Abstract
Laryngeal mirror (LM) is an inexpensive, portable, readily available device which can help visualize the vocal cords in difficult airway (DA) situations. We evaluated its use in improving glottic view prior to placing the airway adjuncts in simulated difficult airway.Eighty patients scheduled to undergo elective surgery under general anaesthesia with endotracheal intubation were allocated- Bougie group (Group B) and Stylet group (Group S). Direct laryngoscopy was performed and CL grade III simulated. The glottic view was obtained using laryngeal mirror and Gum Elastic Bougie (GEB)/ Styleted Endotracheal Tube (ETT) inserted under mirror view. Time taken to obtain glottic view in LM and time for successful intubation were noted.Significant improvement in glottic view with LM was observed, with the view improving to Grade I in 76.25% and grade II in 23.75% of patients. Both groups were comparable with respect to number of attempts and success rate (p = 0.55).The success rate was 90% in group B and 95% in group S. Time taken for intubation was less in Group S (52.44 ± 14.23 s vs. 62.805 ± 20.74 s) [p = 0.01]. Hence, overall stylet proved to be a better adjunct with mirror guided intubation.We recommend stylet assisted rather than GEB assisted ET intubation under LM guidance in emergency scenarios. Also, further controlled trials are recommended to know the exact location of the mirror in relation to bulb of the laryngoscope as well as different angles at which it is placed to improve the view and stabilize the assembly.

Abstract
To report the visual and refractive outcomes of new aspheric hydrophobic acrylic monofocal intraocular lens (IOL). Retrospective case series. This study included eyes of patients who underwent routine cataract surgery for uncomplicated age-related cataract with implantation of a Aktis SP (NS-60YG; Nidek Co. Ltd., Japan) IOL and attended regular follow ups at 1 week, 1 month, 3 months, and 12 months. At each post-operative visit, ophthalmological evaluation included measurement Uncorrected (UCVA) and Best corrected visual acuity (BCVA), contrast sensitivity, posterior capsular opacification (PCO), optical aberrations, analysis of point spread function (PSF) and modulation transfer function (MTF). The study included 2102 eyes of 1358 patients aged 45 to 75 years (mean age 62.6 years ± 5.6 SD). The mean preoperative BCVA was 0.56 ± 0.26 logMAR. At 1 year follow up, the mean postoperative UCVA and BCVA were 0.11 ± 0.09 and 0.02 ± 0.03 logMAR, respectively. At the end of 6 months, around 1487 (93%) eyes had BCVA of 20/20 and better than 20/30 in 100% of the eyes. Mild posterior capsule opacification (PCO) was observed in 56 patients, but none required Nd YAG laser capsulotomy. There was reduction in ocular spherical aberration and Higher order aberrations (HOAs) as compared to pre operative. This explains better contrast sensitivity obtained by MTF and PSF values. The study shows that the Aktis SP IOL is safe, effective, and stable lens that could be inserted through 2.2 mm incision with satisfactory visual and refractive outcomes, even in late post-operative period.

Abstract
Introduction PTS (pneumatic transport system) is extensively being used in modern hospitals for rapid transportation of blood samples and other specimens. However, it has a potential impact on blood components, which should be investigated and nullified accordingly. This study was part of a correction program aimed at reducing hemolysis. It was done by comparing paired samples transported manually and by PTS.
Materials and Methods This study was initiated to monitor the impact of PTS on hemolysis of clinical biochemistry blood samples. It was performed in two phases—before and after the corrective action taken. Phase I: done after PTS installation but before the corrective action was taken. Duplicate samples from 100 healthy individuals were collected, one set transported by PTS and the other by human carriers. Both sets were assessed for 25 biochemistry analytes, hemolysis index (HI), and acceleration profiles using a data logger. Corrective measures were then taken, followed by phase II of the study. In phase II, the sample size and study design remained the same as phase I. All the test results of PTS and hand-carried samples were statistically analyzed for any significant difference.
Result In phase I, all the hemolysis-manifesting parameters, LDH (lactate dehydrogenase), potassium, AST (aspartate transaminase), and phosphorus, were raised in PTS samples as compared with the manual samples. Their differences were significant as the p-values were 0.001, 0.000, 0.025, and 0.047, respectively. The differences for LDH and potassium were clinically significant as well. HI (9%) and peak acceleration (15.7 g) were high in PTS samples.In phase II, no statistically significant difference between paired samples was found for all biochemistry parameters except for a few which were clinically nonsignificant. For PTS samples, HI was 2.5% and the peak acceleration was 11.2 g, whereas for manual samples, HI was 2%.
Conclusion Evidence of hemolysis was found in PTS samples as compared with handheld samples, which was resolved after several corrective actions were taken. Thereafter, PTS became reliable for sample delivery in a routine biochemistry laboratory. Hence, each hospital should scrutinize their PTS for its effects on sample integrity to get rid of PTS-induced preanalytical errors.

