With growing global advent of occupation and physical activity guidelines to prevent weight gain, anthropometric measures of height and weight have “stand tall” in checkmating an individual’s nutritional status through mass index (BMI). In recent times, studies have implicated abnormal weight gains in visual malfunctions. Current Study was therefore undertaken to examine in humans, specifically executive drivers, the effect of anthropometric changes (BMI, Weight and height) on visual capacities. Sixty-eight (68) executive drivers who were confirmed to be staff of the Delta State University, Abraka, Delta State, Nigeria were ethically recruited for the study. Subjects were then grouped into four (4 groups) based on their nutritional/BMI status. While Group 1 comprised of those with lower than normal BMI values (undernourished), Group 2 composed of subjects with normal nutritional (BMI) status (Control), with Groups 3 and 4 being over-nourished and obese participants respectively. For each sampled subject, selected visual function/capacities [Visual Acuity (VA), Ophthalmoscopy and Intra-Ocular Pressure (IOP)] were obtained and mapped against their respective BMI. Upon statistical analysis of data, study observed a higher mean value [ophthalmoscopy] in the early hours of morning than noon day. Intraocular pressure was also seen to be higher in the right than left eyes, increasing arithmetically at noon than morning. A statistically significant decrease (p < .05) in visual functions with increased BMI and day time was also noticed. Study therefore proved that IOP rises in Delsu executive drivers in the late noon day than early hours of the morning. We recommend a similar study for several other employees across government parastatals in the state.

AbstractThe use of an ileal segment is a standard method for urinary diversion after radical cystectomy. Unfortunately, utilization of this method can lead to numerous surgical and metabolic complications. This study aimed to assess the tissue-engineered artificial conduit for urinary diversion in a porcine model. Tissue-engineered tubular polypropylene mesh scaffolds were used for the right ureter incontinent urostomy model. Eighteen male pigs were divided into three equal groups: Group 1 (control ureterocutaneostomy), Group 2 (the right ureter-artificial conduit-skin anastomoses), and Group 3 (4 weeks before urostomy reconstruction, the artificial conduit was implanted between abdomen muscles). Follow-up was 6 months. Computed tomography, ultrasound examination, and pyelogram were used to confirm the patency of created diversions. Morphological and histological analyses were used to evaluate the tissue-engineered urinary diversion. All animals survived the experimental procedures and follow-up. The longest average patency was observed in the 3rd Group (15.8 weeks) compared to the 2nd Group (10 weeks) and the 1st Group (5.8 weeks). The implant’s remnants created a retroperitoneal post-inflammation tunnel confirmed by computed tomography and histological evaluation, which constitutes urostomy. The simultaneous urinary diversion using a tissue-engineered scaffold connected directly with the skin is inappropriate for clinical application.

The aim of this experimental study was to assess the spine development in growing rats following pinealectomy or partial sensorimotor cortical area damage. A total of 68 Wistar albino rats (Rattus norvegicus v. alba f. domestica) aged 3–4 weeks were divided into four groups. In group 1 (n = 22) pinealectomy was performed, in group 2 (n = 24) the sensorymotor cortical area 2 × 1 × 1 mm below the coronal suture was removed. Sham operation consisted of a craniotomy (n = 11) and a craniotomy with a durotomy (n = 11). All surgeries were performed from the left side. The rats were killed four months after surgery and radiography was then made. Scoliosis, C2-T7 lordosis and T7-S1 kyphosis were measured.The brains of rats after sensorimotor cortical area removal were isolated and investigated including histological examination (light microscope). Scoliosis of 9–14 degrees (mean value 10.8) was developed in five animals after pinealectomy; in rats after removal of the sensorimotor cortical area scoliosis of 10–24 degrees (mean value 15.9) was observed in eight animals. The scoliotic curves were non structural. Our results indicate the importance of cortical area damage, together with craniotomy and durotomy in the development of growing rat spine. These damages could cause a disorder of balance between smaller inhibitory and greater facilitating area of central nervous system, controlling the muscular tone and resulting in the development of increased lordosis and kyphosis and non structural scoliosis due to muscle imbalance. Thus the new hypothesis of scoliosis aetiology was introduced.

