Introduction: Congenital Tracheal Stenosis (CTS) with complete cartilaginous rings is a rare but potentially life-threatening condition in paediatric patients. Currently, the most common approach is slide tracheoplasty (ST) with sternotomy under cardiopulmonary bypass (CPB). Intending to make the procedure less invasive and consider the variety of associated conditions, we have tailored the approach to our patients, who were treated by a multidisciplinary airway team.

Our knowledge of galaxy formation and evolution has incredibly progressed through multi-wavelength observational constraints of the interstellar medium (ISM) of galaxies at all cosmic epochs. However, little is known about the physical properties of the more diffuse and lower surface brightness reservoir of gas and dust that extends beyond ISM scales and fills dark matter haloes of galaxies up to their virial radii, the circumgalactic medium (CGM). New theoretical studies increasingly stress the relevance of the latter for understanding the feedback and feeding mechanisms that shape galaxies across cosmic times, whose cumulative effects leave clear imprints into the CGM.

Identifying master epigenetic factors controlling proliferation and survival of cancer cells allows to discover new molecular targets exploitable to overcome resistance to current pharmacological regimens. In breast cancer (BC), resistance to endocrine therapy (ET) arises from aberrant Estrogen Receptor alpha (ERα) signaling caused by genetic and epigenetic events still mainly unknown. Targeting key upstream components of the ERα pathway provides a way to interfere with estrogen signaling in cancer cells independently from any other downstream event.

Small non-coding RNAs (sncRNAs) make up ~1% of the transcriptome; nevertheless, they play significant roles in regulating cellular processes. Given the complexity of the central nervous system, sncRNAs likely hold particular importance in the human brain. In this study, we provide sncRNA transcriptomic profiles in a range of adult and prenatal brain regions, with a focus on piRNAs, due to their underexplored expression in somatic cells and tissue-specific nature.

Background:  Rapid spread of the SARS-CoV-2 pandemic in 2020 led to an indirect effect on non-COVID patients. Since neuro-oncology cases are unique and brain tumors need a specific therapeutic protocol at proper doses and at the right times, the effects of the pandemic on health care services for patients with glioblastomas (GBs) and their impact on overall survival (OS) and quality of life are not yet known.

Methods:  We conducted a retrospective study of 142 GB patients who underwent surgery, radiation, and chemotherapy before and after the lockdown period, aiming to determine the differences in access to care, treatment modality, and adjuvant therapies, and how the lockdown changed the prognosis.

Article Synopsis
  • Laser Interstitial Thermotherapy (LITT) is a minimally invasive neurosurgical option for treating intracranial tumors, particularly recurrent gliomas, utilizing heat to target and ablate tumors while monitoring progress through MRI.
  • The technique is gaining traction due to shorter recovery times, its applicability for patients with multiple health issues, and the ability to provide tumor control—usable alone or alongside other treatments like chemotherapy and radiation.
  • Recent studies show a mix of outcomes regarding the efficacy and safety of LITT, emphasizing the importance of tumor characteristics, patient selection, and surgical expertise, while future research should focus on prospective studies to better outline LITT's role in treating recurrent gliomas.

Article Synopsis
  • The study evaluated the impact of opening the lateral ventricle during surgery on post-surgical complications in patients with high-grade gliomas (HGG), comparing outcomes of those who had the ventricle opened versus those who did not.
  • A total of 380 patients were studied, with a median overall survival (OS) of 16.6 months and progression-free survival (PFS) of 10.9 months, revealing some complications but not directly linked to the ventricle opening.
  • The findings suggest that opening the lateral ventricles does not significantly increase the risk of complications such as dissemination or hydrocephalus, and it may be necessary for achieving better surgical removal of the tumor.

Clear cell renal cell carcinoma (ccRCC) is the most common kidney cancer in the adult population. Late diagnosis, resistance to therapeutics and recurrence of metastatic lesions account for the highest mortality rate among kidney cancer patients. Identifying novel biomarkers for early cancer detection and elucidating the mechanisms underlying ccRCC will provide clues to treat this aggressive malignant tumor.

Epithelial ovarian cancers (EOC) associated with germline or somatic BRCA pathogenetic variants have a significantly higher rate of TP53aberrations. The majority of TP53 mutations are detectable by immunohistochemistry and several studies demonstrated that an abnormal p53 pattern characterized high-grade EOCs. An abnormal p53 immunohistochemical staining in fallopian tube (serous tubal intraepithelial carcinoma (STIC) and "p53 signature" is considered as a precancerous lesion of high-grade EOCs and it is often found in fallopian tube tissues of BRCA germline mutated patients suggesting that STIC is an early lesion and the TP53 mutation is an early driver event of BRCA mutated high-grade EOCs.

The transcription factor FOXP2, a regulator of vocalization- and speech/language-related phenotypes, contains two long polyQ repeats (Q and Q) displaying marked, still enigmatic length variation across mammals. We found that the Q/Q length ratio quantitatively encodes vocalization frequency ranges, from the infrasonic to the ultrasonic, displaying striking convergent evolution patterns. Thus, species emitting ultrasonic vocalizations converge with bats in having a low ratio, whereas species vocalizing in the low-frequency/infrasonic range converge with elephants and whales, which have higher ratios.
