    Estetisk kirurgi: En kvantitativ studie om hur subjektiva upplevelser kring familj påverkar intresse av estetisk kirurgi2011Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Aim

    The purpose of this study is to explain how subjective experiences around the family affect interest in esthetic surgery. Specific questions were made to investigate this:

    - How is the interest in esthetic surgery affected by family members who has been talking about undergoing or have been undergoing esthetic surgery?

    - How is the interest in esthetic surgery affected by the experience of divorce during childhood and growing up with a single parent?

    - How is the interest in esthetic surgery affected by physical or psychological absence of mother or father, during childhood?

    - How is the interest in esthetic surgery affected by at least one person who has been supported and loving, during childhood?

    - How is the interest in esthetic surgery affected by family functions that are unmet?

    - How is the interest in esthetic surgery affected by the experience of a family crisis?

    Method

    This thesis has used a quantitative research method, with a survey. An own survey was made, and handed out in Stockholm. 60 surveys was handed out, of which 58 was answered. The survey was managed anonymously, and at first consolidated in spreadsheets of Excel and then analyzed in SPSS, trough Mann-Whitney and Chi-2 test, and also logistic regression.

    Results

    The predictors of interest in esthetic surgery are parents who talked about undergoing esthetic surgery (P = 0.049), lower estimates of mental presence of the mother (P = 0.029), lower estimates of mental presence of father (P = 0.042), lower estimate of that the father has given respect of the own person´s value (P = 0.001) and lower estimation of that the family have provided a good basis for a stable and harmonious childhood (P = 0.003). None of these could individually explain the dependent variable's variation, but all of them interacted. By gradually exclude the predictors in a logistic regression, the main predictor of interest in esthetic surgery was identified, which was the last one mentioned.

    Conclusions

    The conclusion is that certain subjective experiences around the family affect interest in cosmetic surgery, while the influence of others has shown no significant differences.

    A new hamstring test to complement the common clinical examination before return to sport after injury2010In: Knee Surgery, Sports Traumatology, Arthroscopy, ISSN 0942-2056, E-ISSN 1433-7347, Vol. 18, no 12, p. 1788-1803Article in journal (Refereed)
    Abstract [en]

    PURPOSE: The aim was to introduce and evaluate the reliability and validity of an active hamstring flexibility test as a complement to common clinical examination when determining safe return to sport after hamstring injury.

    METHODS: Eleven healthy subjects (28 years) were tested on repeated occasions, and 11 athletes (21 years) with MRI-verified acute hamstring strain were tested when common clinical examination revealed no signs of remaining injury, i.e. there was no differences between the legs in palpation pain, manual strength tests, and passive straight leg raise. Flexibility, i.e. highest range of motion of three consecutive trials, was calculated from electrogoniometer data during active ballistic hip flexions and conventional passive slow hip-flexions in a supine position. A VAS-scale (0-100) was used to estimate experience of insecurity during active tests.

    RESULTS: No significant test-retest differences were observed. Intra-class correlation coefficients ranged 0.94-0.99 and coefficients of variation 1.52-4.53%. Active flexibility was greater (23%) than passive flexibility. In the athletes, the injured leg showed smaller (8%) active, but not passive, flexibility than the uninjured leg. Average insecurity estimation was 52 (range 28-98) for the injured and 0 for the uninjured leg, respectively.

    CONCLUSION: The new test showed high reliability and construct validity; furthermore, it seems to be sensitive enough to detect differences both in active flexibility and in insecurity after acute hamstring strains at a point in time when the commonly used clinical examination fails to reveal injury signs. Thus, the test could be a complement to the common clinical examination before the final decision to return to sport is made.

    Weight loss, adverse events, and loss to follow-up after gastric bypass in young versus older adults: A Scandinavian Obesity Surgery Registry study.2018In: Surgery for Obesity and Related Diseases, ISSN 1550-7289, E-ISSN 1878-7533, Vol. 14, no 9, p. 1319-1326, article id S1550-7289(18)30324-1Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Young adults display particularly poor weight loss in behavioral obesity treatment; nonetheless, they have seldom been included in bariatric research.

    OBJECTIVES: To compare weight loss, adverse events, and loss to follow-up in young (18-25 yr) versus older (≥26 yr) adults up to 5 years after Roux-en-Y gastric bypass.

    SETTING: Nationwide, register-based study, Sweden.

