Financial impact of nosocomial infections on surgical patients in an eastern Chinese hospital: a propensity score matching study. J Hosp Infect 2023; 139:67-73. [PMID: 37301232 DOI: 10.1016/j.jhin.2023.05.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 04/18/2023] [Accepted: 05/17/2023] [Indexed: 06/12/2023]
Abstract
This study, conducted at Zhejiang Taizhou Hospital, China, aimed to examine the financial impact of nosocomial infections on surgical patients. A retrospective case-control study using propensity score matching was conducted over a 9-month period from January to September 2022. The study included 729 surgical patients with nosocomial infections and 2187 matched controls without infections. Medical expenses, length of hospitalization and total economic burden were compared between the two groups. The rate of nosocomial infections in surgical cases was 2.66%. The median hospitalization cost for patients with nosocomial infections was US$8220, compared with US$3294 for controls. The overall additional medical expenditure attributable to nosocomial infections amounted to US$4908. Notable median differences were observed between cases with nosocomial infections and controls in terms of total hospitalization cost, nursing services, medication, treatment, materials, test fees and blood transfusion fees. In each age group, medical costs for patients with nosocomial infections were more than twice those of controls. Additionally, hospital stays for surgical patients with nosocomial infections were, on average, 13 days longer compared with controls. These findings highlight the importance of implementing effective infection control measures in hospitals to reduce the financial burden on patients and the healthcare system.

Abstract
Objective: To investigate whether CT coronary angiography (CTA) can safely and effectively reduce the number of invasive coronary angiography (ICA) in patients with non-ST-segment elevation myocardial infarction (NSTEMI) whose Grace score is low-or moderate-risk, and increase ICA positive rate. Methods: One hundred and two NSTEMI patients, including 61 males and 41 females, aged 38-80 (58±12) years, were prospectively included and treated in Henan Provincial People's Hospital from February 2017 to February 2018. By using random number method, the patients were divided into control group (51 cases) and experimental group (51 cases). Patients in the control group were arranged for elective ICA examination according to the risk stratification. If further intervention or surgical treatment was required, the ICA examination was positive; in the experimental group, the CTA examination was completed through the green channel first. If the CTA showed that the main coronary artery and its main branches were severe or extreme stenosis, further ICA examination was arranged; otherwise, a secondary prophylactic drug treatment was developed and the patients were then discharged and followed up for 1 year. ICA number, ICA positive rate, length of hospital stay, hospital cost, hospital anxiety and depression score (HADS), major cardiovascular events (MACE) within 1 year, and other serious adverse events related to examination or surgery were compared between the two groups. Results: A total of 37 patients in the experimental group underwent ICA, and the positive rate of ICA was 94.59% (35/37), which was significantly higher than that of the control group [62.75% (32/51)] (P<0.05). The average length of hospital stay and the HADS score before ICA in the experimental group were significantly lower than those in the control group [(3.8±2.2) d vs (4.8±2.4) d; 8.8±4.5 vs 11.4±6.8] (all P<0.05). There was no significant difference in the cumulative incidence of MACE (3 cases vs 5 cases, P=0.423) and other serious adverse events (8 cases vs 10 cases, P=0.548) within 1 year between the two groups. Conclusion: CTA significantly reduces the number of ICA and the average length of hospital stay, and increases the positive rate of ICA in NSTEMI patients whose Grace score is low-or moderate-risk. There is no increase in cardiovascular risks within 1 year.

