Abstract
Rumen-protected choline (RPC) promotes benefits in milk production, immunity, and health in dairy cows by optimizing lipid metabolism during transition period management and early lactation. However, the RPC success in dairy cows depends on choline bioavailability, which is affected by the type of protection used in rumen-protected choline. Therefore, our objectives were to determine the effects of a novel RPC on dry matter intake (DMI), identify markers of metabolism and immunity, and evaluate lactation performance. Dry Holstein (n = 48) cows at 245 ± 3 d of gestation were blocked by parity and assigned to control or RPC treatment within each block. Cows enrolled in the RPC treatment received 15 g/d of CholiGEM (Kemin Industries, Cavriago RE, Italy) from 21 d prepartum and 30 g/d of CholiGEM from calving to 21 d postpartum. During the transition period, DMI was measured daily, and blood was sampled weekly for energy-related metabolites such as β-hydroxybutyrate (BHB), glucose, and nonesterified fatty acids (NEFA), as well as immune function markers such as haptoglobin (Hp) and lipopolysaccharide-binding protein (LPB). Vaginal discharge samples were collected at the calving and 7 d postpartum and stored in microcentrifuge tubes at -80°C until 16S rRNA sequencing. The main responses of body condition score, body weight, DMI, milk yield, milk components, and immune function markers were analyzed using the GLIMMIX procedure of SAS with the effects of treatment, time, parity, and relevant covariates added to the models. The relative abundance of microbiome α-diversity was evaluated by 3 indexes (Chao1, Shannon, and Simpson) and β-diversity by principal coordinate analysis and permutational multivariate ANOVA. We found no differences in DMI in the pre- and postpartum periods. Cows fed RPC increased the yields of energy- and 3.5% fat-corrected milk and fat yield in primiparous and multiparous cows, with an interaction between treatment and parity for these lactation variables. However, we found no differences in milk protein and lactose up to 150 DIM between treatments. Glucose, NEFA, and BHB had no differences between the treatments. However, RPC decreased BHB numerically (control = 1.07 ± 0.13 vs. RPC = 0.63 ± 0.13) in multiparous on the third week postpartum and tended to reduce the incidence of subclinical ketosis (12.7% vs. 4.2%). No effects for Hp and LPB were found in cows fed RPC. Chao1, Shannon, and Simpson indexes were lower at calving in the RPC treatment than in the Control. However, no differences were found 7 d later for Chao1, Shannon, and Simpson indexes. The vaginal discharge microbiome was altered in cows fed RPC at 7 d postpartum. Fusobacterium, a common pathogen associated with metritis, was reduced in cows fed RPC. Rumen-protected choline enhanced lactation performance and health and altered the vaginal discharge microbiome which is a potential proxy for uterine healthy in dairy cows. The current study's findings corroborate that RPC is a tool to support adaptation to lactation and shed light on opportunities for further research in reproductive health.

Abstract
The initial ovulatory response during synchronization programs is often low in dairy heifers, largely due to follicular dynamics and hormonal dynamics. Specifically, the progesterone concentration (P4) at the time of the first GnRH treatment in a breeding program can influence the LH response, often resulting in a suboptimal ovulatory response. The objective of this study was to determine the effect of the highest label dose 200 μg (100 μg vs. 200 μg) of GnRH (50 μg gonadorelin hydrochloride per mL; Factrel®; Zoetis Inc. Madison, NJ) at the first GnRH of a 6-d CoSynch plus P4 device program on ovulatory response and pregnancy per AI (P/AI) in first service in Holstein heifers. A total of 1308 Holstein heifers were randomly allocated at the beginning of a 6-d CIDR-Synch program, Day 0, to receive either i.m. treatment of 100 μg (2CC, n = 655) or 200 μg (4CC, n = 653) of GnRH. Also, at Day 0, heifers received an intravaginal insert with 1.38 g of P4 (Eazi-Breed CIDR® Cattle Insert; Zoetis Inc., Madison, NJ). On Day 6, the insert was removed, and i.m. treatment of 25 mg of PGF2α (12.5 mg dinoprost tromethamine/mL; Lutalyse® HighCon Injection Zoetis) was administered. On Day 7, a second i.m. treatment of 25 mg of PGF2α was given, followed on Day 9 by concurrent i.m. treatment of 100 μg of GnRH and timed AI (TAI). A subset of 396 heifers had their ovaries scanned to evaluate ovulatory response, and blood samples were collected to measure the serum concentration of P4 at Day 0 and Day 6 of the study. The P4 concentrations at Day 0 were categorized as Low (≤3ng/mL) or High (>3ng/mL). The ovulatory response was greater for heifers receiving 4CC than 2CC at Day 0 (54.7% vs. 42.8%). The ovulatory response was greater for Low P4 than High P4 at Day 0 (54.3% vs. 37.8%). However, there was not an interaction between treatment and P4 concentrations (Low P4 2CC = 48.6% vs. High P4 2CC = 30.0%; Low P4 4CC = 60.0% vs. High P4 4CC = 45.5%). The ROC curve analysis indicates that P4 concentrations at Day 0 treatment could predict the ovulatory response, although the area under the curve was only 0.6. As expected, heifers that ovulated had increased P/AI (No = 55.6% vs. Yes = 67.7%); however, there was no effect of treatment on P/AI (2CC = 63.3% vs. 4CC = 59.6%), nor interactions between treatment and ovulation and treatment and P4 (HIGH vs LOW) for pregnancy outcomes. In summary, P4 concentration and increasing the dose of GnRH at Day 0 positively impacted ovulatory response in Holstein heifers. However, there was no interaction between treatment and P4 on ovulation and no subsequent impact of GnRH dose on P/AI.