Abstract
INTRODUCTION Unilateral uveo-meningeoenchephalitic syndrome is a relatively rare entity. Our case highlights the importance of keeping this entity in mind when a unilateral picture suggestive of Vogt Koyanagi Harada syndrome crops up. CASE A 34-year-old male came with chief complaints of blurring of vision in the right eye since two days with a prodrome of intense headache and redness in the right eye. On examination, the vision in the right eye was counting fingers close to face and 20/20 in the left eye. Clinical examination suggested unilateral uveo-meningeoenchephalitic syndrome which was confirmed on multimodal imaging. OBSERVATIONS This case highlights the fact that though uveo-meningeoenchephalitic syndrome is bilateral, by definition; the initial presentation may still be unilateral and a prompt diagnosis and treatment can prevent the involvement of the other eye. CONCLUSION Any case presenting with signs of symptoms suggestive of Vogt Koyanagi Harada should be treated as Vogt Koyanagi Harada even though the initial presentation may be unilateral. A prompt diagnosis and early treatment will ensure that the other eye does not get involved. Early Vogt Koyanagi Harada may just present with choroidal hyperpermeability and multiple septate pockets of SRF without any vitreous cells or anterior segment inflammation.

Abstract
Performing capsulorhexis in white intumescent cataracts during phacoemulsification surgery is challenging for cataract surgeons because of high intralenticular pressure and reduced red reflex. Capsulorhexis extension to the periphery of the lens is a common occurrence due to lens intumescence. We used a vitrectomy cutter to create an initial tear in the anterior capsule and simultaneously remove a part of milky fluid coming out of the intumescent lens. Once the lens was decompressed, capsulorhexis was completed using capsulorhexis forceps. This technique helped in controlling capsulorhexis in eyes with intumescent cataracts by reducing the intralenticular pressure and thereby preventing unexpected radial capsular tear.

Abstract
Background Evidence supports the association between exercise and outcomes following bariatric surgery. However, there is a lack of knowledge regarding the short-term benefits of preoperative exercise. Objectives The objective of this pilot study was to evaluate the feasibility and functional benefits of a 12-week preoperative exercise program in patients awaiting bariatric surgery. The primary aim was the six-minute walk test (6MWT). The secondary aim of this study included anthropometric measures, strength, and quality of life. Methods A total of 54 patients were enrolled in this pilot randomized controlled study. Of them, 29 patients received standard multidisciplinary preoperative care, while 25 patients participated in a 12-week supervised exercise program in addition to standard preoperative care consisting of strength and aerobic exercises three times per week in a fitness facility. The primary outcome was improvement in 6MWT. Secondary outcomes included other functional outcomes, quality of life, and anthropometric measures. Results Average attendance for the intervention group was 27.2 (75.6%) of 36 sessions. There was a mean improvement of 27 ± 10 meters in the intervention group compared with a reduction of 5 ± 10 meters in the control group (p = 0.003). Patients in the intervention group had significant improvement in all self-reported quality-of-life domains, particularly in the variables related to symptoms, hygiene, and emotions. Conclusions A 12-week preoperative exercise intervention was feasible and showed association with a statistically significant improvement in 6MWT and quality-of-life measures in patients awaiting bariatric surgery. The results of this study will inform sample size calculations and recruitment planning for a future study that will assess the longer-term benefits of a pre-surgical fitness intervention.

Abstract
Objective This study was conducted to determine the risk factors and feto-maternal outcomes in uterine rupture at a tertiary care centre, with the goal to assess the delays or gaps in management, in order to avert associated morbidity and mortality. Material and methods This study was conducted from June 2018 to May 2020 in Vardhman Mahavir Medical College & Safdarjung Hospital, New Delhi, wherein all women diagnosed with uterine rupture, either at the time of admission or during the course of hospital stay, were included after taking written informed consent. The primary outcome measured was the incidence of uterine rupture, whereas the secondary outcomes assessed were clinical features, risk factors, per-operative findings, management, and feto-maternal outcomes. Results The total number of deliveries during the study period was 67005. Out of these, 12985 women underwent LSCS, whereas others delivered vaginally. A total of 61 cases of uterine rupture occurred among them. The majority of these women were unbooked (62.29%), having a gestation age >37 weeks (65.57%). The most common risk factor identified was a history of previous LSCS (91.80%). Around 80.33% of women had rupture of the lower segment of the uterus. Maximum cases were managed by repair with ligation (63.93%), while 26.22% underwent hysterectomies. Bladder injury occurred in 11.48% of women. While most of the women required blood transfusion (93.44%), only three maternal deaths occurred. Conclusion Rupture of a gravid uterus can be a lethal surgical catastrophe with potentially grave feto-maternal consequences. Alacrity in diagnosis and referral to a tertiary centre, along with facility-level preparedness to respond to this emergency, apart from optimal care around birth, are critical determinants for feto-maternal survival.

