There is currently limited information on the benefits of increasing the concentration of Trichanthera gigantea leaves in pelleted diets offered to lambs reared under tropical conditions in the Caribbean. Twelve crossbred Barbados Blackbelly rams aged 5 months were used to determine the effects of increasing the concentrations of T. gigantea in pelleted diets, on the nutritive value and intake of grass forage plus pellets offered to lambs. Animals were randomly assigned to a basic diet (4 kg) of chopped Cenchrus purpureus plus 1 of 6 pelleted diets (500 g) comprised of either 100% intact commercial pellets or a pelleted mixture of ground commercial pellets and ground (dry fallen) T. gigantea leaf in the following ratios (T. gigantea leaves:ground commercial pellets): 20:80 (T20); 40:60 (T40); 60:40 (T60); 80:20 (T80); and 100:0 (T100). Total intakes of forage and pellets (TPI) were measured at the end of each day during a period of 7 days, and the average daily nutrient intakes of the different treatment diets were calculated. Overall, there was no significant difference in the intakes of pellets containing 0 to 80% T. gigantea leaves (P>0.05) but intakes of pellets comprising 100% T. gigantea leaves were significantly lower (P<0.0001). Both CP and soluble protein intakes declined progressively as the percentage of T. gigantea leaves in the pellets increased. While level of T. gigantea leaves in pellets fed to lambs did not generally affect total intakes of pellets, grass, or grass+pellets, animal performance on these various rations cannot be assumed to be similar until longer-term feeding studies have been performed, as reduced protein and energy concentrations in the pellets could significantly lower weight gains as level of leaf in the pellets increased.

Laparoscopic Hemicolectomy

Összefoglaló. Bevezetés: A laparoszkópia térhódítása a jobb oldali colon műtéteknél is nyilvánvaló. Ma legtöbb helyen a laparoszkóposan asszisztált jobb oldali hemikolektómia extrakorporális anasztomózissal a gold standard. A morbiditás randomizált vizsgálatok alapján még 30% körüli. A technikai fejlődés lehetővé tette az intrakorporális anasztomózist. Célkitűzés: Retrospektív módon elemezni rosszindulatú jobb oldali vastagbéldaganat miatt végzett laparoszkópos hemikolektómiák rövid távú eredményeit a két módszer összehasonlításával. Eredmények: 2018. 01. 01. – 2019. 12. 31. között 184 jobb oldali hemikolektómiát végeztünk, ezek közül 122 történt malignus betegség miatt. 51 esetben nyitott és 71 esetben laparoszkópos műtét történt. 37 férfi (átlagéletkor: 70,59 év) és 34 nő (átlagéletkor: 72,14 év) volt. 50 esetben extrakorporális (EA) és 21 esetben pedig intrakorporális anasztomózist (IA) végeztünk. Az EA csoportban 18, míg az IA csoportban 3 szövődmény alakult ki 30 napon belül (p = 0,067). Az EA csoportból 3, az IA csoportból 1 beteget veszítettünk el 30 napon belül (p = 0,66). Az átlagos ápolási idő az EA csoportban 9,48 (5–32) nap, míg az IA csoportban 6,52 (4–19) nap volt (p = 0,001) a szövődményes esetekkel együtt. A szövődményes esetek nélkül az EA csoportban 6,35 (5–10) nap, az IA csoportban pedig 5,55 (4–8) napnak bizonyult (p = 0,09). A műtéti idő pedig az EA csoportban 147 (90–240) perc, az IA csoportban pedig 146,47 (90–265) perc volt (p = 0,11). Konklúzió: Az irodalommal összhangban azt találtuk, hogy IA esetén kevesebb a szövődmény, ezzel is összefüggésben rövidebb az átlagos ápolási idő, és a műtéti időt tekintve nincs szignifikáns különbség. Ezeket figyelembe véve az intrakorporális anasztomózis javasolható jobb oldali laparoszkópos hemikolektómia esetén. Summary. Introduction: Laparoscopy became evident for right-sided colon surgery too. Today the laparoscopic-assisted right-hemicolectomy is the gold standard with extracorporeal anastomosis. Morbidity according to randomized trials is still approximately 30%. The development of the surgical technique resulted in the creation of intracorporeal anastomosis. Our aim was to compare the short-term results of the two methods. Aim: To analyse the short-term results of right-sided hemicolectomy that were performed due to malignant tumours with the comparison of the two methods. Results: A cohort of 184 right-sided hemicolectomy were performed from 01.01.2018 to 31.12.2019 from which 122 were operated on because of a malignant disease. 51 open and 71 laparoscopic operations were performed. The average age of 37 men and 34 women were 70.59 and 72.14 years, respectively. 50 patients underwent extracorporeal (EA) anastomosis and 21 intracorporeal (IA) anastomosis. Within 30 days the number of complications were 18 in the EA group and 3 in the IA group (p = 0.067). 3 from the EA group and 1 from IA group died within 30 days (p = 0.66). The average length of stay were 9.48 days in the EA group and 6.52 days in the IA group together with the complicated cases (p = 0.001) while 6.35 days and 5.55 days without the complicated cases (p = 0.09). The average duration of operation was 147 minutes in the EA and 146.47 minutes in the IA group (p = 0.11). Conclusion: We found concordance with the literature that there are fewer complications in case of IA which might be related to shorter length of stay. There is no significant difference between the surgical times. Bearing these facts in mind, IA might be suggested for right- sided laparoscopic hemicolectomy.

