Published: August 2024

AIM: To investigate the incidence and high-risk factors associated with the surgical treatment of acute female pelvic inflammatory disease (PID).
METHODS: A retrospective analysis was conducted on all inpatients diagnosed with acute female PID, encompassing conditions such as endometritis, salpingitis, tubo-ovarian abscess, ovarian abscess, and pelvic peritonitis, at Dongyang Hospital of Wenzhou Medical University from January 2013 to December 2021. Patients were categorized into two groups: the surgery group (n = 58) and the non-surgery group (n = 399), based on the necessity of surgical intervention (refer to Materials and Methods for surgical indications). Collected data included patient demographics (age, body mass index (BMI)), comorbidities (hypertension, diabetes mellitus), initial laboratory findings upon admission (white blood cell count, absolute neutrophil count, hemoglobin, platelet count, blood urea nitrogen/creatinine, prothrombin time (PT), international normalized ratio (INR), fibrinogen, albumin), surgical records, and postoperative pathology. Univariate and multivariate logistic regression analyses were conducted to ascertain the risk factors associated with the surgical treatment of acute female PID.
RESULTS: Out of 457 hospitalized patients with acute female PID, 58 cases (12.7%) required surgical intervention. Univariate and multivariate logistic regression analyses indicated that advancing age correlated with an increased likelihood of surgical intervention in women with acute PID (odds ratio (OR) = 1.052, 95% Confidence Interval (CI) 1.022–1.082, p = 0.001). Additionally, lower serum albumin levels upon admission were associated with a heightened risk of surgery (OR = 0.913, 95% CI 0.859–0.970, p = 0.003), while elevated fibrinogen levels amplified the risk of surgical intervention in these patients (OR = 1.193, 95% CI 1.008–1.411, p = 0.04).
CONCLUSIONS: Elderly women diagnosed with acute PID, especially those presenting with abscess formation, should undergo prompt surgical intervention if they display high-risk factors such as low albumin levels and elevated fibrinogen levels upon admission.

Published: August 2024

Endovascular aneurysm repair (EVAR) has emerged as the preferred treatment for abdominal aortic aneurysm (AAA), offering advantages such as reduced mortality, faster recovery, and fewer complications compared to open repair (OR). However, concerns persist regarding long-term durability, and the need for reinterventions. Among all reported EVAR complications, endograft collapse poses a significant challenge, particularly when presenting with acute lower limb ischemia (ALI).
The aim of this report is to describe two cases of non-dissection-related abdominal endograft collapse manifesting as ALI, requiring urgent intervention, emergent conversion to OR and complete endograft removal.

Published: August 2024

AIM: This study aimed to evaluate the hypothesis that the utilization of percutaneous screw guides enhances the precision of screw placement in the surgical fixation of talar fractures.
METHODS: Computed tomography (CT) scans of ankle joints were obtained from 40 healthy adults and 10 cadaveric specimens between April 2019 and August 2020 at Ningbo No. 6 Hospital. The acquired CT data were imported into Materialise Interactive Medical Image Control System (MIMICS) software for processing. Three-dimensional (3D) digital models of the ankle joints were reconstructed, and relevant anatomical parameters were measured. A percutaneous screw guide (PSG) was designed and fabricated to facilitate accurate screw placement in the posterior talar process. Ten eligible cadaveric ankle joints were selected for further analysis and their 3D models were reconstructed using the MIMICS software. Screw trajectory parameters were then measured and analyzed based on these cadaveric models, forming the model group for comparative analyses. Ten cadaveric specimens were utilized in this study, equally divided into two groups: a guider group (n = 5) and a free-hand group (n = 5). In the guider group, talar posterior process screws were inserted using percutaneous screw guidance. In the free-hand group, screws were inserted into the talar posterior process without guidance. Post-operative CT scans were performed on all specimens. The following parameters were quantitatively compared between the two groups: screw trajectories, entry point distances in specimens with preselected screws, entry point distance trajectories in the 3D model, operation time, frequency of fluoroscopic imaging, and number of drilling attempts.
RESULTS: Following the generation of the 3D models from 10 cadavers, a virtual screw was digitally inserted into each model. In the model group, the preselected screw trajectory was oriented towards the medial aspect of the talar neck base, with a cephalad inclination angle (CIA) of 3.1° ± 1.5° in the transverse~plane and a medial diverge angle (MDA) of 12.0° ± 1.4° in the coronal plane. The CIA and MDA of the screw trajectory in the guider group were 2.1° ± 1.7° and 11.2° ± 1.6°, respectively, whereas the CIA and MDA in the free-hand group were 6.0° ± 2.2° and 18.8° ± 1.6°, respectively. Statistical analysis revealed significant differences in both CIA and MDA between the two groups (p < 0.05). Furthermore, the guider group yielded superior outcomes in terms of entry point distance, operation time, fluoroscopic exposure time, and number of drilling attempts compared to the free-hand group (p < 0.05).
CONCLUSIONS: Percutaneous screw guidance can improve the accuracy and safety of the posterior process of the talar screws, which can be feasible for percutaneous fixation. Further studies are required to confirm the efficacy and clinical outcomes of percutaneous screw guidance.

