Meta-Analysis
AIMS
To compare the safety and efficacy of insulin detemir versus neutral protamine Hagedorn (NPH) in pregnant women with diabetes.
METHODS
MEDLINE, CENTRAL, Google Scholar databases, and ClinicalTrials.gov registry were searched from inception to December 2021 to identify randomized controlled trials (RCTs) concerning adult women with singleton pregnancies, gestational or pregestational diabetes, and the need for insulin therapy. A systematic review and a meta-analysis (weighted data, random-effects model) were performed. Continuous outcomes were expressed as mean difference (MD) with 95% confidence interval (CI) (inverse variance method); dichotomous outcomes were expressed as risk ratio (RR) with 95% CI (Mantel-Haenszel method). Heterogeneity was quantified using the I index.
RESULTS
Five RCTs involving 1450 participants met the inclusion criteria. Outcomes that showed significant results in favor of insulin detemir over NPH were maternal hypoglycemic events (RR 0.64, 95% CI 0.48-0.86, p = 0.003; I = 0%) and gestational age at delivery (MD 0.48, 95% CI 0.16-0.81, p = 0.003; I = 0%).
CONCLUSIONS
Insulin detemir was associated with less maternal hypoglycemic events and decreased risk for prematurity compared with NPH insulin. More research should be conducted to reach a safe conclusion about the optimal insulin regimen for women with diabetes in pregnancy.

Review
(1) Background: Systemic mastocytosis is a rare, non-curable disease with potential life-threatening complications in patients receiving cardiac surgery. (2) Methods: This systematic review of the literature was prompted by the case of a life-threatening anaphylactic reaction during cardiac surgery related to systemic mastocytosis. The search of all types of studies, using several databases (Pubmed, Scopus and Web of Science), was conducted through September 2022 to identify the relevant studies. (3) Results: Twelve studies were included describing cases of patients undergoing cardiac surgery who were diagnosed with systemic mastocytosis. An adverse effect, namely anaphylaxis, has happened in three cases. Different strategies of premedication, intraoperative and postoperative management were used. In our case, the patient was admitted for elective biological aortic valve replacement due to severe aortic stenosis. Intraoperatively, the patient developed an anaphylactic shock during the administration of protamine after separation from the cardiopulmonary bypass. This anaphylaxis reaction was a complication of the pre-existing systemic mastocytosis and could be successfully managed by the administration of epinephrine, antihistamines and corticosteroids. (4) Conclusions: This systematic literature search and case report highlight the importance of careful preoperative planning, as well as coordination between cardiac surgeons, anesthesiologists and hemato-oncological specialists, in patients with rare but complication-prone diseases such as systemic mastocytosis.

Review
The objective of this study was to provide recommendations regarding effectiveness, safety, optimal starting dose, optimal maintenance dose range, and target fasting plasma glucose of five basal insulins (glargine U-300, degludec U-100, glargine U-100, detemir, and insulin protamine Hagedorn) in insulin-naïve adult patients with type 2 diabetes in the Asia-Pacific region. Based on evidence from a systematic review, we developed an Asia-Pacific clinical practice guideline through comprehensive internal review and external review processes. We set up and used clinical thresholds of trivial, small, moderate, and large effects for different critical and important outcomes in the overall certainty of evidence assessment and balancing the magnitude of intervention effects when making recommendations, following GRADE methods (Grading of Recommendations, Assessment, Development, and Evaluation). The AGREE (Appraisal of Guidelines, Research and Evaluation) and RIGHT (Reporting Items for practice Guidelines in HealThcare) guideline reporting checklists were complied with. After the second-round vote by the working group members, all the recommendations and qualifying statements reached over 75% agreement rates. Among 44 contacted external reviewers, we received 33 clinicians' and one patient's comments. The overall response rate was 77%. To solve the four research questions, we made two strong recommendations, six conditional recommendations, and two qualifying statements. Although the intended users of this guideline focused on clinicians in the Asia-Pacific region, the eligible evidence was based on recent English publications. We believe that the recommendations and the clinical thresholds set up in the guideline can be references for clinicians who take care of patients with type 2 diabetes worldwide.