Abstract
IMPORTANCE Wearing a face mask in school can reduce SARS-CoV-2 transmission but it may also lead to increased hand-to-face contact, which in turn could increase infection risk through self-inoculation. OBJECTIVE To evaluate the effect of wearing a face mask on hand-to-face contact by children while at school. DESIGN, SETTING, AND PARTICIPANTS This prospective randomized clinical trial randomized students from junior kindergarten to grade 12 at 2 schools in Toronto, Ontario, Canada, during August 2020 in a 1:1 ratio to either a mask or control class during a 2-day school simulation. Classes were video recorded from 4 angles to accurately capture outcomes. INTERVENTIONS Participants in the mask arm were instructed to bring their own mask and wear it at all times. Students assigned to control classes were not required to mask at any time (grade 4 and lower) or in the classroom where physical distancing could be maintained (grade 5 and up). MAIN OUTCOMES AND MEASURES The primary outcome was the number of hand-to-face contacts per student per hour on day 2 of the simulation. Secondary outcomes included hand-to-mucosa contacts and hand-to-nonmucosa contacts. A mixed Poisson regression model was used to derive rate ratios (RRs), adjusted for age and sex with a random intercept for class with bootstrapped 95% CIs. RESULTS A total of 174 students underwent randomization and 171 students (mask group, 50.6% male; control group, 52.4% male) attended school on day 2. The rate of hand-to-face contacts did not differ significantly between the mask and the control groups (88.2 vs 88.7 events per student per hour; RR, 1.00; 95% CI, 0.78-1.28; P = >.99). When compared with the control group, the rate of hand-to-mucosa contacts was significantly lower in the mask group (RR, 0.12; 95% CI, 0.07-0.21), while the rate of hand-to-nonmucosa contacts was higher (RR, 1.40; 95% CI, 1.08-1.82). CONCLUSIONS AND RELEVANCE In this clinical trial of simulated school attendance, hand-to-face contacts did not differ among students required to wear face masks vs students not required to wear face masks; however, hand-to-mucosa contracts were lower in the face mask group. This suggests that mask wearing is unlikely to increase infection risk through self-inoculation. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04531254.

Abstract
Tramadol is a bitter atypical opioid analgesic drug and is prescribed to treat postoperative pain in children. However, in many countries there is no licensed paediatric tramadol formulation available. We have formulated a novel chewable chocolate-based drug delivery system for the administration of tramadol to children. This pilot, single-centre, open-label, randomised clinical study assessed the taste tolerability and comparative population pharmacokinetics of the novel tramadol chewable tablet against a compounded tramadol hydrochloride oral liquid, at a dose of 1 mg.kg-1 . A 5-point facial hedonic scale was used by the children, parents and nurses to assess tolerability. One hundred and forty-one children aged 3-16 years were given tramadol 30 min before general anaesthesia. Blood samples were taken following the induction of anaesthesia and for up to 5 h following tramadol administration. Tramadol and its active metabolite O-desmethyltramadol were analysed using reversed-phase high-performance liquid chromatography. A population pharmacokinetic model was built using non-linear mixed effects modelling. The relative bioavailability for the tablet was 1.25 times higher (95%CI 1.16-1.35) than for tramadol hydrochloride oral liquid, while the absorption rate constant for the tablet was significantly lower (1.97 h-1 vs. 3.34 h-1 , p < 0.001). Larger inter-individual variability in absorption rates were observed with the liquid tramadol. The tramadol chewable tablet was more acceptable in taste to children when assessed by the children, parents and nurses (all p < 0.001). We conclude that the novel tramadol chewable tablet has favourable acceptability and more reliable relative bioavailability in children compared with tramadol hydrochloride oral liquid.