Objective: To study the effect of short-term use of oral contraceptive pills on intra-ocular pressures of women of childbearing age.   Methods: It was a comparative observational study, conducted at Arif memorial teaching hospital and Allied hospital Faisalabad for a period of six months. Hundred female subjects were divided into two groups of 50 each. Group A, included females, who had been taking oral contraceptive pills (OCP) for more than 6 months and less than 36 months. Group B, included 50 age-matched controls, who had never used OCP. Ophthalmic and systemic history was taken. Careful Slit lamp examination was performed and intraocular pressures (IOP) were measured using Goldman Applanation tonometer. Fundus examination was done to rule out any posterior segment disease. After collection of data, we analyzed and compared the intra ocular pressures between the two groups by using ANOVA in SPSS version 21.   Results: Average duration of using OCP was 14.9 months. There was no significant difference of Cup to Disc ratios between the two groups (p= 0.109). However, significant difference was noted between the IOP of OCP group and controls. (p=0.000). Conclusion: OCP significantly increase IOP even when used for short time period.

Purpose: The purpose of this study was to investigate T1 relaxation time of the human Achilles tendon, to test its short-term repeatability as well as the minimal detectable change, and to assess the extent that correlate with clinical symptoms. Methods: Twenty asymptomatic volunteers and eighteen patients with clinically and sonographically confirmed tendinopathy were scanned for ankle using a 3 Tesla (T) MR scanner. T1 maps were calculated from a variable flip angle gradient echo Ultra-short echo time sequence (VFA-GE UTE) and inversion recovery spin echo sequence (IR-SE) using a self-developed matlab algorithm in three regions of interest of Achilles Tendon (AT). Signal to Noise Ratio (SNR) between the two sequences was evaluated. INTRA-class Correlation Coefficient (ICC), Coefficient of Variation (CV) and the Least Significant Change (LSC) were calculated, to test short-term repeatability of T1. Subjects were assessed by the VISA-A clinical score. P values less than 0.005 were considered statistically significant. Results: Mean T1 values were 427.09 ± 53.37 ms and 528.70 ± 103.50 ms using IR-SE sequence and 575.43 ± 110.60 ms and 875.81 ± 425.77 ms with VFA-GE UTE sequence in the whole AT for volunteers and patients, respectively. : T1 values showed a significant difference between volunteers and patients (P=0.001). Regional variation of T1 in healthy and tendinopathic AT were greater for VFA-GE UTE sequence than for IR-SE sequence. VFA-GE UTE sequence showed clearly higher SNR compared to IR-SE sequence. Short-term repeatability of T1 values for volunteers showed an LSC of 22% and 14% for IR-SE sequence and VFA-GE UTE sequence, respectively. For patients, LSC was 14% and 5% for IR-SE sequence and VFA-GE UTE sequence, respectively. There was no correlation between T1 and VISA-A clinical score (p>0.005). Conclusion: VFA-GE UTE sequence used for T1 mapping calculation demonstrated short acquisition time and clearly high SNR. Results revealed that T1 relaxation time can be used as a biomarker to differentiate between healthy and pathologic Achilles tendon. However, T1 showed no correlation with the VISA-A clinical score.

