Serum Total Cholesterol Levels Would Predict Nosocomial Infections After Gastrointestinal Surgery

It has been suggested that total cholesterol levels and the use of statin medications are associated with the incidence of complications after gastrointestinal surgery. The aim of this study was to determine if preoperative total cholesterol levels are associated with a higher risk of postoperative infections and mortality. A total of 2211 patients undergoing general surgical procedures between December 2006 and November 2008 at Iizuka Hospital and between January 2010 and March 2012 at Jichi Medical University Hospital were reviewed. Multiple logistic regression models were used to evaluate serum total cholesterol and other variables as predictors of postoperative nosocomial infections. Serum total cholesterol concentrations lower than 160 mg/dl were associated with an increased incidence of superficial and deep incisional surgical site infections. Serum total cholesterol levels showed a reverse J-shaped relationship with the development of organ space surgical site infection and pneumonia. There was no discernible effect of serum cholesterol levels on the postoperative mortality observed in this cohort of patients. Decreased serum albumin was one of the strongest risk factors for the development of nosocomial infection after surgery. Postoperative pneumonia was not observed in patients taking statin medications whose cholesterol levels were <200 mg/dl. Serum total cholesterol may be a valid predictor of surgical outcome. Preoperative statin use may affect the development of postoperative pneumonia in patients with total cholesterol levels below 200 mg/dl.     

Noninvasive diagnosis of dual AV nodal physiology in patients with AV nodal reentrant tachycardia by adenosine triphosphate test

Atrioventricular nodal reentrant tachycardia (AVNRT) is a relatively common paroxysmal supraventricular tachycardia. This study investigated whether adenosine-5'-triphosphate (ATP) injection during sinus rhythm might be useful in the noninvasive diagnosis of dual AV nodal pathways. The study group consisted of 9 patients with slow/fast AVNRT and 11 control patients without antegrade dual AV nodal physiology (DAVNP). ATP (2.5 to 30 mg, in 2.5-mg increments was injected during sinus rhythm until signs of DAVNP (> or = 50 msec increase or decrease in AH or PR interval in two consecutive beats) or > or = second-degree AV block was observed. DAVNP was diagnosed by ATP test in all 9 patients with slow/fast AVNRT. DAVNP was observed by ATP test in 3 of the 11 control patients. Thus, the test had a sensitivity of 100% and specificity of 73%. ATP test given during sinus rhythm is useful for identifying patients with dual AV nodal pathways who are prone to AVNRT.     

Successful Unrelated Cord Blood Transplantation for Epstein-Barr Virus-Associated Lymphoproliferative Disease with Hemophagocytic Syndrome

We report a case of successful umbilical cord blood transplantation (CBT) for Epstein-Barr virus (EBV)-associated lymphoproliferative disease (LPD) in a 6-year-old girl. The patient had hemophagocytic syndrome with excessive circulating levels of EBV DNA that was refractory to immunochemotherapy. Multiple hepatosplenic lesions favored the diagnosis of EBV-associated LPD, although the aggressive course precluded the histopathologic diagnosis. Unrelated CB cells mismatched at 1 HLA locus were infused after patient conditioning with 900 mg/m2 etoposide, 2 g/m2 cytarabine, 16 mg/kg busulfan, and 200 mg/kg cyclophosphamide. Complete chimeric status was obtained on day 19 posttransplantation. Drug fever and acute graft-versus-host disease of the skin (grade II) were the major complications. A transient increase of EBV DNA 1 year after CBT indicated a primary EBV infection of the donor cells. The patient is alive with no evidence of disease 27 months after CBT. There has been no previous report of successful CBT for EBV-related LPD/lymphoma. CBT can be a curative treatment for the disease, even if no viral memory has been set in the stem cell source.     

Squamous differentiation and prognosis in upper urinary tract urothelial carcinoma

Squamous differentiation is the most common histological variation in urothelial carcinoma (UC). However, the clinical significance of squamous differentiation in upper urinary tract UC is unclear. To investigate the significance of squamous differentiation, hematoxylin and eosin stained slides from 140 patients with upper urinary tract UC who underwent nephroureterectomy were reviewed by a single pathologist and the presence of squamous differentiation was recorded. Squamous differentiation was observed in 23 out of 140 studied cases (16%). Squamous differentiation significantly correlated with several adverse prognostic factors including histological grade 3 tumors, presence of lymphovascular invasion, concomitant carcinoma in situ, advanced tumor stage, and occurrence of lymph node metastasis. The Kaplan-Meier and univariate Cox regression analyses revealed that the presence of squamous differentiation was significantly associated with shorter metastasis-free survival [log-rank P = 0.030; univariate hazard ratio (HR), 2.30; 95% confidence interval (CI), 1.06-4.99], cancer-specific survival (log-rank P = 0.0024; univariate HR 3.34; 95% CI, 1.47-7.85), and overall survival (log-rank P = 0.018; univariate HR 2.39; 95% CI, 1.13-5.06) after nephroureterectomy. However, in multivariate analyses, squamous differentiation was not significantly associated with patient outcomes. These findings suggest that squamous differentiation is associated with disease progression, but is not an independent predictor of a worse prognosis in patients with upper urinary tract UC.     