LncRNA HULC promotes non-small cell lung cancer cell proliferation and inhibits the apoptosis by up-regulating sphingosine kinase 1 (SPHK1) and its downstream PI3K/Akt pathway. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2019; 22:8722-8730. [PMID: 30575912 DOI: 10.26355/eurrev_201812_16637] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 11/12/2022]
Abstract
OBJECTIVE LncRNA HULC has been proved to have important functions in the pathogenesis of several types of cancers. While its involvement in non-small cell lung cancer (NSCLC), which is one of the most common malignancies, still hasn't been reported to date. Therefore, we aimed to investigate the role of HULC in NSCLC and to explore the possible mechanisms. PATIENTS AND METHODS Tumor tissues and adjacent healthy tissues were collected from NSCLC patients, and blood samples were collected from both NSCLC patients and healthy controls. Expression of HULU in those tissues was detected by qRT-PCR. All patients were followed up for 5 years. Diagnostic and prognostic values of serum HULU for NSCLC were investigated by ROC curve analysis and survival curve analysis, respectively. HULC overexpression NSCLC cell lines were established and its effects on cell proliferation as well as apoptosis were investigated by CCK-8 assay and MTT assay, respectively. Effects of HULC overexpression on sphingosine kinase 1 (SPHK1) and its downstream PI3K/Akt pathway were investigated by Western blot. RESULTS HULC expression level was increased in tumor tissues compared with adjacent healthy tissues in most patients. Serum level of HULC was higher in cancer patients than that in healthy control. Serum level of HULC was increased with the increased stage of primary tumor (T stage). Serum HULC can be used to accurately predict NSCLC and its prognosis. HULC overexpression promoted tumor cell proliferation, but inhibited cell apoptosis. HULC overexpression also increased expression level of SPHK1 and phosphorylation level of Akt in NSCLC cell, but showed on significant effects on Akt expression. Treatment with SPHK1 inhibitor and Akt reduced the effects of HULC overexpression on proliferation and apoptosis of NSCLC cells. But the treatment showed no significant effects on HULC expression. SPHK1 inhibitor treatment inhibited phosphorylation of Akt, while Akt inhibitor treatment showed no significant effects on SPHK1 expression. CONCLUSIONS LncRNA HULC overexpression can promote NSCLC cell proliferation and inhibit cell apoptosis by up-regulating sphingosine kinase 1 (SPHK1) and further induce the activation of its downstream PI3K/Akt pathway.

Abstract
Objective: To compare and analyze the differentially expressed plasma exosomic proteome between healthy control group (Control group) and viral myocarditis group (VMC group) to search for biomarkers that maybe used for early diagnosis of VMC. Methods: Fifty plasma samples of Control group and VMC group were collected respectively from Henan Provincial People's Hospital (from January 2016 to December 2017), and then 5 samples (1 ml) of each group were selected randomly, after exosomes extraction with ultra-centrifugation, difference gel electrophoresis (DIGE) was used to isolate the total proteins, and then the protein spots with more than 2-fold changes between VMC and Control group were picked up after the software analysis, afterward, the varied proteins were identified by MALDI-TOF/TOF mass spectrometry. Finally, the specifically related protein was selected to be verified by ELISA with the plasma exosomic samples of Control (n=40) and VMC (n=40). Results: A total of 10 varied protein spots were found including 8 up-regulated proteins and 2 down-regulated proteins between VMC and Control group. After MS analysis, the up-regulated proteins in VMC group contained KRT2, KRT5, KRT9, KRT77, KRT78, AZGP1, HP and RBP4, whereas the down-regulated ones were CD5L and C1QB. RBP4 was selected to validate by ELISA analysis, and the corresponding results showed that RBP4 was increased specifically in plasma exosomes of VMC group (P<0.05) after comparing with Control group, which was consistent with DIGE. Conclusion: Ten proteins related to VMC are detected in total, and RBP4 might serve as a potential specific biomarker for early screening and diagnosis of VMC.

Abstract
Objective: To analyze the effect of insufficient intake of vitamin D (VD) on sperm quality and male fertility and to discuss the mechanism of the effect. Methods: VD deficiency mice were fed with VD-deficient diet and light-sheltered. The sperm motility, morphology, ultrastructure, testicular pathology, sex hormones and fertility of normal and VD-deficient mice were analyzed to investigate the effects of VD deficiency on male reproduction. Results: Compared with the normal group, the mice with VD deficiency had lower sperm concentration[(128±53) ×10(6)/ml vs( 58±15) ×10(6)/ml, P<0.05], less sperm in the epididymis, slightly less mature spermatozoa.The serum testosterone[(328±65 )nmol/L vs(255±58 )nmol/L]and estradiol levels[(60±115) pmol/L vs(384±104) pmol/L]were significantly lower (P<0.05), and the FSH[(296±177)ng/L vs(219±105 )ng/L]and LH[(393±129) ng/L vs(364±108) ng/L]levels were significantly higher (P<0.05). The other tests did not show any significant difference (P>0.05). Conclusion: The impact of insufficient intake of VD on sperm quality is not prominent, the specific impact of VD on male reproductive needs to be further studied.

