Trauma in the elderly (>65 years) is an increasingly common presentation to the ED. A fall from standing height is the most common mechanism after which such patients present, and rib fracture is the most common non-spinal fracture. Thoracic injury in patients aged over 65 is associated with significant morbidity and mortality. There are currently no universally applied guidelines for assessment, investigation and management of such patients. In this expert practice review, we discuss the evidence base and options for clinical management in this vulnerable patient group.

Chronic non-specific low back pain (LBP) causes more disability than any other medical condition worldwide. Electrical muscle stimulation in combination with heat (EMS/H) for management of LBP has yet not been properly studied. Our hypothesis was that EMS/H provides better pain relief and improves subjective and objective data compared to standard treatment.

In order to manage skin conditions at a national referral hospital level in Kenya, specialized dermatology services, such as dermatologic surgery, dermatopathology, phototherapy, and sub-specialty care, should be offered, as is typically available in referral hospitals around the world. A Kenyan patient with prurigo nodularis, whose severe itch remitted after phototherapy treatment at the University of California, San Francisco (UCSF), inspired the development of a phototherapy service at Academic Model Providing Access to Healthcare (AMPATH), a partnership in Western Kenya between Moi Teaching and Referral Hospital, Moi University College of Health Sciences, and a consortium of North American academic medical centers.

Ketamine is a potent uncompetitive NMDA receptor antagonist that provides amnesia, analgesia, environmental dissociation and immobility, where it has its cytotoxic effect well described in the literature. However, the work on its genotoxic/mutagenic potentials are scarce and insufficient and does not allow a reasonable evaluation of its role. Thus, in the present work, we decided to evaluate the genotoxic and mutagenic effects of ketamine on human peripheral blood leukocytes (PBLs) and Salmonella typhimurium (TA98, TA97a, TA100, and TA102) through several well-established experimental protocols based on different parameters in the presence or not of exogenous metabolizing S9 fraction. Our data revealed that ketamine induces a weak cytotoxic effect on human PBLs after 24 h and is devoided of hemolytic effects. A small amount of DNA strand breaks levels were detected in the modified comet assay (employment of FPG enzyme) only at highest concentrations (500 and 700 μg/mL) of ketamine, highlighting our pro-oxidant data regarding ketamine. However, the oxidative DNA lesions were almost completely repaired which reflects in the lack of mutagenesis (micronuclei and chromosomal aberrations) on human PBLs and no increases in revertants numbers on S. typhimurium/microsome test (500 to 5000 μg/plate). In summary, ketamine is a weak oxidative DNA damaging agent and is devoid of mutagenic properties on eukaryotic and prokaryotic models.

Endometriosis associated pain (EAP) has a significant impact on the quality of life of those affected and their families. Recognizing that endometriosis is a chronic condition associated with an impairment in function and negative social impact, there is a shift towards reducing diagnostic delays and initiating timely management. This article provides a comprehensive and practical approach to the clinical diagnosis of EAP, which can subsequently facilitate prompt and directed treatment. The key components of the history, physical exam and high-quality imaging to evaluate suspected EAP and related pain conditions are presented. Currently, biomarkers have limited utility in the diagnosis of endometriosis, but research in this area continues; development of a reliable non-invasive test for endometriosis may further improve early identification of this condition.

Addiction is a chronic, relapsing brain disease. It is not the same as physical dependence (i.e., withdrawal) and tolerance, but is characterized by loss of control over the use of the substance, continued use despite consequences, compulsive use, and cravings. Addiction involves functional changes to brain pathways involved in reward, stress and learning, and these changes can last a long time after the addictive substance is no longer used. Repeated interruption of normal brain function from repetitive use of addictive substances can hijack normal reward mechanisms resulting in fundamental alterations in brain structure and function. Over time, addictive substances can bring about a false fixed prediction error that cannot be rectified during learning. And, for individuals who develop an addiction, initial impulsive drug use progresses to compulsive drug use and this progression also has neurobiological underpinnings. Drug addiction is partly heritable, although there is no single gene coding specifically for the disease of addiction. Genetic factors contribute to a vulnerability to develop both addiction and addiction comorbidities, and play an appreciable role in responses to and metabolism of addictive substances, and most likely, the experience of rewarding effects. Patients with pain who are addicted to opioids have, in addition to the pain disorder, a chronic relapsing brain disease that can be life-threatening. Addiction can be treated and controlled, but not cured. Treatment of pain in individuals with addiction is a complex clinical challenge. Holistic assessment, interprofessional approaches, use of established guidelines, and non-pharmacological complementary modalities are needed.

This study is to explore the quality of life (QoL) of the rural poor elderly in central China (Anhui province) and the influencing factors.A multi-stage random sampling method was used to extract 3352 effective samples of the rural elderly in Anhui, including 1206 poor and 2146 non-poor elderly subjects. Euro QoL 5-dimension questionnaire (EQ-5D) was used for the measurement of QoL. Descriptive statistics and χ test were used to compare and analyze the sociodemographic characteristics and QoL scores between poor and non-poor elderly. Multiple linear regression was used to assess the influencing factors of QoL.There were significant differences in gender, age, education levels, professions, chronic diseases, physical discomfort within 2 weeks, hospitalization within 1 year, economic sources, and migrant workers between the rural poor and non-poor elderly groups. The QoL of rural poor elderly scored significantly higher than the non-poor elderly, in all these five dimensions. The average EuroQol Visual Analogue Scale (EQ-VAS) of poor elderly was 65.689, lower than the non-poor elderly (71.039). After controlling the confounding factors, there was a significant statistical difference in the total utility score of EQ-5D between the poor and non-poor elderly groups.The QoL of poor elderly in central China is lower than non-poor elderly, with the worst dimension of pain/discomfort. The QoL of rural poor elderly in this area could be affected by many factors, to which more attention should be paid.

Studies assessing the comparative effectiveness of methadone versus buprenorphine/naloxone for opioid use disorder in real-world settings are rare – challenged by structural differences in delivery across settings and factors influencing treatment selection. We identified determinants of selection into buprenorphine/naloxone and quantified contributions of individual and provider-level covariates in a setting delivering both medications within the same healthcare settings.

Chronic back pain is one of the most common work-related diseases and most important of musculoskeletal disorders in nursing professionals and because of the physical and psychological effects, has a significant impact on quality of life (QOL). Acupressure is a holistic form of complementary medicine. This study aimed to investigate the effect of acupressure on QOL among female nurses with chronic back pain.
