Biopsychosocial rehabilitation in the working population with chronic low back pain: a concept analysis.

OBJECTIVE: To identify the essential attributes of biopsychosocial rehabilitation for chronic low back pain in the working population. DESIGN: A concept analysis was conducted according to the 8-step method of Walker and Avant. This framework provides a clear concept and theoretical and operational definitions. METHODS: Five databases were searched, followed by a systematic screening. Subsequently, attributes, illustrative cases, antecedents, consequences and empirical referents were formulated. RESULTS: Of the 3793 studies identified, 42 unique references were included. Eleven attributes were identified: therapeutic exercise, psychological support, education, personalization, self-management, participation, follow-up, practice standard, goal-setting, social support, and dietary advice. Subsequently, illustrative cases were described. Antecedents, such as motivation, preparedness and a multidisciplinary team, were found, together with consequences such as decreased pain, less sick-leave and increased function and work status. Finally, examples of empirical referents were given. CONCLUSION: This study identified the attributes that are necessary to develop biopsychosocial rehabilitation intervention programmes for chronic low back pain. The defined concept of biopsychosocial rehabilitation for chronic low back pain may serve as a solid base to further develop and apply interventions. Future research should focus on the objectification of biopsychosocial rehabilitation and conceptualization regarding how personalization is done.

Personalised rehabilitation to improve return to work in patients with persistent spinal pain syndrome type II after spinal cord stimulation implantation: a study protocol for a 12-month randomised controlled trial-the OPERA study.

BACKGROUND: For patients with therapy-refractory persistent spinal pain syndrome type II (PSPS-T2), spinal cord stimulation (SCS) may serve as an effective minimally invasive treatment. Despite the evidence that SCS can improve return to work (RTW), only 9.5 to 14% of patients implanted with SCS are effectively capable of returning to work. Thus, it seems that current post-operative interventions are not effective for achieving RTW after SCS implantation in clinical practice. The current objective is to examine whether a personalised biopsychosocial rehabilitation programme specifically targeting RTW alters the work ability in PSPS-T2 patients after SCS implantation compared to usual care. METHODS: A two-arm, parallel-group multicentre randomised controlled trial will be conducted including 112 patients who will be randomised (1:1) to either (a) a personalised biopsychosocial RTW rehabilitation programme of 14 weeks or (b) a usual care arm, both with a follow-up period until 12 months after the intervention. The primary outcome is work ability. The secondary outcomes are work status and participation, pain intensity, health-related quality of life, physical activity and functional disability, functional capacities, sleep quality, kinesiophobia, self-management, anxiety, depression and healthcare expenditure. DISCUSSION: Within the OPERA project, we propose a multidisciplinary personalised biopsychosocial rehabilitation programme specifically targeting RTW for patients implanted with SCS, to tackle the high socio-economic burden of patients that are not re-entering the labour market. The awareness is growing that the burden of PSPS-T2 on our society is expected to increase over time due to the annual increase of spinal surgeries. However, innovative and methodologically rigorous trials exploring the potential to decrease the socio-economic burden when patients initiate a trajectory with SCS are essentially lacking.

Micronutrient supplementation in pregnancies following bariatric surgery: a practical review for clinicians.

Patients who have undergone bariatric surgery are at high risk for nutritional deficiencies before and after surgery if no proper supplementation and close follow-up are maintained. As pregnancies after these surgeries are occurring more frequently, deficiencies imply risks for both mother and child. Nutritional needs for this specific population are different from that of patients with obesity or a non-bariatric population. This review provides a comprehensive summary of the most described vitamins and minerals during pregnancy, after bariatric surgery, and during pregnancy after bariatric surgery in order to summarize their specific needs and possible side effects and to provide a useful guideline to the involved caregivers.

Pregnancy after Bariatric Surgery: A Nested Case-Control Study of Risk Factors for Small for Gestational Age Babies in AURORA.

