The banning of all mesh for prolapse by the FDA has failed to recognize that there is a major difference between mesh sheets applied behind the vagina for POP and repair of POP by shortening and reinforcing damaged suspensory ligaments, much as is used in the midurethral sling (MUS) which retains endorsement by the FDA. Mesh sheets interfere with the vaginal elasticity essential for function and may cause pain and massive urine loss postoperatively, in some cases; tapes far less so, as they have little contact with vagina and work by shortening and reinforcing damaged ligaments in the same way as the MUS operation. The main pathogenesis of POP is leaching out of collagen after the menopause. Weakened ligaments cannot support the organs so they prolapse. Only artificial collagenous neoligaments created by implanted tapes (as per the MUS) can create the new collagen required to repair these ligaments. The major advances developed over the past 30 years for treatment of POP using these ligament repair techniques has in one stroke been abolished. The treatment of POP has been set back 100 years. In their twilight years, many women will suffer the consequences of loose posterior ligaments, major prolapse, urge, nocturia, chronic pelvic pain, obstructed micturition defecation and fecal incontinence. The FDA needs to reconsider its ban, at least for tapes, which are supported by individual, multicentre and long-term studies.

Abstract OBJECTIVE The aim of this study was to investigate the microsurgical results of symptomatic sacral perineurial cysts of 11 patients and to discuss the treatment options of the past 10 years. METHODS We retrospectively reviewed the records of 11 patients with symptomatic sacral perineurial cysts who underwent microsurgical treatment at Tongji Hospital, Huazhong University of Science and Technology from 1993 through 2006. The philosophy was to perform total or partial cyst wall removal, to imbricate the remaining nerve sheath if possible, and to repair local defect with muscle, Gelfoam (Pharmacia & Upjohn, Kalamazoo, MI), and fibrin glue. Patient outcomes were assessed by comparing the preoperative and postoperative examination results. The average follow-up time obtained from return visits to the neurosurgery clinic or by telephone questionnaires ranged from 2 months to 13 years. A literature search and analysis of current treatment options were performed. RESULTS Nine of the 11 patients (82%) experienced complete or substantial relief of their preoperative symptoms. One patient (Patient 4) experienced worsening of bladder dysfunction after surgery and recovered slowly to subnormal function during the subsequent 2 months. The symptoms of Patient 9 did not resolve, and magnetic resonance imaging showed that the cyst had reoccurred. The patient underwent reoperation 3 months later without any improvement. One patient (Patient 11) experience a cerebrospinal fluid leakage complication. Neither new postoperative neurological defects nor infection were observed in our series. In the literature, there are six different treatment options under debate and controversially discussed. CONCLUSION Microsurgical treatment yielded the best long-term resolution of patient symptoms to date and should be recommended to appropriately selected patients.

Awareness that our planet is a self-supporting biosphere with sunlight as its major source of energy for life has resulted in a long-term historical fascination with the workings of self-supporting ecological systems. However, the studies of such systems have never entered the canon of ecological or evolutionary tools and instead, have led a fringe existence connected to life support system engineering and space travel. We here introduce a framework for a renaissance in biospherics based on the study of matter-closed, energy-open ecosystems at a microbial level (microbial biospherics). Recent progress in genomics, robotics, and sensor technology makes the study of closed systems now much more tractable than in the past, and we argue that the time has come to emancipate the study of closed systems from this fringe context and bring them into a mainstream approach for studying ecosystem processes. By permitting highly replicated long-term studies, especially on predetermined and simplified systems, microbial biospheres offer the opportunity to test and develop strong hypotheses about ecosystem function and the ecological and evolutionary determinants of long-term system failure or persistence. Unlike many sciences, ecosystem ecology has never fully embraced a reductionist approach and has remained focused on the natural world in all its complexity. We argue that a reductionist approach to ecosystem ecology, using microbial biospheres, based on a combination of theory and the replicated study of much simpler self-enclosed microsystems could pay huge dividends.

