Effects of organic selenium supplemented diet on growth performance and antioxidant response in Cirrhinus mrigala

The present study was conducted to evaluate the …effect of dietary selenium on growth performance and antioxidant enzymes activity in Cirrhinus mrigala for a period of 45 days. Four numbers of experimental diets were prepared, Tc for Control (0 mg organic selenium/kg of diet), T1 (2.5 mg organic selenium/kg of diet), T2 (5.0 mg organic selenium/kg of diet) and T3 (10 mg organic selenium/kg of diet). The water quality parameters (temperature, DO, pH, conductivity, hardness, ammonia, nitrate and nitrite) were found to be insignificant (p > .05) among all the treatments. Superoxidase dismutase (SOD) was found to be significantly highest in T2 (6.10 ± 0.07) when compared with the other treatments. Similarly, catalase (CAT) activity in T1 (13.21 ± 0.13) was significantly (p < .05) different with that of Control, T2 and T3. Present study also revealed that 2.5mg organic selenium/kg supplemented diet (T1) showed highest results in net weight gain (15.55 ± 1.36 g), net weight gain percentage (185.88 ± 8.98%) and SGR (2.35 ± 0.06 g) compared with other experimental diet.

POOR POSTNATAL WEIGHT GAIN AS A PREDICTOR OF RETINOPATHY OF PREMATURITY.

SUMMARYThe purpose of this study was to re-evaluate cut-off values used in screening for retinopathy of prematurity (ROP) in Croatia and to propose postnatal weight gain as an additional criterion, based on the Colorado Retinopathy of Prematurity prediction model. Medical records of 267 premature infants from the Zagreb University Hospital Centre that underwent ROP screening between January 2009 and December 2010 were reviewed retrospectively. Collected data included gestational age, birth weight, sex, weekly weight measurements and fundus examination records. Results showed the cut-off values of gestational age (GA) and birth weight (BW) used in Croatia to be appropriate and postnatal weight gain in the first 28 days could be used as an additional criterion on screening in the following way: net weight gain in the first 28 days of ≤932 g for prediction of any form of ROP and of ≤660 g for prediction of severe ROP should be added to the existing criteria of GA (≤32 weeks) and/or BW (≤1500 g). Infants with a non-physiological postnatal weight gain are exception. This is the first Croatian study to propose postnatal weight gain as an additional criterion on ROP screening and requires further validation on a larger sample of Croatian infants.

Weight Changes Post-Phentermine Use

Purpose: Evaluate weight maintenance in subjects who lost weight while taking phentermine (PTM). Methods: This study was conducted by utilizing a validated survey to collect self-reported data about weight changes post-PTM use. The survey was sent to 19,986 email addresses of current and former patients of a PTM-based outpatient clinic, located in Chicago, IL; 546 participants completed the survey. Results were analyzed using a variety of techniques. Results: At the time of the survey, 42% of responders maintained all the weight lost while on PTM, and 25.2% had maintained a weight loss of at least 10% of their body weight. The average weight lost and maintained at the time of the survey was 3.75% ± 13.8% of body weight or 8.74 lbs ± 27.45 lbs. Nineteen responders had no net weight change. Fifty-nine responders reported a net weight gain, ranging from 2 to 70 lbs with a mean net weight gain of 16.07 lbs ± 13.87 lbs. The duration of time since discontinuing PTM use had a significant correlation with weight maintenance: r = 0.340, p value = .000. There was no significant correlation between duration of time using PTM and weight maintenance. No correlations were identified between education, income, or ethnicity and weight maintenance. A correlation was identified between weight maintenance and current exercise level: r = 0.218, p value = .000. Conclusions: Although more research is needed, with the results of this study, the investigators suggest that post-PTM use, weight regain is not significantly higher than weight regain through other weight loss programs. In order to achieve long-term weight loss maintenance, it may behoove patients to receive professional guidance about behavior modifications to maintain weight lost, particularly related to exercise and dietary changes. The investigators of this study suggest greater emphasis on behavior modification in patients taking PTM is indicated.