Abstract
Objective: To analyze the sperm morphological characteristics of multiple morphological abnormalities of the sperm flagella (MMAF), and to analyze their common features and subtypes. Methods: Twenty-eight patients with abnormal morphology of flagella were analyzed by semen analysis. The morphological characteristics were analyzed by scanning electron microscopy and transmission electron microscopy. Histological observation of one case of testicular tissue was performed. Results: Of the 28 patients, only 13 patients (46.4%) had motile spermatozoa, 12 of which had a sperm motility rate of <10% and a sperm survival rate of 9.0%-80.0%. Under light and scanning electron microscope, sperm with absent, short, coiled, bent and irregular width flagella or their combinations were observed. Transmission electron microscopy showed structural abnormalities of sperm fibrous sheath, mitochondrial sheath. Loss rate of central microtubule was 41.4%-84.6%. The semen of the 2 patients with the absence or presence of the kinetic protein arm and both the inner and lateral motilin arms missing had no motile spermatozoa. There was no statistically significant difference in the proportion of flagellar malformations between the two groups of patients (without motile sperm vs with motile spermatozoa). Conclusion: MMAF is a kind of sperm flagella specific abnormalities. Initially diagnosis can be carried out using light microscopy. Clear diagnosis could be conduct using transmission electron microscopy, and the central microtubule loss of the sperm could be seen as the main feature of the flagella abnormalities. Through the morphological analysis and research, MMAF could be precisely classified, which provide a strong basis for the diagnosis.

Abstract
OBJECTIVE To analyze the influence of trabecular microstructure modeling on the biomechanical distribution of implant-bone interface with a three-dimensional finite element mandible model of trabecular structure. METHODS Dental implants were embeded in the mandibles of a beagle dog. After three months of the implant installation, the mandibles with dental implants were harvested and scaned by micro-CT and cone-beam CT. Two three-dimensional finite element mandible models, trabecular microstructure(precise model) and macrostructure(simplified model), were built. The values of stress and strain of implant-bone interface were calculated using the software of Ansys 14.0. RESULTS Compared with the simplified model, the precise models' average values of the implant bone interface stress increased obviously and its maximum values did not change greatly. The maximum values of quivalent stress of the precise models were 80% and 110% of the simplified model and the average values were 170% and 290% of simplified model. The maximum and average values of equivalent strain of precise models were obviously decreased, and the maximum values of the equivalent effect strain were 17% and 26% of simplified model and the average ones were 21% and 16% of simplified model respectively. Stress and strain concentrations at implant-bone interface were obvious in the simplified model. However, the distributions of stress and strain were uniform in the precise model. CONCLUSIONS The precise model has significant effect on the distribution of stress and strain at implant-bone interface.

Abstract
AIMS/HYPOTHESIS The aim of this study was to determine the potential role of sphingosine kinase 1 (SPHK1), a key sphingolipid metabolic enzyme, in glucose metabolism and homeostasis. METHODS SMMC-7721 hepatoma cells and C2C12 myotube cells were used to explore the role of SPHK1 in glucose uptake in vitro. KK/Ay type 2 diabetic mice, which were transfected with adenovirus harbouring the human SPHK1 gene by i.v. injection, were used to investigate the glucose-lowering effects of SPHK1 in vivo. RESULTS The basal glucose uptake and the insulin-stimulated glucose uptake in both 7721 cells and C2C12 cells were markedly enhanced when SPHK1 was overexpressed by adenovirus-mediated gene transfer, whereas they were substantially reduced when the expression of SPHK1 was inhibited or the activity of SPHK1 was blocked. Insulin could activate SPHK1 of both cell lines in a dose-dependent manner. SPHK1 gene delivery significantly reduced the blood glucose level of KK/Ay diabetic mice, but had no effect on that of normal animals. It also attenuated elevated levels of plasma insulin, NEFA, triacylglycerol, cholesterol and LDL, significantly ameliorated hyperglycaemia-induced injury of liver, heart and kidney, and enhanced phosphorylation of insulin-signalling kinases such as Akt and glycogen synthase kinase 3beta in livers of the diabetic animals. CONCLUSIONS/INTERPRETATION SPHK1 is involved in insulin signalling and plays an important role in the regulation of glucose and fat metabolism; adenovirus-mediated SPHK1 gene transfer might provide a novel strategy in the treatment of type 2 diabetes mellitus.

