Most studies associated diabetes mellitus (DM) with risk of cancer have focused on the Caucasian population and only a few types of cancer. Therefore, a large and comprehensive nationwide retrospective cohort study involving an Asian population was conducted to evaluate the risk of several major types of cancer among Type 2 DM patients. The study analyzed the nationwide population-based database from 1996 to 2009 released by the National Health Research Institute in Taiwan. Incidence and hazard ratios (HRs) were calculated for specific types of cancer. The overall risk of cancers was significantly greater in the DM cohort [N 5 895,434; HR 5 1.19, 95% confidence interval (CI) 5 1.17-1.20], compared with non-DM controls (N 5 895,434). Several organs in the digestive and urogenital systems showed increased risk of cancer. The three highest HRs were obtained from cancers of the liver (HR 5 1.78, 95% CI 5 1.73-1.84), pancreatic (HR 5 1.52, 95% CI 5 1.40-1.65), and uterus and corpus (HR 5 1.38, 95% CI 5 1.22-1.55). The risk increased with age, and men with DM aged 75 years exhibited the highest risk (HR 5 7.76, 95% CI 5 7.39-8.15). Subjects with DM in this population have a modest increased risk of cancer, similar to the Caucasian population for several specific types of cancer. Old men with DM have the highest risk of cancer. Careful screening for cancer in DM patients is important for early diagnosis and effective treatment.
Previous case-control studies of Caucasian ethnicity have reported the association of adhesive capsulitis (AC) with diabetes mellitus (DM). To further investigate the risk of AC in subjects with DM in an Asian population, we performed the present cohort study featured the analyses of a randomly selected sub-dataset of one million individuals insured by the Taiwan National Health Insurance for the period spanning 1996-2008. The study and comparison cohorts consisted of 5,109 newly diagnosed diabetic patients and 20,473 randomly selected non-diabetic subjects aged ≥ 20 years in the year 2000. Both cohorts were followed up until December 2008 to measure AC incidence. We found that the incidence density of AC in the DM cohort was 3.08 times that of the comparison cohort (146.9 vs. 47.7 per 10,000 person-years), and rate ratios varied from 1.23 to 4.98 by categorized sociodemographic factors and comorbidity. The hazard ratio (HR) of AC for DM subjects remained significantly higher than that for non-DM subjects (p < 0.001) in all models. The HR increased in older age-groups (p < 0.001) and females (p < 0.001). Hyperlipidemia consistently increases the risk of AC in both univariate (HR = 2.67, 95% confidence interval (CI) 2.36-4.06) and multivariate analyses (HR = 1.29, 95% CI 1.11-1.49). In this eight-year study period, we found that DM and accompanying hyperlipidemia were independent risk factors for AC. The risks are higher for older-aged women. Findings in the present study help to identify high-risk patient groups to exercise early prevention of AC and enhance comprehensive care quality of DM subjects.
Similar unilateral neck and upper limb symptoms are often due to various entrapment neuropathies; carpal tunnel syndrome (CTS) and cervical radiculopathy (CR) are common causes among them. Therefore, we investigated the clinical characteristics and electrodiagnostic features of patients with carpal tunnel syndrome, cervical radiculopathy, and both conditions, called double crush syndrome (DCS). The medical records and electrodiagnostic reports of 866 patients with suspected CTS and CR visited a tertiary-care hospital were retrospectively analyzed. After excluding 101 patients with confounding conditions, 151 (20%) patients were diagnosed to have sole cases of CTS; 362 (47%) patients were diagnosed to have sole cases of CR; 198 (26%) patients were diagnosed to have DCS, while 54 (7%) patients had mere symptoms. Sole cases of CR had the highest incidences of neck pain, upper back pain, wrist and hand weakness. Female patients had the highest incidences of all the diseases in their sixth decade. Male patients had comparably distinguished high occurrence of all the diseases in their fifth to sixth decades. Although comparison of nerve conduction studies between patients with mere symptoms and patients with sole cases of CTS or DCS showed statistical differences, comparison between the latter two revealed no difference. We found most patients referred for electrodiagnostic studies had cervical radiculopathy. High concomitant occurrence of CTS and CR suggests cautious evaluation of patients with upper limb symptoms is important, because the management of these conditions is quite different.
Acupuncture and electroacupuncture treatments of symptomatic carpal tunnel syndrome (CTS) may improve symptoms and aid nerve repair as well as improve sensory and motor functions. However, limited evidence is available regarding the effects of these treatments based on comprehensive evaluation methods. This research completed the treatment and evaluation of 26 patients with confirmed CTS. Participants were divided into two treatment groups based on a modified neurophysiological grading scale. Of the total number of participants, 15 received acupuncture and 11 received electroacupuncture on both upper limbs. Acupoints were PC-7 (Daling) and PC-6 (Neiguan) along the pericardial meridian compatible with the median nerve tract. The treatment program consisted of 24 sessions of 15 min duration over 6 weeks. After electroacupuncture treatments, symptom severity was evaluated using the short clinical questionnaire by Lo and Chiang, which indicated improvements in the respective symptom severity score. After the acupuncture treatment, grip strength in the major symptomatic side in CTS patients could be significantly increased. Electrophysiology evaluation likewise indicated a significant increase in the distal median motor amplitude of the palm-wrist segment. In addition, Tinel's sign significantly decreased in the major symptomatic side. Our findings indicated that electroacupuncture could improve symptomatology, while acupuncture could exert positive therapeutic effects for CTS patients, as evidenced by improved symptomatology, grip strength, electrophysiological function, and physical provocation sign.
We recommend using the PH model for predicting mean LOS when the PH assumption for patients with different clinical characteristics is satisfied. However, the proposed method only applies to rehabilitating stroke patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
