RESUMO

Long COVID, which is characterised by the presence of persistent symptoms following a COVID infection, may also cause long COVID depression (LCD). Although the risk factors for LCD are not directly characterised, prior mental health visits were associated with an increased risk for long COVID, whereas antidepressant use was not. Current evidence suggests that pro-inflammatory factors in the brain are linked to LCD, thus anti-inflammatory agents may be useful in mitigating LCD. Limited evidence suggests that selective serotonin reuptake inhibitors may also be effective in the treatment of LCD.

RESUMO

Cancer vaccines have been developed as an additional method of treatment in the fight against cancer. However, an important barrier to an effective vaccine is the inefficient presentation of exogenous antigen by dendritic cells to cytotoxic CD8 T cells. In this study, DPPC liposomes were modified with channels and loaded with polyethyleneimine (PEI) and 5,6-dimethylxanthenone-4-acetic acid (DMXAA) to produce a vaccine carrier. The liposomes were designed to be pH responsive to facilitate delivery of antigens directly to the cytoplasm of antigen presenting cells, bypassing the cross-presentation pathway and improving cellular immune responses. The lysis of liposomes in acidic cell-free conditions was measured using a validated dynamic light scattering assay in order to gain an insight into the mechanism of PEI-mediated lysis. Dendritic cell stimulation and T cell proliferation was investigated in vitro and the potential of this formulation to stimulate a therapeutic anti-cancer immune response was examined in a murine melanoma model. The modified formulation stimulated T cell activation in vitro and induced a small but significant increase in survival in immunized mice. Overall, liposomes modified with PEI and channels successfully delivered antigen to the cytoplasm of dendritic cells, which subsequently led to the development of an appropriate immune response.

RESUMO

mRNA vaccines are considered to be important tools for the management of the COVID-19 pandemic. Although mRNA COVID-19 vaccines are well tolerated in most recipients, post-marketing data have highlighted an association between myocarditis and mRNA vaccines. Post-vaccine myocarditis (PVM) is most commonly reported in male adolescents receiving the second dose of an mRNA vaccine. However, the incidence of PVM is low and the risk of myocarditis should be kept in perspective. Cases of PVM are mostly mild in severity, and may be managed using existing myocarditis guidelines. The pathology of PVM is under investigation, and current data suggest that cross reactivity or hypersensitivity reactions may be involved. Globally, mRNA vaccines are generally recommended for use in children/adolescents, and delaying the administration of the second dose may reduce the risk of PVM.

RESUMO

BACKGROUND: Patients with schizophrenia need continuous integrated healthcare, but many discontinue their treatment, often experiencing adverse outcomes. The first objective of this study is to assess whether patient characteristics or treatment history are associated with discontinuity of psychiatric elective care. The second objective is to assess whether practice variation between providers of psychiatric care contributes to discontinuity of elective care. METHODS: A large registry-based retrospective cohort of 9194 schizophrenia patients, who were included if they received elective psychiatric care in December 2014-January 2015. Logistic regression models were used to identify predictive factors of discontinuity of care. The dependent variable was the binary variable discontinuity of care in 2016. Potential independent predictive variables were: age, sex, urbanization, and treatment history in 2013-2014. Practice variation between providers was assessed, adjusting for the case mix of patients regarding their demographic and care utilization characteristics. RESULTS: 12.9% of the patients showed discontinuity of elective psychiatric care in the follow-up year 2016. The risk of discontinuity of care in 2016 was higher in younger patients (between age 18 and 26), patients with a history of receiving less elective psychiatric care, more acute psychiatric care, more quarters with elective psychiatric care without antipsychotic medication, or receiving no elective treatment at all. No evidence for practice variation between providers was found. CONCLUSIONS: Our findings show that the pattern of previous care consumption is an important prognostic factor of future discontinuity of elective care. We propose that previous care consumption can be used to design strategies to improve treatment retention and focus resources on those most at risk of dropping out.

