ABSTRACT

Monitoring soil quality index (SQI) and soil organic carbon (SOC) stock status of the Western Ghats (WG) forests in India is crucial for providing vital ecosystem services alongside sustainable forest management practices. However, comprehensive profile data on SQI and SOC stock across different forest types under WG forests are limited. The study evaluated SQI and SOC stock under three forest types, i.e. tropical wet evergreen (TWE), tropical semi-evergreen (TSE), and tropical moist deciduous (TMD) across WG in Karnataka. SQI was assessed using principal component analysis with two indexing approaches and scoring methodologies, with weightage indexing through nonlinear scoring functions (NLSF) showing superiority over other methodologies. TMD forests exhibited the highest SQI, followed by TWE and TSE, while the lowest was observed in Rippon Pet RF (0.36 surface, 0.28 control section), primarily due to limitations in organic carbon and clay content. SOC stock mirrored SQI trends (TMD > TWE > TSE), with the highest values in Kollegal RF (339.3 MG ha^-1) and lowest in Rippon Pet RF (102.5 MG ha^-1). Although SOC and SQI were established to be ideal indicators for dynamic ecosystem services (ESs), high OC content in surface soils of Poomale NF induces pedogenic acidification and Al toxicities, indicating potential forest soil degradation. Significant correlation with control section SQI and SOC (p < 0.05) emphasises monitoring subsurface soil status to identify soil degradation, sustainable forestry practices, and complex ESs in forest systems.

ABSTRACT

BACKGROUND: Glossopharyngeal neuralgia (GN) is a rare pain syndrome often underdiagnosed. This study aimed to assess the challenges in diagnosing GN and identify patients at risk of misdiagnosis.

METHODS: Between 2010 and 2019, nine patients underwent microvascular decompression (MVD) of the glossopharyngeal nerve at two tertiary care hospitals. A retrospective analysis examined symptom characteristics, time to correct diagnosis, operative technique, and clinical outcomes. Barrow Neurological Institute (BNI) pain scores were assessed before surgery and on follow-up.

RESULTS: Six women and three men, aged 55 ± 14.3 years, with unilateral GN were included. Pain was predominantly in the ear (otalgic type) in four patients (44.4%), the pharynx or base of the tongue (pharyngeal type) in four (44.4%), and mixed in one (11.1%). Five patients reported pain radiating to the mandible, all initially misdiagnosed with trigeminal neuralgia (TN) and treated for 2.4(± 3.1) years before presenting to our institution. One case resulted in MVD of the trigeminal nerve and subsequent thermocoagulation of the Gasserian ganglion due to persistent pain. The correct diagnosis of GN was established later in patients with otalgic or mixed pain (3.8 ± 3.4 years) compared to those with pharyngeal pain (0.5 ± 1.0 years), showing a trend (U = 17.0, p = 0.07). There was a significant association between pain radiation to the mandible and misdiagnosis (x² = 9.00, p = 0.003). Endoscopically assisted MVD via the median suboccipital subtonsillary approach was performed, resolving neurovascular conflicts with the PICA (9/9) and vertebral artery (3/9). Follow-up after 15.7(± 18.2) months showed significant pain reduction according to the BNI (preoperative BNI = 5.0 ± 0.0, postoperative BNI = 1.7 ± 1.0,t (8) = 10,CI [1.6-5.1], p < 0.001). No permanent surgery-related deficits occurred.

CONCLUSION: Patients with GN, especially those with predominant otalgic pain and pain radiating to the mandible, are at higher risk of misdiagnosis due to similarities with TN. Despite the rarity of GN, increased awareness of its various pain manifestations may lead to earlier correct diagnoses, which is crucial for surgical treatment.

