Purpose:
Numerous studies have produced conflicting findings regarding the efficacy of statins in prostate cancer treatment. Our objective was to examine the correlation between statin usage and clinical outcomes in Taiwanese men with de novo metastatic prostate cancer.
Materials and Methods:
We identified patients diagnosed with de novo metastatic prostate cancer from the Chang Gung Research Database spanning the years 2007 to 2020. To minimize confounding bias, we employed the inverse probability of treatment weighting (IPTW) method. Clinical outcomes were assessed using IPTW-adjusted Kaplan-Meier curves. Multivariate Cox proportional hazard regression analysis was utilized to evaluate the association between mortality and clinical factors.
Results:
The study cohort comprised 1,716 statin users and 276 non-users. Patients who used statins exhibited a longer median overall survival (85.4 months compared to 58.2 months; p=0.001) and cancer-specific survival (112.6 months compared to 75.7 months; p<0.001) compared to non-users. The median time to the development of castration-resistant status was similar between statin users and non-users (p=0.069). Multivariable Cox proportional hazards regression analysis, after IPTW adjustment, demonstrated that statin use was associated with improved overall survival.
Conclusions
Our study indicates that the use of statins following a de novo metastatic prostate cancer diagnosis enhances survival outcomes. However, statins did not appear to delay the onset of castration-resistant status. Further large-scale and long-term studies are warranted to investigate the biological effects of statins in men with prostate cancer.

Objective To study the sero-epidemiological starus regarding Rickettsia (R.) typhi,Bartonella (B.) henselae and Orientia (O.) tsutsugamushi in farmers from rural areas of Tianjin.Methods Field epidemiological surveys were performed in 8 districts (county) of Tianjin city from 2007 to 2009.886 farmers were randomly recruited and their serum samples collected to detect the specific antibodies of R.typhi,B.henselae and O.tsutsugamushi by micro-indirect immunoflorescence (IFA).Results The total antibody positive rates of R.typhi increased from 5.0% to 58.2% while B.heaselae had an increase from 2.6% to 14.5% and O.tsutsugamushi increased from 1.8% to 39.8%.Geographic distribution showed that farmers living in the central and southeast areas were higher than that in other areas.Conclusion Infections of both R.typhi,B.henselae and O.tsutsugamushi in farmers from Tianjin areas were popular and the antibody positive rates ofR.typhi,B.henselae and O.tsutsugamushi had an annual increase.

OBJECTIVETo evaluate the efficacy and safety of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA), and to compare the prognosis between patients of different ages.
METHODSThe hospitalization and follow-up data of 81 AAA patients treated by EVAR from May 2005 to May 2011 were retrospectively analyzed. All the patients were divided into advanced age group (age ≥ 75 years, 24 cases) and relatively young group (age < 75 years, 57 cases). General conditions, comorbidity, procedure, in-hospital complications, and follow-up were compared between these two groups.
RESULTSAll covered stents were successfully deployed, a technical success rate of 91.4% (74/81) was achieved. There was no intraoperative death. In-hospital mortality was 1.2% (1/81). The follow-up rate was 91.4% (74/81), with a mean follow-up of 47.5 months. Twelve deaths were recorded during follow-up, 1, 2, 3, 4, and 5-year survival rates were 98.6%, 92.2%, 80.8%, 58.7%, and 44.1%, respectively. When compared with relatively young group, the advanced age group had a lower rate of abdominal pain as the major symptom, but a higher rates of renal diseases and coronary artery diseases. Furthermore, the advanced age group had a longer stay in intensive care unit and higher morbidity of endoleaks, and also tended to have increased rates of pulmonary infection and access site hematoma, while the other parameters were similar between the two groups.
CONCLUSIONSEVAR of AAA is less invasive, safe, and effective during short to mid-tern follow-up. The patients of advanced age suffer from higher rates of some complications, thus careful perioperative preparation and intensive monitor are mandatory for preventing or treating potential complications and improving prognosis for these patients.

OBJECTIVEIn mid-July 2005, five patients presented with septic shock to a hospital in Ziyang city in Sichuan, China, to identify the etiology of the unknown reason disease, an epidemiological, clinical, and laboratory study were conducted.
METHODSAn enhanced surveillance program were established in Sichuan, the following activities were introduced: active case finding in Sichuan of (a) laboratory diagnosed Streptococcus suis infection and (b) clinically diagnosed probable cases with exposure history; supplemented by (c) monitoring reports on meningococcal meningitis. Streptococcus suis serotype 2 infection was confirmed by culture and biochemical reactions, followed by sequencing for specific genes for serotype and virulence factors.
RESULTSFrom June 10 to August 21, 2005, 68 laboratory confirmed cases of human Streptococcus suis infections were reported. All were villagers who gave a history of direct exposure to deceased or sick pigs in their backyards where slaughtering was performed. Twenty six (38%) presented with toxic shock syndrome of which 15 (58%) died. Other presentations were septicaemia or meningitis. All isolates were tested positive for genes for tuf, species-specific 16S rRNA, cps2J, mrp, ef and sly. There were 136 clinically diagnosed probable cases with similar exposure history but incomplete laboratory investigations.
CONCLUSIONAn outbreak of human Streptococcus suis serotype 2 infections occurred in villagers after direct exposure to deceased or sick pigs in Sichuan. Prohibition of slaughtering in backyards brought the outbreak to a halt. A virulent strain of the bacteria is speculated to be in circulation, and is responsible for the unusual presentation of toxic shock syndrome with high case fatality.