Abstract
This study was performed to evaluate whether the use of drugs in the treatment of osteoporosis in women is associated with COVID-19 outcomes. The results showed that the risk of hospitalization, intensive care unit admission, and mortality was not altered in individuals taking anti-osteoporosis drugs, suggesting no safety issues during a COVID-19 infection. INTRODUCTION Whether patients with COVID-19 receiving anti-osteoporosis drugs have lower risk of worse outcomes has not been reported yet. The aim of this study was to evaluate the association of anti-osteoporosis drug use with COVID-19 outcomes in women. METHODS Data obtained from a nationwide, multicenter, retrospective cohort of patients diagnosed with COVID-19 from March 11th to May 30th, 2020 was retrieved from the Turkish Ministry of Health Database. Women 50 years or older with confirmed COVID-19 who were receiving anti-osteoporosis drugs were compared with a 1:1 propensity score-matched COVID-19 positive women who were not receiving these drugs. The primary outcomes were hospitalization, ICU (intensive care unit) admission, and mortality. RESULTS A total of 1997 women on anti-osteoporosis drugs and 1997 control patients were analyzed. In the treatment group, 1787 (89.5%) women were receiving bisphosphonates, 197 (9.9%) denosumab, and 17 (0.9%) teriparatide for the last 12 months. Hospitalization and mortality rates were similar between the treatment and control groups. ICU admission rate was lower in the treatment group (23.0% vs 27.0%, p = 0.013). However, multivariate analysis showed that anti-osteoporosis drug use was not an independent associate of any outcome. Hospitalization, ICU admission, and mortality rates were similar among bisphosphonate, denosumab, or teriparatide users. CONCLUSION Results of this nationwide study showed that preexisting use of anti-osteoporosis drugs in women did not alter the COVID-19-related risk of hospitalization, ICU admission, and mortality. These results do not suggest discontinuation of these drugs during a COVID-19 infection.

Abstract
Multimodal analgesia is employed in paediatric pain management to maximise analgesia and minimise side effects. Tramadol is dosed at 1-1.5 mg/kg to treat severe pain in children but the assay for tramadol in plasma samples for pharmacokinetic and toxicology studies does not often consider concurrently administered medications. In this study we developed and validated an HPLC-UV method to quantify tramadol and its main metabolite (O-desmethyltramadol) in human plasma in the presence of seven potentially interfering drugs. Sample preparation method was developed by combining liquid-liquid extraction and protein precipitation. Chromatographic separation was achieved on a BDS-Hypersil-C18 column (5 µm, 250 × 4.6 mm) using a double gradient method. The limit of quantification was 6.7 ng/ml for both tramadol and ODT. The precision and accuracy were in compliance with ICH guidelines. This method was successfully employed to analyse the blood samples of 137 paediatric participants in a tramadol pharmacokinetic trial.

Abstract
BACKGROUND Suicide and risk management protocols in mental health research aim to ensure patient safety, provide vital information on how to assess suicidal ideation, manage risk, and respond to unexpected and expected situations. However, there is a lack of literature that identifies specific components and strategies to include in suicide and risk management protocols (SRMPs) for mental health research. The goal of this scoping review was to review academic and grey literature to determine core components and associated strategies, which can be used to inform SRMPs in mental health research. METHODS AND ANALYSIS The methodological framework outlined by Arksey and O'Malley was used for this scoping review. The search strategy, conducted by a medical librarian, was multidisciplinary and included seven databases. Two reviewers independently assessed eligibility criteria in each document and used a standardized charting form to extract relevant data. The extracted data were then examined using qualitative content analysis. Specifically, summative content analysis was used to identify the core components and strategies used in SRMPs. The data synthesis process was iterative. RESULTS This review included 36 documents, specifically 22 peer-reviewed articles and 14 documents from the grey literature. Five core components of SRMPs emerged from the reviewed literature including: training; educational resources for research staff; educational resources for research participants; risk assessment and management strategies; and clinical and research oversight. Potentials strategies for risk mitigation within each of the core components are outlined. CONCLUSIONS The five core components and associated strategies for inclusion in SRMPs will assist mental health researchers in conducting research safely and rigorously. Findings can inform the development of SRMPs and how to tailor them across various research contexts.

