RESUMEN

BACKGROUND The endocrine metabolic disorder polycystic ovary syndrome (PCOS) is quite common among women. Women with PCOS show a compromised health-related quality of life (HRQoL), impaired emotional well-being, and alexithymia, a neuropsychological phenomenon conceptualized as difficulty in recognizing and expressing one's emotions. However, the relationship between alexithymia and HRQoL in women with PCOS is unclear. This study aimed to investigate the impact of alexithymia on HRQoL in women with PCOS in Saudi Arabia. MATERIAL AND METHODS This descriptive cross-sectional, community-based study enrolled 518 female patients with a diagnosis of PCOS from all age groups. The patients were surveyed via a self-administered questionnaire from December 2022 to January 2023. The survey encompassed sociodemographic data, the 20-item Toronto Alexithymia Scale (TAS-20), and HRQoL 15-dimensional scale (15D). RESULTS This study included 320 participants (61.8%) with alexithymia. A significant association was found between alexithymia and low HRQoL 15D scores in patients with PCOS. Specifically, scores on the TAS-20 subscales related to difficulty in identifying feelings and describing feelings were positively correlated with HRQoL (P=0.000). However, externally oriented thinking subscale scores were not positively correlated with HRQoL (P=0.44). CONCLUSIONS The presence of alexithymia is associated with poor HRQoL in women with PCOS, which is more pronounced among those who received a diagnosis ≥4 years ago. Alexithymia must be considered when assessing the HRQoL of patients with PCOS, considering the relatively high prevalence of alexithymia in these patients.

RESUMEN

Gonadoblastoma is an uncommon ovarian tumor arising primarily in females with gonadal dysgenesis and a 46, XY karyotype. Germ cell tumors arising within and/or overgrowing a gonadoblastoma have been reported. We report a rare case of a malignant mixed germ cell tumor (yolk sac tumor and choriocarcinoma) arising in a gonadoblastoma of the left ovary in a 19-year-old female with a 46, XX karyotype. The patient's initial α-fetoprotein level was 20 000 KIU/L. The patient underwent a laparoscopic unilateral salpingo-oophorectomy with omentectomy and peritoneal washing followed by adjuvant chemotherapy.

RESUMEN

INTRODUCTION: High-intensity focused ultrasound (HIFU) is an ablative treatment undergoing assessment for the treatment of benign and malignant disease. We describe the first reported intracavitary HIFU ablation for recurrent, unresectable and symptomatic cervical cancer. CASE DESCRIPTION: A 38 year old woman receiving palliative chemotherapy for metastatic cervical adenocarcinoma was offered ablative treatment from an intracavitary trans-rectal HIFU device (Sonablate® 500). Pre-treatment symptoms included vaginal bleeding and discharge that were sufficient to impede her quality of life. No peri-procedural adverse events occurred. Symptoms resolved completely immediately post-procedure, reappeared at 7 days, increasing to pre-procedural levels by day 30. DISCUSSION AND EVALUATION: This first time experience of intracavitary cervical HIFU suggests that it is feasible for palliation of advanced cervical cancer, with no early evidence of unexpected toxicity. Ethical approval had also been granted for the use of per-vaginal access if appropriate. This route, alone or in combination with the rectal route, may provide increased accessibility in future patients with a redesigned device more suited to trans-vaginal ablations. CONCLUSION: Intracavitary HIFU is a potentially safe procedure for the treatment of cervical cancer and able to provide symptomatic improvement in the palliative setting.

RESUMEN

Local ablative therapies have become an important part in the portfolio of treatment for patients with malignant tumors especially in the liver. Although percutaneous ethanol injection still plays a role, current guidelines favor radiofrequency ablation with a higher efficacy for complete tumor destruction. Nevertheless transplantation and surgical resection remain the gold standard due to their superiority in local control and improved survival. In this manuscript we discuss the technique in detail.

RESUMEN

Deep vein thrombosis is common with an incidence of 1 in 1000. Acute thrombus removal for extensive proximal deep vein thrombosis using catheter-directed techniques highlights the need for accurate assessment of thrombus age. This systematic review summarises experimental and clinical evidence of imaging techniques for aging deep vein thrombosis. Ultrasound elastography and magnetic resonance imaging were highlighted as the most studied imaging modalities. Elastography was shown to distinguish between acute and chronic clots, despite demonstrating difficulty in accurate aging of clots older than 10 days in rat models. Elastography is noted as a feasible adjunct to current first-line imaging for deep vein thrombosis using duplex ultrasonography. Combinations of magnetic resonance imaging techniques can identify acute, sub-acute and chronic thrombi using endogenous contrast agents and provide objective standardisation of the diagnostic process, with reduced onus upon operator dependency. Further validation is required of these novel imaging techniques prior to clinical implementation for deep vein thrombosis aging.

