BACKGROUND
Laparoscopic sleeve gastrectomy (SG) achieves type 2 diabetes (T2D) remission to various extents, and reasons for such variations are unknown.
OBJECTIVES
We assessed patients' characteristics associated with T2D remission 1 year post SG.
SETTING
University hospital.
METHODS
Retrospective study of 230 T2D patients (18-64 yr) who underwent SG at our institution. We examined pre- and postoperative demographic, anthropometric, biochemical, and clinical characteristics associated with T2D complete remission, partial remission, improvement, or unchanged status. Independent predictors of T2D complete remission were assessed by binary logistic regression and then included in 7 predictive models. Logistic regression assessed the pre- and postoperative predictors of T2D complete remission and their predictive performance was measured with the area under the curve of the receiver operating characteristic curve.
RESULTS
A total of 230 patients were included in the study, females comprised 69%, and mean age was 45.66 ± 8.84 years. Mean preoperative weight and body mass index were 115.69 ± 20.76 kg and 43.53 ± 6.98 kg/m, respectively. Approximately two thirds (64.4%) of the sample had diabetes for >5 years. Insulin therapy users comprised 36.9% of the sample and 29.6% of patients were on ≥2 oral hypoglycemic agents (OHA). At 1 year, mean body mass index was 32.77 ± 6.09 kg/m, percent excess weight loss (%EWL) was 62.29 ± 23.60% and glycosylated hemoglobin (HbA1C) improved from 8.1% to 6.18%. Approximately 42.2% of the sample achieved T2D complete remission. Compared with those with no remission, patients with complete remission were significantly younger, had shorter duration of diabetes, were not on insulin therapy, took fewer OHA, had higher C-peptide, lower preoperative HbA1C, were less likely to have had hypertension or dyslipidemia, and more likely to have achieved higher %EWL. Seven proposed models for prediction of complete remission showed the most useful model comprised diabetes duration + pre-HbA1C + %EWL + insulin therapy + age + OHA (area under the curve = .81). Independent predictors of complete remission were preoperative HbA1C, %EWL, insulin therapy, age, and OHA (but not diabetes duration).
CONCLUSION
SG results in significant weight reduction and various extents of T2D remission. HbA1C, %EWL, insulin therapy, age, and OHA were independent predictors of complete remission. Assessing these factors before bariatric surgery is important to identify any modifiable characteristics that can be altered to increase the likelihood of remission.

Review
Mature T- and natural killer (NK)-cell neoplasms comprise a group of morphologically, immunophenotypically, molecularly, and clinically heterogeneous disorders with generally unfavorable outcome. Results of first-line chemotherapy are unsatisfactory for the most common T-cell lymphomas (peripheral T-cell lymphoma, not otherwise specified; angioimmunoblastic T-cell lymphoma; anaplastic large cell lymphomas; anaplastic lymphoma tyrosine kinase-negative) as well as for many other entities. High-dose therapy followed by autologous hematopoietic stem cell transplantation (HSCT) is widely recommended for consolidation after a complete or partial remission is achieved. However, about one-third of patients never reach transplantation because of early relapse or refractoriness. Targeted therapies have recently been developed; combinations with chemotherapy may improve outcomes, but long-term results from prospective studies are largely missing. In this situation, allogeneic HSCT remains a valuable treatment option inducing long-lived remissions in about 30% to 50% of patients with relapsed and refractory T-cell lymphoma able to proceed to transplantation. Results of allogeneic transplantation for consolidation in first remission are less defined and its indications remain controversial. With growing evidence that haploidentical HSCT also works in lymphoma, more patients can be brought to transplantation. Decreasing the morbidity and mortality of allogeneic transplantation is a continuous challenge. Integrating new drugs into transplant concepts and setting up prospective studies involving allogeneic transplantation remain unmet needs that warrant urgent study in a group of disorders in which classical chemotherapy and new drugs have generated results, which are far from optimal until today.

OBJECTIVE
The aim of this study was to assess whether the results obtained with 12 sessions of cognitive-behavioral group therapy with obsessive-compulsive patients were maintained after two years, and whether the degree of symptom remission was associated with relapse.
METHOD
Forty-two patients were followed. The severity of symptoms was measured at the end of cognitive-behavioral group therapy and at 18 and 24 months of follow-up. The assessment scales used were the Yale-Brown Obsessive-Compulsive Scale, Clinical Global Impression, Beck Depression Inventory, and Beck Anxiety Inventory.
RESULTS
The reduction in symptom severity observed at the end of treatment was maintained during the two-year follow-up period (F = 57.881; p < 0.001). At the end of the treatment, 9 (21.4%) patients presented full remission, 22 (52.4%) presented partial remission, and 11 (26.2%) had unchanged scores in the Yale-Brown Obsessive-Compulsive Scale. After two years, 13 patients (31.0%) presented full remission, 20 (47.6%) had partial remission, and 9 (21.4%) had unchanged Yale-Brown Obsessive-Compulsive Scale scores. The full remission of symptoms at the end of the treatment was a protective factor against relapse (chi2 = 4,962; df = 1; p = 0.026).
CONCLUSION
Our findings underscore the importance of attaining full remission of obsessive-compulsive symptoms during treatment and the need for new therapeutic strategies to achieve this.