Abstract Relapsed acute lymphoblastic leukemia (ALL) has remained challenging to treat in children, with survival rates lagging well behind those observed at initial diagnosis. Although there have been some improvements in outcomes over the past few decades, only ∼50% of children with first relapse of ALL survive long term, and outcomes are much worse with second or later relapses. Recurrences that occur within 3 years of diagnosis and any T-ALL relapses are particularly difficult to salvage. Until recently, treatment options were limited to intensive cytotoxic chemotherapy with or without site-directed radiotherapy and allogeneic hematopoietic stem cell transplantation (HSCT). In the past decade, several promising immunotherapeutics have been developed, changing the treatment landscape for children with relapsed ALL. Current research in this field is focusing on how to best incorporate immunotherapeutics into salvage regimens and investigate long-term survival and side effects, and when these might replace HSCT. As more knowledge is gained about the biology of relapse through comprehensive genomic profiling, incorporation of molecularly targeted therapies is another area of active investigation. These advances in treatment offer real promise for less toxic and more effective therapy for children with relapsed ALL, and we present several cases highlighting contemporary treatment decision-making.

During the past two decades, a number of dramatic changes have taken place in the treatment of infants born with myelomenmgocele. Since the development in the 1950's and early 1960's of more effective methods for treating hydrocephalus, urinary incontinence, and paraplegia, aggressive treatment regimes have been initiated. Numerous articles and editorials have questioned these various treatment modalities based on the lack of objective long-term studies documenting their effectiveness. More recently, dissatisfaction with the results of current surgical prodecures for children with myelomeningocele has led to the development of selective criteria for early treatment.1,2 The purpose of this commentary, however, is not to discuss the merits of selective treatment for myelomeningocele but rather to discuss some of the recent developments for the prevention of this disorder.

Abstract Introduction Hodgkin lymphoma (HL) represents ~10% of all lymphomas in the United States (US) with classical HL (cHL) accounting for ~95% of all HL cases. cHL has a bimodal age distribution with peaks at ages 15-39 and ≥75 years. As part of CONNECT, the first real-world survey in cHL to include physicians, patients, and caregivers, patient treatment preferences for those with stage III or IV cHL were explored and differences evaluated between those aged <40 years (corresponding to the upper end of the age range for adolescence and young adulthood [US National Cancer Institute]) and ≥40 years at diagnosis. Methods The CONNECT patient survey was a non-interventional patient-centered survey. Participants included were aged ≥18 years at the time of participation (aged ≥12 years at diagnosis), diagnosed with cHL within the past 10 years, and previously or currently being treated for cHL in the US. The CONNECT survey was reviewed and approved by the New England Institutional Review Board and administered from December 30, 2020, to March 1, 2021. Results In CONNECT, 182 participants had stage III or IV cHL (64% female; 77% Caucasian) with 64% aged <40 years at diagnosis. Overall, median (interquartile range) age at cHL diagnosis was 32 (25-50) years (aged <40, 27 [23-32] years; ≥40, 57 [49-64] years). Sixty-two percent of participants were diagnosed with stage III or IV cHL within the past 2 years and 27% were receiving treatment at time of survey. Cure was ranked as the first or second goal of initial cHL treatment for 86% of participants aged <40 years and 52% of participants aged ≥40 years (P < 0.001; Figure A). A higher percentage of participants aged ≥40 than <40 years ranked living longer (43% vs 28%) and having better quality of life (26% vs 8%, P = 0.001) as the first or second goal for initial cHL treatment. Among those with stage III or IV cHL in remission (<40, n=105; ≥40, n=11), 86% aged <40 and 100% age ≥40 years ranked staying in remission as the first or second most important survivorship goal. At diagnosis, a significantly higher percentage of participants aged <40 than ≥40 years preferred to treat their cancer aggressively (79% vs 60%, P = 0.016; Figure B). These participants were willing to trade off short-term risks for long-term efficacy (93% vs 71%, P < 0.001; Figure B). However, 44% of those aged <40 and 45% of those aged ≥40 years were willing to make that same trade-off for long-term risk reduction. A significantly higher percentage of participants aged <40 than ≥40 years reported being informed by their health care provider (HCP) about the following short-term side effects: nausea/vomiting (93% vs 80%, P = 0.015), hair loss (97% vs 74%, P < 0.001), fatigue (96% vs 74%, P < 0.001), risk of infection from low blood counts (90% vs 62%, P < 0.001), low blood count (87% vs 63%, P < 0.001), numbness and tingling (91% vs 45%, P < 0.001), and muscle weakness (74% vs 55%, P = 0.014). Regardless of age, fewer participants reported being told about the long-term risks of cHL treatment with those aged <40 years being more informed about the risk of developing other cancers (73% vs 55%; P = 0.028) and infertility (74% vs 22%; P < 0.001), and those aged ≥40 years being more informed about stroke (40% vs 13%; P < 0.001). Most participants reported being told about the short-term (<40 years, 85%; ≥40 years, 72%) and long-term (< 40 years, 75%; ≥40 years, 62%) side effects of cHL treatment during a discussion of treatment options with their HCP. When asked about long-term side effects of greatest concern, a significantly higher percentage of participants aged <40 compared with ≥40 years were concerned about secondary cancers (81% vs 46%; P < 0.001) and infertility (23% vs 6%; P = 0.007) whereas a significantly higher percentage of those aged ≥40 compared with those <40 years were concerned about heart disease and stroke (58% vs 42%; P = 0.046) and infections (31% vs 4%; P < 0.001). Conclusion Treatment goals differ significantly between participants with stage III or IV cHL based primarily on age, with those aged <40 years focusing on cure and aggressive treatments and those ≥40 years focusing on living longer and obtaining a good quality of life. Additionally, participants aged <40 compared with those ≥40 years were more willing to accept short-term risks in exchange for long-term benefits. Lastly, regardless of age, most participants were told about short-term and long-term side effects in discussion of treatment options with their HCP. Figure 1 Figure 1.

