Higher Preimplantation Opioid Doses Associated With Long‐Term Spinal Cord Stimulation Failure in 211 Patients With Failed Back Surgery Syndrome

ObjectiveSpinal cord stimulation (SCS) is an effective treatment in failed back surgery syndrome (FBSS). We studied the effect of preimplantation opioid use on SCS outcome and the effect of SCS on opioid use during a two-year follow-up period.Materials and methodsThe study cohort included 211 consecutive FBSS patients who underwent an SCS trial from January 1997 to March 2014. Participants were divided into groups, which were as follows: 1) SCS trial only (n = 47), 2) successful SCS (implanted and in use throughout the two-year follow-up period, n = 131), and 3) unsuccessful SCS (implanted but later explanted or revised due to inadequate pain relief, n = 29). Patients who underwent explantation for other reasons (n = 4) were excluded. Opioid purchase data from January 1995 to March 2016 were retrieved from national registries.ResultsHigher preimplantation opioid doses associated with unsuccessful SCS (ROC: AUC = 0.66, p = 0.009), with 35 morphine milligram equivalents (MME)/day as the optimal cutoff value. All opioids were discontinued in 23% of patients with successful SCS, but in none of the patients with unsuccessful SCS (p = 0.004). Strong opioids were discontinued in 39% of patients with successful SCS, but in none of the patients with unsuccessful SCS (p = 0.04). Mean opioid dose escalated from 18 ± 4 MME/day to 36 ± 6 MME/day with successful SCS and from 22 ± 8 MME/day to 82 ± 21 MME/day with unsuccessful SCS (p < 0.001).ConclusionsHigher preimplantation opioid doses were associated with SCS failure, suggesting the need for opioid tapering before implantation. With continuous SCS therapy and no explantation or revision due to inadequate pain relief, 39% of FBSS patients discontinued strong opioids, and 23% discontinued all opioids. This indicates that SCS should be considered before detrimental dose escalation.

Barrett’s esophagus: Review of natural history and comparative efficacy of endoscopic and surgical therapies

Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Progression to cancer typically occurs in a stepwise fashion through worsening dysplasia and ultimately, invasive neoplasia. Established EAC with deep involvement of the esophageal wall and/or metastatic disease is invariably associated with poor long-term survival rates. This guides the rationale of surveillance of Barrett’s in an attempt to treat lesions at an earlier, and potentially curative stage. The last two decades have seen a paradigm shift in management of Barrett’s with rapid expansion in the role of endoscopic eradication therapy (EET) for management of dysplastic and early neoplastic BE, and there have been substantial changes to international consensus guidelines for management of early BE based on evolving evidence. This review aims to assist the physician in the therapeutic decision-making process with patients by comprehensive review and summary of literature surrounding natural history of Barrett’s by histological stage, and the effectiveness of interventions in attenuating the risk posed by its natural history. Key findings were as follows. Non-dysplastic Barrett’s is associated with extremely low risk of progression, and interventions cannot be justified. The annual risk of cancer progression in low grade dysplasia is between 1%-3%; EET can be offered though evidence for its benefit remains confined to highly select settings. High-grade dysplasia progresses to cancer in 5%-10% per year; EET is similarly effective to and less morbid than surgery and should be routinely performed for this indication. Risk of nodal metastases in intramucosal cancer is 2%-4%, which is comparable to operative mortality rate, so EET is usually preferred. Submucosal cancer is associated with nodal metastases in 14%-41% hence surgery remains standard of care, except for select situations.     

Process of forgiveness in the recovery of Chinese women survivors of intimate partner violence: Empowerment,transformation, and integration

Forgiveness has been found one substantial element in the recovery for women survivors from intimate partner violence following the termination of the abusive relationship. To further investigate the details of forgiveness in this specific context, the present study explored the process of forgiveness using grounded theory. In-depth and semi-structured interviews were conducted with 25 Chinese women survivors of IPV. The findings suggest that forgiveness is a strength-based process including empowerment, transformation, and integration phases. In the empowerment phase, survivors obtain strength at the intrapersonal, behavioural, and interpersonal levels. In the transformation phase, survivors complete cognitive transformation for their IPV experiences and emotional transformation towards former partners. In the integration phase, survivors—now freed from the past—reflect upon and apply the changes they have undergone. Two trajectories in the process were found. One trajectory is going through stages sequentially and the other trajectory is experiencing back and forth between empowerment and transformation stages before moving into the integration stage. The study's findings broaden our knowledge of the strength-based forgiveness process that women survivors of IPV undergo during recovery. Practitioners and policymakers could develop programmes and policies that support forgiveness by holistically facilitating their recovery and empowerment like assistance in dealing with life difficulties and promoting their reconnection with social networks. To improve the transferability and validity of the findings, the forgiveness of survivors of IPV could be explored in a diverse sample (e.g., survivors with low educational background or live in the rural area).

三阴性乳腺癌治疗的研究进展

三阴性乳腺癌（triple negative breast cancer，TNBC）是雌激素受体(estrogen receptor，ER)、孕激素受体（progesterone receptor，PR）及人类表皮生长因子受体（human epidermal growth factor-2,HER-2）均不表达的乳腺癌。按其功能特征可归纳为5类分子分型:以DNA修复缺陷或生长因子为途径的基底细胞样三阴性乳腺癌；以上皮-间充质转化和肿瘤干细胞为特征的间质样三阴性乳腺癌；免疫调节型三阴性乳腺癌；雄激素受体过表达的管腔／分泌型三阴性乳腺癌；HER-2富集型三阴性乳腺癌。三阴性乳腺癌恶性程度高且异型性较大，其治疗困难且预后较差，内分泌治疗及靶向治疗不敏感。目前很多学者对于三阴性乳腺癌的治疗各有研究，并有临床试验证实下述治疗有效。