Annals of Internal Medicine Aug 2018Basal insulin analogues aim for protracted glycemic control with minimal adverse effects. (Meta-Analysis)
Meta-Analysis
BACKGROUND
Basal insulin analogues aim for protracted glycemic control with minimal adverse effects.
PURPOSE
To assess the comparative efficacy and safety of basal insulin analogues for adults with type 2 diabetes mellitus (T2DM).
DATA SOURCES
Several databases from inception to April 2018 without language restrictions, ClinicalTrials.gov to April 2018, references of reviews, and meeting abstract books.
STUDY SELECTION
Randomized trials lasting at least 12 weeks that compared efficacy (change in hemoglobin A1c [HbA1c] level from baseline [primary outcome]; percentage of patients with HbA1c level <7% at end of study and change in body weight [secondary outcomes]) and safety (hypoglycemia) of basal insulin analogues.
DATA EXTRACTION
Two authors independently extracted data and assessed risk of bias for each outcome. All authors evaluated overall confidence in the evidence.
DATA SYNTHESIS
Thirty-nine trials (26 195 patients) assessed 10 basal insulin analogues. Low- to very-low-quality evidence indicated that thrice-weekly degludec (Deg-3TW) was inferior to most other regimens for reducing HbA1c level, with mean differences ranging from 0.21% (vs. degludec, 100 U/mL [Deg-100]) to 0.32% (vs. glargine, 300 U/mL [Glar-300]). High- to moderate-quality evidence suggested that detemir had a favorable weight profile versus all comparators, and Glar-300 was associated with less weight gain than glargine, 100 U/mL (Glar-100); Deg-100; degludec, 200 U/mL (Deg-200); Deg-3TW; and LY2963016. Low- and very-low-quality evidence suggested that Deg-100, Deg-200, and Glar-300 were associated with lower incidence of nocturnal hypoglycemia than detemir, Glar-100, LY2963016, and neutral protamine lispro (NPL). Incidence of severe hypoglycemia did not differ among regimens, except NPL, which was associated with increased risk versus Deg-100, detemir, Glar-100, and Glar-300.
LIMITATIONS
Results are based mostly on indirect comparisons. Confidence in summary estimates is low or very low due to individual-study limitations, imprecision, or inconsistency.
CONCLUSION
Low-quality evidence suggests that basal insulin analogues for T2DM do not substantially differ in their glucose-lowering effect. Low- and very-low-quality evidence suggests some regimens may be associated with lower risk for nocturnal hypoglycemia (Deg-100, Deg-200, and Glar-300) or less weight gain (detemir and Glar-300).

INTRODUCTION
The use of insulin analogs for the treatment of type 1 diabetes mellitus (T1DM) is widespread; however, the therapeutic benefits still require further evaluation given their higher costs. The objective of this study was to evaluate the effectiveness and safety of analog insulin glargine compared to recombinant DNA (rDNA) insulin in patients with T1DM in observational studies, building on previous reviews of randomized controlled trials comparing neutral protamine Hagedorn insulin and insulin glargine.
METHODS
A systematic review with a meta-analysis was performed. The review included cohort studies and registries available on PubMed, LILACS, and the Cochrane Central Register of Controlled Trials (CENTRAL), as well as manual and gray literature searches. The meta-analysis was conducted in Review Manager 5.3 software. The primary outcomes were glycated hemoglobin (Hb1Ac), weight gain, and hypoglycemia. Methodological quality was assessed using the Newcastle-Ottawa scale.
RESULTS
Out of 796 publications, 11 studies were finally included. The meta-analysis favored insulin glargine in HbA1c outcomes (adult patients) and hypoglycemic episodes (P < 0.05), but without reaching glycemic control (Hb1Ac to approximately 7%). The methodological quality of the studies was moderate, noting that 45% of studies were funded by pharmaceutical companies.
CONCLUSION
Given the high heterogeneity of the studies, the discrete value presented by the estimated effect on effectiveness and safety, potential conflicts of interest of the studies, and the appreciable higher cost of insulin glargine, there is still no support for recommending first-line therapy with analogs. The role of analogs in the treatment of T1DM could be better determined by further observational studies of good methodological quality to assess their long-term effectiveness and safety, as well as their cost-effectiveness.