AbstractThis article offers a critical analysis of scholarship produced about Brazil's Banco Nacional de Desenvolvimento Econômico e Social (BNDES) since its founding, in 1952, to 2013. BNDES has performed an important, if changing and sometimes controversial, role in Brazil's economic development over the past 60 years, especially as provider of long-term finance. This analysis of almost 1,000 texts highlights discussions about its initial organisation and mission and how the role and activities of the bank changed over time, guided by turbulent national political and economic contexts. In spite of the bank's institutional importance, however, the literature is more narrative than analytical and of limited scholarly impact, dominated as it is by the bank's authorship. We argue for independent, evidence-driven, critical analyses of the effectiveness of this important institution in promoting Brazil's economic and social development.

AbstractPelvic venous diseases encompasses all chronic pathologies of pelvic veins caused by venous hypertension and retrograde flow in pelvic veins. It is commonly unexplained and often underdiagnosed cause of chronic pelvic pain in women of productive age. Pelvic venous pathologies are a part of multidisciplinary problem that should be considered in a holistic approach. Newly offered SVP classification may help correctly classifying patients and using the same nomenclature. Endovascular treatment options are highly effective with good long-term results. Patients with inconclusive gynecologists examinations should be referred to a specialist for the investigation of pelvic venous disorders.

Over the past three decades, the indications for the use of lasers have increased dramatically. Combined with the interest paid by the media, the volume of laser procedures has progressively increased, as has the number of complications arising from their use. Knowing the principles behind laser surgery can help minimize the potential for complications; however, as with all surgical procedures, in addition to excellent surgical results, undesirable results are inevitable. Laser technologies have evolved effectively these past decades with a broader spectrum of clinical applications accompanied by improved outcomes. Cutaneous lasers and lights are considered safe interventions with an associated rapid healing time. Post-treatment consequences are usually mild and spontaneously resolving, with erythema and edema lasting hours to days. More troublesome while less common adverse events include urticaria, erosions, blistering, infection, hyperpigmentation, hypopigmentation, burns and delayed re-epithelialization [2]. We present some clinical cases with some serious adverse effects of the laser treatments in women and men. There are some treatment options on how to reduce the complications or manage them without long term sequelae, however the clinical experience of the laser operator and the accurate device used influences the safety and the outcomes of the treatment.
