Usefulness and Potential Pitfalls of Long-Acting Growth Hormone Analogs.

Daily recombinant human GH (rhGH) is currently approved for use in children and adults with GH deficiency (GHD) in many countries with relatively few side-effects. Nevertheless, daily injections can be painful and distressing for some patients, often resulting in non-adherence and reduction of treatment outcomes. This has prompted the development of numerous long-acting GH (LAGH) analogs that allow for decreased injection frequency, ranging from weekly, bi-weekly to monthly.

Experience of a Pituitary Clinic for US Military Veterans With Traumatic Brain Injury.

Context: Traumatic brain injury (TBI) is considered the "signature" injury of veterans returning from wartime conflicts in Iraq and Afghanistan. While moderate/severe TBI is associated with pituitary dysfunction, this association has not been well established in the military setting and in mild TBI (mTBI). Screening for pituitary dysfunction resulting from TBI in veteran populations is inconsistent across Veterans Affairs (VA) institutions, and such dysfunction often goes unrecognized and untreated.

Effects of oral macimorelin on copeptin and anterior pituitary hormones in healthy volunteers.

Purpose: The test with the highest diagnostic accuracy for diabetes insipidus is copeptin measurement after hypertonic saline infusion. However, the procedure is cumbersome and unpleasant due to rapid sodium increase. An oral stimulation test would be highly desirable.

Adult growth hormone deficiency guidelines: more difficult than it seems to incorporate into clinical practice universally.

Adult growth hormone deficiency (GHD) is a syndrome characterized by adverse phenotypic, metabolic, and quality-of-life features. Over the past 2 decades, there is accumulating evidence demonstrating improvement of most of these parameters when GH is optimally replaced. Appropriate selection of patients at risk of GHD is crucial when considering and performing testing to establish the diagnosis.

Important Management Considerations In Patients With Pituitary Disorders During The Time Of The Covid-19 Pandemic.

Objective: In December 2019, a novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused an outbreak of coronavirus disease 2019 (COVID-19) that resulted in a global pandemic with substantial morbidity and mortality. Currently, there is no specific treatment or approved vaccine against COVID-19. The underlying associated comorbidity and diminished immune function of some pituitary patients (whether caused by the disease and its sequelae or treatment with excess glucocorticoids) increases their risk of contracting and developing complications from COVID-19 infection.

Adult growth hormone deficiency: Optimizing transition of care from pediatric to adult services.

Objective: Most patients with childhood-onset growth hormone deficiency (CO-GHD) receive treatment with exogenous growth hormone (GH) to facilitate the attainment of their full potential adult height. Recent evidence suggests that continuing GH administration during the transition period between the end of linear growth and full adult maturity is necessary for proper body composition and bone and muscle health, and may also have beneficial effects on metabolic parameters, bone mineral density, and quality of life. The timing of this transition period coincides with the transfer of care from a pediatric to an adult endocrinologist, creating the potential for a care gap as a consequence of losing the patient to follow-up.

Sensitivity and specificity of the macimorelin test for diagnosis of AGHD.

Objective: The macimorelin test is approved for the diagnosis of adult growth hormone deficiency (AGHD) based on its efficacy vs the insulin tolerance test (ITT). Macimorelin has a significant advantage over ITT in avoiding hypoglycemia. Analyses were conducted to determine whether macimorelin performance is affected by age, BMI, or sex, and evaluate its performance vs ITT over a range of GH cutpoints.

Clinical management of patients with Cushing syndrome treated with mifepristone: consensus recommendations.

Background: While surgery is the first-line treatment for patients with endogenous hypercortisolism (Cushing syndrome [CS]), mifepristone has been shown to be a beneficial medical treatment option, as demonstrated in the SEISMIC (Study of the Efficacy and Safety of Mifepristone in the Treatment of Endogenous Cushing Syndrome) trial. Mifepristone is a competitive glucocorticoid receptor antagonist and progesterone receptor antagonist that is associated with several treatment effects and adverse events that clinicians need to be aware of when considering its use. The objective of this review was to provide updated clinical management recommendations for patients with CS treated with mifepristone.

EGFR/ErbB2-Targeting Lapatinib Therapy for Aggressive Prolactinomas.

Context: Approximately 10% to 20% of prolactinomas are resistant to dopamine agonist therapy. The ErbB signaling pathway may drive aggressive prolactinoma behavior.

Objective: We evaluated lapatinib, an ErbB1-epidermal growth factor receptor (EGFR)/ErbB2 or human EGFR2 (HER2) tyrosine kinase inhibitor (TKI), in aggressive prolactinomas.

Maladaptive Denial of Severe Pain and Acute Orthopedic Injuries in a Patient With a Schizoaffective Disorder.

Persistent denial of severe and acute pain following orthopedic injuries has not been previously reported. We present a case of a 24-year-old woman with a history of schizoaffective disorder who suffered severe pain secondary to acute orthopedic injuries who insisted, "I am fine! There is nothing wrong with me." Her maladaptive denial resulted in an initial refusal of necessary medical/surgical care, but she eventually accepted the necessary treatments despite her persistent belief she did not need such care.

Gallic acid potentiates the apoptotic effect of paclitaxel and carboplatin via overexpression of Bax and P53 on the MCF-7 human breast cancer cell line.

