Preserving water and soil resources ranks among the top priorities outlined in the national water strategy. Indeed, the integrated management of water resources in vulnerable territories, particularly in Morocco, requires a deep knowledge of the hydrological functioning and use of water resources in these regions. The diverse hydroclimatic and morphological features within the Ouljet Es Soltane watershed, which is a sub-basin of the extensive Oued Sebou watershed, present significant challenges in managing its water and soil resources.

Cerebrospinal fluid (CSF) protein levels exhibit high variability in HIV-associated cryptococcal meningitis; however, its clinical implications remain unclear. We analyzed data from 890 adults with HIV-associated cryptococcal meningitis randomized into two clinical trials in Uganda between 2015 and 2021. CSF protein was grouped into < 100 mg/dl (72%, n = 641) and ≥ 100 mg/dl (28%, n = 249).

Article Synopsis
  • Mortality rates for adults with HIV-associated cryptococcal meningitis are high, between 24% and 40%, and the study explores mid-upper arm circumference (MUAC) as a modifiable risk factor for mortality.
  • In a study of 433 Ugandan adults, those with a MUAC of 22 cm or less had significantly higher mortality rates, with 62% dying by the 18-week mark, indicating a strong correlation between nutritional state and survival.
  • The findings suggest that MUAC can serve as an easy, bedside indicator to identify high-risk patients and pave the way for potential nutritional interventions to improve outcomes.

Objectives: Endovascular thrombectomy (EVT) dramatically improves clinical outcomes, but the reduction in final infarct volume only accounts for 10-15 % of the treatment benefit. We aimed to develop a novel MRI-ADC-based metric that quantify the degree of tissue injury to test the hypothesis that it outperforms infarct volume in predicting long-term outcome.

Materials And Methods: A single-center cohort consisted of consecutive acute stroke patients with anterior circulation large vessel occlusion, successful recanalization via EVT (mTICI ≥2b), and MRI of the brain between 12 h and 7 days post-EVT.

Background: Sentinel lymph node biopsy (SLNB) with injection of radiopharmaceuticals is now the standard of care for staging the axilla in patients with breast cancer. Sulfur or antimony colloids labeled with Technetium (Tc) are used globally for the procedure, with a detection rate of 94%. However, in Iran, Tc phytate has been used because it is more easily producible in the country.

Article Synopsis
  • In a study of 890 adults with HIV-associated cryptococcal meningitis, researchers found that cerebrospinal fluid (CSF) protein levels varied significantly, impacting clinical outcomes.
  • Approximately one-third of the participants had elevated CSF protein (≥100 mg/dL), leading to associations with more severe clinical presentations, such as impaired consciousness and seizures, but also indicated better fungal clearance and immune responses.
  • The study concluded that higher CSF protein levels could be a useful indicator for immune activation and could help predict patient prognosis in cryptococcal meningitis.

Cryptococcal meningitis is a leading cause of morbidity and mortality globally, especially in people with advanced HIV disease. Cryptococcal meningitis is responsible for nearly 20% of all deaths related to advanced HIV disease, with the burden of disease predominantly experienced by people in resource-limited countries. Major advancements in diagnostics have introduced low-cost, easy-to-use antigen tests with remarkably high sensitivity and specificity.

Cryptococcus neoformans and Cryptococcus gattii species complexes cause meningoencephalitis with high fatality rates and considerable morbidity, particularly in persons with deficient T cell-mediated immunity, most commonly affecting people living with HIV. Whereas the global incidence of HIV-associated cryptococcal meningitis (HIV-CM) has decreased over the past decade, cryptococcosis still accounts for one in five AIDS-related deaths globally due to the persistent burden of advanced HIV disease. Moreover, mortality remains high (~50%) in low-resource settings.

Article Synopsis
  • Amphotericin B is the primary treatment for severe fungal infections, and a new less-toxic oral formulation called lipid nanocrystal (LNC) amphotericin has been developed for potential use.
  • A clinical trial tested LNC amphotericin against traditional intravenous amphotericin for treating cryptococcal meningitis in HIV patients, focusing on safety, efficacy, and survival rates.
  • Results showed that the oral formulation had comparable effectiveness and was associated with fewer severe side effects compared to intravenous treatment, suggesting it could be a safer alternative for patients.

Article Synopsis
  • Cryptococcal meningitis is a significant cause of death in AIDS patients, and understanding the reasons for symptom recurrence is challenging.
  • A study in Uganda classified recurrent cases into categories like microbiological relapse and paradoxical immune reconstitution inflammatory syndrome (IRIS), enrolling 724 participants.
  • Findings showed that patients with relapse had lower immune markers (CD4 and cerebrospinal fluid white blood cell counts) compared to those with IRIS, with higher mortality rates associated with the first episodes of meningitis and relapses.
  • The results suggest that monitoring these lab values can guide early antifungal treatment.

  • Sodium abnormalities, particularly hyponatremia (low sodium levels), are common in central nervous system infections like cryptococcal meningitis (CM) and may affect patient outcomes.
  • In a study of 816 HIV-infected Ugandan adults with CM, 91% had sodium measurements, revealing that significant proportions had severe (16%) or moderate (26%) hyponatremia.
  • Hyponatremia was linked to worse clinical indicators and nearly doubled the risk of 2-week mortality, indicating a need for improved management strategies for sodium imbalances in CM.

Article Synopsis
  • A study in Uganda assessed the outcomes of HIV patients with cryptococcal meningitis, comparing those diagnosed through routine CrAg screening to those with symptomatic meningitis who went directly to the hospital.
  • Results indicated that CrAg-screened individuals had significantly lower 14-day mortality rates (12% vs 21%) and better overall health indicators, such as lower altered mental status and CSF burden.
  • The findings suggest that CrAg screening allows for earlier detection of cryptococcal meningitis, leading to better survival outcomes compared to those diagnosed without screening.
