Upper extremity entrapment neuropathies are common conditions in which peripheral nerves are prone to injury at specific anatomical locations, particularly superficial regions or within fibro-osseous tunnels, resulting in pain and potential disability. Although neuropathy is primarily diagnosed clinically by physical examination and electrophysiology, imaging evaluation with ultrasound and magnetic resonance neurography are valuable complementary non-invasive and accurate tools for evaluation and can help define the site and cause of nerve dysfunction which ultimately leads to precise and timely treatment. Ultrasound, which has higher spatial resolution, can quickly and comfortably characterize the peripheral nerves in real time and can evaluate for denervation related muscle atrophy. Magnetic resonance imaging on the other hand provides excellent contrast resolution between the nerves and adjacent tissues, also between pathologic and normal segments of peripheral nerves. It can also assess the degree of muscle denervation and atrophy. As a prerequisite for nerve imaging, radiologists and sonographers should have a thorough knowledge of anatomy of the peripheral nerves and their superficial and deep branches, including variant anatomy, and the motor and sensory territories innervated by each nerve. The purpose of this illustrative article is to review the common neuropathy and nerve entrapment syndromes in the upper extremities focusing on ultrasound and magnetic resonance neurography imaging.

Lower extremity peripheral neuropathy is a commonly encountered neurologic disorder, which can lead to chronic pain, functional disability, and decreased quality of life for a patient. As diagnostic imaging modalities have improved, imaging has started to play an integral role in the detection and characterization of peripheral nerve abnormalities by non-invasively and accurately identifying abnormal nerves as well as potential causes of neuropathy, which ultimately leads to precise and timely treatment. Ultrasound, which has high spatial resolution and can quickly and comfortably characterize peripheral nerves in real time along with associated denervation muscle atrophy, and magnetic resonance neurography, which provides excellent contrast resolution between nerves and other tissues and between pathologic and normal segments of peripheral nerves, in addition to assessing reversible and irreversible muscle denervation changes, are the two mainstay imaging modalities used in peripheral nerve assessment. These two modalities are complimentary, and one may be more useful than the other depending on the nerve and location of pathology. Imaging must be interpreted in the context of available clinical information and other diagnostic studies, such as electrodiagnostic tests. Here, we offer a comprehensive overview of the role of high-resolution ultrasound and magnetic resonance neurography in the evaluation of the peripheral nerves of the lower extremity and their associated neuropathies.

Hip osteoarthritis (OA) is common and has detrimental consequences on mobility and quality of life. There is some concern of chondrotoxic effects of the steroid, as well as the anesthetic, with the risk of OA progression, also known as rapidly progressive or destructive osteoarthritis and was recently termed as rapidly progressive idiopathic arthritis (RPIA). The following article summarizes the pathophysiology of RPIA with the recent literature review on its prevalence. We will also provide our results regarding its prevalence and risk factors in our population, which is representative of an urban and suburban American population.

“The article provides a review on the imaging evaluation of common upper extremity entrapment neuropathy. The nerves are vulnerable for compression at specific anatomic locations, especially superficial locations or during pass through bony or fibromuscular tunnels. Imaging primary relies on nerve ultrasound imaging and MRI neurography to evaluate for the presence of neuropathy, nerve interruption, or a space-occupying lesion along the nerve course. The use of dedicated neurography MRI sequence can provide better evaluation of the small nerves of the upper extremity by using high-resolution sequence and vascular signal suppression techniques.”

COVID-19 has several manifestations in the musculoskeletal system, including the bones, joints, muscles, peripheral nerves, and blood vessels, many of which have imaging findings and patterns of involvement that can be detected with various imaging modalities, thus helping clinicians direct therapeutic management.

Evidence-based asthma management services have been tested in Australian community pharmacies for over 2 decades and have been well received by patients but are not retained in practice. The positive clinical outcomes of these tested services suggest the potential for wider implementation, for which the providers’ perspective is critical.

The island of Mayotte is part of the French territory and one of the European Union's Outermost Regions but there is a significant lack of data and research on health and cancers in Mayotte. This article reviews the literature on health, disease and cancer in Mayotte, from the perspectives of social science and epidemiology. It starts by shedding light on the specificities of Mahoran demography and society, and shows the healthcare infrastructure is insufficient to meet the population's needs. It then reviews social science studies on health and illness in Mayotte and shows that the political issue of migration permeates the management and the experiences of health on the island. It ends with a focus on the epidemiology of cervical cancer and a review of the available data on screening, treatment and prevention. The article concludes with a quick review of ongoing research and urgently calls for more data and research on this critical public health issue.

