  • Background: Whether depression causes increased risk of the development of breast cancer has long been debated. We conducted an updated meta-analysis of cohort studies to assess the association between depression and risk of breast cancer. Materials and Methods: Relevant literature was searched from Medline, Embase, Web of Science (up to April 2014) as well as manual searches of reference lists of selected publications. Cohort studies on the association between depression and breast cancer were included. Data abstraction and quality assessment were conducted independently by two authors. Random-effect model was used to compute the pooled risk estimate. Visual inspection of a funnel plot, Begg rank correlation test and Egger linear regression test were used to evaluate the publication bias. Results: We identified eleven cohort studies (182,241 participants, 2,353 cases) with a follow-up duration ranging from 5 to 38 years. The pooled adjusted RR was 1.13(95% CI: 0.94 to 1.36; $I^2=67.2%$, p=0.001). The association between the risk of breast cancer and depression was consistent across subgroups. Visual inspection of funnel plot and Begg's and Egger's tests indicated no evidence of publication bias. Regarding limitations, a one-time assessment of depression with no measure of duration weakens the test of hypothesis. In addition, 8 different scales were used for the measurement of depression, potentially adding to the multiple conceptual problems concerned with the definition of depression. Conclusions: Available epidemiological evidence is insufficient to support a positive association between depression and breast cancer.

  • Background: Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Despite this, few papers have reported the incidence and independent risk factors associated with PONV in the context of oral and maxillofacial surgery (OMFS). Therefore, we sought to determine the incidence of PONV, as well as to identify risk factors for the condition in patients who had undergone OMFS under general anesthesia. Methods: A total of 372 patients' charts were reviewed, and the following potential risk factors for PONV were analyzed: age, sex, body mass index, smoking status, history of PONV and/or motion sickness, duration of anesthesia, amount of blood loss, nasogastric tube insertion and retention and postoperative opioid used. Univariate analysis was performed, and variables with a P-value less than 0.1 were entered into a multiple logistic regression analysis, wherein P-values < 0.05 were considered significant. Results: The overall incidence of PONV was 25.26%. In the multiple logistic regression analysis, the following variables were independent predictors of PONV: age < 30 years, history of PONV and/or motion sickness, and anesthesia duration > 4 h. Furthermore, the number of risk factors was proportional to the incidence of PONV. Conclusions: The incidence of PONV in patients who have undergone OMFS varies from center to center depending on patient characteristics, as well as on anesthetic and surgical practice. Identifying the independent risk factors for PONV will allow physicians to optimize prophylactic, antiemetic regimens.

  • Objectives: Depression is common in cancer patients. However, only limited evidence is available for Asian populations. The authors therefore examine the prevalence of depression in Thai patients with cancer. In addition, associated factors were determined. Methods: This cross-sectional study was conducted in cancer patients admitted to a university hospital during December 2006 - December 2007. The Patient Health Questionnaire (PHQ-9) was used to assess all cancer patients. Suicidal risk was assessed by using the Mini-International Neuropsychiatric Interview (MINI) in the module of suicidal risk assessment. Results: Of 108 cancer patients, 29.6 % were diagnosed with a depressive disorder (mild, 14.8 %; moderate, 5.6 %; severe, 9.3 %). However, only 25.0 % of these were recognized as being depressed by the primary physician. According to the MINI., 28.1 % of these depressed cancer patients had a moderate to severe level of suicidal risk. In addition, the findings suggest that increased risk of depression is significantly associated with increased pain score, lower number of cancer treatments (< 2 methods), increased educational duration (>13 years), increased age (> 50 years old) and being female. Conclusions: The prevalence of depression is high in Thai cancer patients. However, depressive disorder in those patients is frequently undiagnosed. It is associated with several factors including pain, a number of cancer treatments, education duration, age and sex. To improve quality of life, increase compliance with treatments and prevent of suicide, screening for depressive disorders in this patient group is strongly recommended.