Abstract
Establishing cell lines is a good model for experimental applications to study molecular mechanisms and cell-specific gene expression. Equids have a diffuse epitheliochorial placenta, where the invasive trophoblast is represented by the chorionic girdle (CG) and the noninvasive trophoblast by the allantochorion (AC). Embryonic CG cells are unique to horses and have a crucial role in equine chorionic gonadotropin (eCG) production and maintenance of pregnancy during the first trimester. This study had three objectives: (1) establishing a stable cell line from Day 30 CG cells and AC using lentivirus encoding hTERT; (2) characterisation of Day 30 CG cells and AC cell morphology and expression of eCG α (eCGA) and β (eCGB) subunits, major histocompatibility complex class II (MHCII), and Kisspeptin receptor (KISS1R) in CG and AC cells; (3) investigating eCG protein production invitro from Day 30 CG and AC cells. Three mares (n=3) were used to collect Day 30 conceptuses by non-surgical uterine lavage on Day 30 of pregnancy. All 3 conceptuses were dissected for CG and AC cells then cultured invitro to confluency in cell culture plates. Second-generation lentiviral particles were generated using a three-vector system including transfer vector pLV-hTERT-IRES-hygro, and human telomerase reverse transcriptase (hTERT) lentivirus was utilised to establish stable hygromycin-resistant equine embryonic cell lines. Reverse-transcription PCR (RT-PCR) was used to study gene expression in cells and radioimmunoassay was used to investigate protein presence in the media. We established a hygromycin-resistant Day 30 CG and AC cell lines that express eCGA, eCGB, and hTERT and confirmed using RT-PCR yielding the predicted bands. The cell lines were maintained for 16 passages (7±2 days/passage), 10 of which were cultured after the lentiviral infection steps. Also, we characterised CG cells as fast-growing, large, binucleated, and epithelioid, and AC cells as rapid-growing showing smaller, squamous, mononucleate, epithelioid, and elongated fibroblastic cells. The RT-PCR results showed eCGA and eCGB subunits are expressed by both Day 30 CG and AC cells, but MHCII and KISS1R genes were not expressed in either of cells. Moreover, radioimmunoassay results showed that Day 30 CG cells did produce eCG protein (35.42ngmL−1) invitro earlier than what previous literature has shown. However, Day 30 AC cells did not produce eCG protein (0.042ngmL−1) invitro, and both CG and AC cell lines stopped secreting eCG in the media after the lentiviral infection. To conclude, establishing stable and hygromycin-resistant cell lines from Day 30 equine CG and AC cells using lentivirus encoding pLV-hTERT-IRES-hygro is attainable. Also, equine chorionic gonadotropin eCG protein is produced invitro as early as Day 30 from CG cells.

Abstract
The aim of this study was to quantitatively evaluate the efficacy of induced hypotensive anesthesia in decreasing facial soft tissue perfusion during orthognathic surgery using laser-assisted indocyanine green fluorescence angiography. This retrospective study involved the evaluation of 16 patients who underwent orthognathic surgery. Data collection included facial tissue perfusion of the bilateral cheeks and chin at normotension and with pharmacologically induced hypotensive anesthesia. There were statistically significant differences in the facial tissue perfusion at normal and depressed levels of blood pressure (P<0.001). This study used an objective measure to demonstrate the long-standing belief that hypotensive anesthesia is efficacious in reducing tissue perfusion in the surgical field. The data suggest that pharmacologically depressing the level of mean arterial pressure by 18% may result in a 41-52% decrease in facial soft tissue perfusion. This study reports a novel method of quantitative analysis.