A literature search was conducted to identify publications addressing the early phases of lipid phenotypes in children and adults with either type 1 diabetes or type 2 diabetes. Medline, EMBASE, and Ovid were searched using the following search terms: Partial clinical remission (PR) of type 1 diabetes (T1D) is characterized by continued endogenous production of insulin and C-peptide following the diagnosis and the introduction of exogenous insulin therapy. PR is associated with improved glycemic control and reduced prevalence of diabetes complications. The theory of hyperglycemic memory was proposed to explain this concept of improved glycemic outcomes in remitters (those who experienced PR) versus non-remitters (those who did not experience PR). However, this theory is incomplete as it does not explain the dichotomy in early lipid phenotypes in T1D based on PR status, which is an understudied area in diabetology and lipidology. To fill this knowledge gap, we propose the Theory of Hyperlipidemic Memory of T1D. This theory is premised on our 5-year research on early post-diagnostic dichotomy in lipid phenotypes between remitters and non-remitters across the lifespan. It provides a more rigorous explanation for the differences in lifelong atherosclerotic cardiovascular disease (ASCVD) risk between remitters and non-remitters. We conducted 4 clinical studies in pediatric and adult subjects with diabetes mellitus to characterize the particulars of the hyperlipidemic memory. In the first investigation, we explored the impact of the presence or absence of PR on lipid parameters in children and adolescents with T1D. In the second, we investigated whether pubertal maturation influenced our findings in T1D; and whether these findings could be replicated in healthy, non-diabetic children and adolescents. In the third, we leveraged our findings from T1D and controls to investigate the mechanisms of early lipid changes in T2D by comparing the earliest lipid phenotype of subjects with type 2 diabetes (T2D) to those of remitters, non-remitters, and controls. In the fourth, we investigated the impact of PR on the earliest lipid phenotypes in adults with T1D and compared these early lipid data to those of T2D subjects and controls. This body of work across the lifespan in children, adolescents, and adults supports the Theory of Hyperlipidemic Memory. This new theory clarifies why PR largely determines the risks for early-phase dyslipidemia, mid-term microvascular disease risk, and long-term ASCVD risk in subjects with T1D.

Comparative Study
A comparison of glycemic parameters and their relationship with C-peptide and Proinsulin levels during partial remission and non-remission periods in children with type 1 diabetes mellitus - a cross-sectional study.
BACKGROUND
Currently, there is a lack of data relating to glycemic parameters and their relationship with C-peptide (CP) and proinsulin (PI) during the partial remission period (PRP) in type 1 diabetes mellitus (T1D). The aim of this study was to evaluate glycemic parameters in children with T1D who are in the PRP using intermittently scanned continuous glucose monitoring systems (isCGMS) and to investigate any relationships between CP and PI levels.
METHODS
The study included 21 children who were in the PRP and 31 children who were not. A cross-sectional, non-randomized study was performed. Demographic, clinical data were collected and 2 week- isCGMS data were retrieved.
RESULTS
The Serum CP showed a positive correlation with time-in-range in the PRP (p:0.03), however PI showed no correlations with glycemic parameters in both periods. The Serum CP and PI levels and the PI:CP ratio were significantly higher in the PRP group than in the non-PRP group. In the non-PRP group, the PI level was below 0.1 pmol/L (which is the detectable limit) in only 2 of the 17 cases as compared with none in the PRP group. Similarly, only 2 of the 17 children in the non-PRP group had CP levels of less than 0.2 nmol / L, although both had detectable PI levels. Overall time-in-range (3. 9-1.0 mmol/L) was significantly high in the PRP group. In contrast, the mean sensor glucose levels, time spent in hyperglycemia, and coefficient of variation levels (32.2vs 40.5%) were significantly lower in the PRP group.
CONCLUSIONS
Although the mean glucose and time in range during the PRP was better than that in the non-PRP group, the glycemic variability during this period was not as low as expected. While the CP levels showed an association with TIR during the PRP, there was no correlation between PI levels and glycemic parameters. Further studies are needed to determine if PI might prove to be a useful parameter in clinical follow-up.