Abstract
Blood urea nitrogen and serum albumin levels are independent risk factors for poor clinical outcome in CAP. However, there is a paucity in the literature on the role of Blood urea nitrogen and albumin ratio(B/A) in CAP. This was a prospective observational study in which 112 admitted patients with the diagnosis of CAP underwent routine blood examinations, ABG, procalcitonin and Chest X-ray. Univariate analysis among various risk factors, CURB-65 scores, blood parameters including B/A ratios and clinical outcomes were carried out followed by multiple logistic regression. Cox regression was done to look at B/A values and time to mortality. In the logistic regression, age, CURB -65 score, B/A ratio and procalcitonin came out to be independent risk factors for ICU admission and mortality. Odds ratio of B/A in predicting mortality and ICU admission came out to be 67.8 (49.2-95.4) and 11.2 (8.4-14), respectively. Cox regression showed B/A values were also found to have a statistically significant relationship with time to mortality (p=0.001). B/A ratio has the potential to become a veritable predictor of poor clinical outcomes in patients with CAP.

Abstract
The big bubble technique has become the technique of choice for performing deep anterior lamellar keratoplasty (DALK) since its inception in 2002. The main challenge with this technique is in achieving a big bubble while preventing inadvertent perforation of the Descemet's membrane. Although femtosecond lasers have increased the safety, accuracy, and predictability of corneal dissection in DALK, the challenge of achieving a big bubble still exists. To overcome this challenge, Zeimer Z8 Femto LDV has launched a new software module for DALK, which has an added advantage of real-time optical coherence tomography-assisted femtosecond tunnel creation for achieving a big bubble.

Abstract
The purpose is to present the outcomes of anterior lamellar keratoplasty for a case of post-laser in situ keratomileusis (LASIK) epithelial ingrowth. A 40-year-old male patient presented with epithelial ingrowth 14 years after primary LASIK with a microkeratome blade in the right eye following trauma. Multiple stromal bed washing was done over a period of 3 years, but recurrence of epithelial ingrowth was seen every time. Femtosecond laser-assisted anterior lamellar keratoplasty was performed in the right eye. Twelve months after the procedure, the patient's corrected distance visual acuity improved to 6/9, and no recurrence was noted. Femtosecond laser-assisted anterior lamellar keratoplasty is an effective treatment modality in cases of recurrent recalcitrant epithelial ingrowth seen after LASIK.

Abstract
Disseminated Histoplasmosis, a systemic fungal infection caused by Histoplasma capsulatum is predominantly seen in immunocompromised cases. It is usually endemic, although sporadic cases have been reported. Following initial infection to the lungs, it disseminates to various organs by lymphatic and hematogenous routes. Clinical features are non-specific and depend on the extent and severity of organ involvement. A Biopsy is required for diagnosis and timely intervention decreases morbidity and mortality. Our case report describes an atypical association of progressive disseminated Histoplasmosis with bone marrow involvement in an immunocompetent adult from a non-endemic region and alerts the clinicians to a rare yet life-threatening mycosis.

Abstract
Marfan syndrome (MFS) is known to cause significant refractive error. Treatment options are limited in this condition for correcting refractive error. Clear lens exchange is done in these cases, but complication rates are high. Loss of accommodation is another concern in these young adults. We report toric phakic intraocular lens (pIOL) implantation in improving the uncorrected visual acuity (UCVA) in a known case of MFS with lens coloboma. A 22-year-old female patient with MFS with inferior lens coloboma underwent bilateral toric pIOL implantation in the same sitting. Pre- and post-operative UCVA and best-corrected visual acuity were assessed. Central and peripheral vaulting of the pIOL in relation to the natural lens was also assessed. UCVA improved from 20/500 to 20/20 in the right and 20/550–20/20 in the left eye. Marked central vaulting with partial peripheral vaulting was achieved. There were no post-operative complications. Phakic IOL implantation surgery could be an effective approach to achieve excellent uncorrected refractive outcome in patients with MFS to treat high myopia.