Abstract
OBJECTIVE Overexpression of tissue-nonspecific alkaline phosphatase (TNAP) in endothelium leads to arterial calcification in mice. The purpose of this study was to examine the effect of elevated endothelial TNAP on coronary atherosclerosis. In addition, we aimed to examine endogenous TNAP activity in human myocardium. APPROACH AND RESULTS A vascular pattern of TNAP activity was observed in human non-failing, ischemic, and idiopathic dilated hearts (5 per group); no differences were noted between groups in this study. Endothelial overexpression of TNAP was achieved in mice harboring a homozygous recessive mutation in the low density lipoprotein receptor (whc allele) utilizing a Tie2-cre recombinase (WHC-eTNAP mice). WHC-eTNAP developed significant coronary artery calcification at baseline compared WHC controls (4312 vs 0μm2 alizarin red area, p<0.001). Eight weeks after induction of atherosclerosis, lipid deposition in the coronary arteries of WHC-eTNAP was increased compared to WHC controls (121633 vs 9330μm2 oil red O area, p<0.05). Coronary lesions in WHC-eTNAP mice exhibited intimal thickening, calcifications, foam cells, and necrotic cores. This was accompanied by the reduction in body weight and left ventricular ejection fraction (19.5 vs. 23.6g, p<0.01; 35% vs. 47%, p<0.05). In a placebo-controlled experiment under atherogenic conditions, pharmacological inhibition of TNAP in WHC-eTNAP mice by a specific inhibitor SBI-425 (30mg*kg-1*d-1, for 5 weeks) reduced coronary calcium (78838 vs.144622μm2) and lipids (30754 vs. 77317μm2); improved body weight (22.4 vs.18.8g) and ejection fraction (59 vs. 47%). The effects of SBI-425 were significant in the direct comparisons with placebo but disappeared after TNAP-negative placebo-treated group was included in the models as healthy controls. CONCLUSIONS Endogenous TNAP activity is present in human cardiac tissues. TNAP overexpression in vascular endothelium in mice leads to an unusual course of coronary atherosclerosis, in which calcification precedes lipid deposition. The prevalence and significance of this mechanism in human atherosclerosis requires further investigations.

Abstract
Mid-face augmentation via a Le Fort I osteotomy is a commonly performed operation. Advancement of the upper jaw and associated structures (nose, lower cheek areas) can certainly improve function as well as facial aesthetics and harmony. Often, in patients with severe mid-face deficiency, hypoplasia of the maxilla extends all the way up to the infraorbital rims. The receding infraorbital rim contributes to the negative vector of the globes. In patients with this level of mid-face hypoplasia, while advancing the maxilla at the Le Fort I level satisfies all of the requirements for orthognathic surgery, the deficient infraorbital rim remains unchanged and can actually accentuate the negative vector of the globes. This article explains our approach in augmentation of the deficient infraorbital rim using alloplastic silicone implants at the time of a Le Fort I osteotomy.

Abstract
Objective:
Vascular calcification in asymptomatic individuals is an independent predictor of coronary heart disease (CHD). It is therefore plausible that vascular calcification plays a direct pathophysiological role in atherosclerosis, an underlying cause of CHD. The purpose of this study was to examine the contribution that vascular calcification has on the development of coronary atherosclerosis in a mouse model of familial hypercholesterolemia.
Approach and Results:
Calcification was induced by overexpression of tissue-nonspecific alkaline phosphatase (TNAP) in endothelial cells of mice harboring a point mutation in the low density lipoprotein receptor (
ldlr,
wicked high cholesterol, WHC). Mice were fed an atherogenic diet; echocardiographic and biochemical data were collected longitudinally. Atherosclerosis and vascular calcification were analyzed histologically in the aorta, aortic sinus and coronary arteries. TNAP mice were also treated with a combination of an atherogenic diet and a specific inhibitor of TNAP (SBI-425). Combined with the
ldlr
mutation and an atherogenic diet, TNAP-driven arterial calcification led to severe atherosclerosis with 100% morbidity characterized by occlusive coronary artery disease, pathological cardiac hypertrophy with dilated LV and reduced ejection fraction (EF). We detected an interaction between vascular calcification and atherosclerosis in mice with endothelial TNAP overexpression. This interaction was particularly prominent in coronary circulation. Targeting TNAP activity therapeutically helped improve survival and heart function of endothelial TNAP overexpressor mice, however the incomplete inhibition of TNAP by SBI-425 was a limitation of this study.
Conclusions:
Vascular calcification
via
TNAP overexpression in endothelial cells promotes coronary atherosclerosis and is pathogenic under conditions of hypercholesterolemia.

