Objectives: Bipolar hemiarthroplasty is commonly performed to treat displaced femoral neck fractures in osteo porotic patients. This study aimed to assess the occurrence and outcomes of unplanned return visits to the emergency department (ED) within 90 days following bipolar hemiarthroplasty for displaced femoral neck fractures. Methods: The clinical data of 1322 consecutive patients who underwent bipolar hemiarthroplasty for osteoporotic femoral neck fractures at a tertiary medical center were analyzed. Data from the patients’ electronic medical records, including demographic information, comorbidities, and operative details, were collected. The risk factors and mortality rates were analyzed. Results: Within 90 days after surgery, 19.9% of patients returned to the ED. Surgery-related reasons accounted for 20.2% of the patient’s returns. Older age, a high Charlson comorbidity index score, chronic kidney disease, and a history of cancer were identified as significant risk factors for unplanned ED visits. Patients with uncemented implants had a significantly greater risk of returning to the ED due to periprosthetic fractures than did those with cemented implants (P = 0.04). Patients who returned to the ED within 90 days had an almost fivefold greater 1-year mortality rate (15.2% vs 3.1%, P < 0.001) and a greater overall mortality rate (26.2% vs 10.5%, P < 0.001). Conclusions This study highlights the importance of identifying risk factors for unplanned ED visits after bipolar hemiarthroplasty, which may contribute to a better prognosis. Consideration should be given to the use of cemented implants for hemiarthroplasty, as uncemented implants are associated with a greater risk of peri prosthetic fractures.

OBJECTIVETo study the possible intervention of isoflavones in cytotoxicity induced by cadmium in vascular endothelial cells.

METHODSAn ECV 304 cell line derived from human umbilical vein endothelial cells was adopted. Genistein/daidzein was added prior to or simultaneously with CdCl2, cell viability was determined by MTT assay, and metallothionein mRNA expression was monitored by RT-PCR method.

RESULTSCell viability was higher in isoflavone and CdCl2 co-treated groups than that in CdCl2 treated group, with CdCl2 concentration at 10, 20, 40, and 80 micromol/L, respectively. However this increase was not observed in the group treated with CdCl2 at a concentration of 60 micromol/L. Isoflavones (10(-10) mol/L to 10(-5) mol/L) were added 24 h before cells were challenged with 80 micromol/L CdCl2 for 24 h or simultaneously with 80 micromol/L CdCl2. Genistein increased cell viability only at 10(-5) mol/L, while daidzein caused a dose-dependent increase from 10(-10) mol/L to 10(-5) mol/L in co-treatment with CdCl2. In pre-treatment, genistein (10(-7) to 10(-5) mol/L) increased cell viability whereas only 10(-5) mol/L of daidzein exerted protection. Apparent protection could be found when the cells were pre-treated with 10(-5) mol/L isoflavones for over 12 h, whereas 24 h incubation was required in such a co-treatment, with the exception of daidzein that had a significant protection in only 3 h. Isoflavones (10(-6) mol/L) incubated for 3 h to 24 h, increased MT IIA and MT IF mRNA expression, but the induction could not last for more than 24 h. Co-treatment with isoflavones could induce an additional induction of MT IIA mRNA expression in cells exposed to cadmium. However, the additional induction of MT IIA and MT IF mRNA was not seen when pre-treatment was carried out with isoflavones, with the exception of an increase in MT IIA mRNA expression in the daidzein pre-treated group.

CONCLUSIONGenistein/daidzein could reverse the cytotoxicity of cadmium either in pre-treatment or in co-treatment. The protection is the strongest in 10(-5) mol/L of isoflavones with a dose-dependent pattern. There are differences between genistein and daidzein in their protective effects. Whether the protection of isoflavones is related to their capacity of inducing MT mRNA expression remains to be elucidated.

OBJECTIVETo investigate the psychological impact of mastectomy on women with breast cancer.