Despite advances in treatment, breast cancer remains the widest spread disease among females with a high mortality rate. We investigated the potential effects of gallic acid (GA) as supportive therapy in the management of breast cancer. Anti-cancer activity with GA alone or in combination with paclitaxel and/or carboplatin was assessed by MTT assay and flow cytometry using annexin V/propidium iodide.

Multidisciplinary management of acromegaly: A consensus.

The 13th Acromegaly Consensus Conference was held in November 2019 in Fort Lauderdale, Florida, and comprised acromegaly experts including endocrinologists and neurosurgeons who considered optimal approaches for multidisciplinary acromegaly management. Focused discussions reviewed techniques, results, and side effects of surgery, radiotherapy, and medical therapy, and how advances in technology and novel techniques have changed the way these modalities are used alone or in combination. Effects of treatment on patient outcomes were considered, along with strategies for optimizing and personalizing therapeutic approaches.

Cost-Effectiveness and Efficacy of a Novel Combination Regimen in Acromegaly: A Prospective, Randomized Trial.

Context: Combination therapy with somatostatin receptor ligand (SRL) plus pegvisomant for patients with acromegaly is recommended after a maximizing dose on monotherapy. Lower-dose combination regimens are not well studied.

Objective: To compare cost-effectiveness and efficacy of 3 lower-dose combination regimens in controlled and uncontrolled acromegaly.

Alterations of the GH/IGF-I Axis and Gut Microbiome after Traumatic Brain Injury: A New Clinical Syndrome?

Context: Pituitary dysfunction with abnormal growth hormone (GH) secretion and neurocognitive deficits are common consequences of traumatic brain injury (TBI). Recognizing the comorbidity of these symptoms is of clinical importance; however, efficacious treatment is currently lacking.

Evidence Acquisition: A review of studies in PubMed published between January 1980 to March 2020 and ongoing clinical trials was conducted using the search terms "growth hormone," "traumatic brain injury," and "gut microbiome.

A Review on Non-invasive Respiratory Support for Management of Respiratory Distress in Extremely Preterm Infants.

Majority of extremely preterm infants require positive pressure ventilatory support at the time of delivery or during the transitional period. Most of these infants present with respiratory distress (RD) and continue to require significant respiratory support in the neonatal intensive care unit (NICU). Bronchopulmonary dysplasia (BPD) remains as one of the major morbidities among survivors of the extremely preterm infants.

Gardner-Diamond Syndrome: A Psychodermatological Condition in the Setting of Immunodeficiency.

Gardner-Diamond syndrome (GDS) is a psychological and dermatologic syndrome involving painful, ecchymotic, purpuric lesions that typically appear after a period of stress or minor trauma. This syndrome most commonly occurs in young women, though it has also been less commonly reported in men and adolescents. It is an uncommon condition and appropriate diagnosis is important to properly manage symptoms and minimize risks to patients.

Human Tat-specific factor 1 binds the HIV-1 genome and selectively transports HIV-1 RNAs.

Human immunodeficiency virus type 1 (HIV-1) propagation requires many human cofactors. Multiple groups have demonstrated that Tat-specific factor 1 (Tat-SF1) is an HIV-1 dependency factor. Depletion of this protein lowers HIV-1 infectivity, however, it does not affect the overall levels of viral RNA.

Adult growth hormone deficiency: clinical advances and approaches to improve adherence.

: There have been significant clinical advances in the understanding of the diagnosis and benefits of long-term recombinant human growth hormone (rhGH) replacement in adults with GH deficiency (GHD) since its approval in 1996 by the United States Food and Drug Administration.: We searched PubMed, Medline, CINAHL, EMBASE and PsychInfo databases between January 2000 and June 2019 for published studies evaluating adults with GHD. We reviewed the data of the oral macimorelin test compared to the GHRH plus arginine and the insulin tolerance tests that led to its approval by the United States FDA and European Medicines Agency for adult diagnostic testing.

A Standard Numbering Scheme for Class C β-Lactamases.

Unlike for classes A and B, a standardized amino acid numbering scheme has not been proposed for the class C (AmpC) β-lactamases, which complicates communication in the field. Here, we propose a scheme developed through a collaborative approach that considers both sequence and structure, preserves traditional numbering of catalytically important residues (Ser, Lys, Tyr, and Lys), is adaptable to new variants or enzymes yet to be discovered and includes a variation for genetic and epidemiological applications.

Mifepristone Increases Thyroid Hormone Requirements in Patients With Central Hypothyroidism: A Multicenter Study.

Purpose: Mifepristone is a glucocorticoid and progesterone receptor blocker that can be used for patients with hyperglycemia and Cushing syndrome in whom surgery failed to achieve remission or who were ineligible for surgery. We report a case series of patients with Cushing disease (CD) and central hypothyroidism that presented with increased levothyroxine requirements during mifepristone therapy.

Methods: Retrospective longitudinal case series of patients with CD and central hypothyroidism treated with mifepristone in a retrospective database at four pituitary centers in the United States.

Sodium Perturbations After Pituitary Surgery.

Sodium perturbations are a common complication after pituitary surgery, with hyponatremia being the most frequent. Postoperative assessments should be tailored to the early and late periods, and monitoring sodium perturbations is recommended. Cerebral salt wasting is rare after pituitary surgery, and diagnosis and management can be challenging.