Meta-Analysis
STUDY OBJECTIVE
Activated clotting time (ACT) is a non-specific test to evaluate the adequacy of systemic heparinization whose value could be influenced by many factors. Tranexamic acid (TXA) is a widely used antifibrinolytic agent worldwide and whether TXA influences ACT value in cardiac surgical patients remains unknown. Current study was performed to address this question.
DESIGN
Systematic review and meta-analysis. PUBMED, Cochrane Library, EMBASE, OVID and Chinese BioMedical Literature & Retrieval System were searched using search terms "tranexamic acid", "activated clotting time", "cardiac surgery", "randomized controlled trial" till May 7th, 2020, to identify all relevant randomized controlled trials (RCTs).
SETTING
Operating room.
PATIENTS
Cardiac surgical patients.
INTERVENTIONS
TXA or placebo.
MEASUREMENTS
Primary outcomes of interest included peri-operative ACT values. Secondary outcomes of interest include heparin dosage, protamine dosage, postoperative bleeding and blood transfusion.
MAIN RESULTS
Search yielded 13 studies including 1168 patients, and 619 patients were allocated into Group TXA and 549 into Group Control (placebo). Meta-analysis suggested that, ACT values after heparinization [(WMD = -1.45; 95%CI: -12.52 to 15.43; P = 0.84)] and after protamine [(WMD = -1.18; 95%CI: -2.81 to 0.46; P = 0.16)] were comparable between Group TXA and Group Control, and that TXA did not influence heparin dose in adult patients [(WMD = 0.38; 95%CI: 0.30 to 0.46; P<0.00001) with no heterogeneity (I = 4%, P = 0.35)] and protamine dose for heparin reversal [(WMD = 5.23; 95%CI: -0.33 to 10.80; P = 0.07) with no heterogeneity (I = 0, P = 0.58)]. Meta-analysis also demonstrated that, TXA administration significantly reduced post-operative bleeding volume [(WMD = -126.33; 95%CI: -177.46 to -75.19; P < 0.0001), post-operative red blood cell (RBC) transfusion volume [(WMD = -71.86; 95% CI: -88.22 to -55.50; P < 0.00001), fresh frozen plasma (FFP) transfusion volume [(WMD = -13.83; 95% CI: -23.67 to -4.00; P = 0.006) and platelet concentrate (PC) transfusion volume [(WMD = -0.20; 95% CI: -0.29 to -0.10; P < 0.0001).
CONCLUSION
This meta-analysis suggested that, TXA administration did not influence ACT value, heparin and protamine doses, but significantly reduced post-operative blood loss and transfusion requirement in cardiac surgical patients.

Comparative Study Meta-Analysis Review
INTRODUCTION
Although numerous studies showed an improvement in glycemic control in type 1 diabetic patients treated with long-acting insulin analogue detemir compared with Neutral Protamine Hagedorn (NPH) insulin, the beneficial effects of insulin detemir has not been confirmed by all investigators.
OBJECTIVES
The aim of the study was to compare the effect of treatment with detemir insulin vs. NPH insulin on metabolic control, hypoglycemic episodes, and body weight gain in patients with type 1 diabetes by means of a systematic review and a meta-analysis.
METHODS
The following electronic databases were searched up to November 2010: MEDLINE, EMBASE, and the Cochrane Library. Additional references were obtained from the reviewed articles. Only randomized controlled trials of at least 12-week duration with basal-bolus regimen therapies using detemir insulin vs. NPH insulin were included.
RESULTS
The analysis included 10 studies involving 3825 patients with type 1 diabetes. Combined data from all trials showed a statistically significant reduction in hemoglobin A1c (HbA1c) (weighted mean difference: [WMD] -0.073, 95% CI -0.135 to -0.011, P = 0.021) in the detemir group compared with the NPH group. There was also a significant reduction of fasting plasma glucose (FPG) (WMD - 0.977 mmol/l, 95% CI -1.395 to -0.558, P <0.001), all-day hypoglycemic episodes (relative risk [RR] 0.978, 95% CI 0.961-0.996), severe hypoglycemic episodes (RR 0.665, 95% CI 0.547-0.810), nocturnal hypoglycemic episodes (RR 0.877, 95% CI 0.816-0.942), as well as smaller body weight gain (WMD -0.779 kg, 95% CI -0.992 to -0.567) in patients using detemir insulin compared with those using NPH insulin.
CONCLUSIONS
Basal-bolus treatment with insulin detemir, as compared with NPH insulin, provided a minor benefit in terms of the HbA1c value and significantly reduced FPG in type 1 diabetic patients. Treatment with detemir insulin was also superior to NPH insulin in reducing the risk of all-day, nocturnal, and severe hypoglycemic episodes, with the added benefit of reduced weight gain.