Abstract
A 25-year-old female was admitted for evaluation of hypertension and hypokalemia. Plasma renin activity was suppressed and plasma aldosterone level was higher than normal. The CT scan of adrenal gland revealed a 2.5cm in size low density tumor mass over right adrenal area, and NP-59 adrenal scan showed early and persistent uptake of radioactivity in the right adrenal gland. Interestingly, the plasma aldosterone level was elevated, decreased and unchanged to postural change on three different occasions. After right adrenalectomy, the plasma aldosterone level decreased to 4.77ng/dl, blood pressure, serum potassium, and plasma aldosterone returned to normal response to postural change. Histologically, it was compatible with the picture of cortical adenoma. However, the tumor cell may not have reached autonomous function yet, since different responses of plasma aldosterone to postural change were observed clinically.

Abstract
Parallel measurements of circulating thyroglobulin (Tg), microsomal [TPO(mic)] and TSH-receptor antibodies [TSH-R(rr)] were performed in 30 cases of Graves' hyperthyroid patients who received antithyroid drug (ATD) therapy for 2.8 +/- 1.7 years (range: 0.5-5.0 years). Before ATD therapy, positive Tg, TPO(mic) and TSH-R(rr) antibodies were found in 33.3%, 83.3% and 86.7% of our patients with Graves' disease, respectively. The titers of Tg and TPO(mic) antibodies remained unchanged in most patients after ATD treatment. However, the TSH-R(rr) antibody titers decreased in 46.7%, elevated in 26.7% and unchanged in 26.7% after ATD therapy. Six cases got long-term remission. Measurements of Tg and TPO antibodies have no value in forecasting the outcome of the disease. The change of circulating TSH-R(rr) antibody from positive to negative is more predictive of remission after ATD therapy than the decrease of thyrotropin-binding inhibiting immunoglobulin index only. However, the former change indicating a persistent remission is not certain.

Abstract
In treating DKA and HHNK, low dose insulin therapy has been confirmed to be efficient and with less complications than traditional high dose insulin therapy. In 1981, we have reported 157 cases of DKA and HHNK at VGH. Between January 1986 and December 1987, 98 cases of DKA and HHNK were encountered at VGH. 40 patients had 48 episodes of DKA their mean age were 56 years. Comparing with the previous report, we found that the main precipitating factors were infection (41.6% vs 38.8%), omission of insulin (27.1% vs 34.7%) and there were cases without any precipitating factors (18.7% vs 24.8%). 3 cases died (6.2% vs 7.3%) in three days. During treatment, hypoglycemia were found in 4 cases (8.3% vs 5.2%) and hypokalemia were noted in 30 cases (62.5% vs 42.3%). 47 patients had 50 episodes of HHNK, their mean age were 68.7 years. Comparing with the previous experience, the main precipitating factors were infection (44% vs 45.7%), omission of insulin (16% vs 20%) and cardiovascular disorder (12% vs 31.4%), there were some episodes without any precipitating factors (20% vs 8.6%). 10 cases died (20% vs 20%) in three days, hypoglycemia were noted in 2 cases (4% vs 3%) and hypokalemia in 20 cases (42% vs 27.3%). It seems, even with better knowledge, facilities and increased experience in the management of diabetic emergencies, no dramatic change in morbidity and mortality was noted over the past 7 years.