Abstract
AIM The purpose of the present study was to determine if there is a difference between multi-dose gonadotropin releasing hormone (GnRH) antagonist protocol and long GnRH agonist protocol. MATERIALS AND METHODS This retrospective study compared the data pertaining to patients chosen as per predetermined acceptance criteria, 113 of whom were administered multi-dose antagonist protocol for controlled ovarian hyperstimulation (COH) while 133 were administered long agonist protocol for COH at Suleymaniye Teaching Hospital of Obstetrics and Gynecology. RESULTS While cancellation rate was found to be significantly higher in antagonist group (17.7% vs 11.28%), the number of follicles > 14 mm and > 16 mm, E2 level, and the number of retrieved oocytes on the day of hCG trigger were significantly lower in the same group. However, there was no difference between fertilization rates and embryonic development rates. The pregnancy rates per transfer and per cycle were found to be 40.9% and 31.7%, respectively; in the antagonist group they were lower, though not significantly, when compared to agonist group (44.1% and 39.1%, respectively). Ongoing pregnancy rates were found to be similar between the groups. CONCLUSION GnRH antagonist treatment protocol has a level of efficacy similar to agonist treatment protocol in terms of pregnancy results for all groups.

Abstract
Background Diabetes mellitus is a chronic, progressive disease with complex therapy protocols requiring major coping efforts from patients to achieve and maintain glycaemic control in order to reduce risk of diabetic complications. Disease coping strategies including good knowledge of diabetes and high ability of self-care have been reported to be impaired by alexithymic features. Alexithymia is a psychological construct characterised by inability to express emotions verbally, poor imagination and operational thinking, leading to failure in psychological self-regulation. Objective To compare prevalence of alexithymia and mean Toronto Alexithymia Scale-26 (TAS-26) scores in diabetic patients with non-diabetic controls; to investigate the association of alexithymia with glycemic control in diabetes. Method In this cross- sectional study, TAS-26 scores of 193 diabetic patients and 49 non-diabetic controls were compared. Disease related factors were obtained from patient records. Alexithymia was used as a continuous (mean TAS-26 scores) and semi-quantitative (dichotomised into non-alexithymic 11>TAS-26 scores>11 and alexithymic individuals) variable. Descriptive data are presented as mean±SD, median (range) or %. Differences in means were compared via Independent-Samples T Test and One-Way ANOVA. Proportions were analysed with chi-square test and odds ratios (OR) were calculated via cross tabulation with a confidence interval (CI) of 95%. P<0.05 was considered statistically significant. Results The control group was similar with respect to age, gender and education with the diabetic group. In the diabetic study population (n=193, male/female: 42/58%, age 54.2±14.0 years, median diabetes duration 7 years (1-32 years), postprandial blood glucose (PBG) 243±110 mg/dl, HbA1c 7.3±3.6%) prevalence of alexithymia was significantly higher than in the control group (65 % in diabetics vs. 45 % in controls, p=0.011; mean TAS-26 score 12.3±3.7 vs. 10.6±3.6, p=0.004, respectively). Poor postprandial glycaemic control (p=0.002), female gender (p=0.026), combination therapy (p=0.037) and poor educational level (p=0.005) were positively associated with TAS-26 scores in diabetic individuals. Alexithymic diabetic patients were less educated (OR=1.2, p=0.046) and under worse glycaemic control (OR=2.4, p=0.005) compared to their non-alexithymic counterparts.

Abstract
Diabetes mellitus can cause cardiovascular autonomic neuropathy and is associated with increased cardiovascular deaths. We investigated cardiovascular autonomic neuropathy in diabetics and healthy controls by analysis of heart rate variability. Thirty-one diabetics and 30 age- and sex-matched controls were included. In the time domain we measured the mean R-R interval (NN), the standard deviation of the R-R interval index (SDNN), the standard deviation of the 5-min R - R interval mean (SDANN), the root mean square of successive R - R interval differences (RMSSD) and the percentage of beats with a consecutive R - R interval difference > 50 ms (pNN50). In the frequency domain we measured high-frequency power (HF), low-frequency power (LF) and the LF/HF ratio. Diabetes patients had lower values for time-domain and frequency-domain parameters than controls. Most heart rate variability parameters were lower in diabetes patients with chronic complications than in those without chronic complications.

Abstract
The management of upper facial trauma is a common responsibility of surgeons taking care of maxillofacial injuries. Historically, the most commonly used surgical approach has been the bi-temporal (coronal) incision. As is well known, the coronal incision carries some inherent complications such as hair loss, long scars, and increased length of hospital stay. The purpose of this article is to describe an aesthetic approach, similar to an endoscopic brow lift, for the repair of anterior wall fractures of the frontal sinus without the need for long incisions or fixation devices.