A delay in childbearing to later in life has increased the number of women of advanced maternal age (AMA) opting for assisted reproduction. Women should be made aware that there are age-related changes to fertility, including a decline in oocyte reserve and quality, in addition to an increase in the number of oocyte chromosomal aberrations. Success rates of assisted reproductive technology (ART) cycles decrease with advanced maternal age. There are different fertility options for women of AMA, including fertility preservation (oocyte or embryo freezing), in vitro fertilisation (IVF treatment) with or without preimplantation genetic screening and oocyte or embryo donation. Detailed counselling needs to be offered to these women with regard to the risks, success rates, ethical and legal implications of these fertility treatment options. Women of AMA should be screened for underlying medical conditions that could have an impact on maternal and neonatal morbidity and mortality.

Pregnancies at an advanced reproductive age are increasingly common. However, the safety of pregnancy remains a concern as maternal age is a recognized independent factor for various obstetric complications. Also, age is a risk factor for most systematic health problems and older women are more likely to enter into pregnancy with pre-existing conditions. At the moment there is no separate, structured guidance on preconception tests at advanced maternal age. However, the preconceptual period offers an ideal window to recognize and address underlying health issues, social issues and harmful lifestyle behaviours in order to optimize maternal health ultimately reducing infertility, perinatal morbidity and mortality. Preconception tests should be clinically relevant aiming to identify risk factors and address them to predict and prevent infertility and pregnancy complications. The importance of preconception care is magnified for women of advanced age for whom the risks are higher and the potential benefits greater.

Introduction: Telepsychiatry can improve access to psychiatric services for those who otherwise cannot easily access care. Family physicians are gatekeepers to specialized care in Ontario, so it is essential to understand predictors relating to referrals to telepsychiatry to better plan services and increase telepsychiatry adoption.Methods: This study used an annual retrospective cross-sectional study design to compare physicians who referred their patients to telepsychiatry each year from fiscal year (FY) 2008 to FY 2016. A 1-year (FY 2016) comparison of family physicians who referred to telepsychiatry (FPTs) compared to family physicians who did not refer to telepsychiatry (FPNTs) matched (1:2) by region was also conducted. Finally, we used statistical modeling to understand the predictors of referring to telepsychiatry among physicians.Results: Between FY 2008 and FY 2016, the number of patients receiving telepsychiatry increased from 925 visits to 13,825 visits. Thirty-two percent of Ontario primary care physicians referred to telepsychiatry in 2016. Several characteristics were notably different between FPTs and FPNTs: FPTs were more likely to be from a residence with less than 10,000 people, to have more nurse practitioners in the practice, and to be from a family health team than FPNTs. Rostered patients of FPTs were more likely to reside in rural areas, have more clinical complexity, and to utilize more mental health services compared to FPNTs.Conclusions: There has been an increase in the use of telepsychiatry by patients and family physicians over the study period, although there remains opportunity for significant growth. Family physicians who live in rural areas, are part of an FHT, have more NPs, with more rural and complex patients were more likely to refer to telepsychiatry. As recent pro-telemedicine policies support the growth of telepsychiatry, this study will serve as an important baseline.

There is accumulating evidence demonstrating that positive lifestyle modification and the optimization of the preconceptual period can influence the reproductive potential for both men and women. However, a large percentage of couples attending fertility clinics with potential to improve preconception habits may not always receive appropriate preconceptual advice. In addition, supplements and adjuncts that promise to increase fertility treatment success rates are marketed to infertile patients despite lack of convincing evidence supporting their benefit. This review aims to identify possible associations between lifestyle factors for couples seeking fertility treatment and fertility treatment outcomes and to offer possible explanations of the biological basis of these associations. An electronic search was conducted from 1978 through July 2019 linking preconceptual behaviors for women and men with the outcome of fertility treatment. The literature search explored the importance of numerous factors, including smoking, caffeine, alcohol, obesity, physical exercise, recreational drugs, stress, diet, supplements, alternative medicine, environmental factors, and pollutants. Some associations were found to be more significant than others. The preconceptual period is undeniably a delicate and important window which should not be overlooked during fertility counseling. Simple lifestyle modifications could positively influence fertility treatment outcomes. Fertility teams, consisting of clinicians, fertility nurses, dieticians, psychologists, exercise advisors and others, should dedicate time to offer evidence-based preconceptual advice and targeted interventions to couples seeking fertility treatment.

Embryonic aneuploidy is often found in women undergoing assisted reproduction and is a common cause of poor outcomes, particularly in women of advanced maternal age and those with recurrent miscarriage and repetitive implantation failure.The aim of pre‐implantation genetic testing for aneuploidy (PGT‐A) is to select the most competent embryo for transfer, thus improving reproductive outcome.Initial PGT‐A techniques failed to show an improvement in delivery rates and, in some trials, demonstrated inferior outcomes; however, advances in technology, combined with robust culture media and vitrification techniques, have significantly improved outcomes.Recent debate has argued for the increased clinical application of PGT‐A, particularly in women of advanced maternal age; we provide an overview of PGT‐A, including its past and associated limitations, the evolution in technology and latest outcomes, and address potential future implications.