Effects of stocking density on growth performance and profitability of Labeo bata fry reared in earthen ponds

The aim of this study was to evaluate the effects of stocking density on growth, production and profitability of farming Labeo bata fry in earthen rearing ponds for a period of 60 days. Labeo bata, fry (mean initial length, 3.42 ± 0.07cm and weight, 1.02 ± 0.06 g) were stocked at 750, 1000 and 1250 decimal-1 in treatment-1(T1), treatment-2 (T2) and treatment-3 (T3) respectively, each with two replicates. Growth performance in term of final length and weight, net length and weight gain, specific growth rate were significantly higher (P<0.05) in T1 than those of T2 and T3. Feed Conversion Ratio followed the opposite trends as specific growth rate. Production in terms of weight was found to be higher in T2 followed by T3 and T1, because of higher stocking density compare to T1 and higher weight gain in comparison to fish reared under T3 as well as insignificance variation in survival rate between T1 and T2. Consistently higher net benefits were found from treatment T2, which could be recommended to adopt. Moreover, further studies are also required to find out suitable culture technique that could enhance the production experimenting with different feeding frequencies as well as by manipulating culture systems.

Immunostimulatory and antifertility effects of neem (Azadirachta indica) leaf extract on common carp (Cyprinus carpio Linnaeu)

180-day feeding trial was conducted on the growth performance, feeding efficacy, immunological parameters and gonadal reproductive parameters of common carp, Cyprinus carpio fed with neem (Azadirachta indica) leaf extract (NLE) incorporated at different levels (0, 0.25, 0.5, 1.0, 1.5 and 2.0 g kg-1 feed) in rice bran and mustard meal (1:1 ratio) basal diet. The study revealed highest Net Weight Gain (NWG) in fish fed on NE 1.0 g kg. Results showed that the good growth response was obtained in fish fed with the NLE 1.0 g kg-1 feed and least in fish fed only on basal diet (without NLE). Whereas, higher gonado-somatic index (GSI), relative fecundity and ova diameter values were obtained from fish fed on basal diet while the least were observed from fish fed only on basal diet, while the least value was fish fed with NLE 1.0 g kg-1 feed. Fish fed with NLE 1.0 g kg-1 feed also showed significantly (p<0.05) enhanced phagocytic activity ratio, Phagocytic index, NBT activity, CAT, SOD, GPx and GR responses in comparison with fish fed only on basal diet, where as LPO is significantly decreased on being fed with NLE up to 1g kg-1 feed. The study indicated that incorporation of NLE in feed improved growth, delayed female gonadal maturation and could be used as a potential immunostimulant and to control the prolificbreeding of C. carpio in aquaculture.

Fluid retention after shoulder arthroscopy: gravity flow vs. automated pump—a prospective randomized study

Soft tissue fluid retention due to irrigation is relatively common after shoulder arthroscopy. The objective of this study was to compare fluid retention of 2 irrigation systems of shoulder arthroscopy: gravity flow irrigation and automated pump. Patients undergoing shoulder arthroscopy were enrolled prospectively and randomized into 2 groups using gravity flow system (GFS) or automated pump system (APS) for irrigation. Net weight gain was the primary outcome measurement to determine periarticular fluid retention. Change in deltoid diameter and postoperative pain were also compared. Forty-two patients were included in the study. There were no statistically significant differences between the GFS and APS groups regarding demographics, surgical procedures, duration of surgery, or the amount of irrigation fluid used. The APS group had greater weight gain per hour (1.46 ± 0.36 kg/hvs. 1.1 ± 0.38 kg/h) than the GFS group. A strong correlation was found between the amount of fluid used and the weight gain in both the GFS and APS groups. But a strong correlation between duration of surgery and weight gain was found in the APS group only. The APS group also had a greater mean deltoid diameter increase (3.33 ± 1.56 cm vs. 2.1 ± 1.44 cm) and a higher postoperative first-hour visual analog pain scale score (5.81 ± 2 vs. 3.62 ± 1.6). APS causes more fluid retention than GFS in shoulder arthroscopy when used for equal durationin similar procedures. Use of APS, prolongation of surgery, and increased amounts of irrigation fluid increase weight gain as a result of fluid retention.

Elucidating Under-Studied Aspects of the Link Between Obesity and Multiple Myeloma: Weight Pattern, Body Shape Trajectory, and Body Fat Distribution.