Abstract
OBJECTIVE To evaluate the complications of urinary incontinence surgery with transobturator tape (TVT-O) system and to describe its diagnosis and management. MATERIALS AND METHODS A total of 156 patients who were diagnosed as having stress incontinence and mixed incontinence with stress predominance underwent a TOT operation under spinal anesthesia by one surgeon or two surgeons (MB, AEY) from the team. TVT-obturator inside out material was used in the operation. Urodynamic tests and pad tests were done on all the patients. This is a prospective and retrospective study of the complications of TVT-O. The operation was performed under regional anesthesia, as described by Deval et al. Patients were excluded from the study if they had been operated under general or local anesthesia, had undergone any vaginal operations except for anterior repair (cystocele), wanted to have a baby, had severe systemic diseases or had been diagnosed as having urge incontinence in urodynamic tests. These situations may affect the rate of complications, the authors also excluded slings that had materials other than monofilament polypropylene, and patients who were suspected of having neurologic bladder conditions. The bladder and urethra were evaluated using cystoscopy. The durations of the TOT procedure, cystoscopy, and if performed, the cystocele operation, were recorded. Perioperative, early, and late postoperative complications were analyzed by follow-up visits (after two months to four years). RESULTS Of the 156 patients included in the study, 100 (64.1%) had pure stress urinary incontinence and 56 (35.9%) had mixed incontinence, 20 (12.8%) had previous incontinence surgery. The mean duration of follow up was 30.3 ± 7.4 (range 17-42) months. The mean age of the patients was found to be 48.43 ± 6.24 years (range 42-68). The mean parity of the patients was 5.24 ± 2.86 (range 2-13), and mean body mass index was found to be 23.7 ± 4.8. Mean maximum detrusor pressure was 10.30 ± 4.08 and the mean ALP value was 80.80 ± 25.57. Mean operative time was found to be 13.8 ± 5.16 min in patients who underwent only TOT and TOT-anterior repair. Vaginal injury including to the lateral fornix (4.4%), hemorrhaging of more than 200 ml (3.2%), vascular damage (1.9%), hematoma on the leg (1.9%), hemorrhaging of more than 500 ml (0.064%), and bladder perforation (1.2%) were detected as perioperative complications. Urethral injury and perioperative nerve and intestinal injury did not occur. The most common complication in early postoperative period was inguinal pain extending the legs (30.7%), followed by headaches (23.7%), fever (12.8%), urinary tract infection (5.7%), and urinary retention (3.2%), respectively. Late postoperative complications included vaginal erosion (4.4%), de novo urge incontinence (8.9%), de novo dyspareunia (7.1%), perineal pain (4.4%), and worsening urgency (8.9%). CONCLUSION Although the TVT-O technique is a minimal invasive surgery method applied to treat the urinary incontinence surgically, it does not imply that it is a complication-free surgical procedure. Despite the low incidence of intraoperative complications, there is a mild risk of early and late postoperative complications. Fortunately these complications can be taken under control by either conservative and simple medical treatments or surgical procedures.

Abstract
OBJECTIVE The aim of this study was to evaluate serum cardiac troponin I and D-Dimer (D-Di) levels in preeclampsia (PE), eclampsia (E), and normotensive healthy pregnant women in third trimester in order to define their diagnostic value. MATERIALS AND METHODS The study group consisted of 42 preeclamptic patients and 16 eclamptic patient; 108 healthy normotensive pregnant women in third trimester who were chosen from outpatients clinic and examined regularly used as a control group. Serum cardiac troponin I and D-Di levels were measured using an immunoassay. RESULTS The average levels of troponin I were 0.0134 ± 0.0091, 0.017 ± 0.0085, 0.180 ± 0.136 in control group, preeclamptic, and eclamptic patients, respectively. The levels of troponin in eclamptic patients were statistically higher than the normotensive and preeclamptic group (p = 0.016, p = 0.014). There were no differences in terms of troponin I level between preeclamptic group and normotensive pregnant women in third trimester (p = 0.089). The average D-Di levels were 634 ± 228 ng/ml, 1426 ± 430 ng/ml, 2067 ± 580 ng/ml in control group, preeclamptic, and eclamptic patients, respectively. The levels of D-Di in preeclamptic and eclamptic patients were found significantly higher than the control groups (p = 0.034, p = 0.020). CONCLUSION Serum troponin I levels increased in eclamptic patient because of myocardial damage. An increased level of troponin was not detected in preeclamptic patients. However; D-Di level increased in preeclamptic and eclamptic patients.