Objective: The objective of this review was to evaluate the effect of non-thermal atmospheric plasma (NTAP) on adhesives resin–dentin micro-tensile bond strength (μTBS) in previously published studies. Methods: Electronic search was conducted using the Medline, Cochrane library, and Scopus databases. The included studies were laboratory studies that investigated the effect of NTAP on adhesives μTBS to coronal dentin. Studies that evaluated the effect of NTAP on bond strength to indirect substrates, enamel or root dentin, were excluded. The methodological quality of included studies was assessed. Results: Thirteen studies were included in this systematic review. All the included studies were considered to have a medium risk of bias. NTAP significantly improved μTBS at 24 h or after short-term aging in five studies (38.5%) and both immediate and after long-term aging in 5 studies (38.5%). In two studies (15.4%), NTAP resulted in a short-term material-dependent effect that was not stable after long-term aging. Interestingly, in one study (7.7%), NTAP had a positive effect only in the etch-and-rinse (ER) mode after long-term aging. Conclusion: Within the limitations of this systematic review, NTAP application could enhance resin–dentin μTBS of ER adhesives or universal adhesives (UAs) applied in the ER mode. In the ER mode, the rewetting step after NTAP seems to be unnecessary. Because of the limited information currently available in the literature, further studies are required to evaluate the effect of the NTAP application on self-etch (SE) adhesives or UAs applied in the SE mode.

Background: Undernutrition among schoolchildren is a prevalent public health problem which may be due to inadequate energy and nutrient intakes associated with low dietary diversity. Objective: This study assessed dietary diversity scores (DDS), energy and nutrient intakes of schoolchildren (6-15 years), and risks factors of DDS and determined if energy and nutrient intakes were dependent on dietary diversity. Methods: The study involved a 2-stage random sampling of 90 schoolchildren. Dietary diversity and nutrient intake data were obtained through a 3-day weighed food intake. Analysis of variance, t test, and χ2 with Cochran-Mantel-Haenszel test were used to determine relationships among and between variables; P < .05 was reported as significant. Results: Few (22.2%) had high DDS with no significant difference ( P > .05) between age groups and sex. Children from male headed households were more likely to have medium DDS (odds ratio [OR] = 3.231; 95% confidence interval [CI] = 1.037-10.070) than those from female headed households ( P < .05). Low nutrient intakes were observed among 85.6% for niacin, 76.7% for calcium, 72.2% for riboflavin, 54.4% for protein, 32.2% for thiamine, and 15.6% for vitamin C. Among boys, prevalence of inadequate riboflavin intake was significantly ( P < .05) higher among 6- to 9-year-olds. Among girls, prevalence of inadequate vitamin A intake was significantly ( P < .01) higher among 10 to 15-year-olds. Children with adequate intakes of iron (OR = 0.744, 95% CI = 0.653-0.847) and thiamine (OR = 5.651, 95% CI = 1.214-26.310) were more likely to have high DDS. Conclusion: The schoolchildren had low energy and nutrient intakes. Iron and thiamine, intakes were dependent on DDS.

The effects of salt and osmotic stresses on the germination processes in seeds of the perennial halophyte species Atriplex halimus L. were compared using iso-osmotic concentrations of NaCl and mannitol. The lowest stress intensity delayed germination, while higher doses of NaCl and mannitol reduced final germination percentages. No significant difference occurred between the effects of these solutes on germination percentages or seedling dry weights. At an external osmotic potential of –0.7 MPa, however, the water content of mannitol-treated seedlings was reduced compared to that of seedlings that developed from NaCl-exposed seeds. The K, Mg, and Pi content decreased in seedlings that developed from mannitol-treated seeds while calcium concentration was strongly reduced in those arising from NaCl-treated seeds. Inhibited seeds were able to germinate at levels similar to those of the control after rinsing in deionized water and imbibition in control conditions. Seedlings produced from NaCl pre-treated seeds had a lower Ca and a higher Na content than control seedlings. The effect of salinity on the germination phase of development is mainly due to its osmotic component, and inhibition of germination is reversible. Both salt and osmotic stresses may have an impact on the mobilization of minerals from the seeds to the young seedling, but this effect does not have any consequence on growth processes analysed on a short-term basis.Key words: Atriplex halimus, halophyte, osmotic stress, recovery of seed germination, salinity.