To investigate whether paternal age exerts an independent effect on the clinical outcomes of assisted reproductive technology (ART) cycles.

Over 60% of rheumatoid arthritis (RA) patients achieve a good response after 12 months of treatment when following the European league against rheumatism (EULAR) guidelines for treatment. However, almost half of patients still suffer from moderate to severe disease activity despite this. In addition, mental health problems may remain despite reduced measures of inflammation systemically and within joints. Depression is two times more common in RA patients than in the general population, and intriguingly a bi-directional relationship with RA has been shown in cross-sectional studies. Chronic inflammation impairs the physiological responses to stress including effective coping behaviours, resulting in depression, which leads to a worse long-term outcome in RA. In RA patients, the pain score is not always solely related to inflammatory arthritis and immunological disease activity by Bąk et al. (Patient Prefer Adherence 13:223–231, [1]). Non-inflammatory pain secondary to anxiety, depression, sleep disturbance and the psychosocial situation needs to be considered whilst fibromyalgia, mechanical pain and neuropathic pain can also contribute to overall pain scores by Chancay et al. (Women's Midlife Health 5:3, [2]). Hence, the UK National Institute for Health and Care Excellence (NICE) guideline for the management of RA included psychological interventions for fatigue, low mood and social well-being (NICE NG100, 2018) [3], and the NICE clinical guidelines (CG91) [4] suggest managing mental health and depression in chronic medical conditions to improve treatment outcomes. This is a narrative review of the impact of mental health on RA disease activity in terms of patient-reported outcomes (PROs).

Direct magnetic resonance (MR) arthrography, introduced in 1987, offers enhanced visualization of intra-articular structures through joint distension. Widely recognized for accuracy, it has evolved alongside MRI technology, including 3T MRIs. Guidelines for its use were established in 2023. This article will review technical considerations and articulations in which direct MR arthrography is commonly performed and rely on what technique the literature suggests most between conventional MRI and direct MR arthrogram for the main indications. While 3T MRI competes, direct MR arthrography remains pivotal, especially when conventional MRI results are inconclusive.

Project Extension for Community Healthcare Outcomes (Project ECHO©) addresses urban-rural disparities in access to specialist care by building primary care provider (PCP) capacity through tele-education. Evidence supporting the use of this model for mental health care is limited. Therefore, this study evaluated a mental health and addictions-focused ECHO program. Primary outcome measures were PCP knowledge and perceived self-efficacy. Secondary objectives included: satisfaction, engagement, and sense of professional isolation. PCP knowledge and self-efficacy were hypothesized to improve with participation. Using Moore’s evaluation framework, we evaluated the ECHO program on participant engagement, satisfaction, learning, and competence. A pre-post design and weekly questionnaires measured primary and secondary outcomes, respectively. Knowledge test performance and self-efficacy ratings improved post-ECHO (knowledge change was significant, p< 0.001, d= 1.13; self-efficacy approached significance; p= 0.056, d= 0.57). Attrition rate was low (7.7%) and satisfaction ratings were high across all domains, with spokes reporting reduced feelings of isolation. This is the first study to report objective mental health outcomes related to Project ECHO. The results indicate high-participant retention is achievable, and provide preliminary evidence for increased knowledge and self-efficacy. These findings suggest this intervention may improve mental health management in primary care.

Objective: Rural areas in Ontario have fewer psychiatrists, making access to specialist mental health care challenging. Our objective was to characterise psychiatrists delivering and patients receiving telepsychiatry in Ontario and to determine the number of patients who accessed a psychiatrist via telepsychiatry following discharge from psychiatric hospitalisation.Method: We conducted a serial panel study to evaluate the characteristics of psychiatrists providing telepsychiatry from April 2007 to March 2013. In addition, we conducted a cross-sectional study for fiscal year 2012-2013 to examine telepsychiatry patient characteristics and create an in-need patient cohort of individuals with a recent psychiatric hospitalisation that assessed if they had follow-up with a psychiatrist in person or through telepsychiatry within 1 year of discharge.Results: In fiscal year 2012-2013, a total of 3801 people had 5635 telepsychiatry visits, and 7% (n= 138) of Ontario psychiatrists provided telepsychiatry. Of the 48,381 people identified as in need of psychiatric care, 60% saw a local psychiatrist, 39% saw no psychiatrist, and less than 1% saw a psychiatrist through telepsychiatry only or telepsychiatry in addition to local psychiatry within a year. Three northern regions had more than 50% of in-need patients fail to access psychiatry within 1 year.Conclusions: Currently, relatively few patients and psychiatrists use telepsychiatry. In addition, patients scarcely access telepsychiatry for posthospitalisation follow-up. This study, which serves as a preliminary baseline for telepsychiatry in Ontario, demonstrates that telepsychiatry has not evolved systematically to address need and highlights the importance of system-level planning when implementing telepsychiatry to optimise access to care.

