Successful medical management of a pituitary macroadenoma with features of resistant acromegaly and hyperprolactinemia using pasireotide.

BACKGROUND: The somatostatin analog, pasireotide, is used for the treatment of acromegaly after the failure of surgery and/or first-line medical treatment. CASE PRESENTATION: A 48-year-old male reported that during a workup for obesity in his home country, hyperprolactinemia was diagnosed and a 3.5 × 3.5 cm pituitary macroadenoma was identified on pituitary MRI. He received cabergoline for 6 months; then he was lost to follow-up. He presented at our Endocrine clinic 2 years later for treatment of obesity (BMI 49.5 kg/m2). Biochemical workup revealed that in addition to hyperprolactinemia (7,237 [normal: 85-323 mIU/L), he had acromegaly, evident by elevated insulin-like growth factor 1 (IGF-1) level (450 [normal: 88-210 µg/L]), and a positive growth hormone suppression test, secondary hypothyroidism, and secondary hypogonadism. Pituitary MRI showed that the adenoma encased parts of the left and right internal carotid arteries and encroached on the optic chiasm. Surgical excision was therefore not feasible. He was treated with cabergoline and later, long-acting release (LAR) octreotide. Prolactin levels were reduced with cabergoline, but IGF-1 levels did not respond to octreotide, and it was discontinued. The patient abandoned radiotherapy after two sessions. He was started on LAR pasireotide 40 mg every 4 weeks and continued on cabergoline 0.5 mg per week. His biochemical response was dramatic, with a near normalization of IGF-1 levels in 3 months. After 6 months from starting pasireotide, we increased cabergoline dose from 0.5 mg/week to 3 mg/week. Three months later, IGF-1 level was normalized. The patient developed type 2 diabetes as a side effect of pasireotide; however, this was well-controlled with medications. CONCLUSIONS: The case suggests that pasireotide can provide marked biochemical improvement in acromegaly after the failure of both cabergoline monotherapy and cabergoline plus octreotide. This further confirms a potentially efficacious treatment regimen in treatment-resistant acromegaly with hyperprolactinemia.

Phytochemical analysis and evaluation of its antioxidant, antimicrobial, and cytotoxic activities for different extracts of Casuarina equisetifolia.

BACKGROUND: Casuarina equisetifolia belongs to the Casuarina species with the most extensive natural distribution, which contain various phytochemicals with potential health benefits. This study aimed to investigate the chemical composition and biological activities of different extracts of Casuarina equisetifolia. METHODS: The n-hexane extract was analyzed for its unsaponifiable and fatty acid methyl esters fractions, while chloroform, ethyl acetate, and butanol extracts were studied for their phenolic components. Six different extracts of C. equisetifolia needles were evaluated for their total phenolic content, total flavonoid content, and their antioxidant, antimicrobial, and cytotoxic activities. RESULTS: The n-hexane extract contained mainly hydrocarbons and fatty acid methyl esters, while ten phenolic compounds were isolated and identified in the chloroform, ethyl acetate, and butanol extracts. The methanolic extract exhibited the highest total phenolic and flavonoid content, highest antioxidant activity, and most potent cytotoxic activity against HepG-2 and HCT-116 cancer cell lines. The ethyl acetate extract showed the most significant inhibition zone against Staphylococcus aureus and Bacillus subtilis. CONCLUSION: Casuarina equisetifolia extracts showed promising antioxidant, antimicrobial, and cytotoxic activities. Overall, Casuarina equisetifolia is a versatile tree with a variety of uses, and its plant material can be used for many different purposes.

Effect of phosphodiesterase type 5 inhibitors on surgical outcome of ventricular septal defect and pulmonary hypertension patients.