RESUMO

BACKGROUND: To explore changes in utilization patterns for general practice (GP) and hospital care of people living in deprived neighbourhoods when primary care providers work in a more coherent and coordinated manner by applying an integrated approach. METHODS: We compared expected (based on consumption patterns of a health insurers' total population) and actual utilization patterns in a deprived Dutch intervention district in the city of Utrecht (Overvecht) with control districts 1 (Noordwest) and 2 (Kanaleneiland) over the period 2006-2011, when an integrated care approach was increasingly provided in the intervention district. Standardized insurance claims data were used to indicate use of GP care and hospital care. RESULTS: Our findings revealed that the utilization of total GP care increased more in the intervention district than in the control districts. And that the intervention district showed a more pronounced decreasing trend in total hospital use as compared to what was expected, in particular from 2008 onwards. In addition, we observed a change in type of GP care use in the intervention district in particular: the number of regular consultations, long consultations, GP home visits and evening, night and weekend consultations were increasingly higher than expected. The intervention district also showed the largest decrease between actual and expected use of ambulatory care, clinical care and 1-day hospitalizations. CONCLUSIONS: Utilization patterns for general practice and hospital care of people living in deprived districts may change when primary care professionals work in a more coherent and coordinated manner by applying a more 'comprehensive' integrated care approach. Results support the expectation that a comprehensive integrated care approach might eventually contribute to the future sustainability of healthcare systems.

RESUMO

BACKGROUND: Patients with bipolar disorder benefit from guidelines recommended continuous community-oriented psychiatric and somatic healthcare, but often discontinue psychiatric care. AIMS: The first objective was to identify predictive factors of discontinuity of psychiatric care among patients who had received psychiatric care. The second objective was to examine if practice variation in discontinuity of psychiatric care existed between providers of psychiatric care. METHOD: Registry healthcare data were used in a retrospective cohort study design using logistic regression models to examine potential predictive factors of discontinuity of care. Patient-related predictive factors were: age, sex, urbanization, and previous treatment (type and amount of psychiatric care, alcohol, and opioid treatment). Patients already diagnosed with bipolar disorder were selected if they received psychiatric care in December 2014 to January 2015. Discontinuity of psychiatric care was measured over 2016. RESULTS: A total of 2,355 patients with bipolar disorder were included. In 12.1% discontinuity of care occurred in 2016. Discontinuity was associated with younger age and less outpatient care over 2013 to 2014. Discontinuity of patients who received all eight quarters outpatient care including BD medication was very low at 4%. The final model contained: age, type of psychiatric care, and amount of outpatient care in 2013 to 2014. Practice variation among providers appeared negligible. CONCLUSIONS: The (mental) health service in the Netherlands has few financial or other barriers toward continuity of care for patients with severe mental disorders, such as bipolar disorder. An active network of providers, aim to standardize care. This seems successful. However, 12% discontinuity per year remains problematic and more detailed data on those most at risk to drop out of treatment are necessary.

RESUMO

Ublituximab (ublituximab-xiiy; BRIUMVI™) is a glycoengineered anti-CD20 monoclonal antibody developed by TG Therapeutics, Inc. for the treatment of multiple sclerosis (MS). The mechanism of action of ublituximab involves the depletion of B cells via antibody-dependent cellular cytotoxicity, as B cells have a key role in the pathogenesis of MS. Ublituximab is the first anti-CD20 treatment that is administered twice-yearly as one hour infusions, following the initial doses. In December 2022, ublituximab received its first global approval in the USA for the treatment of adults with relapsing forms of MS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. This article summarizes the milestones in the development of ublituximab leading to this first approval in this indication.

RESUMO

Nadofaragene firadenovec (nadofaragene firadenovec-vncg; Adstiladrin®) is a non-replicating adenoviral vector-based gene therapy developed by Ferring Pharmaceuticals for the treatment of high-risk Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC). Nadofaragene firadenovec constitutes vector DNA that encodes for interferon (IFN)-α2b and is the first approved gene therapy in bladder cancer. The production of IFN-α2b by transfected urothelial cells is associated with anticancer activity, including immunostimulatory, antiangiogenic and apoptotic effects. In December 2022, nadofaragene firadenovec received its first global approval in the USA for the treatment of high-risk BCG-unresponsive NMIBC with carcinoma in situ (CIS) with or without papillary tumours in adults. This article summarizes the milestones in the development of nadofaragene firadenovec leading to this first approval for this indication.

RESUMO

Omaveloxolone (SKYCLARYS™) is an orally active, small molecule semi-synthetic triterpenoid drug that increases antioxidant activity, which is being developed by Reata Pharmaceuticals, Inc. for the treatment of Friedreich's ataxia. In patients with Friedreich's ataxia, the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway is suppressed, which is associated with oxidative stress, mitochondrial dysfunction and damage to cells, including central and peripheral neurones. The Nrf2 pathway may be activated by omaveloxolone as it blocks the ubiquitination and degradation of Nrf2. Omaveloxolone was approved in February 2023 in the USA for the treatment of Friedreich's ataxia. This article summarizes the milestones in the development of omaveloxolone leading to this first approval for the treatment of Friedreich's ataxia in adults and adolescents aged 16 years and older.

