Dual single‑nucleotide polymorphism biomarker combination for opioid selection to treat cancer pain.

We have been exploring biomarkers that could help physicians select the appropriate opioid for individualized treatment of cancer pain. Recently, we identified a single nucleotide polymorphism (SNP) of (rs17809012) as one such biomarker that was significantly associated with the analgesic effect of morphine. The current study measured the plasma concentrations of chemokines/cytokines in pre-treatment plasma samples of a total of 138 patients who were randomized to receive morphine (n=70) or oxycodone (n=68).

"Diagnose, Treat, and SUPPORT". Clinical competencies in the management of older adults with aspiration pneumonia: a scoping review.

Background: Aspiration pneumonia in older adults is increasingly common, with a high care burden and morbidity. However, clinical competencies in its management have not been developed, and healthcare professionals struggle on how to care for these patients with multimodal treatment needs. Therefore, we conducted a scoping review to investigate what is known about the desired clinical competencies for the management of older adults with aspiration pneumonia, to utilise in clinical practice, education, and future research.

Novel single nucleotide polymorphism biomarkers to predict opioid effects for cancer pain.

There have been few studies on predictive biomarkers that may be useful to select the most suitable opioids to optimize therapeutic efficacy in individual patients with cancer pain. We recently investigated the efficacy of morphine and oxycodone using single nucleotide polymorphisms (SNPs) of the catechol-O-methyltransferase () rs4680 gene as a biomarker (RELIEF study). To explore additional biomarkers that may enable the selection of an appropriate opioid for individual patients with cancer pain, three SNPs were examined: C-C motif chemokine ligand 11 (; rs17809012), histamine N-methyltransferase (; rs1050891) and transient receptor potential V1 (; rs222749), which were screened from 74 pain-related SNPs.

Morphine Versus Oxycodone for Cancer Pain Using a Catechol-O-methyltransferase Genotype Biomarker: A Multicenter, Randomized, Open-Label, Phase III Clinical Trial (RELIEF Study).

Background: We hypothesized that the high-dose opioid requirement in patients carrying the rs4680-GG variant in the COMT gene encoding catechol-O-methyltransferase would be greater for patients taking morphine than for those taking oxycodone, thus providing a much-needed biomarker to inform opioid selection for cancer pain.

Methods: A randomized, multicenter, open-label trial was conducted at a Japanese hospital's palliative care service. Patients with cancer pain treated with regular doses of nonsteroidal anti-inflammatory drugs or acetaminophen were enrolled and randomized (1:1) into morphine (group M) and oxycodone (group O) groups.

Work-related stress and coping methods of internists and primary care physicians during the COVID-19 pandemic in Japan: A mixed-method study.

Background: The COVID-19 pandemic has affected the mental health of health care workers. This study aimed to investigate the stress factors that cause burnout in Japanese physicians and their coping methods during the COVID-19 pandemic.

Methods: We conducted a sequential explanatory mixed-method study to investigate the psychological responses of physicians in the early stages of the pandemic.

Prevalence of Burnout among Internal Medicine and Primary Care Physicians before and during the COVID-19 Pandemic in Japan.

Objective To evaluate the change in the prevalence of burnout during the COVID-19 pandemic among internists and primary care physicians in Japan, and to identify factors associated with the exacerbation of burnout among these populations during this period. Methods This was a cross-sectional study based on two web-based surveys conducted in January 2020 (before the declaration of the COVID-19 pandemic) and June 2020 (during the pandemic). The participants were internists and primary care physicians of the Japanese Chapter of the American College of Physicians.

Efficacy of acceptance and commitment therapy for people with type 2 diabetes: Systematic review and meta-analysis.

Aims/introduction: This systematic review and meta-analysis aimed to investigate the efficacy and safety of acceptance and commitment therapy (ACT) for people with type 2 diabetes mellitus.

Materials And Methods: Several electronic databases were examined on 16 January 2021, including PubMed, CENTRAL, PsycINFO, International Clinical Trials Registry Platform and ClinicalTrials.gov.

A model six-month workshop for developing systematic review protocols at teaching hospitals: action research and scholarly productivity.

Background: Research engagement contributes to the improvement of patient care. A systematic review is a suitable first scholarly activity because it entails summarization of publicly available data and usually requires neither rigorous ethical review nor research funding.

Methods: This study aimed to develop a model workshop for healthcare staff to acquire skills in creating systematic review protocols based on their own clinical questions at teaching hospitals.

Additive Duloxetine for Cancer-Related Neuropathic Pain Nonresponsive or Intolerant to Opioid-Pregabalin Therapy: A Randomized Controlled Trial (JORTC-PAL08).

Context: Although opioids and pregabalin are widely used for cancer-related neuropathic pain (CNP), no clinical trials exist to determine which medications are effective when an opioid-pregabalin combination therapy fails.

Objectives: We investigated the efficacy of duloxetine for CNP nonresponsive or intolerant to opioid-pregabalin combination therapy.

Methods: A multicenter, randomized, double-blind, placebo-controlled trial was performed at 12 specialized palliative care services in Japan.

[Improvement of Pain Control after Dealing with Chemical Coping-A Case of Local Recurrence of Rectal Cancer].

A 57-year-old female underwent abdominoperineal resection for rectal cancer. Although she received postoperative adjuvant chemotherapy, she had presacral recurrence with pain 26 months postoperatively. We provided palliative care in parallel with systemic chemotherapy, but she had difficulty controlling pain despite using high-dose opioids at 43 months after surgery.

Avoiding diagnostic errors in psychosomatic medicine: a case series study.

Background: Non-organic lesions or diseases of unknown origin are sometimes misdiagnosed as "psychogenic" disorders or "psychosomatic" diseases. For the quality of life and safety of patients, recent attention has focused on diagnostic error. The aim of this study was to clarify the factors that affected misdiagnoses in psychosomatic medicine by examining typical cases and to explore strategies that reduce diagnostic errors.

Incidence of carnitine deficiency in patients with cancer pain: A pilot study.

Carnitine deficiency is reportedly associated with increased pain sensation in diabetes mellitus and fibromyalgia, but the association between serum carnitine concentration and cancer pain has not been fully elucidated. We investigated the incidence of carnitine deficiency in patients with cancer pain, and examined the effect of the patients' demographic and clinical characteristics on pain intensity and carnitine deficiency. The serum carnitine concentration was measured in 50 patients with cancer pain receiving non-steroidal anti-inflammatory drugs, but not opioids.

Gender differences in cancer-related distress in Japan: a retrospective observation study.

Background: Cancer care is currently the most important medical issue in Japan. Total pain of cancer patients consists of a combination of four factors: physical, psychological, social distress, and spiritual pain. Previous studies showed female cancer patients ask for more psychological support and seem to suffer different types of distress compared with male patients, for example, appearance-related symptoms.