BACKGROUND: Children with ventricular septal defect (VSD) and large systemic-to-pulmonary shunts eventually develop pulmonary hypertension (PH). The perioperative management of patients with VSD and PH is quite troublesome and still debatable, especially in developing countries where the different management options and standardization of treatment is not available. Oral phosphodiesterase type 5 (PDE-5) inhibitors are good treatment options being widely available, cheap, easy administration and do not require extensive monitoring. The aim of our study was to evaluate the effect of the PDE-5 inhibitors when given orally, early preoperative and continued for 3 months postoperative on controlling postoperative PH with its effect on right ventricle (RV) functions. Fifty-one patients were randomly assigned to either sildenafil or tadalafil, 1 week before and continued for 3 months after corrective surgery. The control group received a placebo. RESULTS: There was no significant difference in the improvement in the right ventricle systolic pressure (RVSP) between both groups, early in the postoperative period (P = 0.255) and in follow-up (P = 0.259). There was also no significant difference in the changes in mean pulmonary artery pressure (mPAP), postoperatively and on follow-up (P = 0.788 and 0.059, respectively). There was a drop in RV functions in both groups postoperatively which improved on follow-up; however, it was not significant between both groups. The length of intensive care unit (ICU) stay was similar between both groups (P = 0.143). CONCLUSION: Perioperative administration of PDE-5 inhibitors does not have an impact on the clinical course as regards improvement in pulmonary artery (PA) pressure, ventricular functions and ICU stay.

Ameliorative effect of Nyctanthes arbor-tristis L. by suppression of pentylenetetrazole-induced kindling in mice: An insight from EEG, neurobehavioral and in-silico studies.

Epilepsy is an abiding condition associated with recurrent seizure attacks along with associated neurological and psychological emanation owing to disparity of excitatory and inhibitory neurotransmission. The current study encompasses the assessment of the Nyctanthes arbor-tristis L. methanolic extract (Na.Cr) in the management of convulsive state and concomitant conditions owing to epilepsy. The latency of seizure incidence was assessed using pentylenetetrazol (PTZ) kindling models along with EEG in Na.Cr pretreated mice, trailed by behavior assessment (anxiety and memory), biochemical assay, histopathological alterations, chemical profiling through GCMS, and molecular docking. The chronic assessment of PTZ-induced kindled mice depicted salvation in a dose-related pattern and outcomes were noticeable with extract at 400 mg/kg. The extract at 400 mg/kg defends the progress of kindling seizures and associated EEG. Co-morbid conditions in mice emanating owing to epileptic outbreaks were validated by behavioral testing and the outcome depicted a noticeable defense related to anxiety (P<0.001) and cognitive deficit (P<0.001) at 400 mg/kg. The isolated brains were evaluated for oxidative stress and the outcome demonstrated a noticeable effect in a dose-dependent pattern. Treatment with Na.Cr. also preserved the brain from PTZ induced neuronal damage as indicated by histopathological analysis. Furthermore, the GCMS outcome predicted 28 compounds abundantly found in the plant. The results congregated in the current experiments deliver valued evidence about the defensive response apportioned by Na.Cr which might be due to decline in oxidative stress, AChE level, and GABAergic modulation. These activities may contribute to fundamental pharmacology and elucidate some mechanisms behind the activities of Nyctanthes arbor-tristis.

Factors Affecting the Satisfaction of Women Employees in Health Sector: A Perception Study in Saudi Arabia.

Purpose: Broad evidence points out that women workers in Saudi Arabia face a range of inequitable work practices despite continued efforts for gender equality. The study aims to assess the satisfaction of Saudi women working in the health sector among certain factors in the work environment, factors that enable them to gain opportunities and benefits and make decisions. Patients and Methods: This is a cross-sectional study, which involved the use of closed-ended surveys on 261 Saudi women working in the healthcare sector. Results: Most of the females were aged between 25 and 34 years (59%) and more than half of them worked in the governmental sector (53%). Fifty-eight percent of the females hold clinical jobs, 25% of the administrative jobs were 37% of them have more than 19 years of working experience. The finding showed a significant association between female workers in health sector satisfaction with factors related to the workplace environment, training, and development, and their involvement in decision-making. Conclusion: Most women felt empowered when they received equitable tasks and were able to reach managerial-level positions in their organizations. Establishing a positive work environment characterized by opportunities has the potential to enhance women workers' satisfaction.