Although the manipulation of exercise and dietary intake to achieve successful weight loss has been extensively studied, it is unclear how the time of day that exercise is performed may affect subsequent energy intake. The purpose of the current study was to investigate the effect of an acute bout of exercise performed in the morning compared with an equivalent bout of exercise performed in the afternoon on short-term energy intake. Nine healthy male participants completed 3 trials: morning exercise (AM), afternoon exercise (PM), or control (no exercise; CON) in a randomized counterbalanced design. Exercise consisted of 45 min of treadmill running at 75% VO2peak. Energy intake was assessed over a 26-hr period with the participants eating ad libitum from a standard assortment of food items of known quantity and composition. There was no significant difference in overall energy intake (M ± SD; CON 23,505 ± 6,938 kJ, AM 24,957 ± 5,607 kJ, PM 24,560 ± 5,988 kJ; p = .590) or macronutrient preferences during the 26-hr period examined between trials. Likewise, no differences in energy intake or macronutrient preferences were observed at any of the specific individual meal periods examined (i.e., breakfast, lunch, dinner) between trials. These results suggest that the time of day that exercise is performed does not significantly affect short-term energy intake in healthy men.

Abstract Purpose To evaluate safety and efficacy of a mesh reinforcement following stoma reversal to prevent stoma site incisional hernia (SSIH) and differences across the prostheses used. Methods A systematic search of PubMed/MEDLINE, EMBASE, SCOPUS and Cochrane databases was conducted to identify comparative studies until September 2020. A meta-analysis of postoperative outcomes and a network meta-analysis for a multiple comparison of the prostheses with each other were performed. Results Seven studies were included in the analysis (78.4% ileostomy and 21.6% colostomy) with a total of 1716 patients with (n = 684) or without (n = 1032) mesh. Mesh placement was associated with lower risk of SSIH (7.8%vs18.1%, OR0.266,95% CI 0.123–0.577, p < 0.001) than no mesh procedures but also with a longer operative time (SMD 0.941, 95% CI 0.462–1.421, p < 0.001). There was no statistically significant difference in terms of Surgical Site infection (11.5% vs 11.1%, OR 1.074, 95% CI 0.78–1.48, p = 0.66), seroma formation (4.4% vs 7.1%, OR 1.052, 95% CI 0.64–1.73, p = 0.84), anastomotic leakage (3.7% vs 2.7%, OR 1.598, 95% CI 0.846–3.019, p = 0.149) and length of stay (SMD − 0.579,95% CI − 1.261 to 0.102, p = 0.096) between mesh and no mesh groups. Use of prosthesis was associated with a significant lower need for a reoperation than no mesh group (8.1% vs 12.1%, OR 0.332, 95% CI 0.119–0.930, p = 0.036). Incidence of seroma is lower with biologic than polypropylene meshes but they showed a trend towards poor results compared with polypropylene or biosynthetic meshes. Conclusion Despite longer operative time, mesh prophylactic reinforcement at the site of stoma seems a safe and effective procedure with lower incidence of SSIH, need for reoperation and comparable short-term outcomes than standard closure technique. A significant superiority of a specific mesh type was not identified.

The optimal method of fixation for primary total hip replacements (THR), particularly fixation with or without the use of cement is still controversial. In a systematic review and metaanalysis of all randomized controlled trials comparing cemented versus uncemented THRS available in the published literature, we found that there is no significant difference between cemented and uncemented THRs in terms of implant survival as measured by the revision rate. Better short-term clinical outcome, particularly an improved pain score can be obtained with cemented fixation. However, the results are unclear for the long-term clinical and functional outcome between the two groups. No difference was evident in the mortality and the post operative complication rate. On the other hand, the radiographic findings were variable and do not seem to correlate with clinical findings as differences in the surgical technique and prosthesis design might be associated with the incidence of osteolysis. We concluded in our review that cemented THR is similar if not superior to uncemented THR, and provides better short term clinical outcomes. Further research, improved methodology and longer follow up are necessary to better define specific subgroups of patients in whom the relative benefits of cemented and uncemented implant fixation can be clearly demonstrated.

AbstractThe qualitative and quantitative parameters of temporal distribution ofCucullanus tripapillatusandCucullanus chrysophrydesin the intestine ofOrthopristis ruberin the Caribbean Sea on the north of Margarita Island, Venezuela were analysed. A total of 540 fish were collected at random from the catch of commercial trawlers during 1982–83 and 1992–93. Both species ofCucullanuswere found throughout the year; prevalence and mean intensity ofC. tripapillatuswere higher than that ofC. chrysophrydes. A significant difference was found in infection between the two years of sampling. Female worms were more abundant than male in both years. Both species exhibited pronounced prevalence and maturity in September and March of each year, indicating seasonality. The patterns of occurrence of the two species ofCucullanusinO. ruberdid not change in the 10-year interval but the host size and number of parasites declined, which may be due to over-exploitation of definitive fish hosts.