Published: August 2024

AIM: Acute appendicitis is a common disease in the elderly. Exploring a suitable anesthesia method is crucial in promoting postoperative recovery in elderly patients. Therefore, this study aimed to investigate the clinical effect of intraspinal anesthesia in elderly patients with appendicitis.
METHODS: This study included the clinical data of 217 elderly patients with acute appendicitis who underwent laparoscopic appendectomy (LA) at Tianjin Hospital of Tianjin University from January 2022 to January 2023. After excluding 8 patients who did not meet the inclusion criteria, the data from 209 patients were retrospectively analyzed. Based on the different anesthesia methods, the study participants were divided into a reference group (n = 106) and a study group (n = 103). We compared the heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), blood oxygen saturation (SaO2), operation duration, hospitalization costs, discharge time, postoperative adverse reactions, inflammatory factor levels, Visual Analogue Scale (VAS) score, recovery time of intestinal peristalsis, anal exsufflation time, out-of-bed time, and incidence of postoperative complications between the two experimental groups.
RESULTS: We observed that the study group exhibited higher levels of HR, RR, SBP, DBP, and SaO2 compared to the reference group (p < 0.001). However, there was no difference in operation time between the two groups (p > 0.05). The study group showed lower hospitalization cost and shorter discharge time than the reference group (p < 0.001). Similarly, the study group had lower incidence of postoperative adverse reactions than reference group (p < 0.05). There were no significant differences in the levels of C-reactive protein, interleukin-6, and tumor necrosis factor-α between the two groups before and after surgery (p > 0.05). Furthermore, the study group had a lower VAS score compared to the reference group at 3 h, 6 h and 12 h after surgery (p < 0.001). The recovery time of intestinal peristalsis, anal exsufflation time, and out-of-bed time in the study group were substantially shorter than the reference group (p < 0.001). Additionally, there was no difference in the incidence of postoperative complications between the two groups within 1 year after surgery (p < 0.001).
CONCLUSIONS: Intraspinal anesthesia, as a safe anesthesia method, can reduce the discharge time of elderly patients with acute appendicitis who underwent LA, and reduce the occurrence of adverse reactions, and is beneficial for postoperative recovery.

