ObjectiveTo investigate the effects of nasal continuous positive airway pressure (nCPAP) and intubation in very low birth weight preterm infants. Methods One hundred and twenty-three very low birth weight preterm infants with respiratory distress within 60 minutes after birth were randomly assigned to nCPAP (n=63) or intubation group (n=60).Outcomes at 7,28 days and 36 corrected gestational weeks were assessed with x2 or t-test. ResultsThere were no significant difference in fatality rate and incidence of bronchopulmonary dysplasia between nCPAP group and intubation group [7.9% (5/63) vs 6.6%(4/60),4.8%(3/63) vs 3.3%(2/60),x2 =0.07and 0.16,P>0.05].In nCPAP group,the use of pulmonary sulfactant was 27.0% (17/63),lower than that (83.3 %,50/60) in intubation group (x2 =39.34,OR=0.3,90 % CI:0.2-0.6,P<0.05) ;The nCPAP group had fewer ventilation support in 28 days [17.5% (11/63) vs 25.0% (15/60),OR=0.7,90% CI:0.4-1.4] and 36 weeks [6.3% (4/63) vs 8.3% (5/60),OR=0.8,90% CI:0.2-2.4] than those in intubation group but without statistical difference (x2=1.05 and 0.01,P>0.05,respectively).The incidence of air leak in nCPAP group were lower than intubation group [11.1% (7/63) vs 33.3% (20/60),x2 =8.86,OR=0.3,90%00 CI:0.2-0.7,P<0.05].There was no significant difference for other complications between two groups. ConclusionsIn very low birth weight preterm infants,early nCPAP dose not significantly reduce the fatality rate and the incidence of bronchopulmonary dysplasia as compared with intubation ventilation,but shorten the time of ventilation and lower the incidence of air leak.

Objective To evaluate the histologic changes in the dermis and the changes of the rate of type Ⅲ and type Ⅰ collagen by the radiofrequency device. Methods The effects of radiofrequency current on the dermis were observed. Ten rabbits were treated by radiofrequency, and the histologic change in the dermis were observed by H-E staining and Sirius red staining. Results After RF treatment, the fibers in the dermis appeared more compact and the quantity of the type Ⅲ (red) and type Ⅰ (green) collagen were both increased. The fibers in the dermis appeared more compact and the rate of type Ⅲ and type Ⅰ collagen was increased. It was also found that a significant proliferation of dermal collagen was observed in 8 days after treatment. As time went by, the proliferation of dermal collagen was more pronounced, and the rate of type Ⅲ was increased. Conclusion The radiofrequency current can increase the quantity of collagen in the dermis and increase the rate of type Ⅲ and type Ⅰ collagen, which may be one of the key mechanisms of facial rejuvenation by RF.

INTRODUCTIONHand infections in patients with end-stage renal failure (ESRF) are more diffi cult to treat and have had the worse outcomes. This paper examines the epidemiology, bacteriology and outcomes of surgically managed upper limb infections in these vulnerable patients.
MATERIALS AND METHODSAll patients from a single centre with surgically-managed upper limb infections between 2001 and 2007 were reviewed. We collected epidemiological data on demographics, type and site of infection, bacteriology, surgical treatment, complications and mortality.
RESULTSForty-seven out of 803 (6%) patients with surgically managed upper limb infections in the study period had ESRF. The average age was 59 years. ESRF was secondary to diabetes in 88% of cases. Patients presented on average 7 days after onset of symptoms. Abscesses (34%), wet gangrene (26%) and osteomyelitis (11%) were the commonest infections. Methicillin-resistant Staphylococcus aureus (MRSA) was the commonest pathogen (29%), occurring either in isolation or with other organisms. Eighteen percent of single organisms cultured were gram-negative. Multiple organisms occurred in 29%. A median of 2 operations were required. Thirty-six percent of all cases required amputation. Twenty-fi ve percent of patients had a life-threatening event (myocardial infarction or septic shock) during treatment.
CONCLUSIONSESRF patients present late with severe upper limb infections. Nosocomial infections are common. Initial empirical antibiotic treatment should cover MRSA and gram-negative bacteria. Immediate referral to a hand surgery unit is recommended. Multi-disciplinary management of the patient with input from physicians and anaesthetists or intensivists in the perioperative period is necessary to optimise the patient for surgery and to manage active medical comorbidities and complications after surgery.