Objectives: To measure correlation and concordance between measured LDL cholesterol (mLDLc) and Friedewald’s calculated LDL cholesterol (cLDLc). To compare the mLDLc and cLDLc values for various anthropometric measures and biochemical indices including insulin resistance, nephropathy, glycated hemoglobin and triglycerides. Methods: Two hundred thirty two subjects were included in this cross-sectional analysis from Jan-2016 to July-2017 from a target population visiting PNS HAFEEZ hospital. Mean age of the subjects was 46.56(±11.95) years (n=232). These subjects underwent clinical evaluation including measurement of anthropometric measurements, biochemical testing for fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), lipid profile, urine albumin creatinine ratio (UACR), and insulin. Correlation and concordance between mLDLc and Friedewald’s cLDLc were measured. Finally, Comparison of risk evaluation for mLDLc and cLDLc between groups formulated based upon UACR (Based upon a cut off of 2.5 mg/g) and fasting triglycerides (Group-1 :< 1.0 mmol/L, Group-2: 1.0-1.99 mmol/L and Group-3 :> 1.99 mmol/) was carried out. Results: There was significant positive linear correlation between mLDLc and cLDLc [r=0.468, <0.001]. Kendall’s Coefficient of concordance between mLDLc and cLDLc was 0.055 (p<0.001). Differences evaluated by one way ANOVA analysis for mLDLc between various triglycerides groups were only significant between group-1 and group-2 [{Group-1:Mean=2.40, (2.19-2.61), n=43}, {Group-2:Mean=2.81, (2.69-2.92),n=136}, [{Group-3:Mean=2.59,(2.37-2.81), n=53}],(p=0.004) in comparison to cLDLc [{Group-1:Mean=2.63, (2.43-2.84), n=43}, {Group-2:Mean=2.85, (2.76-2.93), n=136}, [{Group-3:Mean=2.75, (2.60-2.90),n=53}]. Calculated method for LDLc showed higher UACR than mLDLc. (p=0.021) Conclusion: cLDLc over estimates LDL-cholesterol in comparison to mLDLc. The correlation between cLDLc and mLDLc was only moderate. However, cLDLc provided better degree of risk prediction for nephropathy and glycated hemoglobin than mLDLc. How to cite this:Khan SH, Niazi NK, Sobia F, Fazal N, Manzoor SM, Nadeem A.

Abstract Objective To determine the incidence of systemic to pulmonary collaterals (SPCs) in extremely low birth weight infants and to assess its clinical and hemodynamic significance beyond the neonatal period. Study Design Retrospective cohort study was conducted on 61 infants with echocardiogram performed at the time of discharge to determine the presence of SPC and to measure the right and left ventricular outputs and left atrium to aortic ratio. We compared two groups: small or no SPC (Group 1) to moderate or large SPC (Group 2) on demographics, clinical outcomes, and echocardiographic parameters. Results Sixty-one infants were included. The incidence of SPC was 57%; 21% of infants had moderate or large shunts and 31% had small SPC. Demographics, clinical outcomes, and echocardiographic parameters were not significantly different between small or no SPC and moderate to large SPC. Conclusion More than half of the infants had SPC. The size of the shunt did not affect the clinical outcomes nor the echocardiographic parameters measured. All infants had cardiac output above the normative mean.