METHODSQuestionnaires were answered by 90 patients after mastectomy for breast cancer. The data were collected and analyzed regarding the age, occupation, education, income and living place of the patients. Their psychological changes were compared and evaluated statistically using chi-square analysis.

RESULTSMastectomy caused psychological impact on half of the patients, which included fear of cancer, feeling of body incompleteness, inconvenience in working and social communication, less sexual act and low spirit. 79 percent of the patients considered breast reconstruction unnecessary. 54 percent did not know that the breast could be reconstructed. The patient feelings differed with the age, occupation, income and living place.

CONCLUSIONMastectomy hurts patient psychological health.

OBJECTIVETo investigate apoptosis and expression of heme oxygenase-1 (HO-1) induced by cadmium in human embryonic kidney cells (HEK239T).

METHODSThe MTT method was used for determining the cell proliferation activity. The apoptosis was determined by the flow cytometry. The HO-l mRNA expression and protein level were detected by RT-PCR method and Western blot respectively.

RESULTSThe ratios of apoptosis in HEK239T cells were 11.90% +/- 0.28%, 9.27% +/- 1.73%, 9.79% +/- 0.67% and 8 .97% +/- 1.60% at the concentration of 5.0, 10.0, 20.0 and 40.0 micromol/L CdCl(2) respectively, higher than those in the control group (6.69% +/- 0.46%) with the significant difference (P < 0.01). The CdCl(2) of between 10 and 40 micromol/L could highly induce the expression of HO-1 of the human embryonic kidney cells. The expression would increase slowly till the flat stage with the increase of the dosage and then would decrease slightly over time.

CONCLUSIONThe cadmium can induce the apoptosis of the human embryonic kidney cells and up-regulate the expression of HO-1.

Hospice and palliative care in Taiwan has been growing continuously. The 2015 Quality of Death index, as rated by the Economist Intelligence Unit, ranked Taiwan first among Asian countries and sixth in the world. In this review article, we highlight three particular areas that might have contributed to this success; the laws and regulations, spiritual care and research network. Finally, we discuss the future challenges and prospects for Taiwanese encounters. A systemic review was conducted with the keywords “hospice palliative care Taiwan” using PubMed. The passing of the “Natural Death Act” in 2000 set the example and established a landmark for patient autonomy in Asia; it guarantees the patient's right to request that medical staff do not resuscitate (DNR) them and to reject other futile medical treatments at the end of their life, thus reflecting the importance of palliative care from the policy perspective. In 2015, Taiwan passed another pioneering law entitled the “Patient Autonomy Act”. This law states that a patient may decline medical treatment according to his/her own will. Taiwanese indigenous spiritual care was launched in 2000. It requires a Buddhist Chaplain to successfully complete a training program consisting of lectures, as well as bedside practicum before applying Buddhist practices to end-of-life care. The Japan-Korea-Taiwan research network was established for the purpose of enabling collaborative research for the East-Asian collaborative cross-cultural Study to Elucidate the Dying process (EASED) cohort. With consensus from the government and society to make it a priority, hospice and palliative medicine in Taiwan has been growing steadily.

OBJECTIVETo study the clinical effects of self-invented cartilage-perichondrium autografting for the repair of articular cartilage defects, so as to reconstruct the joint surface.

METHODSAmong total 11 patients with hand injuries from Oct. 2005 to Oct. 2009, 7 patients were male and 4 patients were female, ranging in age from 17 to 50 years, with an average of 29 years. All the patients had serious injuries of finger joint and were treated with cartilage-perichondrium autografting. After the operation, function exercises were performed, and composite scores of joints at hand were used to evaluate therapeutic effects.

RESULTSAll the patients were followed-up from 1 to 4 years with an average of 24 months. The operation of all the patients were successful, and there were no infection. The mean score was (41.0 +/- 0.63) in 2 years after operation. Eight patients got an excellent result (> 38 scores), 2 good (from 35 to 38 scores) and 1 bad (< 30 scores).