Abstract
Interstitial lung diseases (ILDs) are a frequently occurring pulmonary manifestation in patients of connective tissue diseases (CTD). Detailed understanding of this subset of lung diseases is vital, hence the study was conducted to analyze the clinico-radiological characteristics of CTD-ILD. The present study was conducted between March 2017 to February 2018 at a tertiary care teaching hospital from western India. A total of 100 patients having respiratory symptoms suggestive of ILD, who were either diagnosed cases of CTD or had clinical manifestations of underlying CTD, were included in the study. 27% of patients belonged to age group 41-50 years and 78% were females. Chief respiratory complaints were dyspnea and cough. Clubbing was present in 29% patients. The most common CTDs were rheumatoid arthritis [RA] (26%), systemic sclerosis [SSC] (21%), mixed connective tissue disorder [MCTD] (19%) and Sjogren's syndrome [SS] (16%). Restrictive defect on spirometry was seen in 58% cases and was most significant among patients with RA (65%) and SS (62%). Pulmonary arterial hypertension was seen in 40% cases and was most evident in MCTD (78%) and SSC patients (58%). Chest radiograph was normal in 47% of subjects. Most common radiological pattern on high resolution computed tomography (HRCT) thorax was non-specific interstitial pneumonia (42%) followed by usual interstitial pneumonia (21%). ILD is a common manifestation of CTD. Work-up for an underlying CTD should be offered to all ILD patients and vice versa.

Abstract
We report a rare case of bilateral keratoglobus with hypermature intumescent cataract in a 55-year-old woman. Clinical examination and corneal topography confirmed generalized corneal bulging and global corneal thinning. A Pentacam® (Oculus Optikgerate, Wetzlar, Germany) demonstrated bilateral diffuse corneal thinning (368 μm in the right eye and 371 μm in the left eye). Phacoemulsification was performed in the right eye after thorough workup and modification of the surgical technique. This case report helps in better understanding of the challenges of cataract surgery and intraocular lens selection in a keratoglobus patient, and stresses the need for both thorough preoperative planning and intraoperative surgical modifications.

Abstract
PURPOSE To evaluate stereopsis and visual quality after bilateral implantation of extended range of vision intraocular lenses (ERV IOLs). SETTING R.P. Centre for Ophthalmic Sciences, AIIMS, New Delhi, India. DESIGN Prospective interventional study. METHODS Patients underwent phacoemulsification with bilateral implantation of ERV IOLs. The primary outcome measures were stereopsis (distance and near Randot) and visual quality (ray-tracing aberrometry). The secondary outcome measures were visual acuity and patient satisfaction. Follow-up was performed on day 1 and at 1, 3, 6, and 12 months postoperatively. RESULTS The study comprised 50 patients (100 eyes). The mean age of the patients was 58.9 years ± 8.9 (SD). At 1 year, the mean distance stereopsis was 103.6 ± 49.1 seconds of arc (arcsec) and near stereopsis was 21.1 ± 2.3 arcsec. Perfect near stereopsis of 20 arcsec was present in 80% of cases, and 82% had good distance stereopsis of 100 arcsec or better. Stereopsis correlated well with the patient satisfaction score (P < .001) and average internal modulation transfer function (MTF) (P < .015). The mean Strehl ratio was 0.029 ± 0.021, MTF was 0.24 ± 0.08, total higher-order aberrations were 0.62 ± 0.41 μm, and coma was 0.25 ± 0.18 μm. The mean binocular uncorrected decimal visual acuities were 0.98 ± 0.07 (distance), 0.82 ± 0.09 (intermediate) and 0.64 ± 0.08 (near). The mean patient satisfaction score was 9.08 ± 1.1, and no case required IOL explantation because of visually disturbing phenomena or patient dissatisfaction. CONCLUSION Excellent stereoacuity was observed after bilateral implantation of ERV IOLs, which correlated well with patient satisfaction and quality of vision.