Abstract
AIM To evaluate the safety and effectiveness of insulin analogues (insulin aspart, insulin detemir and biphasic insulin aspart 30, alone or in combination) in type 2 diabetes mellitus (T2DM) patients in routine clinical practice in the Gulf as a subgroup of the A(1) chieve multi-national study. METHODS A total of 10,704 T2DM Gulf patients with uncontrolled T2DM on oral antidiabetics ± insulins other than insulin aspart, insulin detemir or biphasic insulin aspart 30, who initiated or switched to study insulins were included and followed up for 24 weeks in the context of the A(1) chieve study. RESULTS Baseline HbA(1c) (± SD) was poor: 9.7 ± 1.7%. At Week 24, an improvement in HbA(1c) of -2.3 ± 1.6% was observed in the entire cohort, and -2.4 ± 1.5% and -2.1 ± 1.7% for insulin-naïve patients and prior insulin users respectively. Overall, rates of hypoglycaemia increased in those new to insulin therapy, whereas a reduction was observed in those switching from other insulins. A marginal reduction in body weight (-0.8 ± 4.4 kg) was noted in the entire cohort, whereas the overall lipid profile and systolic blood pressure (-6.2 ± 15.3 mmHg) improved. CONCLUSIONS Initiating or switching to insulin analogues was well tolerated and resulted in significant improvements in glycaemic control in T2DM patients in the Gulf.

Abstract
The essential therapy of diabetes mellitus includes medical nutrition therapy (MNT), exercise and medical therapy. Exercise, besides its metabolic effects, has positive influence on the immune system, but some forms of exercise may cause trauma for muscle and skeletal systems, they may also support negative effects on the immune system. Nineteen type 1 diabetic patients (mean age 22.1 +/- 2.8 yrs), followed by Diabetes Outpatient Clinic and twenty age matched male control subjects were included into the study, to demonstrate the effects of maximal, acute exercise on the immune system. The exercise test was performed according to Bruce protocol on treadmill. In diabetic subjects, increased CD19 and CD23 expressions were observed before exercise. In both groups (diabetic/control) CD3, CD4 expressions and CD4/CD8 ratio were decreased following the exercise, however expression of natural killer (NK) cells increased. Compared to type 1 diabetic patients healthy subjects had longer acute exercise that caused the increased level of CD8 expression, however type 1 diabetic patients did not show any difference. These results indicate that submaximal aerobic exercise might be recommended for type 1 diabetics without any complications because of its positive reflection on metabolic control and no negative effects on the immune system.

Abstract
Periodontal conditions in 100 dentate adults with rheumatoid arthritis (RA) were compared with those of age and gender matched individuals without rheumatoid arthritis. The clinical parameters for periodontitis included probing pocket depths, attachment loss, gingival inflammation scores, plaque scoresand radiographic bone loss scores. The rheumatoid arthritis group had more missing teeth than the control group and a higher percentage of them had deeper pocketing and loss of periodontal attachment There were no significant differences between the two groups for gingival inflammation and bleeding. There was a tendency to adverse periodontal conditions amongst the rheumatoid arthritis patients with severe periodontal bone loss occurring more frequently than in the controls. The rheumatoid arthritis patients had more dental plaque deposits than the control group, a finding which could indicate a difference in periodontal care. It is suggested that this study provides evidence of a significant association between periodontitis and rheumatoid arthritis.

Abstract
With the increasing life expectancy, osteoporosis is becoming a major worldwide health problem. The magnitude of the disease may become larger in developing countries, more particularly in the Middle East region where the prevalence of low bone mass is higher than in western countries. Although several local organizations and countries have developed guidelines for osteoporosis, no previous regional guidelines have been developed encompassing all Middle-Eastern and North African countries. The present document reviews all the regional published data on bone mineral density, risk factors, fracture prevalence and vitamin D status. It also gives simple recommendations applicable to all these countries. This document was endorsed by leading members of all the different regional countries including, Iran, Egypt, Tunisia, Jordan, Palestine, Syria, Iraq, Libya, Oman, Kuwait, Saudi Arabia and Bahrain.