  • 뇌졸중은 사망발생 및 장애를 일으키는 주요 원인 질환이며, 당뇨병은 뇌졸중의 주요 위험인자이다. 당뇨병 환자가운데 뇌졸중을 동반한 환자에서 적정 혈압 관리의 중요성을 알아보고자 한다. 제6기 국민건강영양조사 자료를 바탕으로 18세 이상 80세 미만자 총 16,389명을 대상으로 회귀분석을 통하여 당뇨병 유병기간에 따른 혈압조절을 통한 뇌졸중의 위험도를 산정하였다. 당뇨병 유무에 따른 뇌졸중의 유병률은 당뇨병 환자 군에서 높았고, 당뇨병의 유병기간이 길어질수록 고혈압과 뇌졸중의 위험도는 상승하였으며, 당뇨병과 고혈압에 대한 치료 비율은 높았다. 고혈압군에 비해 적정 혈압 유지군(<140/<90 mmHg)에서 뇌졸중 위험비(HR)는 0.57 낮았다. 당뇨병과 고혈압에 대한 치료가 동반됨에도 불구하고 고혈압의 빈도는 상승하였고, 당뇨병 유병기간 5년 이후 뇌졸중의 유병률이 상승함에 따라 이 시기의 효과적인 혈압관리가 더욱 중요하다. 당뇨병 환자에서 지속적으로 적정 혈압으로 관리함으로써 뇌졸중 위험도를 낮추는 것이 중요하다.

  • Exterior insulation board in cast-in-place concrete form system could reduce construction period and improve quality in apartment construction. However, the method is progressed with insulation and concrete frame works at the same time, then risk is increased in duration control and quality management. Therefore, this paper analyzed risk factors through FMEA method. We found that the key risk factors delaying schedule was insulation material that soaked in the rain and quality defects on the insulation material joint. Based on this research, the risk management approach should be developed for improvement of method activation.

  • 프로젝트 리스크관리는 프로젝트 착수에서 완공에 이르기까지 프로젝트 생애주기 동안 프로젝트의 범위, 비용, 일정 등에 영향을 미치는 위협 및 기회 요인을 포함하는 리스크를 사전에 식별하고 이에 대한 완화전략을 사전에 마련함으로서 프로젝트를 성공에 이르게 하는 효과적인 관리를 위해 활용된다. 프로젝트를 진행하는데 있어서 완공일이 지나기 전에 예산과 공사기간을 정확히 예측하는 것은 불가능하므로, 미국 워싱턴교통부에서는 사업비 규모에 따라 여러 분야의 전문가를 참여자로 하는 워크숍을 실시하게 함으로서 체계적인 리스크관리를 의무화하고 있다. 하지만 국내 건설 현장에서는 체크리스트 및 리스크분석 위주의 리스크관리만 이루어지고 있어 효율적인 관리가 이루어지지 않고 있다. 따라서 본 연구에서는 국내 A하천정비사업에 워크숍 기반 리스크관리기법을 국내 처음으로 적용해 봄으로서 국내 현실에 적합한 효율적인 리스크관리 방법을 제안하였다. 또한 이러한 리스크관리 전 과정에 식별된 리스크를 분석하여 완화전 후의 리스크에 대한 비교를 쉽게 살펴보고 관리할 수 있는 RBES 프로그램을 활용하였다. 그 결과 전체 사업비용과 공사기간의 증가 문제를 사전에 인지하고 이에 대한 실질적인 완화대책을 수립하게 함으로서 공사기간 지연효과를 미리 방지하는 효과가 있었다.