Abstract
Background: Nonmuscle invasive bladder cancers (NMIBC) are one of the most common urological cancers having a high risk of recurrence and progression. Recurrent tumors may acquire certain molecular alterations responsible for progression of the tumors. Identification of these alterations is important to understand the pathobiology and guide further management. Aim: We studied the differences in expression of cell surface proteins and cell cycle signaling molecules in primary and recurrent NMIBC by immunohistochemistry (IHC) on tissue microarrays (TMA). Methods: Using FFPE tissue, TMA of 82 tumors (40 primary NMIBC and 47 recurrences) were constructed. IHC for growth factor receptors [epidermal growth factor receptor (EGFR), HER2/neu and FGFR3], cell adhesion molecules (E-cadherin and beta-catenin) and cell cycle pathway molecules (p53, p21/WAF1/Cip1 and Ki-67 proliferation index) was performed. A semiquantitative H-score (Histo-score; range 0-300) was calculated according to the intensity (0, negative; 1, weak; 2, moderate; and 3, strong) and percentage of cells stained. < 10% cells showing nuclear p21 expression was considered p21-loss. The differences in expression between the primary and recurrent tumors were analyzed using paired t test. Results: The mean age at presentation was 65.3 ± 13.6 years with a male predominance (n=36). The mean time to recurrence was 33.4 months (range 3-109). Progression in grade and/or stage was seen in 30 (75%) tumors. Time to recurrence was shorter in primary tumors with ≥ 5% Ki-67 proliferation index. There was no significant difference in expression of cell surface proteins between primary and recurrent tumors. Significant p21 loss was seen in recurrent tumors ( P = 0.03) and significantly correlated with loss of surface beta-catenin and nuclear p53 positivity ( P = 0.002). Ki-67 index was higher in recurrent tumors and also correlated with p53 positivity ( P = 0.007). Conclusion: We found no significant differences in expression of cell surface molecules in primary nonmuscle invasive bladder cancers and their recurrences. However, there were significant alterations in expression of molecules of cell cycle signaling pathway and cellular proliferation in recurrent tumors suggesting the role of cell cycle regulators as promising targets in these cancers.

Abstract
Previous research has indicated that active adults are able to achieve moderate intensity as measured via heart rate during a typical resistance training (RT) session. The main objective was to identify if overweight adults and older adults can reach aerobic moderate intensity at a rate comparable to adults displaying a recommended body mass index. Twenty participants in each group were asked to visit a fitness facility twice if they self-reported doing RT for a minimum two days per week. At the first session baseline characteristics and maximal lifting capacity for each RT exercise. At the second, intensity was monitored via heart rate monitor during a RT exercise program composed of 10 exercises targeting major muscle groups. Three sets of 10 repetitions at 70% of maximal load were completed for each exercise. Moderate intensity was defined as a minimum of 40% of heart rate reserve. The proportion of time spent at moderate to vigorous intensity between the comparison group and the overweight adult group was not significantly different, with a median (25th-75th) proportion time of 82.6% (69.2-94.6) versus 92.5% (73.3-99.1); p=.54 or an average time of 42 minutes versus 45 minutes. The older adults group, however, spent a lower proportion of time at moderate to vigorous intensity compared with the comparison group, 51.5% (22.0-86.6) or 24 minutes; p<.01 compared with the comparison group. This study suggests that a good proportion of time spent doing RT can contribute to an aerobic component of the international guidelines, and therefore reduce the weekly time commitment especially for men and women age below 60 years old.

Abstract
BACKGROUND Physical activity is a routine component of the lifestyle modification program implemented prior to bariatric surgery, and one of the goals is to improve patients' physical capacity. However, the physical activity intensity recommended to meet that goal is unknown. OBJECTIVE This study aimed to assess the association between time spent at different physical activity intensities and physical capacity in patients awaiting bariatric surgery. MATERIALS AND METHODS A total of 39 women and 13 men were recruited. The primary outcome was physical capacity measured using six objective tests: 6-min walk, chair stand, sit and reach, unipodal balance (eyes open and eyes closed), and hand grip strength tests. The primary exposure variable was physical activity intensity (i.e., sedentary, light, moderate, and vigorous) measured by accelerometers. RESULTS The average body mass index was 46.3 ± 5.4 kg/m2. Only 6% of total time was spent at moderate to vigorous intensity, while 71% of the time was spent sedentary. When adjusted for body mass index, age, and sex, four of the six physical capacity tests were significantly associated with moderate intensity physical activity β(SE): 6-min walk 9.7 (2.7), chair stand 0.3 (0.1), balance (eyes open) 1.8 (0.7), and hand grip strength 1.2 (0.4), and only the 6-min walk was associated with sedentary activity 1.7 (0.7). CONCLUSION These results suggest that physical capacity is associated with time spent at moderate intensity in individuals awaiting bariatric surgery. The next step is to study if an increase in time spent at moderate intensity will translate to improvements in physical capacity.