Bariatric surgery prior to pregnancy is a significant risk factor for small for gestational age (SGA) babies. This case-control study investigated differences between mothers delivering an SGA baby following bariatric surgery, compared to those delivering an appropriate for gestational age (AGA) baby. Out of 129 babies born to mothers in the AURORA cohort study, 25 were SGA (<10th percentile) and 97 were AGA (10th-90th percentile). Higher gestational weight gain (GWG) was significantly associated with decreased odds of SGA (aOR per kg 0.92, 95% CI 0.85-0.99). According to the Institute of Medicine GWG guidelines, 44% of SGA mothers had 'inadequate' GWG compared to 17% of AGA mothers. Nearly half of the mothers had 'excessive' GWG yet still gave birth to an SGA or AGA baby. Mothers of SGA babies lost more weight following bariatric surgery (45.6 ± 14.4 kg vs. 39.0 ± 17.9 kg). Women who reported receiving nutritional advice following bariatric surgery were significantly less likely to have an SGA baby (aOR 0.15, 95% CI 0.0.4-0.55). Women with a history of bariatric surgery should be provided with specialized support before and during pregnancy to encourage adequate nutritional intake and weight gain to support healthy fetal growth.

Periconceptional Folate Supplementation in Women after Bariatric Surgery-A Narrative Review.

The prevalence of obesity is increasing globally, and along with it, there is a growing number of patients opting to undergo bariatric surgery to treat this condition. Whilst it has many advantages, bariatric surgery is known to induce micronutrient deficiency, with possible deleterious effects on overall health. This topic becomes even more relevant during pregnancy, where deficiencies can also affect the developing fetus, possibly being the cause of an increase in congenital anomalies. Most notably amongst these micronutrients is folate, or vitamin B9, which plays an essential role in development, gene expression and genomic stability. As insufficient levels of folate are associated with neural tube defects in the fetus, preventing and treating folate deficiencies during pregnancies after bariatric surgery is a relevant issue. Unfortunately, folate supplementation recommendations for bariatric patients who wish to become pregnant are not clear. In this narrative review, we discuss whether the recommendations for the general population are still valid for bariatric patients. Furthermore, we discuss the role of folate in the human body, folate status in both non-bariatric and bariatric patients, the various types of folate that are available for substitution and the risk associated with over-supplementation.

Gestational weight gain and postpartum weight retention after bariatric surgery: data from a prospective cohort study.

BACKGROUND: It is unknown whether international guidelines on gestational weight gain can be used in pregnancies after bariatric surgery. OBJECTIVES: To investigate gestational weight gain, intrauterine growth, and postpartum weight retention in postbariatric women. SETTING: 8 Belgian hospitals. METHODS: Prospective data from 127 postbariatric pregnancies from September 2014 through October 2018. Patients were grouped according to achievement of 2009 Institute of Medicine (IOM) guidelines. RESULTS: In 127 patients with a mean age of 30.2 years (standard deviation [SD], 4.7), the mean gestational weight gain was 12.5 kg (SD, 6.7). Of these patients, 24% (30 of 127) showed insufficient weight gain, 20% (26 of 127) showed adequate weight gain, and 56% (71 of 127) showed excessive weight gain. Of 127 patients, 27 (21%) had small-for-gestational-age infants. This peaked in the group with insufficient weight gain (47%; 95% confidence interval [CI], 29%-65%; P < .001). The prevalence of large-for-gestational-age infants was comparable between groups, although highest in the group with excessive weight gain (0% in those with insufficient weight gain, 4% in those with adequate weight gain, and 8% in those with excessive weight gain). Preterm births were recorded more in patients with insufficient weight gain (23%; 95% CI, 8%-38%; P = .048). The mean amounts of postpartum weight retained were 4.0 kg (SD, 7.4) at 6 weeks and 3.0 kg (SD, 9.1) at 6 months. Weight retention at 6 weeks (7.1 kg; 95% CI, 5.5-8.7; P < .001) and 6 months (8.3 kg; 95% CI, 4.5-12.2; P < .001) was highest in women gaining excessive weight. CONCLUSION: Achievement of IOM guidelines is low in postbariatric pregnancies. Insufficient weight gain increases the risk for small-for-gestational-age babies. Excessive weight gain increases weight retention after delivery and could precipitate weight regain. After bariatric surgery, women should be encouraged to achieve IOM recommendations.

Adiposity, psychomotor and behaviour outcomes of children born after maternal bariatric surgery.