Tricuspid valve and right-heart chamber remodelling in elderly subjects with secondary tricuspid regurgitation.

BACKGROUND: The prevalence of secondary tricuspid regurgitation (TR) increases with ageing, but the exact mechanisms and the pattern of tricuspid valve (TV) remodelling are yet to be defined. This knowledge is needed to guide patient selection for the evolving therapeutic options. We sought to explore the prevalence and predictors of secondary TR in the elderly, as well as the associated pattern of right-heart chamber and TV remodelling. METHODS: Consecutive older subjects (60-year-old or older) were prospectively enrolled and detailed analysis of right-heart chambers and TV was conducted (ClinicalTrials.gov ID: NCT05784883). TR severity was defined based on a multiparametric approach. RESULTS: Out of 213 patients (age, 67.1 ± 5.9 years, 52.6% female), 48.8% had mild and 15.5% had moderate-severe TR. The frequency of moderate-severe TR increased from 4.5% in those without to 32.9% in those with underlying abnormalities of the left/right heart. There was a significant trend of worsening right-heart chamber and TV remodelling across the three grades of TR severity (none-trace, mild, and moderate-severe; p-value for linear trend < 0.001). ROC curve-defined cut-points of TV remodelling parameters predicting moderate-severe TR were annular dilatation ≥3.75 cm (AUC: 0.74), tenting area ≥1.45 cm2 (AUC: 0.67), and leaflet length ≥2.25 cm (AUC: 0.61) with increasing frequency of moderate-severe TR from 7.2% through 64.7%, in those with none vs. all three criteria (p < 0.001). The most important correlate of the three TV remodelling parameters was right ventricular and atrial (RV and RA) dilatation. CONCLUSION: Rather than ageing per se, the presence of underlying cardiac abnormalities determines the frequency of moderate-severe TR. Progressive remodelling of right-heart chambers and TV geometry starts with the development of mild TR. TA dilatation, increased tenting, and leaflet elongation are three important correlates of the development of TR that parallel progressive RV and RA dilatation.Study Registration: ClinicalTrials.gov ID: NCT05784883.

The role of rotational thromboelastometry during the COVID-19 pandemic: a narrative review / 대한마취과학회지

The coronavirus disease 2019 (COVID-19) pandemic is currently recognized as a global health crisis. This viral infection is frequently associated with hypercoagulability, with a high incidence of thromboembolic complications that can be fatal. In many situations, the standard coagulation tests (SCT) fail to detect this state of hypercoagulability in patients with COVID-19 since clotting times are either not or only mildly affected. The role of viscoelastic tests such as rotational thromboelastometry (ROTEM®) during this pandemic is explored in this review. COVID-19-associated coagulopathy, as measured using the rotational thromboelastometry parameters, can vary from hypercoagulability due to increased fibrin polymerization and decreased fibrinolysis to bleeding from hypocoagulability. The use of a multimodal diagnostic and monitoring approach, including both rotational thromboelastometry and SCT, such as plasma fibrinogen and D-dimer concentrations, is recommended. Rotational thromboelastometry provides comprehensive information about the full coagulation status of each patient and detects individual variations. Since COVID-19-associated coagulopathy is a very dynamic process, the phenotype can change during the course of infection and in response to anticoagulation therapy. Data from published literature provide evidence that the combination of rotational thromboelastometry and SCT analysis is helpful in detecting hemostasis issues, guiding anticoagulant therapy, and improving outcomes in COVID-19 patients. However, more research is needed to develop evidence-based guidelines and protocols.