BackgroundAlthough obesity is an established modifiable risk factor for multiple myeloma (MM), several nuanced aspects of its relation to MM remain unelucidated, limiting public health and prevention messages.MethodsWe analyzed prospective data from the Nurses’ Health Study and Health Professionals Follow-Up Study to examine MM risk associated with 20-year weight patterns in adulthood, body shape trajectory from ages 5 to 60 years, and body fat distribution. For each aforementioned risk factor, we report hazard ratios (HRs) and 95% confidence intervals (CIs) for incident MM from multivariable Cox proportional-hazards models.ResultsWe documented 582 incident MM cases during 4 280 712 person-years of follow-up. Persons who exhibited extreme weight cycling, for example, those with net weight gain and one or more episodes of intentional loss of at least 20 pounds or whose cumulative intentional weight loss exceeded net weight loss with at least one episode of intentional loss of 20 pounds or more had an increased MM risk compared with individuals who maintained their weight (HR = 1.71, 95% CI = 1.05 to 2.80); the association was statistically nonsignificant after adjustment for body mass index. We identified four body shape trajectories: lean-stable, lean-increase, medium-stable, and medium-increase. MM risk was higher in the medium-increase group than in the lean-stable group (HR = 1.62, 95% CI = 1.22 to 2.14). Additionally, MM risk increased with increasing hip circumference (HR per 1-inch increase: 1.03, 95% CI = 1.01 to 1.06) but was not associated with other body fat distribution measures.ConclusionsMaintaining a lean and stable weight throughout life may provide the strongest benefit in terms of MM prevention.

“How Much Does My Implant Weigh?”: Addressing Patient Concern about Weight Gain after Total Hip Arthroplasty

AbstractA common concern for patients undergoing joint replacement is that the implant will increase their body weight. In an effort to determine if in fact the joint implant is heavier than the bone removed during surgery, the authors conducted a 3-year review from 11/2014 to 11/2017 of 339 patients who underwent total hip arthroplasty (THA) procedures performed by a single surgeon. In the 339 patients, the bone and tissue removed from the patient was weighed. Using the known weights of each component (cup, head, and stem), the authors calculated the total mass of the hip prosthetic implant. Using deidentified patient data, they reviewed only the weight of bone and tissue removed and the calculated weight of the implant placed in each THA performed by the single surgeon. They subtracted the mass of the bone and tissue removed during surgery from the total mass of the hip implant to determine the net weight differential in the patient following surgery and calculated an average net weight gain of 124.84 g in the 339 patients who underwent THA. This weight gain of 124.84 g is equivalent to 0.275 lbs. Previous studies have only looked at weight gain or loss following total joint replacement with respect to natural weight loss/gain that may be associated with improved mobility following surgery. This is the first study to measure the actual quantifiable net weight differential due to the joint replacement itself. The authors concluded that no appreciable weight gain following THA can be attributed to the weight of the implant.

The Alexandria retinopathy of prematurity model (Alex-ROP): postnatal weight gain screening algorithm application in a developing country.

To suggest a novel retinopathy of prematurity (ROP) screening model in developing countries incorporating postnatal weight gain ratios (PWGR) to traditional parameters to maintain sensitivity and improve specificity in detecting ROP. Analysis of weekly PWGR of infants from one tertiary referral center during six months to determine the age at which the PWGR with the highest predictability for ROP development which was referred to as the postnatal net weight gain ratio (NWGR). NWGR was added to conventional criteria to describe a new model (The Alex-ROP model). Of 560 infants were included. NWGR 28d after birth was the most predictive factor for the development of ROP. A new model Alex-ROP recommending screening infants with gestational age (GA) ≤33wk or birth weight ≤1500 g and NWGR at 28d after birth <0.3 was suggested. A second screening model referred to as High-grade Alex-ROP (Hg Alex-ROP) model to detect worse grade ROP (Both type 1 and type 2) recommending a cutoff point of NWGR <0.15 between birth and 28th day. Both Alex-ROP and Hg Alex-ROP models are easy to apply to improve the specificity of ROP screening in developing countries while maintaining high sensitivity.

Effect of Feed Restriction on Broiler Chicks Prior to Slaughter

The present study was conducted to study the effect of feed restriction prior to slaughter on carcass weight of male broiler chicks from 32 to 40 days of age. A total number of 180 (Pure line) male broiler chicks were taken randomly, labeled and divided into six groups. At 32 days of age, the experimental groups were put under the experimental feeding program. Group A fed ad libitum (control) while group B and C fed 120, 60 gm/bird/day for eight days, respectively. Group D and E fed 120, 60 gm/bird/day for four days respectively, followed by zero feeding for an extra 4 days. Group F deprived of food during the whole experimental period (8 days). The experimental diet was formulated to be approximately iso caloric-iso nitrogenous containing sorghum, groundnut cake, broiler concentrate, calcium, salt, lysine, methionine, and premix. The parameters taken were live body weight, feed intake, mortality, carcass, and non-carcass values. The effect of feed restriction program on male broiler chicks was not significant during the period from 32 to 34 days of age for parameters final live body weight, carcass weight, and dressing percentage, but net weight (gain or loss) was affected by feed restriction program and showed a significant difference (P 0.05) between experimental groups for dressing percentage during period from32 to 36 days of age. At the period from 32 to 38 days and the period from 32 to 40 days of age, all parameters were significantly affected by feed restriction program. It was concluded that carcass weight of broiler chickens can be controlled using different options of feed restriction programs according to the need of the market and the producer situation with special consideration to the economic return.