PURPOSE
We sought to evaluate features of partial remission (PR) in children with type 1 diabetes mellitus (T1DM) using the insulin-dose adjusted A1c (IDAA1c) definition and to identify risk factors associated with nonremission.
METHODS
Medical records of patients with newly diagnosed T1DM between January 1, 2008, and June 30, 2018, were retrospectively reviewed. Hemoglobin A1c (HbA1c) readings and insulin total daily doses (TDDs) of each patient at each follow-up visit were obtained with IDAA1c values calculated. PR was defined as an IDAA1c score of 9 points or less within 6 months of diagnosis. The trends of HbA1c and TDD within 2 years after diagnosis were compared between remitters and nonremitters. Factors that may predict the occurrence of PR were studied, with their relative risks of nonremission calculated.
RESULTS
PR occurred in 26 patients (45.6%), including 8 girls and 18 boys, with a median duration of 8 months. The frequency of remission in male patients was significantly higher (P=0.002) and the relative risk of female sex with nonremission was 2.20 (95% confidence interval [CI], 1.24-3.91), which remained significant when adjusted by multivariate regression modeling. The initial HbA1c level at diagnosis was also significantly higher in the nonremission group (P=0.029), with a relative risk of 1.12 (95% CI, 1.01-1.25). Both HbA1c (P=0.012) and TDD (P=0.006) were significantly lower within 2 years after diagnosis among remitters than in nonremitters. TDD was significantly lower in male patients (P=0.029) during the same period, while there was no significant difference in HbA1c level between male and female patients (P=0.163).
CONCLUSION
Both the initial HbA1c level at diagnosis and sex were factors associated with the occurrence of PR. Female sex was an independent risk factor of nonremission, likely resulting from a higher insulin requirement in female T1DM patients.

BACKGROUND
Conventional regimens for refractory idiopathic membranous nephropathy (IMN) still have limitations. Rituximab (RTX) has a good effect in the treatment of refractory IMN. However, whether RTX single or combined with immunosuppressive therapy is more effective and whether adverse events will increase are still inconclusive.
AIMS
To investigate the efficacy and safety of RTX combined with low-dose tacrolimus (TAC) versus RTX alone in the treatment of refractory IMN.
STUDY DESIGN
A retrospective cohort study.
METHODS
We retrospectively studied 91 cases of refractory IMN diagnosed between January 2018 and June 2021, all of which immunosuppressive regimens had failed. Thirty-four patients received RTX combined with TAC (RTX + TAC group), and 57 patients were treated with RTX alone (RTX group). The RTX + TAC group was given RTX 1 g once every 2 weeks, two times, and TAC 0.03 mg/kg/day orally. In the RTX group, RTX was given at the same dosage as the RTX + TAC group. Clinical data were collected at 12 months of follow-up to compare the complete and partial remission rates and the incidence of adverse reactions between the two groups.
RESULTS
The overall effectiveness rate of RTX + TAC in the treatment of refractory IMN was 87.14%, of which the partial and complete remission rates were 50.01% and 37.13%, respectively, and the median time to complete remission was 9 (interquartile range [IQR] 6.0, 12.0) months. The overall effectiveness rate of RTX was 65.87%, of which the partial and complete remission rates were 39.48% and 26.39%, respectively, and the median time to complete remission was 10.5 (IQR 6.0, 12.0) months. Adverse events occurred in 6 (17.65%) patients in the RTX + TAC group and in 11 (19.30%) in the RTX group ( = 0.473). Proteinuria and high titer of PLA2R are risk factors for non-remission.
CONCLUSION
The complete and partial remission rates of RTX combined with low-dose TAC in the treatment of refractory IMN are higher than those of RTX alone, and no significant increase in adverse events was noted.

OBJECTIVE To find a simple definition of partial remission in type 1 diabetes that reflects both residual beta-cell function and efficacy of insulin treatment. RESEARCH DESIGN AND METHODS A total of 275 patients aged <16 years were followed from onset of type 1 diabetes. After 1, 6, and 12 months, stimulated C-peptide during a challenge was used as a measure of residual beta-cell function. RESULTS By multiple regression analysis, a negative association between stimulated C-peptide and A1C (regression coefficient -0.21, P < 0.001) and insulin dose (-0.94, P < 0.001) was shown. These results suggested the definition of an insulin dose-adjusted A1C (IDAA1C) as A1C (percent) + [4 x insulin dose (units per kilogram per 24 h)]. A calculated IDAA1C < or =9 corresponding to a predicted stimulated C-peptide >300 pmol/l was used to define partial remission. The IDAA1C < or =9 had a significantly higher agreement (P < 0.001) with residual beta-cell function than use of a definition of A1C < or =7.5%. Between 6 and 12 months after diagnosis, for IDAA1C < or =9 only 1 patient entered partial remission and 61 patients ended partial remission, for A1C < or =7.5% 15 patients entered partial remission and 53 ended, for a definition of insulin dose < or =0.5 units . kg(-1) . 24 h(-1) 5 patients entered partial remission and 66 ended, and for stimulated C-peptide (>300 pmol/l) 9 patients entered partial remission and 49 ended. IDAA1C at 6 months has good predictive power for stimulated C-peptide concentrations after both 6 and 12 months. CONCLUSIONS A new definition of partial remission is proposed, including both glycemic control and insulin dose. It reflects residual beta-cell function and has better stability compared with the conventional definitions.