RESUMO

Darolutamide (NUBEQA®) is an oral androgen receptor inhibitor (ARi) that is approved for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC) in combination with androgen deprivation therapy (ADT) and docetaxel. In a pivotal trial, darolutamide plus ADT and docetaxel was superior to placebo plus ADT and docetaxel in prolonging the primary endpoint of overall survival, with improvements also reported in most secondary endpoints. Treatment with darolutamide plus ADT and docetaxel was associated with a manageable tolerability profile. Furthermore, the adverse events reported with darolutamide plus ADT and docetaxel were generally consistent with the safety profiles previously reported for ADT and docetaxel. Darolutamide expands the availability of treatment options in mHSPC and may be useful as a treatment for high-volume disease (typically defined as ≥ 4 bone metastases with spread outside of the pelvis and vertebral column).


Prostate cancer is the second and fourth most diagnosed cancer in the USA and Europe, respectively. Distant metastases are detected in 8% of patients at initial presentation and are associated with poorer 5-year survival rates in comparison to patients with localised or regional disease. Historically, patients with metastatic hormone-sensitive prostate cancer (mHSPC) were treated with androgen deprivation therapy (ADT). More recently, patients have been treated with ADT plus either docetaxel or an androgen receptor inhibitor (ARi), or with a combination of an ARi, ADT and docetaxel. Darolutamide (NUBEQA®) is an orally administered ARi which has been approved in combination with ADT and docetaxel for the treatment of mHSPC. In a clinical trial, darolutamide plus ADT and docetaxel was effective in prolonging the survival of patients in comparison with placebo plus ADT and docetaxel. Darolutamide plus ADT and docetaxel had a manageable tolerability profile and the adverse events reported with darolutamide plus ADT and docetaxel were consistent with those reported for ADT and docetaxel. Overall, darolutamide expands the availability of treatments for mHSPC and may be useful for patients with more severe disease.

RESUMO

Fezolinetant (VEOZAH™) is an oral, small molecule, neurokinin 3 receptor (NK3R) antagonist, which is being developed by Astellas Pharma Inc. for the treatment of moderate to severe vasomotor symptoms (VMS) or hot flashes due to menopause. Inhibiting NK3R-mediated signalling in the central nervous system is a non-hormonal strategy to modulate the activity of neurones that are associated with thermoregulation, thereby reducing the frequency and severity of VMS. Fezolinetant received its first approval in the USA in May 2023 for the treatment of moderate to severe VMS due to menopause. This article summarizes the milestones in the development of fezolinetant leading to this first approval in this indication.

RESUMO

MYL-1402O (Abevmy®, Lextemy®) is a biosimilar of the reference anti-vascular endothelial growth factor antibody bevacizumab. Abevmy® is approved for use in all indications for which reference bevacizumab is approved, including the treatment of non-small cell lung cancer (NSCLC) and other solid cancers. Lextemy® is approved for all indications as reference bevacizumab, except in recurrent ovarian cancer. MYL-1402O has similar physicochemical and pharmacodynamic properties to those of reference bevacizumab, and the pharmacokinetic similarity of the agents has been shown in healthy male subjects. MYL-1402O demonstrated clinical efficacy equivalent to that of reference bevacizumab in patients with non-squamous NSCLC. The tolerability, safety and immunogenicity profiles of MYL-1402O were consistent with those of reference bevacizumab. The role of reference bevacizumab in the management of solid cancers is well established and MYL-1402O provides an effective biosimilar alternative for patients requiring bevacizumab therapy.

RESUMO

Sotorasib (LUMAKRAS™ in the USA and LUMYKRAS™ in the EU) is an orally active, first-in-class G12C-mutant KRAS (KRASG12C) inhibitor. By binding irreversibly to KRASG12C, sotorasib inhibits downstream signalling pathways which are associated with cell growth and differentiation. Sotorasib is indicated for the treatment of adults with advanced, previously treated, KRAS G12C mutation-positive non-small cell lung cancer (NSCLC) in multiple countries, including the countries of the EU and the USA. A clinically relevant objective response rate was observed in patients with KRAS G12C mutation-positive NSCLC during the primary analysis and in an updated analysis of the phase I/II CodeBreaK 100 trial. Furthermore, a clinically relevant response duration was reported in updated analyses of the trial. Sotorasib has a manageable tolerability profile, with permitted dose modifications to manage toxicity. In summary, sotorasib is a promising KRASG12C inhibitor that increases the available treatment options for patients with KRAS G12C mutation-positive NSCLC who were previously treated with platinum-based chemotherapy and/or immunotherapy.