A16196 Pre-pregnancy body mass index and weight gain related pregnancy hypertension

Objectives: To study the relationship between pre-pregnancy body mass index (BMI) and weight gain during pregnancy with pregnancy. Methods: We included 2143 mothers who beard baby during December 2013–2014 November in Gansu Province maternal and child health hospital. Weight before pregnancy and weight after delivery were collected and we calculated BMI and net gestational weight gain. Gestational hypertension and gestational age and birth weight were collected. We used multivariate linear or logistic models to study the association between BMI, and pregnancy hypertension. Results: Of all 2143 pregnant women screened, 60 patients with pregnancy-induced hypertension were screened and the detection rate of pregnancy-induced hypertension was 2.7%. Univariate analysis showed that the weight gain during pregnancy was higher than normal, and the two factors of pre-pregnancy BMI were related to the occurrence of hypertensive pregnancy. Multivariate logistic regression analysis showed that the weight gain during pregnancy was high in normal women. Pre-pregnancy BMI is a risk factor for gestational hypertension. Conclusion: The study found greater pregnancy weight gain and higher pre-pregnancy BMI is independent risk factor for the occurrence of pregnancy hypertension.

Does solar heated structure mimicking greenhouse effective to impede winter growth reduction of some tropical fishes?

Winter reduction of fish growth is one of the major concerns in aquaculture. Using the principle of greenhouse mediated raised temperature, the issue has been addressed by examining the growth responses of some tropical fishes in polyculture (rohu, mrigal, bata, Japanese punti, grass carp, common carp, magur, freshwater prawn) and two stocking ratios (80:20 and 20:80) with surface and column feeder (catla, silver carp, rohu, Japanese punti and bata) and bottom feeder (mrigal and common carp). Advanced fry of these fishes were introduced separately in solar heated greenhouse and in open polyhouse (13 × 1.5 × 2 m3) placed in triplicate in a pond and reared for 120 or 98 days during the winter for two consecutive years. The rate of survival (20–83%) and net weight gained by different species of fish were distinctly higher in closed set up (0.22–2.95 g/day) than in open (4–66%; 0.11–1.80 g/day) ones in both trials. Among the species, warmth induced net weight gain was maximal for Japanese punti (196 g), followed by rohu (159 g), mrigal (115 g), grass carp (104 g), bata (36 g) and freshwater prawn (28 g) in polyculture. The frequency distribution of harvested fishes was skewed towards large fishes in solar heated greenhouse and smaller ones in open units. Water temperature ranged from 21.6–28.1 °C and 17.2–23.7 °C in the closed and open units, whereas mean temperature remained 4.5–5 °C higher in the former than in latter. There was no marked differences in total alkalinity (219–231 mg/l), inorganic carbon (289–417 mg/l), organic carbon (4.27–4.52 mg/l), dissolved oxygen (6.61–6.75 mg/l), total dissolved solids (420.48–423.74 mg/l) and conductivity (549.83–563.29 μs/cm) between the closed and open enclosures, and remained within the range for fish culture. The score values of the sum total of the integrated ecological conditions revealed that ~ 5 °C rise in water temperature during winter enhanced as high as 36% increased yield of fish (2546 kg/ha) over open units mediated through microbial driven augmented manure mineralization leading to increased primary productivity, zooplankton abundance and ecological integrity. In essence, the solar heated greenhouse would be of considerable use for circumventing the retarded growth during winter in tropical fishes.