The 1H-NMR fingerprints of three different species tibetan medicine sea buckthorn were established by 1H-HMR metabolomics to find out different motablism which could provide a new method for the quality evaluation of sea buckthorn. The obtained free induction decay (FID) signal will be imported into MestReNova software and into divide segments. The data will be normalized and processed by principal component analysis and.partial least squares discriminant analysis to perform pattern recognition. The results showed that 25 metabolites belonging to different chemical types were detected from sea buckthorn,including flavonoids, triterpenoids, amino acids, carbohydrates, fatty acids, etc. PCA and PLS-DA analysis showed three different varietiest of sea buckthorn that can be clearly separated by the content of L-quebrachitol, malic acid and some unidentified sugars, which can be used as the differences metabolites of three species of sea buckthorn. 1H-NMR-based metabonomies method had a holistic characteristic with sample preparation and handling. The results of this study can offer an important reference for the species identification and quality control of sea buckthorn.

INTRODUCTION:
Non-vitamin K oral anticoagulants (NOACs) were shown to have better outcomes than warfarin for non-valvular atrial fibrillation (NVAF). Given limited local real-world data, this study aims to evaluate the safety and efficacy of NOACs versus warfarin for NVAF in Singapore.
METHODS:
This single-centre retrospective cohort study included 439 patients ≥ 21 years old that were newly prescribed with oral anticoagulants (OACs) for NVAF in 2015. Follow-ups for patients upon OAC initiation lasted either for 2 years or until the occurrence of bleeding or thromboembolism event or death (whichever was earlier). Primary endpoints included major bleeding and stroke, while secondary endpoints included overall bleeding and thromboembolic events. Time-to-events was evaluated via Kaplan-Meier survival analysis. Data on time in therapeutic range (TTR) and compliance were analysed.
RESULTS:
Patients were assigned to 4 groups: warfarin (157, 35.8%), rivaroxaban (154, 35.1%), apixaban (98, 22.3%) and dabigatran (30, 6.8%). With a mean age of 70.8 (±10.8) years old, the population were predominantly males (56.5%) and comprised Chinese (73.8%), Malays (18.7%) and others (7.5%). The rates of stroke per year were 0.7%, 1.7%, 2.2% and 0% for warfarin, rivaroxaban, apixaban and dabigatran, respectively (
CONCLUSION
NOACs were associated with similar stroke and major bleeding rates as warfarin for NVAF.

OBJECTIVETo investigate the clinical effect of atlantoaxial pedicle screw internal fixation for treatment of atlantoaxial dislocation.
METHODSSixteen patients with atlantoaxial dislocation were treated from Dec. 2005 to June 2007, included 10 males and 6 females, aged from 38 to 45 years old (means 40.5 years). Among them 12 patients combined with nerve injury, according to ASIA grade: there were 3 cases in grade B, 5 cases in grade C, 4 cases in grade D. All patients received preoperative CT, radiograph and skull traction. Intraoperative posterior approach general spine pedicle screw-rod orthopaedics fixation system used and iliac bone block were implanted in space of posterior atlantal arch and axial vertebral plate. The outcome and complications were observed in the near future.
RESULTSThere was no vascular or neural injury found. The patients were followed up for 12 to 24 months (means 18 months). All head pain, acid storm symptoms were improved after operation. According to the Odom's clinical efficacy evaluation standard, 12 cases were excellent, 4 were good. Eleven cases of 12 with nerve injury recovered significantly. By ASIA classification: 1 cases was in grade B, 2 cases were in grade C, 5 cases were in grade D, 4 cases were in grade E. No looseness or breakage of screw occurred. Bony fusion was achieved in all cases.
CONCLUSIONPosterior approach atlantoaxial pedicle screw internal fixation have the advantages of direct screw placement, short-segment fusion, intraoperative reduction, fixation reliable, high fusion rate, and it can restablish the upper cervical vertebrae stability and help to recover the spinal cord and nerve function.

