RESUMEN

Objective: Remote knee osteoarthritis (OA) management programs are becoming more popular. This systematic review examined the efficacy of remote exercise programs for relieving pain in persons with knee OA. Design: We conducted a search of studies published between January 1st, 2013 to March 31st, 2021 in PubMed, Embase, and MEDLINE. We included randomized trials of patients with knee OA or chronic knee pain, studying interventions with an element of telehealth exercise management, and evaluating knee pain as an outcome. Interventions could include fully remote or both remote and in-person components. We excluded observational cohort studies, pilot studies, and studies with poor Physiotherapy Exercise Database (PEDro) scores. Two reviewers extracted pain data, consisting of mean differences from baseline and between groups, and compared them to minimum clinically important difference (MCID) thresholds. Results: We identified 1867 reports, of which eleven trials with a total of 1861 participants met inclusion criteria. Only one trial demonstrated a clinically meaningful change from baseline between groups. Four interventions were found to result in clinically meaningful improvements in pain from baseline. Conclusion: This review was limited by variability in outcome measures, intervention content, and comparators. One trial with an inactive control demonstrated clinically meaningful between group differences in pain. All four interventions demonstrating meaningful improvements from baseline included study-initiated communications to discuss and personalize remotely delivered exercise programs. More studies comparing fully or partially remote exercise programs with both active and inactive controls could help optimize the use of remote programs for management of knee OA pain.

RESUMEN

Background Anorexia nervosa has a high mortality complicated by risks of under-nourishment, over-nourishment and care can be compromised by behavioural issues. Methods This is a retrospective study of ten patients with eating disorders admitted to Sligo University Hospital, treated by a "pop-up"/on demand multidisciplinary eating disorder team. Results All were female, mean BMI on admission was 14.35kg/m2, on discharge was 16.59kg/m2, (p=0.001) and was significantly lower than the initial measurement and may represent water-loading or bowel retention. Admission biochemistry was normal in nine subjects. Six subjects experienced refeeding syndrome, one was hypoglycaemic (3.1mmol/L) in the setting of an aspiration pneumonia, and five exhibited treatment avoiding behaviour including food caching, micro exercising. The mean length of stay was 38 days and was positively correlated with weight gain during admission (p=0.02). 6-month follow up BMI was higher than admission in eight subjects and the other two voluntarily withdrew from follow-up. Conclusion There was a high incidence of treatment avoiding behaviour, initial weights were misleadingly high, admission biochemistry misleadingly normal, hypoglycaemia associated with infection, and incidence of refeeding syndrome is high. Notwithstanding this these patients can be managed safely and effectively in a general hospital with a coordinated, well-structured approach by a multidisciplinary team.

RESUMEN

Objective: To summarize the literature investigating management, treatment strategies, short- and longer-term outcomes of treatment for meniscal tear in middle-aged and older adults. Design: We performed a literature search using PubMed to identify relevant articles and selected 15 for a narrative summary on the available evidence. Results: The literature suggests that middle-age and older adults with meniscal tear may benefit from initial physical therapy (PT) potentially followed by arthroscopic partial meniscectomy (APM) for those who do not experience sufficient benefit after PT and in whom other sources of pain are deemed unlikely. There is moderate evidence to suggest that some factors at baseline, such as radiographic OA, meniscal tear type, and pain at baseline may influence outcomes after APM. Over time, APM appears to increase the risk of degenerative changes in cartilage, bone, and other knee structures as evidenced by radiograph and MRI-based assessments. Conclusion: Evidence from research investigating outcomes of treatment for meniscal tear in middle-aged and older adults demonstrates that PT is a reasonable initial treatment. More research is needed to investigate the best treatment for those who do not benefit substantially from initial PT. The evidence also demonstrates that APM may be associated with greater risk of radiographic osteoarthritic changes, though more research and the addition of enhanced quantitative MRI-assessments are needed to further detail any compositional changes in the knee. Focusing on these areas of further study will clarify whether these imaging findings are clinically meaningful.

RESUMEN

OBJECTIVE: To identify and summarize literature related to the association between mechanical symptoms (catching and locking of the knee), the presence of meniscal tear, and outcomes after arthroscopic surgery. DESIGN: We searched PubMed and hand-searched reference lists for relevant articles and selected 38 for analysis. RESULTS: Mechanical symptoms appear to have modest sensitivity (ranging 0.32-0.69), specificity (ranging 0.45-0.74) and positive predictive value (ranging 0.75-0.81) for meniscal tear. There is also very little evidence to suggest that those with mechanical symptoms experience better outcomes after arthroscopic surgery. CONCLUSION: Our examination of the literature does not support the hypothesis that mechanical symptoms are related to the presence of meniscal tear or portend better outcomes after arthroscopic surgery.