ABSTRACTThe DEAD-box Helicase 19 (Ddx19) gene codes for an RNA helicase involved in both mRNA (mRNA) export from the nucleus into the cytoplasm and in mRNA translation. In unperturbed cells, Ddx19 localizes in the cytoplasm and at the cytoplasmic face of the nuclear pore. Here we review recent findings related to an additional Ddx19 function in the nucleus in resolving RNA:DNA hybrids (R-loops) generated during collision between transcription and replication, and upon DNA damage. Activation of a DNA damage response pathway dependent upon the ATR kinase, a major regulator of replication fork progression, stimulates translocation of the Ddx19 protein from the cytoplasm into the nucleus. Only nuclear Ddx19 is competent to resolve R-loops, and down regulation of Ddx19 expression induces DNA double strand breaks only in proliferating cells. Overall these observations put forward Ddx19 as an important novel mediator of the crosstalk between transcription and replication.

Preimplantation genetic diagnosis (PGD) was developed for couples at risk of transmitting a genetic disorder to their children.Before PGD, options available to these couples were remaining childless, prenatal diagnosis, gamete donation or adoption.Couples requesting PGD have in vitro fertilisation (IVF) to produce embryos for biopsy, even if they are fertile. To understand indications for PGD.To learn about the genetic work up required prior to undergoing IVF.To learn about IVF, embryogenesis, the biopsy process and when to transfer disease‐free/carrier embryo(s). PGD for ‘saviour sibling’: should couples be offered human leucocyte antigen (HLA) matched treatment for a child who is in remission or who may develop the late onset condition?PGD for sex selection: should we offer sex selection for ‘family balancing’?

Gene expression from both parental genomes is required for completion of embryogenesis. Differential methylation of each parental genome has been observed in mouse and human preimplantation embryos. It is possible that these differences in methylation affect the level of gene transcripts from each parental genome in early developing embryos. The aim of this study was to investigate if there is a parent-specific pattern of BRCA1 expression in human embryos and to examine if this affects embryo development when the embryo carries a BRCA1 or BRCA2 pathogenic mutation. Differential parental expression of ACTB, SNRPN, H19 and BRCA1 was semi-quantitatively analysed by minisequencing in 95 human preimplantation embryos obtained from 15 couples undergoing preimplantation genetic diagnosis. BRCA1 was shown to be differentially expressed favouring the paternal transcript in early developing embryos. Methylation-specific PCR showed a variable methylation profile of BRCA1 promoter region at different stages of embryonic development. Embryos carrying paternally inherited BRCA1 or 2 pathogenic variants were shown to develop more slowly compared with the embryos with maternally inherited BRCA1 or 2 pathogenic mutations. This study suggests that differential demethylation of the parental genomes can influence the early development of preimplantation embryos. Expression of maternal and paternal genes is required for the completion of embryogenesis.

K201, a 1,4-benzodiazepine derivative, acts on multiple cardiac ion channels and the ryanodine receptor. We tested whether administration of M-II, the main metabolite of K201, would terminate induced atrial flutter (AFL) or atrial fibrillation (AF) in the canine sterile pericarditis model.

The structural behavior of steelreinforced polymer concrete (PC) beams using unsaturated polyester resin binders based on recycled polyethylene terephthalate (PET) plastic waste is evaluated. Steel fibers are also used in some of the beams. The investigation includes loaddeflection and momentcurvature responses, modes of failure, cracking patterns, variation of neutral axis depth with loads, strength properties, ductility index, the effect of tensile reinforcement ratio on the flexural strength of PC beams, and the effects of shear spantodepth ratio, tensile reinforcement, and compressive strength on the shear strength of PC beams. The ultimate flexural strength of reinforced PC using resins based on recycled PET is compared to other reinforced concrete systems. The effects of steel fibers on the loaddeflection response and shear strength of reinforced PC beams are also evaluated. Resins using recycled PET offer the possibility of producing very good quality PC at a lower cost for structural applications. Also, the recycling of PET in PC helps in saving energy and in partially solving a solid waste problem posed by plastics.

(Abstracted from Reprod Biomed Online2017;35:264–271)Karyomapping and single-nucleotide polymorphism (SNP) is a new technique for diagnosing single-gene disorders (SGDs) and chromosomal rearrangements, in which cells biopsied from embryos are lysed, undergo whole-genome amplification, and are analyzed using a microarray capable of interrogating a large number of SNPs. The data produced by karyomapping reveal whether the combination of alleles on the parental chromosome(s) carrying the mutation has been inherited, and karyomapping has the potential to diagnose more than 1 serious monogenic disorder or monogenic disorder combined with a chromosomal rearrangement at once.