BACKGROUND: Bariatric surgery before pregnancy can result in improved maternal fertility. However, long-term data on the consequences at childhood age are currently lacking. METHODS: EFFECTOR is a prospective cohort study of children (aged 4 to 11 years) born to mothers who underwent bariatric surgery (BS) before pregnancy (n = 36), controls with overweight/obesity (OW/OB) matched on pre-pregnancy BMI (n = 36) and normal weight controls (NL) (n = 35). We performed prospective collection of anthropometric data, data on psychomotor development, school functioning and behaviour (Strengths and Difficulties Questionnaire (SDQ), Child Behaviour Checklist (CBCL)). RESULTS: The children born after bariatric surgery (BS) presented with the highest body-weight SDS (0.70 vs 0.14 in OW/OB and -0.09 in NL; P = .006) and BMI SDS (0.47 vs -0.02 in OW/OB and -0.42 in NL; P = .01). A higher excess in body fat percentage and waist circumference SDS were found in the BS group (5.7 vs 1.4 in OW/OB and -0.1 in NL; P < .001 and 0.61 vs 0.16 in OW/OB and -0.15 in NL; P = .04). The SDQ questionnaires revealed a higher amount of overall problems in the BS offspring (11.1 vs 7.5 in OW/OB and 8.1 in NL; P = .03), with a higher externalizing score at the CBCL (52.0 vs 44.2 in OW/OB and 47.0 in NL; P = .03). CONCLUSION: Maternal bariatric surgery does not appear to protect the offspring for childhood overweight and obesity. Parents reported more behaviour problems in these children, especially externally of nature.

Pregnancy after bariatric surgery and adverse perinatal outcomes: A systematic review and meta-analysis.

BACKGROUND: Women who undergo bariatric surgery prior to pregnancy are less likely to experience comorbidities associated with obesity such as gestational diabetes and hypertension. However, bariatric surgery, particularly malabsorptive procedures, can make patients susceptible to deficiencies in nutrients that are essential for healthy fetal development. The objective of this systematic review and meta-analysis is to investigate the association between pregnancy after bariatric surgery and adverse perinatal outcomes. METHODS AND FINDINGS: Searches were conducted in Medline, Embase, PsycINFO, CINAHL, Scopus, and Google Scholar from inception to June 2019, supplemented by hand-searching reference lists, citations, and journals. Observational studies comparing perinatal outcomes post-bariatric surgery to pregnancies without prior bariatric surgery were included. Outcomes of interest were perinatal mortality, congenital anomalies, preterm birth, postterm birth, small and large for gestational age (SGA/LGA), and neonatal intensive care unit (NICU) admission. Pooled effect sizes were calculated using random-effects meta-analysis. Where data were available, results were subgrouped by type of bariatric surgery. We included 33 studies with 14,880 pregnancies post-bariatric surgery and 3,979,978 controls. Odds ratios (ORs) were increased after bariatric surgery (all types combined) for perinatal mortality (1.38, 95% confidence interval [CI] 1.03-1.85, p = 0.031), congenital anomalies (1.29, 95% CI 1.04-1.59, p = 0.019), preterm birth (1.57, 95% CI 1.38-1.79, p < 0.001), and NICU admission (1.41, 95% CI 1.25-1.59, p < 0.001). Postterm birth decreased after bariatric surgery (OR 0.46, 95% CI 0.35-0.60, p < 0.001). ORs for SGA increased (2.72, 95% CI 2.32-3.20, p < 0.001) and LGA decreased (0.24, 95% CI 0.14-0.41, p < 0.001) after gastric bypass but not after gastric banding. Babies born after bariatric surgery (all types combined) weighed over 200 g less than those born to mothers without prior bariatric surgery (weighted mean difference -242.42 g, 95% CI -307.43 to -177.40 g, p < 0.001). There was low heterogeneity for all outcomes (I2 < 40%) except LGA. Limitations of our study are that as a meta-analysis of existing studies, the results are limited by the quality of the included studies and available data, unmeasured confounders, and the small number of studies for some outcomes. CONCLUSIONS: In our systematic review of observational studies, we found that bariatric surgery, especially gastric bypass, prior to pregnancy was associated with increased risk of some adverse perinatal outcomes. This suggests that women who have undergone bariatric surgery may benefit from specific preconception and pregnancy nutritional support and increased monitoring of fetal growth and development. Future studies should explore whether restrictive surgery results in better perinatal outcomes, compared to malabsorptive surgery, without compromising maternal outcomes. If so, these may be the preferred surgery for women of reproductive age. TRIAL REGISTRATION: PROSPERO CRD42017051537.