Profile of sexuality and symptoms of lower urinary tract in non-institutionalized elderly

ABSTRACT Introduction: Urinary or sexual dysfunction in the elderly are underreported. However, they are highly prevalent. This study aims to identify the prevalence of these conditions. Objective: The aim is to carry out an investigation in non-institutionalized individuals over 60 years of age, to obtain data on its sexual and urinary health in São Paulo, Campinas, Santo André and Londrina. Results: 6.000 questionnaires were distributed, and 3425 were included in the study, for the analysis of the questionnaires separately. In relation to ADAM, 92% of the 1385 evaluated were suspicious of androgen deficiency (ADAM). As for the male sexual function, it was observed 37% of premature ejaculation. As for the female sexual function, 1300 (74%) did not practice sexual intercourse and the main reasons were: lack of partner and lack of sexual desire. In addition, 988 (78%) of women who had no sexual intercourse responded that they didn't want sex and, more importantly, about 22% of them would like to have sexual intercourse. International prostate symptom score (IPSS) showed gradual worsening of urinary symptoms with increasing age, being the most prevalent: nocturia and urinary urgency. As for the female IPSS, we noted that even after 80 years, the majority have mild symptoms related to voiding dysfunction; with increasing age there is a gradual increase in the result of the IPSS. Conclusion: Due to the large number of sexual and urinary disorders found, we recommend the improvement in health conditions, promoting a better quality of life in the elderly.

Aim: the aim of the study was to assess the prevalence of impacted teeth and its association with sex and age among a sample of the Yemeni population. Materials and Methods: A cross sectional study design was employed. The study included 999 radiographical records of patients who had panoramic X- rays previously done. All radiographs were assessed for the number and type of impacted teeth, pathology-associated impaction, sex, age and location (mandible and/or maxilla). The collected data was analyzed using SPSS®version21 software. Results: The study sample comprised digital panoramic radiographs of Yemeni patients aged 17 to 54 years (mean 26.6 years). The present study found 542 patients (54.3%) presented with at least one impacted tooth. The 17 to 25 years age group of the study sample had the highest prevalence of tooth impaction (28.6%). Only 10 (1.0%) case presented pathologies associated with the impacted teeth. There was a significant difference in the number of male 203 (20.3%) and female 339 (33.9%) patients with impacted teeth (p=0.031). Impacted teeth occurred slightly more often in the mandible (42.8%) compared to the maxilla (42.4%). Conclusion: The prevalence of impacted teeth among a sample of Yemeni population was high. Third molars and canines were the most common impacted teeth. The prevalence of impacted teeth in females was higher than in males and it was higher in the mandible than in the maxilla, with the younger patients with a higher prevalence of impaction.

Impact Of Khat (Catha Edulis) Chewing/Use On Heart Rate And Blood Pressure: A Critical Review

@#Khat leaves chewing/use, which imparts amphetamine like effects on the user, is widely practiced in parts of Africa, the Arabian Peninsula, and among the diaspora communities from these regions. Basic clinical and epidemiological studies from different settings have reported associations of acute coronary syndrome, heart failure, and cardiomyopathy, with khat chewing /use. This review aims to analyse the current evidence of the impact that khat, or its active constituent, cathinone, has on the cardiovascular system (CVS), particularly in two parameters, heart rate (HR) and blood pressure (BP). Subsequently, the possible mechanism of actions of how khat impacts these cardiovascular parameters is discussed, and different studies’ findings are summarised appropriately. The analysis of literature suggests that khat could influence HR and BP by most likely causing tachycardia and hypertension and the impacts might be dose-dependent and time-dependent. However, most of the studies involved different species and study designs, and had different limitations. Additionally, the underlying mechanisms of khat effects on these CVS parameters remain unclear. Therefore, more studies are needed to further support the current evidence of the impacts that khat has on the CVS parameters of HR and BP.