RESUMEN

AIMS: Pre-gestational diabetes mellitus (PGDM) is associated with adverse outcomes. We aimed to examine pregnancies affected by PGDM; report on these pregnancy outcomes and compare outcomes for patients with type 1 versus type 2 diabetes mellitus; compare our findings to published Irish and United Kingdom (UK) data and identify potential areas for improvement. METHODS: Between 2016 and 2018 information on 679 pregnancies from 415 women with type 1 Diabetes Mellitus and 244 women with type 2 diabetes was analysed. Data was collected on maternal characteristics; pregnancy preparation; glycaemic control; pregnancy related complications; foetal and maternal outcomes; unscheduled hospitalisations; congenital anomalies and perinatal deaths. RESULTS: Only 15.9% of women were adequately prepared for pregnancy. Significant deficits were identified in availability and attendance at pre-pregnancy clinic, use of folic acid, attaining appropriate glycaemic targets and appropriate retinal screening. The majority of pregnancies (n = 567, 83.5%) resulted in a live birth but the large number of infants born large for gestational age (LGA) (n = 280, 49.4%), born prematurely <37 weeks and requiring neonatal intensive care unit (NICU) admission continue to be significant issues. CONCLUSIONS: This retrospective cohort study identifies multiple targets for improvements in the provision of care to women with pre-gestational DM which are likely to translate into better pregnancy outcomes.

RESUMEN

Objective: To understand the enablers and barriers to implementing a set of adaptive processes aimed at supporting secondary schools to reflect on and subsequently address how they could adjust school practices, culture and the environment to create a whole school approach to promoting healthy lifestyles. Study design: A qualitative, comparative case study. Methods: Two in depth case studies were created of two purposefully selected schools in low socio-economic areas of South West England. Data were collected via meetings, observations, field notes, interviews and audit. Interviews were transcribed verbatim. Individual thematic analyses were conducted for each school and a comparative analysis approach was used to understand the barriers and enablers across both cases. Results: Schools were supported to use a health-promoting lens and identify feasible improvements through an adaptive and context specific process. The school environment and ethos were identified as the areas where schools could conceive the most adjustments to enhance the promotion of healthy lifestyle choices. With the lack of government policy for health promotion in schools (HPS), the Head teacher's approach to health was key to making meaningful changes. Conclusions: Health promoting school approaches need to be adaptive to local context, actively involve community partners and link to local initiatives where possible, with support from Head teachers and business managers. Starting with what teachers, pupils and parents see as the barriers to health can create a whole school ethos for broad reaching and sustainable HPS programmes.

RESUMEN

OBJECTIVE: To examine the effectiveness of interventions using the World Health Organization Health Promoting Schools (HPSs) framework approach in increasing physical activity (PA) and improving the diet of 11-18-year-olds. STUDY DESIGN: A systematic review guided by the National Health Services Centre for Reviews and Dissemination framework and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses. METHODS: Nine databases and trial registries were searched from 2013 to 2018 for cluster randomised controlled trials involving adolescents' aged 11-18 years. We also included relevant studies from a 2014 Cochrane Review of HPS approach on health behaviours. Data were extracted from included studies and assessed for quality. RESULTS: Twelve eligible studies were identified from seven countries. The studies varied in outcome measures, sample size, quality and duration of intervention and follow-up. Only four of the included studies were of high to moderate quality. We found some evidence of effectiveness for physical activity only interventions and limited evidence of effectiveness for nutrition only and combined PA and nutrition interventions. CONCLUSIONS: There were no discernible patterns across the studies to suggest effective mechanisms for the HPS approach. The family/community component was poorly developed and superficially reported in all studies. Future research should seek to understand how best to work in partnership with secondary schools, to foster and sustain a healthy eating and physical activity culture, which aligns with their core aims. More attention should be paid to the restriction of unhealthy foods in the school environment.

RESUMEN

AIMS: The purpose of this study was to identify the number of pregnancies affected by pre-gestational diabetes in the Republic of Ireland; to report on pregnancy outcomes and to identify areas for improvement in care delivery and clinical outcomes. METHODS: Healthcare professionals caring for women with pre-gestational diabetes during pregnancy were invited to participate in this retrospective study. Data pertaining to 185 pregnancies in women attending 15 antenatal centres nationally were collected and analysed. Included pregnancies had an estimated date of delivery between 1 January and 31 December 2015. RESULTS: The cohort consisted of 122 (65.9%) women with Type 1 diabetes and 56 (30.3%) women with Type 2 diabetes. The remaining 7 (3.8%) pregnancies were to women with maturity-onset diabetes of the young (MODY) (n = 6) and post-transplant diabetes (n = 1). Overall women were poorly prepared for pregnancy and lapses in specific areas of service delivery including pre-pregnancy care and retinal screening were identified. The majority of pregnancies 156 (84.3%) resulted in a live birth. A total of 103 (65.5%) women had a caesarean delivery and 58 (36.9%) infants were large for gestational age. CONCLUSIONS: This audit identifies clear areas for improvement in delivery of care for women with diabetes in the Republic of Ireland before and during pregnancy.