RESUMEN

AIM: In rectal cancer, not all tumours display a response to neoadjuvant treatment. An accurate predictor of response does not exist to guide patient-specific treatment. DNA methylation is a distinctive molecular pathway in colorectal carcinogenesis. Whether DNA methylation is altered by neoadjuvant treatment and a potential response predictor is unknown. We aimed to determine whether DNA methylation is altered by neoadjuvant chemoradiotherapy (CRT) and to determine its role in predicting response to treatment. PATIENTS AND METHODS: Fifty-three (n = 53) patients with locally advanced rectal cancers treated with neoadjuvant CRT followed by surgery were identified from the pathology databases of 2 tertiary referral centres over a 4-year period. Immunohistochemical staining of treatment specimens was carried out using the 5-Methylcytidine (Eurogentec, Seraing, Belgium) antibody. Quantitative analysis of staining was performed using an automated image analysis platform. The modified tumour regression grading system was used to assess tumour response to neoadjuvant therapy. RESULTS: Seven (13%) patients showed complete pathological response while 46 (87%) patients were partial responders to neoadjuvant treatment. In 38 (72%) patients, significant reduction in methylation was observed in post-treatment resection specimens compared to pre-treatment specimens (171.5 vs 152.7, p = 0.01); in 15 (28%) patients, methylation was increased. Pre-treatment methylation correlated significantly with tumour regression (p < 0.001), T-stage (p = 0.005), and was able to predict complete and partial pathological responders (p = 0.01). CONCLUSION: Neoadjuvant CRT appears to alter the rectal cancer epigenome. The significant correlation between pre-treatment DNA methylation with tumour response suggests a potential role for methylation as a biomarker of response.

RESUMEN

BACKGROUND: Benefit from carotid endarterectomy (CEA) in symptomatic moderate (50-69 per cent) carotid stenosis remains marginal. The Fourth National Clinical Guideline for Stroke recommends use of the risk score from the European Carotid Surgery Trial (ECST) to aid decision-making in symptomatic carotid disease. It is not known whether clinicians are, in fact, influenced by it. METHODS: Using the ECST risk prediction model, three scenarios of patients with a low (less than 10 per cent), moderate (20-25 per cent) and high (40-45 per cent) 5-year risk of stroke were devised and validated. Invitations to complete an online survey were sent by e-mail to vascular surgeons and stroke physicians, with responses gathered. The questionnaire was then repeated with the addition of the ECST risk score. RESULTS: Two hundred and one completed surveys were analysed (21·5 per cent response rate): 107 by stroke physicians and 94 by vascular surgeons. The high-risk scenario after the introduction of the ECST risk score showed an increased use of CEA (66·7 versus 80·1 per cent; P = 0·009). The low-risk scenario after risk score analysis demonstrated a swing towards best medical therapy (23·4 versus 57·2 per cent; P < 0·001). CEA was preferred in the moderate-risk scenario and this was not altered significantly by introduction of the risk score (71·6 versus 75·6 per cent; P = 0·609). Vascular surgeons exhibited a preference towards CEA compared with stroke physicians in both low- and moderate-risk scenarios (P < 0·001 and P = 0·003 respectively). CONCLUSION: The addition of a risk score appeared to influence clinicians in their decision-making towards CEA in high-risk patients and towards best medical therapy in low-risk patients.

RESUMEN

Access to homoleptic phosphinine-based coordination compounds of d(6) metals has so far remained elusive. We report here on the preparation and full characterization of the first homoleptic phosphinine-iridium(III) complex, obtained by C-H activation of 2,4,6-triphenylphosphinine with [Ir(acac)3]. This result opens up new perspectives for the implementation of such aromatic heterocycles in more applied research fields.