CONCLUSIONThe cartilage-perichondrium autografting method is effective to reconstruct the defects of articular cartilage, and decrease the disablement rate of hand injuries.

OBJECTIVETo investigate the feasibility of metallothionein (MT) gene expression level in human peripheral blood lymphocytes (HPBLs) as a biomarker in cadmium exposure.

METHODSThe MT gene expression level in HPBLs of workers exposed to cadmium was examined using RT-PCR technique, and the exposure assessment and effect assessment were conducted in exposed workers.

RESULTSThe basal MT-1A, IE, IF, IX and MT-2A expression level in workers exposed to cadmium were significantly higher than those in the control group (P < 0.05). The basal MT-1A, IE, IF, IX and MT-2A expression level would be significantly increased with the increase of the blood cadmium (BCd) level (P < 0.05). There was a trend of increase for the mRNA expression of the basal MT-1A, 1E, IF, IX, MT-2A, especially for the mRNA expression of MT-1A and MT-2A (P < 0.05) with the increase of the level of the urine cadmium (UCd). There was a good dose-response relationship between basal MT-1A expression and UCd. The basal MT-1A, IE, IF, IX and MT-2A expression level were significantly correlated with BCd (P < 0.05) while the basal MT-1A, IF and MT-2A expression level were significantly correlated with UCd (P < 0.05). There were dose-effect relationships of BCd to the basal MT-1E, MT-1F, MT-1X and MT-2X expression level respectively and there were also dose-effect relationships of UCd, beta(2)-MG and the urine metallothionein to the basal MT-1A expression.

CONCLUSIONThe expression of the MT gene isoforms in HPBLs can serve as the biomarker for the cadmium exposure and MT-1A can also serve as the effective biomarkers for the cadmium-induced renal toxicity.

OBJECTIVETo investigate whether renal dysfunction induced by cadmium is related to plasma anti-metallothionein antibody (anti-MT Ab) in workers occupationally exposed to cadmium.

METHODSThe male workers in a smeltery were selected as the subjects for the exposure and effect assessment. The urine cadmium (UCd), the blood cadmium (BCd) and the occupational cadmium intake (TTCd) served as the exposure indexes while the urine beta(2) microglobulin (Ubeta(2)-MG), the N-acetyl-beta-D-glucosaminidase (UNAG) and the urine albumin concentration (UALB) served as the effect markers for the renal dysfunction caused by the cadmium. The titer of the plasma anti-metallothionein antibody was determined with the enzyme linked immunosorbent assay (ELISA).

RESULTSThe UCd (3.16 microg/g Cr), BCd (9.28 microg/L), Ubeta(2)-MG (81.17 microg/g Cr) and UALB (7.03 mg/g Cr) in the occupational cadmium exposure group were significantly higher than those in the control group and the Ubeta(2)-MG, UNAG and UALB as well as the occurrence rate of abnormality would be increased with the increase of the level of the occupational cadmium exposure. There was no significant difference in the titer of anti-MT Ab between the exposure group and the control group (P > 0.05). The titer of the anti-MT Ab would not be increased with the increase of the dosage of the exposure and had no significant correlation with BCd, UCd and TTCd (P > 0.05). The positive correlation were found between anti-MT Ab and UNAG as well as between anti-MT Ab and Ubeta(2)-MG in the exposure group with the correlation coefficient of 0.302 and 0.218 respectively. The workers with high level anti-MT Ab are more susceptible to cadmium nephrotoxicity than those with low anti-MT Ab with the odds ratio (OR) value of 4.200 and the 95% CI between 1.213 and 14.541 (P < 0.05).

CONCLUSIONThere is a dose-effect relationship between cadmium exposure and renal dysfunction in workers occupationally exposed to cadmium, but no correlation is found between cadmium exposure and plasma anti-MT Ab. The workers occupationally exposed to the cadmium with higher level of anti-MT Ab are easier to suffer from renal dysfunction caused by cadmium. Plasma anti-MT Ab could be used as a biomarker of susceptibility in the workers exposed to cadmium.

