Dairy Product Intake Is Inversely Associated with Metabolic Syndrome in Korean Adults: Anseong and Ansan Cohort of the Korean Genome and Epidemiology Study

The objective of this study was to examine the relationship between dairy product intake and the incidence of metabolic syndrome (MetS) and its components among middle-aged Koreans. We examined 7,240 adults aged 40-69 yr without MetS at baseline over a 45.5-month follow-up period. They were taken from the Anseong and Ansan cohort of the Korean Genome and Epidemiology Study. Dairy product intake including milk, yogurt, and cheese was assessed with food frequency questionnaire. At the follow-up, the incidence of MetS was 17.1%. The incidences of MetS components were as follows: low HDL cholesterol (16.2%), abdominal obesity (14.0%), hypertriglyceridemia (13.8%), hyperglycemia (13.3%), and hypertension (13.1%). Adjusting for potential confounders, dairy product consumption frequency was inversely associated with the risk of MetS and abdominal obesity. Hazard ratio (HR) (95% confidence interval) for dairy product consumption more than 7 times/week compared to never was 0.75 (0.64-0.88, P for trend < 0.001) for MetS and 0.73 (0.61-0.88, P for trend < 0.001) for abdominal obesity. HR for milk intake was 0.79 for MetS and 0.82 for abdominal obesity. The results of this study suggest that daily intake of dairy products protects against the development of MetS, particularly abdominal obesity, in middle-aged Koreans.     

Morbidity and Mortality in Jeju Residents over 50-Years of Age with Hip Fracture with Mean 6-Year Follow-Up: A Prospective Cohort Study

This prospective cohort study was performed to estimate the morbidity and mortality with 790 patients over 50-yr of age that sustained a femoral neck or intertrochanteric fracture from 2002 to 2006, followed-up for a mean of 6 yr (range, 4 to 9 yr). Crude and annual standardized mortality ratios (SMRs) were calculated; and mortalities in the cohort and the age and sex matched general population were compared. The risk factors on mortality and activities pre- and post-injury were assessed. Accumulated mortality was 16.7% (132 patients) at 1 yr, 45.8% (337 patients) at 5 yr, and 60% (372 patients) at 8 yr. SMR at 5 yr post-injury was 1.3 times that of the general population. Multivariate analysis demonstrated that age (OR, 1.074; 95% CI, 1.050-1.097; P<0.001), woman (OR, 1.893; 95% CI, 1.207-2.968; P=0.005), and medical comorbidity (OR, 1.334; 95% CI, 1.167-1.524 P<0.001) were independently associated with mortality after hip fracture. Only 59 of the 150 patients (39.3%) who were able to ambulate normally outdoors at preinjury retained this ability at final follow-up. Patients with a hip fracture exhibits higher mortality at up to 5 yr than general population. Age and a preinjury comorbidity are associated with mortality.     

VPL-DBS on neuropathic pain rat model is effective in mechanical allodynia than cold allodynia

Recently, deep brain stimulation (DBS) is widely used in various types of neurodegenerative disorders for minimal invasiveness and safety of the procedure. Deep brain stimulation is consistently applied for the treatment of patients with neuropathic pain even though the success rate is not as high as other neurodegenerative disorders. Furthermore, it is also unclear how DBS improves neuropathic pain. In this study, we investigated the role of DBS following the stimulation parameter for analgesic effect on mechanical allodynia and cold allodynia in neuropathic pain rats. We used a sciatic nerve injury model to induce neuropathic pain, and observed responses to mechanical and cold stimulation by the von Frey test and acetone test, respectively. We classified the rats into four groups: na?ve (na?ve, n?=?10), na?ve?+?DBS (N?+?DBS, n?=?10), neuropathic pain (NP, n?=?10), and neuropathic pain?+?DBS (NP?+?DBS, n?=?10). We inserted the DBS electrode into the ventral posterolateral nucleus (VPL) into the rats (VPL-DBS). The score for mechanical allodynia was significantly decreased in NP?+?DBS group (p?<?0.01). However, the score for cold allodynia did not significantly drop in any groups including NP?+?DBS group (p?>?0.05). In this study, we found that the electrical stimulation of the VPL works more effectively with mechanical allodynia than cold one, and pain signal induced by mechanical stimulus and cold stimulus may be processed through different pathways in the brain.     

Sonoelastographic lesion stiffness: preoperative predictor of the presence of an invasive focus in nonpalpable DCIS diagnosed at US-guided needle biopsy

Objectives  

To retrospectively evaluate whether sonoelastographic evaluation could help predict the presence of an invasive focus in nonpalpable DCIS diagnosed at US-guided needle biopsy.     

Intracranial transthecal subarachnoid fat emboli and subarachnoid haemorrhage arising from a sacral fracture and dural tear

We present the case of a 28-year-old man with an unusual aetiology of lipid-dense material in the subarachnoid space. CT of the head at presentation was normal. MRI of the spine revealed a defect in the dura at L5/S1, with avulsed left L5 and S1 nerve roots. Haematoma and marrow fat were observed in close relation to the dural tear adjacent to the sacral fracture. Head CT and MRI subsequently demonstrated new lipid-dense material and haemorrhage in the subarachnoid space after sacral instrumentation, presumably owing to transthecal displacement of fatty marrow.The presence of fat droplets within the subarachnoid space is an unusual finding and is most commonly the sequelae of a ruptured dermoid. We present a unique case with CT and MRI that demonstrates the development of subarachnoid fat emboli and subarachnoid haemorrhage secondary to pelvic trauma. A sacral fracture with an adjacent dural tear and nerve root avulsion is the putative source of the subarachnoid fat and blood.     

A Prospective Study on the Association Between Lower Urinary Tract Symptoms (LUTS) and Erectile Dysfunction: Results from a Large Study in Elderly Chinese in Southern China

IntroductionAlthough many cross-sectional studies have been conducted on the association between lower urinary tract symptoms (LUTS) and erectile dysfucntion (ED), no studies were prospective in Asia.AimThe relationship between LUTS and ED is examined using a prospective cohort of 2000 Chinese men.MethodsBaseline and 4-year data from a large prospective cohort study of 2000 Chinese elderly men were analyzed. A total of 1,736 subjects were included in the current analysis after excluding those with history of bladder or prostate cancer, or urological surgery, and those who used alpha blockers or anti-androgen.Main Outcome MeasuresLUTS were measured at baseline by the International Prostatic Symptom Score and ED was measured using one question on impotence at the end of 4 years.ResultsA dose–response relationship was observed for the relationship between baseline severity of LUTS and severity of ED at follow-up with those who had more severe LUTS at baseline with an increased odds of having more severe ED (odd ratio [OR] = 1.86, confidence interval [CI]: 1.16–2.97 for mild LUTS at baseline; OR = 2.95, CI: 1.81–4.81 for moderate LUTS at baseline; and OR = 3.82, CI: 2.00–7.27 for severe LUTS at baseline). Other baseline factors that were statistically significantly associated with ED included body mass index (OR = 1.13, CI: 1.01–1.26), hypertension (OR = 1.30, CI: 1.02–1.65) and diabetes (OR = 1.44, CI: 1.07–1.93).ConclusionThe presence of LUTS is associated with ED with more severe LUTS being associated with higher degree of ED in men.