Abstract
This prospective, randomised, observer-blinded study was conducted to compare the ease of performance and surgical effectiveness of interscalene block below the C6 nerve root with supraclavicular and infraclavicular techniques of brachial plexus block for upper arm and forearm surgery. Sixty adult patients of American Society of Anesthesiologists grade 1 to 3, undergoing upper limb surgery, were randomly allocated into three groups. Group SC received supraclavicular blockade, group IC received infraclavicular blockade and Group IS received interscalene blockade. All blocks were guided by ultrasound with nerve stimulator confirmation. The anaesthetic mixture consisted of 0.5 ml/kg of equal volumes of 0.75% ropivacaine and 2% lignocaine-adrenaline. The imaging and block performance time, onset time, success rate, duration of block, and duration of postoperative analgesia were recorded by a blinded observer. The onset time was significantly longer in the interscalene group as compared with supraclavicular and infraclavicular approaches. The imaging time and block performance time were comparable between groups. No significant differences were observed between the three groups in terms of block-related pain scores, success rates, duration of block or of postoperative analgesia. Two patients in the interscalene group developed clinically detectable phrenic nerve palsy. Our findings indicate that, although interscalene block below the C6 nerve root can provide surgical anaesthesia for forearm and hand surgery, it appears to have a longer onset time than supra- and infraclavicular approaches and an unacceptable incidence of phrenic nerve palsy.

Abstract
BACKGROUND This randomized double-blind study was designed to compare palonosetron with palonosetron-dexamethasone combination for prevention of post operative nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy. METHODS Eighty-four adult ASA 1-2 patients were randomly allocated into two groups. Group P patients received 0.075 mg palonosetron and group PD patients received 0.075 mg palonosetron and 8 mg dexamethasone intravenously before induction of anesthesia. Anesthesia was induced with propofol and fentanyl and maintained with N2O-isoflurane in oxygen. All patients received port-site infiltration with bupivacaine and intravenous diclofenac for postoperative analgesia. Metoclopramide was used as rescue antiemetic. Patients were observed for the incidence of PONV and requirement of rescue antiemetic for 48 h after surgery. RESULTS The complete response rate (no vomiting) was significantly higher in group DP as compared to group P between 0-24 h (P=0.004). 18 (42.9%) patients reported nausea and 14 (33.3%) patients had vomiting in group P while 6 (14.4%) patients had nausea and 5 (11.9%) patients complained of vomiting in group DP during 0-24 h. Two patients in group P reported nausea while none in group PD during 24-48 h. No patient had vomiting in either of the groups between 24-48 h. The requirement of rescue antiemetic was also less in group DP as compared to group P. Patients in group DP required less postoperative analgesia and were more satisfied with PONV treatment than group P patients. CONCLUSION The palonosetron-dexamethasone combination was more effective as compared to only palonosetron for reducing PONV after laparoscopic cholecystectomy.

Abstract
Prediabetes is defined as impaired fasting glucose and/or impaired glucose tolerance. Impaired fasting glucose is usually defined as fasting blood glucose between 5.6 mmol/L and 6.9 mmol/L (100.8-124.2 mg/dL), and impaired glucose tolerance is the 2-hour oral glucose tolerance test of 7.8-11.0 mmol/L (140.4-198.0 mg/dL). Most individuals with prediabetes are overweight or obese and are at greater risk of type 2 diabetes (T2D). The first line of treatment for individuals with prediabetes is lifestyle modification, including diet and exercise. The aim of this review, through the revision of primarily randomized control trials, is to discuss the independent and combined effect of diet and exercise on the incidence of T2D, glycemic control, and weight loss in adults with prediabetes. Based on the available literature, lifestyle modification combining both diet and exercise is effective at reducing the incidence of T2D and improving glycemic control, even without a significant reduction in body weight. Thus, it is unclear whether weight loss, through lifestyle modification, is a cornerstone for improving glycemic control in individuals with prediabetes. The independent effect of diet or exercise alone on the improvement in glycemic control and/or reduction in body weight in individuals with prediabetes still requires more studies to draw a clear conclusion, considering the quality and quantity of available studies. As of now, the best diet and/or exercise program to improve glycemic control and body weight in adults with prediabetes is unknown.

Abstract
OBJECTIVES This randomized double-blind study was designed to compare the postoperative analgesic effect of clonidine administered intravenously or in wound infiltration with bupivacaine. METHODS Sixty adults of ASA grade I-II undergoing open cholecystectomy were randomly allocated into three groups. Group 1 (control group) patients received wound infiltration with 30 ml of 0.25% bupivacaine at the end of surgery. Group 2 patients received 3 μg kg(-1) clonidine intravenously after resection of gall bladder plus wound infiltration with 30 ml of 0.25% bupivacaine. Group 3 patients received wound infiltration with 3 μg kg(-1) clonidine with 30 ml of 0.25% bupivacaine. A standard general anaesthesia technique was used. Postoperative analgesia was provided with i.v. diclofenac and morphine on demand. Postoperative pain, number of patients requiring rescue analgesia and total morphine consumption during 24 h after operation was recorded. RESULTS Postoperative morphine consumption was significantly less in patients receiving clonidine by either route when compared with the control group (P<0.0001). All patients in the control group required supplemental morphine, with nine patients in the i.v. clonidine group and 11 patients in the wound infiltration group (P<0.002). Pain scores were lower at rest for 12 h and on cough for 6 h in both clonidine groups when compared with the control group (P<0.01). Patients receiving i.v. clonidine had more hypotension (P<0.01) and sedation (P<0.001) compared with other groups. CONCLUSIONS Clonidine 3 μg kg(-1) provided effective postoperative analgesia and reduced morphine requirement when administered intravenously or in wound infiltration with bupivacaine. However, the incidence of complications was less with wound infiltration. CLINICAL TRIAL REGISTRY OF INDIA: (www.ctri.nic.in/), registration number CTRI/2012/12/003258.