ABSTRACT

Benign prostatic hyperplasia (BPH) affects up to 80% of men by age 80, with large-gland BPH often treated by simple prostatectomy (SP). This technique significantly improves symptoms but is associated with high rates of complications such as transfusions and infections. Minimally invasive techniques, including robotic-assisted laparoscopic simple suprapubic prostatectomy (RALSP), have emerged as alternatives. This study reports on 162 patients who underwent RALSP from May 2018 to June 2023. The mean age of the patients was 69 years, mean prostate volume 144.8 cm³, mean robot time 78.7 min, and mean blood loss 183.1 mL. Results demonstrated significant improvements in the results: prostate volume (mean decrease from 144.8 to 26.6 cm³), mean PSA level decreased from 7.8 to 0.8 (p < 0.0001), mean IPSS decreased from 23.0 to 4.4 (p < 0.0001), and mean uroflowmetry increased from 6.3 to 22.6 ml/s (p < 0.0001). No patient experienced worsening erectile function after surgery. All patients showed absence of stress urinary incontinence within 3 months. Catheterization time decreased from 4.2 to 2.6 days over the study period. The postoperative complication rate was 2.29%, with no need for surgical reintervention for complications. While RALSP showed promising results, further prospective studies are needed to compare it with other techniques. This study highlights RALSP as a viable minimally invasive option for treating large-volume BPH, offering reduced recovery times and fewer complications.

ABSTRACT

Recent work has demonstrated that exposure to artificial light at night (ALAN) may alter mosquito feeding behavior and so must be considered a moderator of vector-borne disease transfer. Anopheles funestus mosquitoes are a primary malaria vector in sub-Saharan Africa, but no study to date has tested the impact of ALAN on their feeding behavior. Here we test if the exposure to commonly used household lights (compact fluorescent lights, light-emitting diodes, and incandescent lights) alters Anopheles funestus feeding. Mated, unfed female mosquitoes were exposed to a light treatment, at the onset of darkness, followed by a blood-feeding assay. The light treatments consisted of a 30-min light pulse of one of the three household lights, each in individual experimental containers, versus controls. All three household lights resulted in a reduction in the percentage of females taking a blood meal, but only mosquitoes exposed to incandescent light showed a statistically significant reduction in feeding of 19.6% relative to controls which showed a 42.8% feeding rate. Our results suggest that exposure to some household lights during the night may have an immediate inhibitory effect on Anopheles funestus feeding. By helping identify which light types lead to a suppression of feeding, the findings of this study could provide insight necessary to design household lights that can help minimize mosquito feeding on humans.

ABSTRACT

PURPOSE: To characterize patients with cytomegalovirus (CMV) retinitis and identify risk factors for retinal detachment (RD) and mortality in this Taiwanese patient population.

METHODS: This retrospective study included patients diagnosed with CMV retinitis between 2007 and 2019. The diagnosis was confirmed through aqueous polymerase chain reaction (PCR). Relevant data were collected from the Chang Gung Research Database. Univariate Cox regression was performed to identify the associations of RD and mortality risks with various patient characteristics, including demographic features, comorbidities, laboratory results, and medication use patterns.

RESULTS: In total, 32 patients with CMV retinitis were included. Among these patients, 78.1% had an immunocompromised status, including 56.3% with high-dose systemic steroid use, 21.9% with HIV infection, 12.5% with hematologic malignancy, and 9.4% with renal transplantation. Approximately 21.9% of patients had RD 2.4 ± 2.1 months after CMV retinitis diagnosis, and 34.4% died within 6.2 [4.2, 38.2] months after diagnosis. Patients with RD had a statistically significant, but likely not clinically significant, later initiation of anti-CMV medications compared to their non-RD counterparts (8 [5, 23] days vs. 2 [1, 11] days, p = 0.039). Mortality was significantly associated with older age (hazard ratio [HR]: 1.06; 95% confidence interval [CI]: 1.02-1.10), hematologic malignancy (HR: 5.92; 95% CI: 1.44-24.37), and positivity for CMV on blood PCR (HR: 4.93; 95% CI: 1.49-16.35).

CONCLUSION: Our study suggests that older age, hematologic malignancy, and positivity for CMV on blood PCR are risk factors for mortality in patients with CMV retinitis.

