This paper reviews the risk of thrombosis with use of different types of hormonal contraception in women of different ages. ⋯ First choice in women below 35 years should be a combined low-risk pill, that is, with a second-generation progestin, with the lowest compliable dose of estrogen. Young women with risk factors of thrombosis such as age above 35 years, genetic predispositions, adiposity, polycystic ovary syndrome, diabetes, smoking, hypertension or migraine with aura should not use high-risk products, but should primarily consider progestin-only products, and be careful to use low-risk combined products.

Review5-Hydroxytryptamine3 receptor antagonists and cardiac side effects.
5-Hydroxytryptamine3-receptor antagonists (5-HT3-RA) are the most widely used antiemetics in oncology, and although tolerability is high, QTC prolongation has been observed in some patients. ⋯ Most of the studies analyze electrocardiogram (ECG) changes after 5-HT3-RA administrations in healthy, young adults, or in noncancer patients to treat postoperative nausea and vomiting (PONV). Only a few studies have addressed ECG changes in cancer patients treated for chemotherapy-induced nausea and vomiting (CINV). Investigations in cancer patients are essential, because these patients are older and have a higher incidence of comorbidity, than those usually included in clinical trials. Furthermore, polypharmacy is frequent and drug-drug interactions between chemotherapy and other QTc-prolonging drugs may influence the pharmacokinetics and pharmacodynamics of the 5-HT3-RAs. During the next 10 - 15 years a huge increase in the number of cancer patients is expected, primarily in the group of 65-plus-year old. Therefore it will be crucial to address the incidence of cardiac AEs in cancer patients with known heart disease receiving chemotherapy and a 5-HT3 RA for the prophylaxis of CINV.

Review Comparative StudySexual dysfunction associated with major depressive disorder and antidepressant treatment.
There is a well-established relationship between sexual functioning and quality of life. Depression can cause sexual dysfunction (SD) and its treatment can often lead to restoration of sexual functioning. Use of antidepressants has also been associated with SD, with implications for treatment compliance and creation of further distress for the patient. ⋯ Depression and SD have a bidirectional association. When screening for depression, baseline sexual functioning should be assessed with validated rating scales. If sexual side effects develop with antidepressant treatment, management options include waiting for spontaneous remission, decreasing the medication dose, switching to an alternative drug or adding an augmentation agent or antidote. Research suggests that bupropion and newer antidepressants exhibit a more favorable SD profile compared with other antidepressants, especially selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors. Bupropion, mirtazapine and buspirone have been studied as augmentation agents/antidotes or substitution agents in management of AASD. Future studies validating genetic factors could enable personal genotyping to guide individualized treatment and also facilitate the development of enhanced therapeutic guidelines to avoid or manage AASD.

Review Meta AnalysisA drug safety evaluation of rituximab and risk of hepatitis B.
Rituximab is a widely prescribed anti-CD20 mAb for the treatment of CD20(+) B-cell non-Hodgkin Lymphoma and many other immune mediated conditions. There is a well-described association between rituximab containing chemo-immunotherapy treatment and reactivation of the hepatitis B virus (HBV). This review summarizes the current literature surrounding rituximab-associated HBV reactivation. ⋯ Screening should be performed in all patients prior to the administration of any type of anti-CD20 mAb therapy. Among those with positive screening serology, testing for hepatitis B e antigen or viral load by polymerase chain reaction is appropriate. In those patients with detectable HBV DNA, the decision regarding the use of antiviral prophylaxis or observation should be individualized.

Review Comparative StudyDrug safety evaluation of naltrexone/bupropion for the treatment of obesity.
Obesity is a known health risk for the development of several preventable diseases. Obesity-related metabolic alterations negatively impact different physiological mechanisms, which supports the rationale for the use of combined drug therapy. Naltrexone is an opioid antagonist for the treatment of opioid and alcohol dependency, whereas bupropion is a norepinephrine/dopamine reuptake inhibitor used to treat depression and smoking cessation. Although not effective as individual monotherapies for obesity, naltrexone and bupropion in combination produce weight loss and a metabolic profile beneficial for the potential treatment of obesity. ⋯ Naltrexone/bupropion has a greater weight loss efficacy than two FDA-approved medications, orlistat and lorcaserin. Although the weight loss produced by phentermine/topiramate is superior to naltrexone/bupropion, the safety profile of naltrexone/bupropion has less severe adverse effects. In addition, naltrexone/bupropion is well tolerated, with nausea being the most reported adverse event. Unlike other centrally acting medications, lorcaserin and phentermine/topiramate, naltrexone/bupropion has no abuse potential.