Effects of tulsi leaves and ginger solution on growth performance and hematological profiles of broilers

This study was conducted to determine the efficacy of tulsi and ginger as a growth promoter in broilers. A total of thirty day old chicks (DOC) were purchased from CP Bangladesh Ltd. and after seven days divided into three groups (A), (B) and (C). No vaccination schedule was practiced and no antibiotics were added in ration. The (A) group was not supplemented with tulsi and ginger solution in drinking water. The (B) group was supplemented with tulsi solution @ 1ml/litre in drinking water and (C) group was supplemented with ginger solution @ 1 ml/litre in drinking water for consecutive 5 weeks started from 7th day of experiment. Weekly observations were recorded for live body weight gain up to 6th weeks and routine blood test was performed at 21st and 42nd days, to find out hematological changes between control and treatment groups. The FCR value of group (A) was 2.25, in group (B) was 1.99 and in group (C) was 1.90. From this initial study this may be concluded that production of broilers in by using tulsi and ginger was economic than control group. In Bangladesh broilers production is mainly organized by unemployed and its demand is very high because it supports marketing within 35–42 days. Short return of money but major problems is cost of production. The initial body weight (gm) of group (A), (B) and (C) on 7th of day experiment were 168±8.54, 166±7.95 and 166±7.90 gm respectively and after 42nd day of experiment final body weight were 1561±12.10, 1698±12.87 and 1763±13.28 gm respectively. The net body weight gain were 1393±11.07, 1533±11.98 and 1588±12.10 gm respectively and economics of production were analyzed and found that net profit per broiler was 18.82, 36.13 and 42.53 Tk respectively. It is concluded that broiler production by using herbal extract may be profitable and suitable for human consumption.&#x0D; Asian Australas. J. Biosci. Biotechnol. 2018, 3 (2), 143-149

Characterization of alloy 3033 after exposure to superheated steam at 800°C

Alloy 3033 was evaluated in superheated steam (SHS) at 800°C for a duration of 3000 hours. The SHS was able to simulate the supercritical water (SCW) condition at higher temperatures which no commercial SCW rig is currently capable of reaching. After exposure to the SHS, the weight change and surface oxide formation of Alloy 3033 were analyzed. Alloy 3033 had an initial weight gain after 1000 hours; however, the net weight gain reduced after 2000 and 3000 hours of exposure, suggesting oxide spallation. Formation of both Cr2O3 and MnCr2O4 was observed on the surface after 2000 and 3000 hours of SHS exposure. However, as exposure progressed, the XRD peak intensity ratio of MnCr2O4 to Cr2O3 decreased, in addition to the observation of more exposed Cr2O3. Based on this preliminary investigation, Alloy 3033 may not be suitable for extended use in SHS due to weight loss associated with oxide spallation.

Growth and blood profile of broiler rabbits on probiotic supplementation

A study was conducted to evaluate the effects of dietary supplementation of probiotic (Saccharomyces cerevisiae and Lactobacillus sporogenes) on growth, blood profile and economic traits of broiler rabbits. Thirty weaned Soviet Chinchilla rabbits were randomly divided into three groups and fed experimental diets for a period of 8 weeks. The three treatments were-T1: basal diet without probiotic supplementation (control), T2: basal diet + probiotic supplementation @ 0.5 g/kg of feed and T3: basal diet + probiotic supplementation @ 1.0 g/kg of feed. The net body weight gain was significantly (P<0.01) higher in T2 (1545.1) and T3 (1572.8g) han T1 (1370.1). Total feed intake was comparable among the different groups. The feed conversion ratio was better in T3 (3.99) and T2 (4.05) probiotic supplemented groups compared to the control (4.67). The return from of rabbit was higher in T 2 and T 13 than in T. No significant differences were observed in blood metabolites except serum cholesterol which reduced significantly (P<0.05) in probiotic supplemented groups T2 (64.40) and T3 (60.40) than the control (70.00 mg/dl).The results indicated that dietary supplementation of probiotic (@ 0.5 g/kg of feed) in weaner rabbits improved body weight gain, feed conversion ratio and reduced serum cholesterol level along with more economic returns.

Growth Performance and Blood Metabolites of Kankrej Heifers Fed Different Ratios of Green and Dry Fodder

A study was conducted to evaluate the effect of feeding different ratios of dry matter intake from green and dry fodder on growth performance and blood metabolites of Kankrej heifers. Thirty Kankrej calves of six months age were divided into three treatment groups. The T1 group was fed with 50% dry matter (DM) from green fodder, 20% DM from dry fodder and 30% DM from concentrate mixture; T2 group was fed with 35% DM from green fodder and 35% DM from dry fodder and 30% DM from concentrate mixture and T3 group was fed with 20% DM from green fodder, 50% DM from dry fodder and 30% DM from concentrate mixture. Net body weight gain was higher (P

Patients Less Likely to Lose Weight Following a Knee Replacement: Results From the Osteoarthritis Initiative.