INTRODUCTION
While pulmonary arterial hypertension remains an uncommon diagnosis, various therapeutic agents are recognized as important associations. These agents are typically categorized into "definite", "likely", "possible", or "unlikely" to cause pulmonary arterial hypertension, based on the strength of evidence.
OBJECTIVE
This review will focus on those therapeutic agents where there is sufficient literature to adequately comment on the role of the agent in the pathogenesis of pulmonary arterial hypertension.
METHODS
A systematic search was conducted using PubMed covering the period September 1970- 2017. The search term utilized was "drug induced pulmonary hypertension". This resulted in the identification of 853 peer-reviewed articles including case reports. Each paper was then reviewed by the authors for its relevance. The majority of these papers (599) were excluded as they related to systemic hypertension, chronic obstructive pulmonary disease, human immunodeficiency virus, pulmonary fibrosis, alternate differential diagnosis, treatment, basic science, adverse effects of treatment, and pulmonary hypertension secondary to pulmonary embolism. Agents affecting serotonin metabolism (and related anorexigens): Anorexigens, such as aminorex, fenfluramine, benfluorex, phenylpropanolamine, and dexfenfluramine were the first class of medications recognized to cause pulmonary arterial hypertension. Although most of these medications have now been withdrawn worldwide, they remain important not only from a historical perspective, but because their impact on serotonin metabolism remains relevant. Selective serotonin reuptake inhibitors, tryptophan, and lithium, which affect serotonin metabolism, have also been implicated in the development of pulmonary arterial hypertension. Interferon and related medications: Interferon alfa and sofosbuvir have been linked to the development of pulmonary arterial hypertension in patients with other risk factors, such as human immunodeficiency virus co-infection. Antiviral therapies: Sofosbuvir has been associated with two cases of pulmonary artery hypertension in patients with multiple risk factors for its development. Its role in pathogenesis remains unclear. Small molecule tyrosine kinase inhibitors: Small molecule tyrosine kinase inhibitors represent a relatively new class of medications. Of these dasatinib has the strongest evidence in drug-induced pulmonary arterial hypertension, considered a recognized cause. Nilotinib, ponatinib, carfilzomib, and ruxolitinib are newer agents, which paradoxically have been linked to both cause and treatment for pulmonary arterial hypertension. Monoclonal antibodies and immune regulating medications: Several case reports have linked some monoclonal antibodies and immune modulating therapies to pulmonary arterial hypertension. There are no large series documenting an increased prevalence of pulmonary arterial hypertension complicating these agents; nonetheless, trastuzumab emtansine, rituximab, bevacizumab, cyclosporine, and leflunomide have all been implicated in case reports. Opioids and substances of abuse: Buprenorphine and cocaine have been identified as potential causes of pulmonary arterial hypertension. The mechanism by which this occurs is unclear. Tramadol has been demonstrated to cause severe, transient, and reversible pulmonary hypertension. Chemotherapeutic agents: Alkylating and alkylating-like agents, such as bleomycin, cyclophosphamide, and mitomycin have increased the risk of pulmonary veno-occlusive disease, which may be clinically indistinct from pulmonary arterial hypertension. Thalidomide and paclitaxel have also been implicated as potential causes. Miscellaneous medications: Protamine appears to be able to cause acute, reversible pulmonary hypertension when bound to heparin. Amiodarone is also capable of causing pulmonary hypertension by way of recognized side effects.
CONCLUSIONS
Pulmonary arterial hypertension remains a rare diagnosis, with drug-induced causes even more uncommon, accounting for only 10.5% of cases in large registry series. Despite several agents being implicated in the development of PAH, the supportive evidence is typically limited, based on case series and observational data. Furthermore, even in the drugs with relatively strong associations, factors that predispose an individual to PAH have yet to be elucidated.

OBJECTIVES
Heparin has a non-predictable effect in the individual patient. The activated clotting time (ACT) is used to measure the level of anticoagulation after administration of heparin. To date, appropriate heparin dose protocols and corresponding therapeutic ACT values have not been established in non-cardiac arterial procedures (NCAP). The aim of this review was to study the use of ACT monitoring during NCAP, and whether an optimal ACT could be determined based on the fewest arterial thrombo-embolic complications (ATEC) and bleeding complications.
METHODS
This systematic review was performed in accordance with the PRISMA Guidelines. A systematic search was conducted in MEDLINE, EMBASE, and the Cochrane database. Any associations were evaluated between peri-procedural ACT levels and ATEC and bleeding complications detected during the same admission as the primary procedure or during 30 day follow up. Also, heparin dose protocols, peri-procedural target ACTs, different ACT devices, protamine use and pre-, peri-, and post-procedural anticoagulation therapy were evaluated.
RESULTS
In total, 21 studies with 3982 patients were included, on both open and endovascular NCAP. Four studies were primarily designed to correlate peak peri-procedural ACT with clinical outcomes; however, the definitions of the results and the clinical outcomes were too heterogeneous for analysis. There was major variability in all studied aspects of ACT measurement, heparin and protamine use, and in the type of procedures in the included studies. Overall methodological quality of the included studies was poor. No randomised controlled trials were found. Studies were at a high risk of bias.
CONCLUSIONS
This systematic review demonstrates a lack of data and no consensus in the literature concerning the optimal ACT, and the possible association with haemorrhagic complications and ATEC during NCAP.

The nuclear lamina (NL) is a filamentous protein meshwork, composed essentially of lamins, situated between the inner nuclear membrane and the chromatin. The NL is a component of the nuclear envelope, interacts with a wide range of proteins and is required for normal nuclear structure and physiological development. During spermiogenesis the spermatid nucleus is elongated, and dramatically reduced in size with protamines replacing histones to produce a highly compacted chromatin. There is mounting evidence from studies in human and rodent, that the NL plays an important role in mammalian spermatid differentiation during spermiogenesis. In this review, we summarize and discuss the data available in the literature regarding the involvement of lamins and their direct or indirect partners in normal and abnormal human spermiogenesis.
