Background

To investigate the potential mechanisms of hypothermic machine perfusion (HMP)'s beneficial effects on kidney graft over static cold storage (SCS) in vitro.

Methods

Ten kidneys of 5 Bama miniature male pigs were paired into 2 groups: SCS group and HMP group. Preservation solutions were taken at 0, 1, 3, and 6 hours for the measurement of K+, Na+, Cl?, blood urea nitrogen (BUN), creatinine (Cr), and lactate dehydrogenase (LDH) using the standard laboratory methods. Renal cortex were harvested at 6 hours for the following measurement: lactic acid (LD), adenosine triphosphate (ATP), malondialdehyde (MDA), neutrophil accumulation (MPO), interleukin-10 (IL-10), and transforming growth factor-β (TGF-β). Ischemia-induced apoptosis and the protein expression levels of total Akt, phospho-Akt, total Erk, and phospho-Erk were analyzed by Western blotting.

Results

Almost all of the tested metabolites in preservation solutions were reduced with time in the HMP group. Levels of Na+, Cl?, BUN, Cr, K+, and LDH were lower in the HMP group compared with the SCS group, with differences in the first 4 reaching statistical significance. HMP alleviated ATP degradation and LD accumulation, diminished the MDA (P < .05) and MPO (P = .227) levels, and greatly raised IL-10 and TGF-β (P < .05) expression. A marked decrease of proapoptotic and a large increase of antiapoptotic markers (P < .05) along with greatly raised Akt (P < .05) and Erk (P < .01) phosphorylation was observed in the kidney of the HMP group compared with the SCS group.

Conclusion

HMP's kidney graft protection involves inhibition of accumulation of toxic metabolites, oxidative damage, and apoptosis along with upregulation of the Akt and Erk signaling pathway.  相似文献

ObjectivesTo determine whether microbial contamination of preservation solution (PS) in kidney transplantation is associated with donor-derived infections (DDIs).MethodsWe retrospectively analysed data from 1077 deceased kidney transplant recipients of 560 donors. In all, 1002 PS samples were collected for microbiological assessment to establish the incidence and distribution of contamination. Comparisons between patients with contaminated PS and those with sterile PS were performed to assess the impact of microbial contaminations in perfusate on probable donor-derived infections (p-DDIs), and potential risk factors for p-DDIs were examined.ResultsThe contamination rate of PS was 77.8% (402/517). Bacterial species accounted for 85.6% (887/1036) of the total 1036 isolated microorganisms and 26.5% (275/1002) of the recipients' PS were contaminated by ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp.). Enterococcus predominated the microbiological pattern. The incidence of infection was significantly higher in patients with microbial contamination than in patients with sterile PS (13.8% (107/776) versus 7.1% (16/226), p 0.006). The prevalence of p-DDIs was significantly higher in patients with ESKAPE contamination than in patients with other bacterial contamination in PS (7.2% (18/251) versus 1.0% (4/405), p 0.000). Univariate analysis indicated that ESKAPE contamination increased the risk of p-DDIs (p 0.001, OR 3.610, 95% CI 1.678–7.764). Multivariate analysis determined ESKAPE contamination as the only independent risk factor associated with p-DDIs (OR 3.418, 95% CI 1.580–7.393).ConclusionsThe high rate of microbial contaminations in PS is unusual and probably due to poor surgical procedures. Patients whose PS are contaminated by ESKAPE pathogens could have a significantly increased risk of p-DDIs at early post-transplantation.  相似文献

Background

Problems with recruitment and retention of village doctors have led to shortages in many parts of rural China. The situation has been deteriorating since 2009, when health reforms led to an increase in patient flow to township facilities, reducing village clinic attendance and doctors' income. We aimed to assess an intervention to reverse the decline in village doctor numbers in Jiangshan County, Zhejiang province.

Methods

This community-based prospective, non-randomised controlled trial was done across Jiangshan County, Zhejiang province, between January, 2012, and December, 2014. Our intervention group consisted of village clinics in Jiangshan County who voluntarily agreed to join the intervention group during the course of the study, with the remainder serving as controls. Clinics joined the intervention in a stepwise fashion: 17 in February, 2012, 17 in December, 2012, five in June, 2013, 47 in October, 2013, ten in January 2014, and eight in November, 2014. 104 village clinics (including five newly built clinics) had joined the intervention by the end of 2014. The remaining 83 village clinics served as controls. The intervention consisted of four components: (1) shift of the village clinic from private to collective ownership; (2) payments by local government to village doctors of ¥800 RMB per month, plus ¥4 RMB per patient visit; (3) introduction of a ¥5 RMB consultation fee, covered by health insurance; and (4) introduction of the zero-profit essential drug list (as in township hospitals) to discourage overprescribing and encourage patient attendance. Clinic records and doctors' views regarding job satisfaction and trust by patients, assessed by face-to-face interview, were compared at baseline and 36 months after initiation of the intervention. We obtained ethics approval from Zhejiang University, and participants gave oral informed consent.