An analysis of and new risk factors for reexpansion pulmonary edema following spontaneous pneumothorax

Background

The major risk factor for reexpansion pulmonary edema (RPE) following the treatment of spontaneous pneumothorax is thought to be chronic lung collapse. However, a long-term collapsed lung does not always cause RPE. The purpose of this study was to define other risk factors for RPE among patients undergoing drainage for the treatment of spontaneous pneumothorax.

Methods

We retrospectively reviewed all the patients with spontaneous pneumothorax who had been treated at our hospital during a 5-year period. The duration of symptoms, location and size of the pneumothorax, size of the chest tube, and pleural effusion, which can occur coincidentally with pneumothorax, were compared in patients who did and did not experience RPE.

Results

Forty patients were underwent drainage for the treatment of a spontaneous pneumothorax between January 2007 and December 2012. RPE developed in 13 of the 40 (32.5%) patients. In the multivariate analysis, the presence of pleural effusion coincident with pneumothorax contributed to the risk for RPE [odds ratios (OR), 1.557; 95% confidence intervals (CI), 1.290-1.880]. The duration of symptoms, location and size of the pneumothorax and size of the chest tube were similar between the groups. Symptomatic RPE was associated with a larger pneumothorax size.

Conclusions

The rate of RPE following spontaneous pneumothorax is higher than was previously reported. Our findings suggest the presence of pleural effusion coincidentally with pneumothorax may therefore be a new risk factor for RPE.     