Abstract
This randomised, double-blind study was designed to compare the duration of analgesia and adverse effects following intrathecal administration of dexmedetomidine or clonidine, both with bupivacaine, in trauma patients. Ninety adult trauma patients of American Society of Anesthesiologists physical status I-II, scheduled for lower limb surgery under subarachnoid block, were randomly allocated to one of three groups. All groups received hyperbaric bupivacaine 0.5% 3 ml, to which was added saline 0.5 ml (Group B): clonidine 50 µg (Group C) or dexmedetomidine 5 µg (Group D). The onset and duration of sensory and motor blockade, severity of postoperative pain, time to first rescue analgesia and total analgesic requirement for 24 hours were noted. There was no significant difference in the onset time of the block but the duration of sensory and motor blockade was prolonged in Groups C and D, compared with Group B. The time to analgesia was significantly prolonged in Group D (824±244 minutes) compared with Group C (678±178 minutes; P=0.01), the latter being longer than Group B (406±119 minutes; P=0.0001). Postoperative pain scores were lower in Groups C and D compared with group b. The requirement for rescue analgesia during the first 24 postoperative hours was significantly less in Groups C and D as compared to Group B (P=0.0001), but comparable between Groups C and D (P=0.203). In conclusion, dexmedetomidine 5 µg added to intrathecal bupivacaine 15 mg produces longer postoperative analgesia than clonidine 50 µg among trauma patients undergoing lower limb surgery.

Abstract
Throughout the African meningitis belt, meningococcal meningitis outbreaks occur only during the dry season. Measles in Niger exhibits similar seasonality, where increased population density during the dry season probably escalates measles transmission. Because meningococcal meningitis and measles are both directly transmitted, we propose that host aggregation also impacts the transmission of meningococcal meningitis. Although climate affects broad meningococcal meningitis seasonality, we focus on the less examined role of human density at a finer spatial scale. By analysing spatial patterns of suspected cases of meningococcal meningitis, we show fewer absences of suspected cases in districts along primary roads, similar to measles fadeouts in the same Nigerien metapopulation. We further show that, following periods during no suspected cases, districts with high reappearance rates of meningococcal meningitis also have high measles reintroduction rates. Despite many biological and epidemiological differences, similar seasonal and spatial patterns emerge from the dynamics of both diseases. This analysis enhances our understanding of spatial patterns and disease transmission and suggests hotspots for infection and potential target areas for meningococcal meningitis surveillance and intervention.

Abstract
To examine and improve outcomes of resident-performed manual small incision cataract surgery (MSICS) cases via analysis of visual recovery, intraoperative adverse events, and early postoperative course. Particular focus was directed toward mature cataracts extracted by MSICS. A retrospective review was performed to identify MSICS cases performed by resident surgeons unfamiliar with the technique (initial ten cases) in an academic setting. Preoperative history, intraoperative adverse events, and postoperative course were reviewed. Of 30 cases identified, mean preoperative acuity was 1.8 ± 0.9 logMAR units (Snellen equivalent = 20/1262) improving to 0.20 ± 0.35 logMAR units (20/31) at final follow-up (p < 0.0001). Mean follow-up was 22.1 ± 19.0 days. The most frequent intraoperative adverse events were wound leak requiring intraoperative suturing (33 %), vitreous loss (6.7 %), and capsulorhexis radialization (6.7 %). Transient cornea edema was the most frequent (56.7 %) early postoperative minor complication. Two major complications occurred that required wound revision in one eye and iridoplasty in one eye. Of the 30 eyes undergoing surgery, 19 were noted to have mature cataracts. In this subset, mean acuity was 2.25 ± 0.64 logMAR units (20/3557) improving to 0.28 ± 0.42 logMAR (20/38) at final follow-up (p < 0.0001). Complications were similar in nature and frequency to the entire population in this subgroup. Supervised resident MSICS cataract surgery can result in excellent anatomic and visual outcomes. Appropriate wound construction is a frequently encountered difficulty, so particular attention should be directed to this step by both trainers and trainees.