RESUMEN

A series of 2,4,6-triarylphosphinines were prepared and investigated in the base-assisted cyclometalation reaction using [Cp*IrCl2]2 (Cp* = 1,2,3,4,5-pentamethylcyclopentadienyl) as the metal precursor. Insight in the mechanism of the C-H bond activation of phosphinines as well as in the regioselectivity of the reaction was obtained by time-dependent (31)P{(1)H} NMR spectroscopy. At room temperature, 2,4,6-triarylphosphinines instantaneously open the Ir-dimer and coordinate in an η(1)-fashion to the metal center. Upon heating, a dissociation step towards free ligand and an Ir-acetate species is observed and proven to be a first-order reaction with an activation energy of ΔEA = 56.6 kJ mol(-1) found for 2,4,6-triphenylphosphinine. Electron-donating substituents on the ortho-phenyl groups of the phosphorus heterocycle facilitate the subsequent cyclometalation reaction, indicating an electrophilic C-H activation mechanism. The cyclometalation reaction turned out to be very sensitive to steric effects as even small substituents can have a large effect on the regioselectivity of the reaction. The cyclometalated products were characterized by means of NMR spectroscopy and in several cases by single-crystal X-ray diffraction. Based on the observed trends during the mechanistic investigation, a concerted base-assisted metalation-deprotonation (CMD) mechanism, which is electrophilic in nature, is proposed.

RESUMEN

High-intensity focused ultrasound (HIFU) is a rapidly maturing technology with diverse clinical applications. In the field of oncology, the use of HIFU to non-invasively cause tissue necrosis in a defined target, a technique known as focused ultrasound surgery (FUS), has considerable potential for tumour ablation. In this article, we outline the development and underlying principles of HIFU, overview the limitations and commercially available equipment for FUS, then summarise some of the recent technological advances and experimental clinical trials that we predict will have a positive impact on extending the role of FUS in cancer therapy.

RESUMEN

The bidentate P,N hybrid ligand 1 allows access for the first time to novel cationic phosphinine-based Rh(III) and Ir(III) complexes, broadening significantly the scope of low-coordinate aromatic phosphorus heterocycles for potential applications. The coordination chemistry of 1 towards Rh(III) and Ir(III) was investigated and compared with the analogous 2,2'-bipyridine derivative, 2-(2'-pyridyl)-4,6-diphenylpyridine (2), which showed significant differences. The molecular structures of [RhCl(Cp*)(1)]Cl and [IrCl(Cp*)(1)]Cl (Cp*=pentamethylcyclopentadienyl) were determined by means of X-ray diffraction and confirm the mononuclear nature of the λ(3) -phosphinine-Rh(III) and Ir(III) complexes. In contrast, a different reactivity and coordination behavior was found for the nitrogen analogue 2, especially towards Rh(III) as a bimetallic ion pair [RhCl(Cp*)(2)](+) [RhCl3 (Cp*)](-) is formed rather than a mononuclear coordination compound. [RhCl(Cp*)(1)]Cl and [IrCl(Cp*)(1)]Cl react with water regio- and diastereoselectively at the external PC double bond, leading exclusively to the anti-addition products [MCl(Cp*)(1H⋅OH)]Cl as confirmed by X-ray crystal-structure determination.

RESUMEN

Initially, a set of guidelines for the use of ultrasound contrast agents was published in 2004 dealing only with liver applications. A second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some non-liver applications. Time has moved on, and the need for international guidelines on the use of CEUS in the liver has become apparent. The present document describes the third iteration of recommendations for the hepatic use of contrast enhanced ultrasound (CEUS) using contrast specific imaging techniques. This joint WFUMB-EFSUMB initiative has implicated experts from major leading ultrasound societies worldwide. These liver CEUS guidelines are simultaneously published in the official journals of both organizing federations (i.e., Ultrasound in Medicine and Biology for WFUMB and Ultraschall in der Medizin/European Journal of Ultrasound for EFSUMB). These guidelines and recommendations provide general advice on the use of all currently clinically available ultrasound contrast agents (UCA). They are intended to create standard protocols for the use and administration of UCA in liver applications on an international basis and improve the management of patients worldwide.

RESUMEN

Inguinal herniae are a common pathology found in both paediatric and adult populations. The presence of bowel in the hernia sac is anticipated; however, occasionally other structures may be found within the sac. We describe a case of a leiomyoma that had undergone red degeneration in the inguinal canal of a 26-week pregnant female. With this case report, we hope to expand the diagnostic paradigm in the setting of a painful swelling in the inguinal canal of a pregnant female.