KRAS is a protein that is involved in cell signalling pathways, including those that are associated with cell growth and differentiation. KRAS mutations are detected in 23% of patients with non-small cell lung cancer (NSCLC), with the G12C mutation being the most common. G12C-mutant KRAS (KRASG12C) is kept in an activated state, which is associated with cancer. Sotorasib (LUMAKRAS™ in the USA and LUMYKRAS™ in the EU), which is taken orally once daily, is the first approved drug that inhibits KRASG12C; it permanently binds to KRASG12C and locks it in an inactivated state. Sotorasib is approved for adults who have advanced, previously treated, KRAS G12C mutation-positive NSCLC. In a clinical trial in patients with KRAS G12C mutation-positive NSCLC, a clinically relevant proportion of patients responded to sotorasib treatment. Furthermore, the duration of effectiveness with sotorasib was considered to be clinically relevant. Adverse reactions with sotorasib treatment were manageable; the dose may be decreased and/or sotorasib treatment may be temporarily stopped to manage adverse reactions. Overall, sotorasib is a promising treatment option for patients with KRAS G12C mutation-positive NSCLC who have received at least one prior systemic therapy.

RESUMO

Avacopan (TAVNEOS™) is a complement 5a receptor (C5aR) antagonist developed by ChemoCentryx for the treatment of autoimmune diseases including anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis. The therapeutic effects of avacopan are attributed to the inhibition of C5aR activity on neutrophils, however, the exact mechanism of therapeutic efficacy in patients with ANCA-associated vasculitis has not been established. In September 2021, avacopan received its first approval in Japan for the treatment of microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA), the two most common forms of ANCA-associated vasculitis, where it is being commercialized by Kissei Pharmaceutical through a partnership with Vifor Pharma. In October 2021, avacopan was approved in the USA as an adjunctive treatment in adults for severe active ANCA-associated vasculitis (specifically MPA and GPA) in combination with standard therapy including glucocorticoids (avacopan does not eliminate glucocorticoid use). Avacopan has received a positive opinion in the EU, and is also undergoing regulatory review in Switzerland and Canada. Avacopan is being investigated for the treatment of complement component 3 glomerulopathy, hidradenitis suppurativa, lupus nephritis and IgA nephropathy. This article summarizes the milestones in the development of avacopan leading to these first approvals in Japan and the USA.

RESUMO

Augmentation genioplasty is a common surgical procedure with extremely low infection rates. We present the case of a healthy middle-aged woman who experienced years of chronic infection after chin implantation due to an exposed mandibular canine root, which is exceedingly rare. Awareness of this potential complication may reduce patient morbidity.

RESUMO

Estetrol/drospirenone is a combined oral contraceptive (COC) with a plant-synthesised foetal oestrogen (estetrol) and a well-established progestin (drospirenone). In preclinical models, estetrol has lower binding affinity for the oestrogen receptor-α (ER-α) in contrast to estradiol and has antagonistic properties against membrane ER-α in several tissues, including the breast, while retaining agonistic activity on receptors located in the nucleus. The low oestrogenicity of estetrol may potentially contribute to reduced thrombotic risk. Estetrol/drospirenone was an effective contraceptive in phase II and III clinical trials, with regular and predictable bleeding cycles maintained in the majority of women. Estetrol/drospirenone was generally well-tolerated with metrorrhagia reported as the most common treatment-related adverse event, which is consistent with other COCs. Cases of migraines with aura (or severe migraines), deep vein thrombosis, hyperkalaemia and depression were rarely reported during the phase III trials. Overall, estetrol/drospirenone is an effective and generally well-tolerated COC, with a potentially reduced risk of thrombosis.