OBJECTIVETo study the characteristics of occupational exposure of polycyclic aromatic hydrocarbons (PAHs) in coke oven workers.

METHODSSamples were collected individually and PAHs concentration in the ambient air were assayed by high performance liquid chromatography (HPLC) and toxic equivalency factors (TEFs) were introduced to assess the carcinogenic potency.

RESULTSThe levels of PAHs occupational exposure in oven workers at topside was higher than at side oven and bottom oven (P < 0.05). Non-carcinogenic PAHs were more than 70% of total PAHs and benzo[a]pyrene accounted for 65.5% approximately 72.4% of total benzo[a]pyrene equivalents. Total occupational exposure level of PAHs in coke oven workers was positively related to the content of benzo[a]pyrene and pyrene, respectively (r(2) = 0.84, r(2) = 0.94, P < 0.05).

CONCLUSIONCoke oven workers were exposed to a high level of PAHs which possessed some extent of carcinogenic potency, and benzo[a]pyrene is the chief carcinogenic substance.

OBJECTIVETo study the role of cerebrovascular hemodynamic indexes (CVHI) changing in stroke and to provide reference for stroke prevention and risk factor study.

METHODSFrom 2003 to 2004, participants aged 40 years and above in two communities in Fengxian district were recruited by cluster sampling. Risk factors of stroke and CVHI were investigated and checked during baseline investigation. A total of 10 565 individuals completed the survey and met the inclusion criterion. After baseline investigation, the cohort was followed up for stroke occurrence. Relative risk (RR) of CVHI and common risk factors were estimated by cohort study design.

RESULTSAge of the cohort was (56.2 ± 11.4) years. 4444 (42.1%) were males and 6121 (57.9%) were females. Total follow-up duration was 67 885.7 person-years. A total of 195 stroke cases occurred and incidence density of stroke was 287.2 per 100 000 person-years. Stroke incidence in exposure groups of hypertension, heart disease and alcohol drinking was 3.47% (108/3118), 2.96% (21/710) and 2.50% (47/1882), respectively. The incidence in corresponding non-exposure group was 1.17% (87/7448), 1.77% (174/9855) and 1.70% (148/8683) respectively. There was significant difference between 2 groups (χ(2) value was 62.72, 4.56 and 4.94, respectively, P < 0.05). Stroke incidence in CVHI score < 25, 25 - 49, 50 - 74 and ≥ 75 groups was 9.12% (59/647), 5.68% (44/775), 2.52% (39/1545) and 0.72% (53/7403)(χ(2)trend = 273.57, P < 0.05), respectively. Incidence of stroke in 40 - 49, 50 - 59, 60 - 69, ≥ 70 years age group was 0.22% (8/3565), 1.28% (43/3357), 2.71% (50/1848) and 5.88% (94/1600) (χ(2)trend = 181.48, P < 0.05), respectively. Multiple Cox regression analysis indicated that RR (95%CI) value of hypertension and cigarette smoking was 1.40(1.02 - 1.92) and 1.59(1.19 - 2.12), respectively when comparing with non-exposure group. RR (95%CI) value in CVHI score < 25, 25 - 49 and 50 - 74 points group were 6.15 (4.08 - 9.26), 4.55 (2.98 - 6.96) and 2.68 (1.75 - 4.09), respectively when comparing with the score ≥ 75 points group. RR (95%CI) value in age 50 - 59, 60 - 69 and ≥ 70 years group was 4.61 (2.16 - 9.82), 7.81 (3.67 - 16.60) and 13.49(6.44 - 28.24), respectively when comparing with below 40 years group.

CONCLUSIONCVHI score is the strong independent predictive factor and hypertension, cigarette smoking and age are the independent risk factors of stroke.