RESUMEN

The giant 2011 Tohoku-oki earthquake has been inferred to remobilise fine-grained, young surface sediment enriched in organic matter from the slope into the >7 km deep Japan Trench. Yet, this hypothesis and assessment of its significance for the carbon cycle has been hindered by limited data density and resolution in the hadal zone. Here we combine new high-resolution bathymetry data with sub-bottom profiler images and sediment cores taken during 2012-2016 in order to map for the first time the spatial extent of the earthquake-triggered event deposit along the hadal Japan Trench. We quantify a sediment volume of ~0.2 km3 deposited from spatially-widespread remobilisation of young surficial seafloor slope sediments triggered by the 2011 earthquake and its aftershock sequence. The mapped volume and organic carbon content in sediment cores encompassing the 2011 event reveals that this single tectonic event delivered >1 Tg of organic carbon to the hadal trench. This carbon supply is comparable to high carbon fluxes described for other Earth system processes, shedding new light on the impact of large earthquakes on long-term carbon cycling in the deep-sea.

RESUMEN

Anorexia nervosa affects 0.5% of the population (90% female) with the highest mortality of any psychiatric illness, usually suicide, or cardiovascular or neurological sequelae of either malnutrition or refeeding syndrome. The latter two conditions occur in the inpatient setting, carry a high mortality and are thoroughly avoidable with careful informed clinical management. This paper provides an overview of the service and care of these patients in a general hospital setting in Ireland. In response to a number of acute presentations a cross discipline Pop-up Eating Disorder Unit (psychiatrist, physician, dietician, nurse) was established in Sligo University Hospital in 2014 and has experience of 20 people treated according to the MARSIPAN guideline (Management of Really Sick Inpatients with Anorexia Nervosa). They are nursed in a designated ward with continuous cardiac monitoring (in addition 2 required ICU admission), with one-to-one continuous supervision, complete bed rest, careful calorie titration (usually nasogastric) with twice daily phosphate, magnesium, calcium and potassium concentrations measured and replaced. Sabotaging behaviour witnessed includes micro-exercising, requests for windows to be opened (in order to shiver/micro exercise), food concealment, faecal/urinary loading on weighing days, heavy hair accessories, vigorous page turning/toothbrushing/use of computer keypads and animated conversations. A cross disciplinary coordinated approach to this cohort, who often inventive in their resistance to treatment, allows safe management in a general hospital setting.

RESUMEN

BACKGROUND: Recruitment and retention of participants is crucial for statistical power and internal and external validity and participant engagement is essential for behaviour change. However, many school-based interventions focus on programme content rather than the building of supportive relationships with all participants and tend to employ specific standalone strategies, such as incentives, to improve retention. We believe that actively involving stakeholders in both intervention and trial design improves recruitment and retention and increases the chances of creating an effective intervention. METHODS: The Healthy Lifestyles Programme, HeLP (an obesity prevention programme for children 9-10 years old) was developed using intervention mapping and involved extensive stakeholder involvement in both the design of the trial and the intervention to ensure that: (i) delivery methods were suitably engaging, (ii) deliverers had the necessary skills and qualities to build relationships and (iii) the intervention dovetailed with the National Curriculum. HeLP was a year-long intervention consisting of 4 multi-component phases using a range of delivery methods. We recruited 1324 children from 32 schools from the South West of England to a cluster-randomised controlled trial to determine the effectiveness of HeLP in preventing obesity. The primary outcome was change in body mass index standard deviation score (BMI SDS) at 24 months post randomisation. Secondary outcomes included additional anthropometric and behavioural (physical activity and diet) measures at 18 and 24 months. RESULTS: Anthropometric and behavioural measures were taken in 99%, 96% and 94% of children at baseline, 18 and 24 months, respectively, with no differential follow up between the control and intervention groups at each time point. All children participated in the programme and 92% of children and 77% of parents across the socio-economic spectrum were considered to have actively engaged with HeLP. CONCLUSIONS: We attribute our excellent retention and engagement results to the high level of stakeholder involvement in both trial and intervention design, the building of relationships using appropriate personnel and creative delivery methods that are accessible to children and their families across the social spectrum.