We investigated if the temporal and ordinal structures of sequences can be represented and learned independently. In Experiment 1, subjects learned three rhythmic sequences of key presses with the right index finger: Combined consisted of nine key presses with a corresponding temporal structure of eight intervals; Temporal had the temporal structure of Combined but was performed on one key; Ordinal had the ordinal structure of Combined but an isochronous rhythm. Subjects were divided into two groups. Group 1 first learned Combined, then Temporal and Ordinal; Group 2 first learned Temporal and Ordinal, then Combined. Strong transfer effects were seen in both groups. In Group 1, having learned combined facilitated the learning of the temporal ( Temporal) or ordinal ( Ordinal) sequence alone; in Group 2, having learned Temporal and Ordinal facilitated the learning of Combined, where the two are combined. This supports that subjects had formed independent temporal and ordinal representations. In Experiment 2, we investigated if these can be learned independently. Subjects repeatedly reproduced sequences with fixed temporal and random ordinal structure; random temporal and fixed ordinal structure; and random temporal and ordinal structures. Temporal and ordinal learning was seen only in the first and second sequences, respectively. In summary, we provide evidence for the existence of independent systems for learning and representation of ordinal and temporal sequences and for implicit learning of temporal sequences. This may be important for fast learning and flexibility in motor control.

Background: Cystoid macular edema (CME) is the formation of fluid-filled cystoid spaces between the outer plexiform and inner nuclear layers of the retina. It may present as a complication of routine cataract surgery including phacoemulsification (PHACO) and small incision cataract surgery (SICS).Methods: An observational study of uncomplicated cataract surgery with assessment by ophthalmoscopy, slit Lamp, Snellen chart and OCT during pre- and post-operative period. 100 patients were selected by inclusion criteria and using convenient sampling technique and were divided into two groups of 50 each in PHACO and SICS groups.Results: During preoperative observation in SICS/group-1, mean value and SD of macular thickness was 223.38±12.61 and in PHACO/group-2 it was 224.14±12.69. Mean value, mean difference and p value of visual acuity in group 1 was 0.258, during 12 weeks 0.788 with mean difference -0.53 and p=0.000 and in group 2 it was 0.269, during 12 weeks 0.844 with mean difference -0.58 and p=0.000. Mean value, SD, mean difference and p value of macular thickness in SICS during 1 week was 238.28±12.29, during 12 weeks 227.04±12.58 with mean difference 11.24000 and p=0.000 and in PHACO mean value, SD, mean difference with p value during 1 week was 231.90±12.42, during 12 weeks was 225.02±11.74 with mean difference 6.88000 and p=0.000.Conclusions: A subclinical increase in post-operative macular thickness was recorded which returned nearly to baseline values during the 12 weeks follow up and did not affect visual outcome.

Background: The pain and limitation of shoulder function can disrupt daily activities of patients for months to years. Adhesive capsulitis is considered a self-limiting disease but the duration remains uncertain. The brunt of the disease is focussed on the inflamed joint capsule. On this basis, use of corticosteroid injection is justified. However, injection method is not conclusive. Objectives: To compare clinical benefits of intra-articular injection alone versus combined intra-articular and subacromial injections in management of adhesive capsulitis. Methods: Fifty-nine patients with diagnostic criteria for adhesive capsulitis were included in the study from March 2019 to September 2020. Patients were divided into two groups; patients who underwent intra-articular (IA) injection alone (Group 1) and those who received both intra-articular and sub-acromial (IA+SA) injection (Group 2). The injections were landmark guided. Patients were followed up at three, six, and 12 weeks. Pain was recorded using visual analogue scale (VAS) and subjective function using Constant-Murley score. Results: Twenty-eight patients were included in Group 1 (IA) and 31 in Group 2 (IA+SA). Thirty-six patients were female (18 each in Group 1 and Group 2) and 23 patients were male (Group 1 = 13; Group 2 = 10). In the twelfth week, VAS score was reduced in both the groups. On comparing the mean value of Constant-Murley score between the two groups there is significant difference in value recorded at the sixth and twelfth week. Conclusion: The IA+SA injection provides significant reduction in pain and better function in the short term over the IA injection.