INTRODUCTIONNecrotising fasciitis is a disease associated with high morbidity and mortality, and multi-focal necrotising fasciitis is uncommon. We present 2 cases of concurrent necrotising fasciitis of contralateral upper and lower limbs.
CLINICAL PICTUREBoth presented with pain, swelling, bruising or necrosis of the affected extremities. Traditional medical therapy was sought prior to their presentation.
TREATMENTAfter initial debridement, one patient subsequently underwent amputation of the contralateral forearm and leg. The other underwent a forearm amputation, but refused a below-knee amputation.
OUTCOMEThe first patient survived, while the second died.
CONCLUSIONTraditional medical therapy can cause bacterial inoculation, leading to necrotising fasciitis, and also leads to delay in appropriate treatment. Radical surgery is needed to optimise patient survival.

Journal of the Korean Association of Oral and Maxillofacial Surgeons 2021;47(1):25-33
Objectives:
Many conditions of the oral and maxillofacial region require hospitalization and in-patient care. The average length of stay (LOS) of these patients varies and is usually affected by multiple confounding variables. However, even with an increasing number of hospital admissions, published evidence on the factors that affect the LOS of oral and maxillofacial patients is lacking. Therefore, this study assessed the LOS of in-patients at the oral and maxillofacial surgery department of a government-funded, multi-specialty hospital in Malaysia, based on their reasons for admission and other factors.
Materials and Methods:
Our samples were collected retrospectively over a 5-year period and included patients with maxillofacial infections, posttrauma stabilization, facial bone fracture surgery, benign and malignant lesion surgery, dentoalveolar surgery, and other maxillofacial surgeries as reasons for admission. Factors potentially affecting LOS were also recorded, and their significance was determined using multiple logistic regression analyses. A P-value of less than 0.05 was considered to be statistically significant.
Results:
A total of 1,380 patients were included in this study. Most (84.5%) of our in-patients were of Malay ethnicity, and males outnumbered females in our sample by 502 subjects. The median LOS of our in-patients was 3 days. Sex, ethnicity, age, reason for admission, and American Society of Anesthesiology (ASA) classification were factors that significantly affected LOS.
Conclusion
The median LOS reported in this study was 3 days. LOS was significantly affected by sex, ethnicity, age, reason of admission and ASA classification.

INTRODUCTION:
The cost-effectiveness of screening asymptomatic non-alcoholic fatty liver disease (NAFLD) patients remains debatable, with current studies assuming lifelong benefits of NAFLD screening while neglecting cardiovascular outcomes. This study aims to assess the cost-effectiveness of NAFLD screening among type 2 diabetes mellitus (T2DM) patients, and to establish a price threshold for NAFLD treatment, when it becomes available.
METHOD:
A Markov model was constructed comparing 4 screening strategies (versus no screening) to identify NAFLD with advanced fibrosis among T2DM patients: fibrosis-4 (FIB-4), vibration-controlled transient elastography (VCTE), FIB-4 and VCTE (simultaneous), and FIB-4 and VCTE (sequential). Sensitivity analyses and price threshold analyses were performed to assess parameter uncertainties in the results.
RESULTS:
VCTE was the most cost-effective NAFLD screening strategy (USD24,727/quality-adjusted life year [QALY]), followed by FIB-4 (USD36,800/QALY), when compared to no screening. Probabilistic sensitivity analysis revealed a higher degree of certainty for VCTE as a cost-effective strategy compared to FIB-4 (90.7% versus 73.2%). The duration of expected screening benefit is the most influential variable based on incremental cost-effectiveness ratio tornado analysis. The minimum duration of screening benefit for NAFLD screening to be cost-effective was at least 2.6 years. The annual cost of NAFLD treatment should be less than USD751 for NAFLD screening to be cost-effective.
CONCLUSION
Both VCTE and FIB-4 are cost-effective NAFLD screening strategies among T2DM patients in Singapore. However, given the lack of access to VCTE at primacy care and potential budget constraints, FIB-4 can also be considered for NAFLD screening among T2DM patients in Singapore.