In 2019, an estimated 44% of women aged 15­49 years worldwide used modern contraception methods, and in these women using modern methods, 18% used an oral contraceptive. Estetrol/drospirenone is a combined oral contraceptive (COC) which uses estetrol, a plant-synthesised oestrogen naturally produced by the human foetal liver during pregnancy, in combination with drospirenone, a well-known progestin. Combined, these hormones suppress ovulation, which constitutes their primary mode of action in preventing pregnancy. As estetrol has weaker oestrogen-related effects, it may potentially reduce the risk for blood clots. Estetrol/drospirenone was an effective contraceptive in clinical trials, and most women had regular and predictable bleeding cycles. Metrorrhagia (i.e. abnormal bleeding) was the most commonly reported treatment-related adverse effect; however, this is a common issue with hormonal contraceptives. Cases of severe migraine headaches, deep vein thrombosis, high potassium levels or depression were rarely reported during clinical trials. Estetrol/drospirenone is an effective oral contraceptive, which may offer a contraceptive option with a lower risk for blood clots. However, further research is required to confirm the reduced risk of clotting.

RESUMO

Delafloxacin (BAXDELA® in the USA; Quofenix® in the EU) is an anionic fluoroquinolone antibacterial that is approved for the treatment of community-acquired pneumonia (CAP) and acute bacterial skin and skin structure infections in adults. Delafloxacin demonstrated in vitro activity against Gram-positive and Gram-negative pathogens, including drug-resistant isolates. In a phase III trial in adults with CAP, delafloxacin was noninferior to moxifloxacin when assessed against FDA- and EMA-defined primary endpoints, with both fluoroquinolones achieving high treatment success rates. A prespecified subgroup analysis suggested that delafloxacin may be more efficacious than moxifloxacin in patients with a history of asthma or chronic obstructive pulmonary disease (COPD). Delafloxacin was generally well tolerated in patients with CAP, with most treatment-emergent adverse events graded as mild or moderate in severity. Fluoroquinolone-associated adverse events of special interest occurred infrequently, with no events of QT prolongation or phototoxicity reported with delafloxacin. Delafloxacin is an effective and generally well-tolerated treatment that increases the number of available treatments for CAP and, although further research is required, may be a useful option for patients with CAP and comorbid asthma or COPD.


Community-acquired pneumonia (CAP) can be caused by bacterial infection of the lungs, and is a common cause of infection-related deaths. As drug-resistant bacteria are becoming more common, new antibacterial drugs are needed. Delafloxacin (BAXDELA® in the USA; Quofenix® in the EU) is a fluoroquinolone antibacterial that inhibits bacterial enzymes required for DNA repair and replication. Delafloxacin kills a wide range of bacteria, including some drug-resistant variants. During a trial in adults with CAP, delafloxacin was as effective as moxifloxacin (also a fluoroquinolone antibacterial). Delafloxacin may be more effective than moxifloxacin in patients with a history of asthma or chronic obstructive pulmonary disease (COPD), although further research is needed. Most adverse events with delafloxacin were mild or moderate in severity, with diarrhoea being the most commonly occurring treatment-related adverse event (experienced by < 4% of recipients). Furthermore, the adverse effects of delafloxacin were generally consistent with those previously observed in patients with skin infections. Delafloxacin expands the range of treatments for CAP, and is potentially useful for patients with comorbid asthma or COPD.

RESUMO

OBJECTIVE: To report a case of a recurrent intramuscular hemangioma (IMH) of the lower lip of a 68-year-old female and review the published literature to provide an overview of the presentation, diagnostic strategy, pathological classification, and management of these lesions within the oral cavity. METHODS: A case report was conducted by reviewing the documentation at a single institution. A systematic literature review on OVID MEDLINE and PubMed was performed using the MESH terms "intramuscular hemangioma" and "oral cavity," "tongue," "cheek," "buccal," "gingiva," and "lip." RESULTS: A 62-year-old female presented to our institution with a 2 × 2 × 1 cm IMH of the lower lip involving the surrounding orbicularis oris muscle. She underwent a submucosal resection and did well postoperatively. Six and a half years later, she represented to our institution with a new lower lip lesion in the area of her previous resection. Preoperative magnetic resonance imaging showed a new 10 × 11 mm lesion with a well circumscribed central component surrounded by ill-defined tissue. Preoperative angiography showed that the lesion was supplied by vessels branching off the left facial artery, which were embolized. She underwent wide-local excision (WLE) with bilateral advancement flaps and at her 2-month postoperative visit has not had recurrence. CONCLUSION: Only 39 cases of IMH in the oral cavity have been reported, with only 3 others occurring in the lower lip. Here we add the first case of an IMH of the oral cavity that recurred after primary WLE. The patient was successfully retreated with WLE. At a 3-month follow-up visit, she noted some incompetence with oral secretions and occasional tingling along the incision site but no evidence of recurrence.