Abstract We determined if meeting the 2018 physical activity guidelines was associated with better ambulatory function, health-related quality of life, and inflammation than failing to meet the guidelines in patients with peripheral artery disease and claudication. Secondly, we determined the optimal number of total daily steps that are needed to meet the physical activity guidelines. Five hundred seventy-two patients were assessed on their daily ambulatory activity for one week with a step activity monitor, and were grouped according to whether they achieved less than 150 minutes of moderate intensity physical activity per week (Group 1=Do Not Meet Guidelines; n=397), or whether they were above this threshold (Group 2=Meet Guidelines; n=175). Treadmill peak walking time (mean±SD) was significantly higher (p&lt;0.001) in Group 2 (709±359 sec) than in Group 1 (427±281 sec). The health-related quality of life score for physical function was significantly higher (p&lt;0.001) in Group 2 (61±22%) than in Group 1 (44±21%). High sensitivity C-reactive protein was significantly lower (p&lt;0.001) in Group 2 (3.6±4.5 mg/L) than in Group 1 (5.9±6.1 mg/L). Finally, 7,675 daily steps was the optimal threshold associated with meeting the physical activity guidelines, with a sensitivity of 82.9% and a specificity of 88.4%. In conclusion, patients with claudication who meet the 2018 physical activity guidelines for US adults had better ambulation, HRQoL, and inflammation outcomes than those who failed to meet the guidelines. From a practical standpoint, patients with claudication best achieved the physical activity guidelines by taking a total of 7,675 daily steps.

ABSTRACT Retention in mandibular dentures has always been a challenge for the treating dentist. Denture adhesives are known to improve the adhesive bond between the denture and the underlying tissues. However, denture adhesives still remain unexplored and not much is known about the efficacy of these materials in mandibular dentures especially in patients with poor foundations. The present study was carried out to compare the efficacy of different commercially available denture adhesives in relation to their retentive ability in patients with good well formed mandibular ridges and in patients with resorbed and flat mandibular ridges. Seventy edentulous patients, age range between 50 to 70 years, were selected. The patients were divided into 2 groups; group 1 comprised of 35 patients with good well formed mandibular ridges and group 2 consisted of 35 patients having low well rounded mandibular ridges. The adhesion and cohesion that developed between the dentures and the underlying tissues when the various materials were interposed between them was evaluated with the help of a test apparatus in newtons. Mean value of retention in denture without adhesive was 9.93 N and 24.53 N in resorbed and well formed ridges respectively. Use of denture adhesive materials led to a higher value of retention as opposed to when the dentures were used without adhesives. This was true for patients with good well formed mandibular ridges as well as for patients with poor foundations. Among the various denture adhesive powders tested, Fittydent showed better results, i.e. 29.56 and 33.05 in resorbed and well-formed ridges respectively as opposed to fixon which showed values of 16.47 and 27.70 respectively.

Objectives: This study aimed to assess the microleakage of Pedo Jacket crowns compared to stainless steel crowns (SSCs) cemented with different luting cements. Materials and Methods: In this in-vitro experimental study, 80 primary molars were randomly divided into four groups of 20 each. Groups 1 and 2 were subjected to standard tooth preparation for SSC. Crowns in group 1 were cemented with glass ionomer (GI), and crowns in group 2 were cemented with a resin-modified glass ionomer (RMGI) cement. In groups 3 and 4, minimal tooth preparation was performed for Pedo Jacket crowns, and the crowns were cemented with RMGI and Panavia resin cement, respectively. Microleakage was measured at mesial and distal surfaces in micrometers (µm), and the mean value for each tooth was calculated. One-way analysis of variance (ANOVA) was applied to compare the microleakage of the four groups. Results: Group 3 (Pedo Jacket cemented with RMGI) showed the highest microleakage (1523.83±250.32 µm) with significant differences with the remaining three groups (P<0.001). Microleakage in group 4 (Pedo Jacket cemented with Panavia) was significantly lower than that in the other three groups (301.25±219.53 µm, P<0.001). Groups 1 (SSCs cemented with GI) and 2 (SSCs cemented with RMGI) were not significantly different in terms of microleakage (P=0.49) although group 1 showed slightly higher microleakage than group 2 (598.43±260.85 µm versus 500.25±124.74 µm). Conclusions: Pedo Jacket crowns can serve as an acceptable esthetic alternative to SSCs if cemented with resin cements.