    METHODS: Prospective registry data (Scandinavian Obesity Surgery Register) were analyzed in young (22.2 yr [standard deviation (SD): 2.1], 81.6% women, mean body mass index 43.7 kg/m2 [SD: 5.4]) and older (42.6 years [SD: 9.6], 82.0% women, mean body mass index 43.4 kg/m2 [SD: 5.0]) adults undergoing Roux-en-Y gastric bypass. Groups were matched for body mass index, sex, and year of surgery. Regression analyses and mixed models were used to compare outcomes between groups.

    RESULTS: A total of 369 young (37.0% of eligible) and 2210 older (46.1%) adults attended the 5-year follow-up. At this time, weight loss was 31.8% in young and 28.2% in older adults (P < .001), with a serious adverse event (Clavien-Dindo ≥3b) being reported in 52 (14.1%) young and 153 (6.9%) older adults (odds ratio = 2.06, 95% confidence interval: 1.45-2.92, P < .001). Loss to follow-up was higher in young versus older adults throughout the study period (range of relative risk = 1.16-1.89, P < .001).

    CONCLUSIONS: While young adults displayed at least equal weight loss as older adults, rates of adverse events were approximately doubled, and loss to follow-up rates were higher. Future studies on the significance of and the etiology behind the higher incidence of serious adverse events are needed. Intensified clinical contact post Roux-en-Y gastric bypass should have the potential to further improve outcomes in young adults.

    Improved Muscle Mitochondrial Capacity Following Gastric Bypass Surgery in Obese Subjects.2016In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 26, no 7, p. 1391-7Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Weight loss resulting from low-calorie diets is often less than expected. We hypothesized that energy restriction would influence proton leakage and improve mitochondrial efficiency, leading to reduced energy expenditure, partly explaining the difficulties in weight loss maintenance.

    METHODS: Eleven women with a median BMI of 38.5 kg/m(2) (q-range 37-40), and referred to gastric bypass surgery participated. Before surgery, and at 6 months of follow-up, muscle biopsies were collected from the vastus lateralis muscle. Mitochondria were isolated and analyzed for coupled (state 3) and uncoupled (state 4) respiration and mitochondrial capacity (P/O ratio).

    RESULTS: At follow-up, the participants had a median BMI of 29.6 kg/m(2) (28.3-32.0). State 3 increased from 20.6 (17.9-28.9) to 34.9 nmol O2/min/U citrate synthase (CS) (27.0-49.0), p = 0.01, while state 4 increased from 2.8 (1.8-4.2) to 4.2 nmol O2/min/U CS (3.1-6.1), although not statistically significant. The P/O ratio increased from 2.7 (2.5-2.8) to 3.2 (3.0-3.4), p = 0.02, indicating improved mitochondrial efficiency.

    CONCLUSIONS: Six months after gastric bypass surgery, the mitochondrial capacity for coupled, i.e., ATP-generating, respiration increased, and the P/O ratio improved. Uncoupled respiration was not enhanced to the same extent. This could partly explain the decreased basal metabolism and the reduced inclination for weight loss during energy restriction.

    The preoperative level of physical activity is associated to the postoperative recovery after elective cholecystectomy - A cohort study.2015In: International Journal of Surgery, ISSN 1743-9191, E-ISSN 1743-9159, Vol. 19, p. 35-41Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: There is an increasing interest in the role of preoperative physical activity for postoperative recovery. The effect of preoperative physical activity and recovery after cholecystectomy is unknown. The aim of this study was to evaluate the association of self-reported leisure-time preoperative physical activity with postoperative recovery and complications after elective cholecystectomy due to gallstone disease.

    METHODS: Prospective observational cohort study with 200 patients scheduled to undergo elective cholecystectomy. Level of self-assessed leisure-time physical activity was compared with recovery.

    RESULTS: Regular physical activity was associated with a higher degree of return to work within three weeks post-operatively (relative chance (RC) 1.26, p = 0.040); with a higher chance of leaving hospital within one day post-op (RC 1.23, p = 0.001), as well as with better mental recovery (RC 1.18, p = 0.049), compared to physically inactive. No statistically significant association was seen with return to work within one week or with self-assessed physical recovery.

    DISCUSSION: In clinical practice, evaluating the patients' level of physical activity is feasible, and may potentially be used to identify patients being more suitable for same-day surgery. Given the study design, the results from this study cannot prove causality.

    CONCLUSION: The present study shows that the preoperative leisure-time physical activity-level, is positively associated with less sick leave, a shorter hospital stay and with better mental recovery, three weeks post-elective cholecystectomy. We recommend assessing the physical activity-level preoperatively for prognostic reasons. If preoperative/postoperative physical training will increase recovery remains to be shown in a randomized controlled study.
