multidisciplinary care for the management of chronic conditions in adults: an overview of reviews and an example of using indirect evidence to inform clinical practice recommendations in the field of rare diseases.

BACKGROUND: Integrated care models have been adopted for individuals with chronic conditions and for persons with rare diseases, such as haemophilia. OBJECTIVE: To summarize the evidence from reviews for the effects of integrated multidisciplinary care for chronic conditions in adults and to provide an example of using this evidence to make recommendations for haemophilia care. SEARCH METHODS: We searched MEDLINE, EMBASE, CINAHL and Cochrane Database of Systematic Reviews up to January 2016, and reviewed reference lists of retrieved papers. SELECTION CRITERIA: Systematic reviews of at least one randomized study, on adults with non-communicable chronic conditions. DATA COLLECTION AND ANALYSIS: Two investigators independently assessed eligibility and extracted data. Quality of reviews was assessed using ROBIS, and the evidence assessed using GRADE. RESULTS: We included seven reviews reporting on three chronic conditions. We found low to high quality evidence. Integrated care results in a reduction in mortality; likely a reduction in emergency visits and an improvement in function; little to no difference in quality of life, but shorter hospital stays; and may result in little to no difference in missed days of school or work. No studies reported educational attainment, or patient adherence and knowledge. When used for haemophilia, judgment about the indirectness of the evidence was driven by disease, intervention or outcome characteristics. CONCLUSION: This overview provides the most up to date evidence on integrated multidisciplinary care for chronic conditions in adults, and an example of how it can be used for guidelines in rare diseases.

Care models in the management of haemophilia: a systematic review.

BACKGROUND: Haemophilia care is commonly provided via multidisciplinary specialized management. To date, there has been no systematic assessment of the impact of haemophilia care delivery models on patient-important outcomes. OBJECTIVE: To conduct a systematic review of published studies assessing the effects of the integrated care model for persons with haemophilia (PWH). SEARCH METHODS: We searched MEDLINE, EMBASE and CINAHL up to April 22, 2015, contacted experts in the field, and reviewed reference lists. SELECTION CRITERIA: Randomized and non-randomized studies of PWH or carriers, focusing mainly on the assessment of care models on delivery. DATA COLLECTION AND ANALYSIS: Two investigators independently screened title, abstract, and full text of retrieved articles for inclusion. Risk of bias and overall quality of evidence was assessed using Cochrane's ACROBAT-NRSI tool and GRADE respectively. Relative risks, mean differences, proportions, and means and their variability were calculated as appropriate. RESULTS: 27 non-randomized studies were included: eight comparative and 19 non-comparative studies. We found low- to very low-quality evidence that in comparison to other models of care, integrated care may reduce mortality, hospitalizations and emergency room visits, may lead to fewer missed days of school and work, and may increase knowledge seeking. CONCLUSION: Our comprehensive review found low- to very low-quality evidence from a limited number of non-randomized studies assessing the impact of haemophilia care models on some patient-important outcomes. While the available evidence suggests that adoption of the integrated care model may provide benefit to PWH, further high-quality research in the field is needed.

NHF-McMaster Guideline on Care Models for Haemophilia Management.

This guideline was developed to identify evidence-based best practices in haemophilia care delivery, and discuss the range of care providers and services that are most important to optimize outcomes for persons with haemophilia (PWH) across the United States. The guideline was developed following specific methods described in detail in this supplement and based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation approach). Direct evidence from published literature and the haemophilia community, as well as indirect evidence from other chronic diseases, were reviewed, synthesized and applied to create evidence-based recommendations. The Guideline panel suggests that the integrated care model be used over non-integrated care models for PWH (conditional recommendation, moderate certainty in the evidence). For PWH with inhibitors and those at high risk for inhibitor development, the same recommendation was graded as strong, with moderate certainty in the evidence. The panel suggests that a haematologist, a specialized haemophilia nurse, a physical therapist, a social worker and round-the-clock access to a specialized coagulation laboratory be part of the integrated care team, over an integrated care team that does not include all of these components (conditional recommendation, very low certainty in the evidence). Based on available evidence, the integrated model of care in its current structure, is suggested for optimal care of PWH. There is a need for further appropriately designed studies that address unanswered questions about specific outcomes and the optimal structure of the integrated care delivery model in haemophilia.

Intrarenal abscess caused by community-associated methicillin-resistant Staphylococcus aureus in a transplanted kidney.

Emergence of multidrug-resistant bacteria is important in solid organ transplant recipients, because it can jeopardize patient and graft survival. Methicillin-resistant Staphylococcus aureus (MRSA) infections are not rare in kidney transplant recipients. On the other hand, infections related to community-associated MRSA (CA-MRSA) strains are seldom reported in the literature. Herein, we report the first patient, to our knowledge, with CA-MRSA renal graft abscess who was successfully treated with drainage and parenteral antibiotics.