RESUMEN

BACKGROUND: In spite of widespread use of nasal CPAP there are comparatively few studies to guide the choice of nasal prongs. OBJECTIVES: To determine whether the Fisher & Paykel Healthcare (FPH) neonatal continuous positive airway pressure (CPAP) interface was effective in providing bubble CPAP when compared to the Hudson prong interface. METHODS: The study was a randomized cross-over study of twenty newborn infants 500 g or more requiring CPAP for respiratory support at birth. Infants were randomized to either the Fisher & Paykel Healthcare or Hudson CPAP interface for twenty four hours. Crossover between interfaces occurred after subsequent twenty four hour periods. The primary outcome was the provision of desired CPAP pressures, defined as provision of CPAP within ± one cm H2O of set pressure. RESULTS: The percentage time CPAP was within ± one cm H2O of set pressure was 66.5% for the Hudson and 71.8% for the FPH interface (p = 0.66). Oxygen saturations for the Hudson interface were in target range for a median of 97.8% of the time, and, with the FPH interface, for a median of 98.2% of the time (p = 0.76). Clinically significant differences in primary or secondary outcomes between the two groups were not detected. CONCLUSIONS: The nasal CPAP interfaces studied were equally effective in achieving desired bubble CPAP pressures and target saturations.

RESUMEN

In this paper, a programme to train mental health promotion workers in programme evaluation is described and evaluated. The programme is based on adult learning values, guidelines for programme evaluation training and the general principles of mental health promotion. Facilitated over 2 days, the programme also provided individual mentoring. Training was evaluated via a questionnaire immediately before and post training, and 6 months post training (n = 28, n = 18, n = 18). Additionally, individual interviews were used with seven participants and qualitatively analysed. Results indicate significant and sustained positive changes in knowledge, confidence and behaviour and while satisfaction reduced significantly at the six month follow-up, participants' level of satisfaction towards mentoring was consistent. Post training, participants reported a greater appreciation of the importance of evaluation planning and working collaboratively.

RESUMEN

Encephalitic syndromes are a common medical emergency. The importance of early diagnosis and appropriate treatment is paramount. If initial investigations for infectious agents prove negative, other diagnoses must be considered promptly. Autoimmune encephalitides are being increasingly recognized as important (and potentially reversible) non-infectious causes of an encephalitic syndrome. We describe four patients with autoimmune encephalitis--3 auto-antibody positive, 1 auto-antibody negative--treated during the last 18 months. A comprehensive review of the literature in this expanding area will be of interest to the infectious diseases, general medical and neurology community.

RESUMEN

Malaria is a devastating disease. For transmission to occur, Plasmodium, the causative agent of malaria, must complete a complex developmental cycle in its mosquito vector. Thus, the mosquito is a potential target for disease control. Plasmodium ookinetes, which develop within the mosquito midgut, must first cross the midgut's peritrophic matrix (PM), a thick extracellular sheath that completely surrounds the blood meal. The PM poses a partial, natural barrier against parasite invasion of the midgut and it is speculated that modifications to the PM may lead to a complete barrier to infection. However, such strategies require thorough characterization of the structure of the PM. Here, we describe for the first time, the complete PM proteome of the main malaria vector, Anopheles gambiae. Altogether, 209 proteins were identified by mass spectrometry. Among them were nine new chitin-binding peritrophic matrix proteins, expanding the list from three to twelve peritrophins. Lastly, we provide a model for the putative interactions among the proteins identified in this study.

RESUMEN

Sand flies were collected at a focus of leishmaniasis in Medina County, TX, from April through October 1997 and at a focus in Bexar County, TX, from April 1998 through December 1999. Lutzomyia diabolica (Hall) were collected from April through November with peak abundance in July. The male:female ratio of Lu. diabolica was 1:6.2. Almost all female Lu. diabolica in the collections were unfed. One gravid Lu. diabolica contained 49 ova. Female Lu. anthophora (Addis) were active from February through December with three peaks in abundance suggestive of successive generations. Unfed and gravid Lu. anthophora were collected in about equal numbers. Gravid females contained from 1 to 64 ova per female. The male:female ratio was 1:1.8, with male Lu. anthophora collected in all months. One female Lu. anthophora was found infected with Leishmania in July 1999. Lutzomyia texana (Dampf) were collected from April through October with peak abundance in April during 1997. The male:female ratio was 1:1.4, with most females unfed. Two gravid Lu. texana contained 32 and 102 ova. An undescribed species of Lutzomyia was found only at the Medina County site from May through September 1997. Trapping sites four times per month versus two times per month in 1999 did not appear to adversely affect the abundance of Lu. diabolica or Lu. anthophora. There were marked differences in the species composition and relative abundance at the different sites, indicating that the spatial distribution of sand flies is patchy in nature.