Findings

Our sample consisted of 104 village doctors working at 104 clinics who received the intervention and 83 doctors at 83 clinics who did not (controls). In the 64 intervention clinics for which we had data for January to December, 2014 (the final year of assessment), patient visits increased from an annual mean of 2494 (SD 1214) per clinic in the year preceding baseline to 4316 (1223) in the final year of assessment (mean difference vs 40 controls, 2163; p<0·0001). Doctors' mean income increased from ¥44?900 RMB (SD ¥13?700) at baseline to ¥63?500 RMB (¥16?000) in the final year of assessment and the mean cost per visit fell from ¥50 RMB (SD 14) to ¥32 RMB (7). In the 64 intervention clinics analysed, the proportion of patients who were prescribed antibiotics or intravenous injections out of all attending patients, per patient visit, reduced from 69% to 44% (difference vs 40 controls 30·2%; p<0·0001), and 71% to 49% (difference vs controls 16·5%; p<0·0001), respectively. Between baseline and 36 months, 28 clinics opened in villages previously without a doctor. Of 64 doctors randomly selected for interview in intervention village clinics, 53 [83%] were very satisfied with the intervention, 49 (77%) were very satisfied with their income, 47 (73%) thought patient care had improved, and 55 (86%) thought that the doctor–patient relationship had improved. All the control clinics in Jiangshan have since joined the intervention.

Interpretation

In areas of rural China where local government can provide the necessary resources, the model we describe can address the shortfalls in health services at the village level.

Background

In China, the reported incidence of workplace violence in hospitals has been increasing. Most research has focused on secondary and tertiary care facilities. We aimed to determine the incidence of workplace violence and its aftermath in county and township hospitals and community health centres in Zhejiang Province.

Methods

A cross-sectional survey using stratified cluster sampling was carried out at 18 hospitals (eight county hospitals and ten township hospitals or community health centres) in Zhejiang Province from July 27, 2016 to Jan 20, 2017. Questionnaires were distributed to all health workers (including physicians, nurses, medical technicians, and administrative staff) present on the day of the survey. Ethical approval was obtained from Zhejiang University School of Public Health.

Findings

2018 out of 2303 participants completed questionnaires from 596 men and 1417 women. In the past year, 140 (7%) respondents had experienced physical attacks and 384 (19%) physical threats. Men experienced around twice as many physical attacks (59 [10%] vs 80 [6%] of women; p=0·001), and significantly more threats than females (132 [22%] vs 252 [18%]; p=0·025). Doctors were most likely to be victims of physical attacks, and the commonest location was the emergency department. Most respondents did not report the physical attack (117 [85%] respondents), mainly because they regarded it as pointless (70 [52%] respondents) or didn't know who to report to (32 [24%] respondents). Of all those attacked or threatened, 312 (61%) wanted to quit direct patient care. In terms of impact, 413 [80%] victims said they had repeated, disturbing memories of the attack, 498 [97%] said they had become highly vigilant, and 386 [75%] were fearful dealing with difficult cases. Only four [3%] were satisfied with the way the incident was handled.

Interpretation

Workplace violence is common at lower-level health facilities. The lack of a formal response to workplace violence implies an institutional tolerance which is of great concern. Guidelines for management of workplace violence need to be instituted in primary care facilities.

Purpose

Video-assisted lateral neck dissection (VALND) for papillary thyroid carcinoma (PTC) with lateral neck lymph node metastases (LNM) has been described previously, however, the advantages and drawbacks of VALND have not been demonstrated in previous studies. The aim of this study was to compare the surgical outcomes of video-assisted and open lateral neck dissection for PTC with lateral neck LNM.

Materials and methods

Between May 2013 and November 2014, 92 consecutive patients with PTC and lateral neck lymph node metastases underwent total thyroidectomy with central compartment neck dissection and unilateral lateral neck dissection. These included 54 individuals who underwent video-assisted surgery, and 38 in whom an open approach was used. The two groups were retrospectively compared with respect to their clinicopathological characteristics, surgical outcomes and oncological completeness.

Results

The mean follow-up period was 18.6 months. The mean tumor size, tumor stage, mean numbers of retrieved lymph nodes, mean postoperative serum thyroglobulin levels, complication rates, and mean postoperative hospital stay were similar between the two groups. The mean operation time was longer (p = 0.0001) and mean age was lower (p = 0.0354) in the video-assisted group. The cosmetic results, evaluated by numerical scale and verbal response scale, were in favor of the video-assisted group (p = 0.0003 and p < 0.0001, respectively).

Conclusions

The safety and oncological completeness of VALND was similar to that of open procedures, but the VALND resulted in improved cosmetic results. VALND is an effective treatment for the selected cases of PTC with lateral neck LNM.  相似文献