Knee replacement typically results in reduced pain and improved function, but it is unclear if these improvements lead to weight loss. The purpose of this study was to examine weight change patterns preoperatively and postoperatively among overweight/obese knee replacement patients. The study evaluated 210 overweight/obese patients from the Osteoarthritis Initiative who underwent a knee replacement during an 8-year longitudinal study. Average annual weight changes during 1- to 2-year intervals prior to, including, and subsequent to knee replacement were categorized as loss (≥-2.5%), maintain (>-2.5% to <2.5%), and gain (≥2.5%). Weight changes across time intervals were compared using logistic regression with generalized estimating equations, adjusting for demographic, health, and knee factors. On average, patients lost -0.6 kg/y during the interval when the surgery was performed, but weight gain (0.9 kg/y) in the initial postoperative interval represented an overall net weight gain (0.3 kg/y) compared with presurgery. Continued weight gain (0.3 kg/y) was also seen among patients with additional follow-ups. Patients were significantly less likely to have a meaningful weight loss in the time interval immediately following the surgery compared with the interval in which the surgery took place (odds ratio, 0.37; 95% confidence interval, 0.18-0.79). Overweight and obese patients initially lost weight during the interval including knee replacement; however, they were less likely to lose more than 2.5% of their weight in the 1 to 2 years immediately after the surgery. Knee replacement patients may benefit from weight management interventions both preoperatively and postoperatively.

Validation study of the Colorado Model for predicting ROP

The Colorado ROP (CO-ROP) model uses birth weight (BW), gestational age (GA), and net weight gain at 28 days old (WG-28) to predict risk of retinopathy of prematurity (ROP). We sought to validate the CO-ROP model’s performance in a large multicenter cohort of at-risk infants.

Filter Processing and Gravimetric Analysis for Suspended Particulate Matter Samples

Aerosol sampling onto filter media with laboratory weighing before and after drawing air through the filter is the most commonly applied method to determine PM2.5 and PM10 concentrations. Although simple in concept, determining the net gain in weight from an aerosol deposit is complicated by adsorption of gases onto the filter, retention of water by the filter and the deposit, electrostatic charges that result in attraction of the filter to balance surfaces, contamination during filter handling, losses or additions to filter material, evaporation of semi-volatile aerosols, and inhomogeneous sample deposits. Additional restrictions apply when the weighed filters are submitted to subsequent chemical speciation analyses. A precisely controlled environment, with clean air and constant temperature and humidity, is required for filter weighing and processing, and filters must be equilibrated at these conditions. Balances must have sensitivities of ≤1 µg, be calibrated with well-established primary standards, and be regularly serviced. Ionizing sources are used to neutralize electrostatic charges. Regular quality control and quality assurance procedures involve filter inspection for defects before and after sampling, periodic balance zero and span checks, replicate filter weights, and independent system and performance audits.

Safety and efficacy of hyperosmolar irrigation solution in shoulder arthroscopy

A hyperosmolar irrigation solution has been reported to be safe and have potential benefits for use during shoulder arthroscopy in an animal model study. In this study, the clinical effects of a hyperosmolar solution were compared with a standard isotonic solution when used for shoulder arthroscopy. A prospective, double-blind, randomized controlled trial was performed to compare isotonic (273 mOsm/L) and hyperosmolar (593 mOsm/L) irrigation solutions used for arthroscopic rotator cuff repair. Primary outcomes focused on the amount of periarticular fluid retention based on net weight gain, change in shoulder girth, and pain. All patients were tracked through standard postsurgical follow-up to ensure no additional complications arose. Patients were contacted at 1 year to assess American Shoulder and Elbow Surgeon score, visual analog scale pain score, and the Single Assessment Numeric Evaluation shoulder scores RESULTS: Fifty patients (n = 25/group) were enrolled and completed the study. No statistically significant differences were noted between cohorts in demographics or surgical variables. The hyperosmolar group experienced significantly less mean weight gain (1.6 ± 0.82 kg vs. 2.25 ± 0.77 kg; P = .005), significantly less change in shoulder girth (P < .05), and a significantly lower immediate postoperative visual analog scale pain score (P = .036). At 1 year postoperatively, the differences between groups for American Shoulder and Elbow Surgeons, visual analog scale pain, and Single Assessment Numeric Evaluation were not significant (P > .2). A hyperosmolar irrigation solution provides a safe and effective way to decrease periarticular fluid retention associated with arthroscopic rotator cuff surgery without any adverse long-term effects. Use of a hyperosmolar irrigation solution for shoulder arthroscopy has potential clinical benefits to surgeons and patients.