Tuberculosis care and new horizon of Japanese society

Current tuberculosis (TB) problems are reflections of Japanese society. Living or dying alone among the elderly, difficulty in finding jobs or withdrawal into themselves among the youths are features of modem society. The future needs for TB care were discussed on specific topics of TB among the elderly, foreigners and the homeless. Presenters showed the importance of the patient-centered care in collaboration with public health and welfare services. Both patients and staffs will see others shining, as they touch each other in the deep part of human existence. A diabetic ex-TB patient talked his experience in his treatment. His window of mind was gradually opened from inside with the continuous support in DOTS by the staff of the public health center. To accumulate these experiences of a heartwarming atmosphere will have the effective power on establishment of social supporting systems. This symposium can be a step towards humanized society or a new horizon of public health which can answer to another need of inner cry of a sick people particularly among the socially disadvantaged who are the victims of the weakness of society. 1. Current situation and issues of elderly tuberculosis patients: Eriko SHIGETO (NHO Higashihiroshima Medical Center). By the analysis of 102 tuberculosis patients of 70 years old and above who were registered at Hiroshima Prefectural Health Center in 2009, 41 patients had severe complications such as diabetes mellitus, renal insufficiency, malignancy or cerebrovascular disorder. Their prognosis was rather poor and the ADL tended to be worsened during hospitalization. Though 16 of the 34 deaths were caused with non-tuberculosis diseases, the ratio of the tuberculosis deaths was higher (4/17) among the patients living alone. Sufficient care of the elderly for early diagnosis, care system to treat various complications and patient support are required. 2. Provision of medical interpreters to help foreigners with tuberculosis in Tokyo: Takashi SAWADA (Services for Health in Asian & African Regions (SHARE)). In 2006, Tokyo Metropolitan Government started to dispatch interpreters for foreigners to strengthen DOTS program. Collaboration with NGOs made it possible to train 37 volunteer interpreters, and to provide services in 13 languages, as of 2010. In Japan, the treatment defaulter rate among non-Japanese tuberculosis patients had been remarkably high. But with having the assistance of interpreters, the treatment completion rate has become higher than 80%. It is recommended to expand a similar system to other part of Japan, as the proportion of foreigners among total tuberculosis cases keeps on increasing nationwide. 3. Tuberculosis problems in Japan from the view point of homelessness-through the activities of a NPO supporting the homeless in collaboration with a public health center: Sadako KANAZAWA (Volunteer, NPO Medical Care Team of Shinjuku Renraku-Kai). It has been 20 years since the issue of homelessness emerged in Japanese society. The people with a history of both tuberculosis and experience of homelessness tend to show a poor prognosis. Our team has played an active role, working with Shinjuku Public Health Center for conducting a screening for tuberculosis every year. It seems that the screening service itself does not make a fundamental solution for homeless people with tuberculosis. Developing a more basic system of 'from street to apartment' is more essential. We believe that understanding the importance of the system is most essential to the people who are involved in health and medical care. 4. What we have learned from DOTS--Toward care by cuddling the patient's mind: Kazuyo ARIMA (PHN, Osaka City Public Health Center). Osaka City has achieved the goals of DOTS set up by the City's TB Control Guidelines since 2001 such as 80% DOTS implementation rate, halving the defaulter rate and incidence rate. It was shown by analysis that the treatment success depends on 'patient's awareness of the disease', 'appropriate DOTS method for each patient', 'existence of side effects', or 'the relationship between treatment supporters'. Through working for the patients whose treatment management was difficult, we have learned that our attitude towards the patients is a most important first step to build a good relationship and mutual trust with the patients, and DOT is an important tool. For treatment supporters,'the patient-centered care', 'care by staying close to the patients' or 'cuddling the patient' s mind' is most necessary to lead the patients to cure. 5. Patient's view: Through DOTS, my life has been renewed: Kuniyoshi MAEDA (Himawari no kai; Ex-homeless TB patients self-help group). It is an unforgettable memory that I was hospitalized due to TB back in 2009. I was seriously ill with also diabetes mellitus. Because I had lost everything due to my friend's cheating, I could not trust anyone before the TB treatment. But I learned how to think of others through the daily communication with doctors, nurses, other staff at the hospital, and Public Health Center. They encouraged me every day and I came to desire to answer to their expectations. Public health nurses taught me that building the reliable relationship is so essential for humans, and I may not have realized this importance if I had not been treated for TB, or treated outside Shinjuku. I would rather say that I was lucky to have got TB, as I have become able to trust other people through DOTS TB care. DOTS is not only for medication, but also general health care and counseling. I hope that as many as poor people, especially homeless can have a similar experience by knowing more about TB and using a health service. I would like to cooperate with TB services if I can be useful. health: Toshio TAKATORIGE (Graduate School of Safety Science, Kansai University). Tuberculosis was ever the biggest health problem in Japan. Ministry of Health and Welfare and Public Health Centers were founded to push forward tuberculosis control. Local governments, companies and people had to follow the national tuberculosis control program uniformly without exception. Currently a new stream of tuberculosis control has been started by DOTS strategy. The aim of DOTS has made all patients take medicine regardless of their social conditions until cure. Every patient is snuggled up and supported whether he is homeless, criminal or a foreigner. The patients also participate in the program actively. The DOTS may be a new public health movement. The strong public health infrastructure is necessary to maintain tuberculosis control towards the low incidence situation. The role of the local government should be more important. This symposium has also shown that the tuberculosis services must be patients-centered and supported by the people, addressing a new horizon of public health in Japan through tuberculosis control.     

Comparison of caregiver strain in Parkinson's disease between Yamagata,Japan, and Maryland,The United States

BackgroundJapan and the United States (US) have different cultures of caregiving including differences in family structure and social programs that may influence caregiver strain. Differences in caregiver strain between regions in Japan and in the US have not been investigated in patient–spouse dyads in PD.ObjectivesTo compare caregiver strain in spouses of PD patients between Yamagata, Japan and Maryland, US. Correlations between caregiver strain and patient/spousal variables are also examined.MethodsIn Yamagata and Maryland, spouses of patients with PD completed questionnaires assessing caregiver strain. Patients and spouses completed scales assessing mental health, and medical co-morbidity. PD severity and disability were assessed with the Unified Parkinson's Disease Rating Scale and the Schwab and England Activities of Daily Living Scale. Results in the two regions were compared with Chi-square and Student's t-tests. Relationships between caregiver strain and patient/spousal variables were analyzed with univariate correlations and multivariate regression.Results178 Spouse–patient pairs were assessed. The level of caregiver strain in PD did not differ between Yamagata, Japan and Maryland, US despite differences in demographics and social support programs in the two regions. Yamagata spouses reported physical, time and financial constraints, while Maryland spouses reported more emotional distress. In both regions, spousal depression was a significant contributor to caregiver strain.ConclusionDifferent approaches to reduce caregiver strain will likely be necessary in Yamagata and Maryland since the contributing factors to caregiver strain are influenced by differences in culture and social supports in each country.