Membranous nephropathy (MN) is an immune-mediated glomerular disease that can lead to nephrotic syndrome and progressive kidney function loss. The cyclic steroid-cyclophosphamide regimen (the modified Ponticelli protocol) and the monoclonal anti-CD20 antibody rituximab have been advocated as effective therapies to improve renal outcomes, but a direct comparison of these treatments had never been carried out in a prospective study. Subject of Review: Scolari et al. [J Am Soc Nephrol. 2021;32:972-82] recently reported the results of a pilot randomized controlled trial (RI-CYCLO) designed to provide direct estimates of the effect of rituximab (1 g × 2) compared to the cyclic steroid-cyclophosphamide regimen in 74 patients with MN. The proportion of patients with complete remission at 12 months was higher in the cyclic regimen arm than that of rituximab (32 and 16%, respectively), but the difference was not statistically significant in intention-to-treat analyses. Interestingly, differences in the cumulative incidence of complete and partial remissions between treatment arms progressively reduced over the follow-up and became virtually nonexistent from 24 months (>80% in both groups). The frequency of serious and nonserious adverse events was similar between the 2 treatment arms. Infusion reactions and drug discontinuation were more common with rituximab, while infections and leukopenia were more frequently observed with the cyclic regimen. The risk of cancer was similar in the 2 allocation groups, but the limited follow-up length did not allow to draw definitive conclusions. Independent of treatment allocation, 18% of patients experienced at least 1 relapse after achieving complete or partial remission. Second Opinion: Notwithstanding the intrinsic limitations of a pilot study, the RI-CYCLO trial represents an important milestone in the treatment of MN. Findings from this study support the hypothesis that the cyclic regimen and rituximab may have comparable efficacy in inducing disease remission over the long term. Considering its potentially better-albeit not yet formally proven-long-term safety profile, rituximab could be considered as a first-line therapy for most patients with MN. Several questions remain to be addressed, including rituximab ideal dose and its efficacy in patients with a significant reduction in glomerular filtration rate. In light of RI-CYCLO results, a large-scale trial to assess rituximab noninferiority to the cyclic regimen would require the enrollment of thousands of patients, and it would be probably unfeasible within a reasonable time frame. In our opinion, resources should be allocated to provide an answer to the pressing matter of treatment nonresponse and intolerance, which may be addressed in the near future with novel therapeutic strategies.

(1) Background: We sought to investigate the clinical outcome and to identify the independent predictors of clinical remission in a prospectively followed cohort of patients with primary membranous nephropathy (pMN). (2) Methods: We conducted a prospective, observational, non-interventional study that included 65 consecutive patients diagnosed with pMN between January 2015 and December 2019 at our department and followed for at least 24 months. The primary outcomes evaluated during the follow-up period were the occurrence of immunological and clinical remission (either complete or partial remission). Univariate and multivariate Cox proportional hazard regression analyses were performed to identify independent predictors of clinical remission. (3) Results: In the study cohort, 13 patients had a PLA2R-negative pMN, while, of those with PLA2R-associated pMN, 27 patients had a low anti-PLA2R antibody titer (<200 RU/mL), and 25 patients had a high anti-PLA2R antibody titer at baseline (≥200 RU/mL). The clinical outcome was better in patients with PLA2R-negative pMN compared to patients with PLA2R-positive pMN. These patients had a higher percentage of complete remissions (46.2%, compared to 33.3% in those with low anti-PLA2R antibody titer or 24% in those with high anti-PLA2R antibody titer), a faster decline of 24 h proteinuria and lower time to complete remission. In multivariate Cox regression analysis, patients with PLA2R-negative pMN had a 3.1-fold and a 2.87-fold higher chance for achieving a complete or partial remission compared to patients with high anti-PLA2R antibody titer or to all PLA2R-positive patients, respectively. Additionally, patients with a baseline 24 h proteinuria of less than 8 g/day and with an immunological remission at 24 months had a 2.4-fold (HR, 2.4; 95%CI, 1.19-4.8) and a 2.2-fold (HR, 2.26; 95%CI, 1.05-4.87), respectively, higher chance of achieving a clinical response. By contrary, renal function at diagnosis, type of therapeutic intervention or anti-PLA2R antibody titer did not predict the occurrence of clinical remission. (4) Conclusions: We identified a different clinical phenotype between PLA2R-positive and PLA2R-negative pMN. Additionally, we have shown that baseline proteinuria seems to be a more important predictor of clinical outcome than anti-PLA2R-ab titer.