Pharmacological evaluation of smooth muscle relaxant and cardiac-modulation potential of Phyla nodiflora in ex-vivo and in-vivo experiments

OBJECTIVE@#To investigate the pharmacological basis of its uses of Phyla nodiflora (P. nodiflora) for the treatment of anomalies predominantly by smooth muscle containing tissues such as gastrointestinal/vascular/broncho spasm and cardiovascular modulation.@*METHODS@#The crude hydroalcoholic extract of P. nodiflora (Pn.Cr) and its fractions were evaluated on isolated rabbit jejunum, rat trachea, aorta and atrium. To access the contractile or relaxant effects of testing materials, the tissues were mounted in isolated organ bath and responses were recorded with transducers coupled with data acquisition system. BALB/c mice were challenged with castor oil for the assessment of in-vivo antidiarrheal activity. Normotensive rats were used for in-vivo hypotensive study.@*RESULTS@#Hydroalcoholic extract of Pn.Cr at variable concentrations inhibited the natural spontaneous rhythm and 80 mmol/L K mediated contractions in isolated segment of jejunum with EC values of 3.18 and 1.91 mg/mL respectively. Verapamil, a Ca channel blocker, demonstrated akin pattern in jejunum and therefore possibly suggesting calcium blocking activity. On isolated rat tracheal tissue, Pn.Cr showed relaxation of high-K and carbachol mediated contractions (EC values: 1.24 and 2.42 mg/mL). Pn.Cr treatment relaxed the rat aortic ring in a cumulative doses with high-K and phenylephrine-induced contractions (EC values 0.25 and 0.92 mg/mL). Activity based fractionation of Pn.Cr showed that dichloromethane fraction was more potent for relaxing the tissues spasm compared to aqueous fraction. In-vivo experiments, significant protection by Pn.Cr (P < 0.05) was observed in castor oil-induced diarrhea (50-500 mg/kg) whereas hypotensive effect in anesthetized rats was seen at the dose range of 1-10 mg/kg of Pn.Cr (P < 0.05).@*CONCLUSION@#This study suggests the blockage of calcium channel in the smooth muscles as a pharmacological application to make usage of P. nodiflora in the management of diarrhea, asthma and hypotensive effect.

Analysis of the effect of renal excretory system cooling during thermal radiofrequency ablation in an animal model

Objective: Analysis of renal excretory system integrity and efficacy of radiofrequency ablation with and without irrigation with saline at 2 o C (SF2). Materials and Methods: The median third of sixteen kidneys were submitted to radiofrequency (exposition of 1 cm) controlled by intra-surgical ultrasound, with eight minutes cycles and median temperature of 90 o C in eight female pigs. One excretory renal system was cooled with SF2, at a 30ml/min rate, and the other kidney was not. After 14 days of post-operatory, the biggest diameters of the lesions and the radiological aspects of the excretory system were compared by bilateral ascending pyelogram and the animals were sacrificed in order to perform histological analysis. Results: There were no significant differences between the diameters of the kidney lesions whether or not exposed to cooling of the excretory system. Median diameter of the cooled kidneys and not cooled kidneys were respectively (in mm): anteroposterior: 11.46 vs. 12.5 (p = 0.23); longitudinal: 17.94 vs. 18.84 (p = 0.62); depth: 11.38 vs. 12.25 (p = 0.47). There was no lesion of the excretory system or signs of leakage of contrast media or hydronephrosis at ascending pyelogram. Conclusion: Cooling of excretory system during radiofrequency ablation does not significantly alter generated coagulation necrosis or affect the integrity of the excretory system in the studied model. .

Disfunção erétil / Erectile dysfunction

Uma grande revolução no tratamento da disfunção erétil, especialmente após o desenvolvimento dos primeiros inibidores da 5-fosfodiesterase (5-PDE), no final dos anos 90, marcou profundamente a história da sexualidade humana, repercutindo sobretudo na população de difícil tratamento (diabetes mellitus, prostatectomizados por câncer e outros casos de disfunção orgânica). Respeitando a estratégia de tratamento de cada urologista, os pacientes devem ser estimulados a experimentar todos os tipos de inibidores da 5-PDE disponíveis. Na falha da farmacoterapia oral, ou quando houver contraindicação para ela, dever-se-á considerar a injeção intracavernosa e, finalmente, implante cirúrgico de prótese peniana.
