Objectives: To present a case of uterine necrosis following hemostatic suturing to control postpartum bleeding, and to review the literature in order to identify the suture techniques employed, clinical findings, diagnostics and treatment in the clinical cases described., Material and Methods: A 34-year-old woman presenting with abdominal pain eight days after cesarean delivery due to placenta previa who required B-Lynch compression suture due to uterine atony, and who was diagnosed with uterine necrosis. The patient underwent total abdominal hysterectomy with a satisfactory recovery. A systematic literature search was conducted in the Medline vía Pubmed, Embase and Web of Science databases. The search included case series and reports, and cohorts of women with uterine necrosis following the use of uterine compression sutures for postpartum bleeding. The analysis included sociodemographic and clinical variables at the time of diagnosis, suturing technique, diagnostic tests and treatment., Results: Overall, 23 studies with 24 patients were included. Of all necrosis cases, 83% occurred following cesarean section. B-Lynch was the suturing technique most frequently used (66 %), followed by the Cho suture (25 %). The most frequent symptoms were fever and abdominal pain. The most commonly used diagnostic test was computed tomography (9/24 cases). Hysterectomy was performed in the majority of cases (75 %)., Conclusions: Although rare, uterine wall necrosis is a serious complication. It would be advisable to design follow-up cohort studies of women undergoing these procedures in order to determine the incidence of associated complications.

Background & Aims: Cancer survival rates have increased significantly creating more awareness for comorbidities affecting the Quality of Life. Chemotherapy may induce serious metabolic alterations. These complications can create an energy imbalance, worsening prognosis. The effect of chemotherapy on energy metabolism remains largely unknown. The purpose of this systematic review is to determine the impact of chemotherapy on energy metabolism, creating more insight in a patients' energy requirements., Methods: We identified relevant studies up to May 2nd, 2019 using PubMed and Web of Science. Studies including all types of cancer and stages were selected. Only patients that underwent chemotherapy whether or not followed by surgery or radiotherapy were selected. Maximum follow-up was set at 6 months. Resting energy expenditure (REE), measured by indirect calorimetry (IC) or predicted by the Harris-Benedict equation (HB Eq ), was our primary outcome. Results regarding body composition were considered as secondary outcome parameter., Results: 16 studies were selected, including 267 patients. Overall, a significant decrease in REE [-1.5% to -24.91%] 1-month post-chemotherapy was reported. Two studies on breast cancer conducted a 3 and 6-month follow-up and found an increase in REE of 4.01% and 5.72% (p < .05), revealing a U-shaped curve in the expression of REE. Changes are accompanied by (non)significant variations in body composition (Fatmass (FM) and Fatfree Mass (FFM)). HB Eq tends to underestimate REE by 4.03%-27.1%., Conclusion: Alterations in REE, accompanied by changes in body composition, are found during and after chemotherapy in all cancer types and stages, revealing a U-shaped curve. Changes in FFM are suggested to induce variations in REE concomitant to catabolic effects of the disease and administered drug. HB Eq tends to underestimate REE, stressing the need for adequate assessment to meet patients' energy requirements and support dietary needs., (Copyright © 2019 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Although cancer survivorship has improved over the last decades, numbers of cancer incidence and prevalence are rising. Evidence is growing that lifestyle factors, such as physical activity, a healthy weight management and -diet, play an important role in first- and second line preventive strategies. When implementing a healthy lifestyle, the maintenance of the energy balance should be taken into account. The energy equilibrium is achieved when the energy intake (Ei) for one day is equal to the total daily energy expenditure (TEE). The latter is, among others, made up of the resting energy expenditure, its largest contributor (60-80% of TEE), and can be assessed by indirect calorimetry (i.e. the gold standard). The resting energy expenditure reflects the individual's minimal caloric need in 24h to support basal functions. In cancer patients, energy imbalances, expressed as a positive (Ei > TEE) or negative (Ei & TEE) energy balance, may occur and are characterised by weight gain or -loss respectively. As a corollary, shifts in fatmass and fatfree mass are reported. Adequate nutritional follow-up is necessary in order to meet the energy needs, since both positive and negative energy balances are known to have deteriorating effects on cancer prognosis and mortality. In the clinical setting, predictive formulas (e.g. Harris-Benedict equation) are often used to estimate the caloric need. However, both under- and overfeeding are reported when using equations. Therefore, we advise to use indirect calorimetry in the standard assessment of a patient's energy need in order to provide adequate metabolic coaching and -follow up.