Abstract
PURPOSE To evaluate the influence of a control group on the diagnostic accuracy of spectral-domain optical coherence tomography (SD-OCT) in early glaucoma. METHODS In a diagnostic, case-control study, 119 eyes of 60 normal subjects with no findings suspicious for glaucoma (control cohort 1); 76 eyes of 41 subjects referred by general ophthalmologists as glaucoma suspects based on optic disc morphology, but found by glaucoma experts to be normal but with physiological variations in their optic nerves (control cohort 2); and 65 eyes of 46 early-glaucoma patients (cases) underwent imaging of the optic nerve head (ONH), retinal nerve fiber layer (RNFL), and ganglion cell complex (GCC) by SD-OCT. RESULTS Areas under the receiver operating characteristic curves (AUC) of ONH parameters discriminating glaucomatous eyes from normal eyes of control cohort 2 were significantly lesser (P < 0.001) than those discriminating glaucomatous eyes from normal eyes of control cohort 1. AUCs of RNFL parameters discriminating glaucomatous eyes from normal eyes of control cohorts 2 and 1 were comparable. Although the AUCs of GCC thickness parameters were comparable, AUCs of GCC focal and global loss volume in control cohort 2 (0.684 and 0.671. respectively) were significantly less (P < 0.05) than in control cohort 1 (0.881 and 0.841, respectively). CONCLUSIONS The effectiveness of most SD-OCT parameters in detecting glaucoma significantly decreased when evaluated against a clinically relevant control group with suspicious-looking optic nerves compared with that against a control group consisting of normal subjects with no findings suspicious for glaucoma.

Abstract
Measles epidemics in West Africa cause a significant proportion of vaccine-preventable childhood mortality. Epidemics are strongly seasonal, but the drivers of these fluctuations are poorly understood, which limits the predictability of outbreaks and the dynamic response to immunization. We show that measles seasonality can be explained by spatiotemporal changes in population density, which we measure by quantifying anthropogenic light from satellite imagery. We find that measles transmission and population density are highly correlated for three cities in Niger. With dynamic epidemic models, we demonstrate that measures of population density are essential for predicting epidemic progression at the city level and improving intervention strategies. In addition to epidemiological applications, the ability to measure fine-scale changes in population density has implications for public health, crisis management, and economic development.

Abstract
Though largely controlled in developed countries, measles remains a major global public health issue. Regional and local transmission patterns are rooted in human mixing behaviour across spatial scales. Identifying spatial interactions that contribute to recurring epidemics helps define and predict outbreak patterns. Using spatially explicit reported cases from measles outbreaks in Niger, we explored how regional variations in movement and contact patterns relate to patterns of measles incidence. Because we expected to see lower rates of re-introductions in small, compared to large, populations, we measured the population-size corrected proportion of weeks with zero cases across districts to understand relative rates of measles re-introductions. We found that critical elements of spatial disease dynamics in Niger are agricultural seasonality, transnational contact clusters, and roads networks that facilitate host movement and connectivity. These results highlight the need to understand local patterns of seasonality, demographic characteristics, and spatial heterogeneities to inform vaccination policy.

Abstract
This open, prospective, randomised study was designed to evaluate the changes in intraocular pressure and haemodynamics after tracheal intubation using either the intubating laryngeal mask airway (ILMA) or direct laryngoscopy. Sixty adult patients, ASA physical status 1 or 2 with normal intraocular pressure were randomly allocated to one of the two techniques. Anaesthesia was induced with propofol followed by rocuronium. Tracheal intubation was performed using either the ILMA or Macintosh laryngoscope. Intraocular pressure, heart rate and blood pressure were measured immediately before and after tracheal intubation and then minutely for five minutes. In the laryngoscopy group there was a significant increase in intraocular pressure (from 7.2 ± 1.4 to 16.8 ± 5.3 mmHg, P <0.01), which did not return to pre-intubation levels within five minutes, and also in mean arterial pressure after tracheal intubation, which returned to baseline levels after five minutes. In the ILMA group there were no significant changes in intraocular pressure (from 7.6±1.8 to 10.4±2.8 mmHg, P >0.05) or mean arterial pressure after tracheal intubation. Time to successful intubation was longer with the ILMA, 56.8 ± 7.8 seconds, compared with the laryngoscopy group, 33±3.6 seconds (P <0.01). Mucosal trauma was more frequent with the ILMA (eight of 30) compared with the laryngoscopy group (three of 30) (P <0.01). The postoperative complications were comparable. In terms of minimising increases in intraocular pressure and blood pressure, we conclude that the ILMA has an advantage over direct laryngoscopy for tracheal intubation.