KEY MESSAGES: What is known Cytomegalovirus (CMV) retinitis is the predominant sight-threatening opportunistic ocular infection in patients with acquired immunodeficiency syndrome (AIDS). What is new In the era of highly active antiretroviral therapy for AIDS, the majority of CMV retinitis patients are those receiving immunomodulatory therapy for underlying diseases. Older age, hematologic malignancy, and positive blood polymerase chain reaction for CMV are potential risk factors for mortality in patients with CMV retinitis.

ABSTRACT

1H-MRS investigators studying brain metabolite concentrations often attribute biological significance to correlations between calculated metabolite values within the same voxel. A recent report in this journal provides a valuable perspective on how statistical non-independence of such values can undermine biological interpretations of their correlations. However, careful examination of this issue suggests their critical analysis does not go far enough. Hong et al. claim that appropriate water normalization, unlike creatine normalization, eliminates the problem of spurious correlation. Both logical and empirical considerations show this is not the case. Correlations between water-normalized metabolite values are also prone to substantial spurious correlations.

ABSTRACT

OBJECTIVE: Despite advances in the treatment of Chronic Inflammatory Rheumatic Disease (CIRD), pain remains a significant burden for patients and doctors. This study explored the prevalence and associated factors of central sensitization (CS) in patients with CIRD.

METHODS: This is a cross-sectional study that included patients with CIRD followed at the University Hospital Center in Tangier. Sociodemographic and clinical data were collected. Nociceptive pain was assessed by the Visual Analogue Scale (VAS), disease activity by DAS-28 and ASDAS, and CS by the validated Moroccan version of the Central Sensitization Inventory part A (CSI-A). The Pain Catastrophizing Scale (PCS) was used to assess pain-related catastrophic thoughts, and the PHQ-9 (Pain Health Questionnaire) was used to determine the severity of depressive symptoms.

RESULTS: We included 189 patients; 107 (56.61%) had rheumatoid arthritis. The median duration of evolution of CIRD was 8 years, and the mean age was 47.49 ± 13.70 years, and 75.7% were women. The mean pain VAS was 4.77+-2.76, and 37.6% of patients were in remission. The mean central sensitization score was 37.42+- 16.75, with 44.9% having a CSI score≥40. In univariate and multivariate analysis, our study showed that central sensitization is associated with pain severity (β = 1.945(0.050-1.916), p = 0.039) and depression (β = 1.790(1.221-2.154), p ≤0.001)(8). A statistically significant correlation was found between the CSI-A score and pain VAS (r = 0.32, p <0.001).

CONCLUSION: Our study showed that almost half of our patients with CIRD had CS. The main factors associated with CS in our patients were pain severity and depression. We also found a significant correlation between pain VAS and CSI.

ABSTRACT

BackgroundSweden reached the UNAIDS 90-90-90 target in 2015. It is important to reassess the HIV epidemiological situation due to ever-changing migration patterns, the roll-out of PrEP and the impact of the COVID-19 pandemic.AimWe aimed to assess the progress towards the UNAIDS 95-95-95 targets in Sweden by estimating the proportion of undiagnosed people with HIV (PWHIV) and HIV incidence trends.MethodsWe used routine laboratory data to inform a biomarker model of time since infection. When available, we used previous negative test dates, arrival dates for PWHIV from abroad and transmission modes to inform our incidence model. We also used data collected from the Swedish InfCareHIV register on antiretroviral therapy (ART).ResultsThe yearly incidence of HIV in Sweden decreased after 2014. In part, this was because the fraction of undiagnosed PWHIV had decreased almost twofold since 2006. After 2015, three of four PWHIV in Sweden were diagnosed within 1.9 and 3.2 years after infection among men who have sex with men and in heterosexual groups, respectively. While 80% of new PWHIV in Sweden acquired HIV before immigration, they make up 50% of the current PWHIV in Sweden. By 2022, 96% of all PWHIV in Sweden had been diagnosed, and 99% of them were on ART, with 98% virally suppressed.ConclusionsBy 2022, about half of all PWHIV in Sweden acquired HIV abroad. Using our new biomarker model, we assess that Sweden has reached the UNAIDS goal at 96-99-98.