Pregnancy after bariatric surgery: Consensus recommendations for periconception, antenatal and postnatal care.

The objective of the study is to provide evidence-based guidance on nutritional management and optimal care for pregnancy after bariatric surgery. A consensus meeting of international and multidisciplinary experts was held to identify relevant research questions in relation to pregnancy after bariatric surgery. A systematic search of available literature was performed, and the ADAPTE protocol for guideline development followed. All available evidence was graded and further discussed during group meetings to formulate recommendations. Where evidence of sufficient quality was lacking, the group made consensus recommendations based on expert clinical experience. The main outcome measures are timing of pregnancy, contraceptive choice, nutritional advice and supplementation, clinical follow-up of pregnancy, and breastfeeding. We provide recommendations for periconception, antenatal, and postnatal care for women following surgery. These recommendations are summarized in a table and print-friendly format. Women of reproductive age with a history of bariatric surgery should receive specialized care regarding their reproductive health. Many recommendations are not supported by high-quality evidence and warrant further research. These areas are highlighted in the paper.

Screening and Management of Gestational Diabetes Mellitus after Bariatric Surgery.

Gestational diabetes mellitus (GDM) is a frequent medical complication during pregnancy. This is partly due to the increasing prevalence of obesity in women of childbearing age. Since bariatric surgery is currently the most successful way to achieve maintained weight loss, increasing numbers of obese women of childbearing age receive bariatric surgery. Bariatric surgery performed before pregnancy significantly reduces the risk to develop GDM but the risk is generally still higher compared to normal weight pregnant women. Women after bariatric surgery therefore still require screening for GDM. However, screening for GDM is challenging in pregnant women after bariatric surgery. The standard screening tests such as an oral glucose tolerance test are often not well tolerated and wide variations in glucose excursions make the diagnosis difficult. Capillary blood glucose measurements may currently be the most acceptable alternative for screening in pregnancy after bariatric surgery. In addition, pregnant women after bariatric surgery have an increased risk for small neonates and need careful nutritional and foetal monitoring. In this review, we address the risk to develop GDM after bariatric surgery, the challenges to screen for GDM and the management of women with GDM after bariatric surgery.

Contraception, Menstruation, and Sexuality after Bariatric Surgery: a Prospective Cohort Study.

BACKGROUND: Women with a history of bariatric surgery are recommended to avoid pregnancy at least 12 months after surgery. Evidence on the impact of bariatric surgery on contraception, menstrual cycle, and sexuality in the first year postoperative is therefore indispensable. OBJECTIVES: The objective of this paper is to prospectively study changes in contraception, menstrual cycle and sexuality in women of reproductive age following bariatric surgery. SETTING: The study was conducted in two secondary medical centers and a tertiary academic medical center. METHODS: Women attending for bariatric surgery or who recently underwent bariatric surgery completed online questionnaires about contraception, menstrual cycle, and sexual behavior before surgery and 6 and 12 months after surgery. RESULTS: The study included data from 71 women, including 70 and 47 women at 6 and 12 months after bariatric surgery, respectively. Preoperatively, 43.6% (n = 31/71) used a short-acting hormonal contraceptive, the usage of which decreased significantly to, respectively, 32.8% (n = 23/70; p = .031) and 27.7% (n = 13/47; p = .022) 6 and 12 months post-surgery. Usage of long-acting contraceptive methods increased from 26.7% (n = 19/71) preoperatively to 38.6% (n = 27/70; p = .021) and 42.6% (n = 20/47; p = .004) at 6 and 12 months. Combined oral contraceptives (COC) remained used (39.4% preoperatively, 27.1 and 14.9% at 6 and 12 months postoperatively). Menstrual cycle (frequency, pattern, duration of the cycle, and the menstruation itself) and sexual behavior (intimate relationship, frequency of intercourse, and satisfaction) did not differ significantly before and after surgery. CONCLUSIONS: Women undergoing bariatric surgery appear to switch their type of contraceptive from oral, short-acting hormonal contraceptives to non-oral, long-acting contraceptives. No changes in menstrual cycle and sexual behavior were shown.