  • Objectives : The purpose of this study is to evaluate the correlation between HbA1c and pain intensity in diabetic peripheral neuropathy patients, and to compare the difference between two groups divided by the risk of complications. Methods : The participants were 46 men and women suffering from neuropathic pain diagnosed with diabetes mellitus who visited the Hospital of Traditional Korean Medicine, Semyung University from June, 2014 to August, 2015. Age, duration of diabetes mellitus, numeric rating scale(NRS), and Michigan neuropathy screening instrument(MNSI) were used as evaluation tools. Results : 1. In all 46 cases, there were no significant correlations between HbA1c and age, duration of diabetes mellitus, NRS, MNSIQ, or MNSIE. 2. Among 23 cases with a high risk of complications (more than 7.0 % of HbA1c, group A), there were no significant correlations between HbA1c and age, duration of diabetes mellitus, NRS, MNSIQ, or MNSIE. 3. Among 23 cases with a low risk of complications(less than 7.0 % of HbA1c, group B), there were no significant correlations between HbA1c and age, duration of diabetes mellitus, NRS, MNSIQ, or MNSIE. 4. Means of duration of diabetes mellitus, NRS, MNSIQ, and MNSIE were higher in group A than group B, but there were no significant correlations in statistics. Conclusions : This study could not find statistically significant correlations between pain intensity and HbA1c in diabetic peripheral neuropathy patients, so more studies are required in the future.

  • Purpose: The aim of this study was to investigate the incidence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) after tooth extraction in patients with osteoporosis on oral bisphosphonates in Korea and to evaluate local factors affecting the development of BRONJ. Materials and Methods: The clinical records of 320 patients who underwent dental extraction while receiving oral bisphosphonates were reviewed. All patients had a healing period of more than 6 months following the extractions. Each patient's clinical record was used to assess the incidence of BRONJ; if BRONJ occurred, a further radiographic investigation was carried out to obtain a more definitive diagnosis. Various local factors including age, gender, extraction site, drug type, duration of administration, and C-terminal telopeptide (CTx) level were retrieved from the patients' clinical records for evaluating their effect on the incidence of BRONJ. Results: Among the 320 osteoporotic patients who underwent tooth extraction, 11 developed BRONJ, reflecting an incidence rate of 3.44%. Out of the local factors that may affect the incidence of BRONJ, gender, drug type, and CTx level showed no statistically significant effects, while statistically significant associations were found for age, extraction site, and duration of administration. The incidence of BRONJ increased with age, was greater in the mandible than the maxilla, and was associated with a duration of administration of more than 3 years. Conclusion: Tooth extraction in patients on oral bisphosphonates requires careful consideration of their age, the extraction site, and the duration of administration, and close postoperative follow-up should be carried out to facilitate effective early management.

  • Lung cancer is one of the most common malignancies in the world. Its incidence and mortality rates are on the rise in Pakistan. However, epidemiological studies to identify common lung cancer determinants in the Pakistani population have been limited. In this study, data of 440 cases and 323 controls were collected from different hospitals in Peshawar and Islamabad, along with information about socio-demographic factors including age, sex and smoking. Univariate and multi-factorial analyses of socio-demographic factors in association with each other were also performed. Overall survival analysis highlighted that, out of 440 patients in the lung cancer dataset, 204 people were uncensored with a median survival time of 13 months (95% CI=12-18). There were 41 femaleand 399 male patients. Differences were observed between length of survival in the males and females (${\chi}12$ = 6.1; p-value = 0.01). Gender was observed to be significantly related to survival (p-value< 0.01), with better survival in females (hazard ratio=2). Cox regression was extended to adjust for the covariate age (z = 2.5; p-value = 0.02). Survival analysis was also performed on the basis of smoking groups (current smokers, former smokers and never smoked individuals) and smoking duration (smoking duration >10 years, <10 years and never smoked). Smoking duration was significantly associated with survival (p-value < 0.01), with better survival in never smokers in comparison to both smoking for greater or less than 10 years. Strong associations were observed for smoking group with duration greater than 10 years, OR=6.1(3.9-9.5) on univariate and multifactorial analysis OR=11.3(CI=6.8-19.3).