Published: August 2024

AIM: The indications for performing retrograde intrarenal surgery (RIRS) have increased. However, no comparative studies have been conducted on the treatment of staghorn renal calculi using RIRS and percutaneous nephrolithotomy (PCNL). We aimed to compare the effectiveness and safety of RIRS and PCNL as treatments for staghorn renal calculi.
METHODS: We conducted a retrospective analysis of patients with staghorn renal calculi who underwent either PCNL or RIRS at our hospital from January 2021 to July 2023. Patients with staghorn renal calculi and renal malformation, as well as those with interrupted treatment or irregular follow-up, were excluded from the study. We compared the perioperative outcomes and complications between the groups.
RESULTS: Fifty patients were included in the RIRS group, whereas 48 patients were included in the PCNL group. 1. No significant differences were observed between the groups regarding the number of complete staghorn calculi, stone size, age, sex, or other demographic characteristics. 2. RIRS was associated with a shorter postoperative hospitalization time (2.14 ± 0.76 vs. 5.15 ± 1.98 days, p < 0.001). 3. RIRS was associated with a decrease in hemoglobin (0.1 [0, 0.2] vs. 0.65 [0.4, 1] g/dL, p < 0.001) and a lower pain score (1 [1, 2] vs. 2 [1, 3], p = 0.008). 4. Compared with PCNL, RIRS did not significantly differ in terms of the 1-stage stone-free rate (50% vs. 66.67%, p = 0.095) or total stone-free rate (84% vs. 89.58%, p = 0.415). 5. The overall complication rate was lower in the RIRS group (10% vs. 16.67%, p = 0.331).
CONCLUSIONS: Compared with PCNL, RIRS can reduce bleeding and overall complications, shorten the hospitalization time, and achieve satisfactory stone-free rate. As a result, RIRS can be considered an alternative treatment option for staghorn renal calculi.
L’agriculture urbaine et périurbaine au Brésil
Authors: Gravel Nathalie , Lemieux Josée 
Published: August 2024

Même si le Brésil a inclus l’agriculture urbaine dans son programme de lutte contre la faim, les obstacles à son déploiement, à l’entretien et à son maintien dans le temps sont encore nombreux. Plusieurs métropoles brésiliennes ont élaboré des plans d’appui à l’agriculture urbaine dans une perspective d’atteinte des objectifs de durabilité sans toutefois mettre en place des politiques publiques ayant des effets facilitateurs. Les questions auxquelles cet article tente de répondre sont : Quelle marge de manoeuvre possèdent les jardiniers urbains pour mener à bien leurs projets et influencer les politiques publiques municipales d’agriculture urbaine ? Et quel est l’avenir de l’agriculture urbaine et périurbaine (AUP) dans les métropoles brésiliennes ? Le potentiel de pérennisation de l’AUP a été étudié dans les métropoles de São Paulo, Florianópolis et Salvador de Bahia. Nous avançons que l’avenir de l’AUP au Brésil dépendra de la capacité des acteurs à négocier et élaborer des outils et politiques publiques à l’échelle municipale. Les processus de négociation de l’accès à l’espace public sur l’échiquier urbain seront analysés, ainsi que les gains réalisés dans chacune des villes, par le biais de la théorie de la régulation sociale.
Digitalisation et gestion des
destinations touristiques : confrontation entre théories et réalités de
terrain
Authors: Toumia Roxane , Cloquet Isabelle 
Published: August 2024

La digitalisation du secteur touristique
soulève plusieurs questionnements quant à l’adaptation aux nouvelles formes de
technologies numériques. Cet article vise à s’interroger en profondeur sur les
dimensions de gestion et de gouvernance des destinations touristiques, au regard
de la « transition digitale », réelle ou perçue, opérée dans le secteur. Alors
que la littérature scientifique en tourisme intègre davantage de questions
relatives aux nouvelles technologies, notamment en faisant référence aux
destinations dites « intelligentes » (smart tourism
destination), le présent article propose de se distancier de ces notions et
de la vision techno-centrée qu’elles induisent. À travers le cas d’étude de la
Région de Bruxelles-Capitale, en Belgique, nous étudierons comment le modèle de
gestion de la destination se modifie avec la digitalisation du secteur.
Confronter théories et réalités de terrain ont permis de saisir plus finement
les enjeux de la digitalisation pour les acteurs du système touristique
bruxellois. Ces enjeux sont loin d’être circonscrits au seul champ des
technologies, et nous verrons l’étroite relation qu’il semble y avoir entre
digitalisation et enjeux économiques, sociaux et environnementaux d’une
destination.

Proposition d’un modèle logique du volet primaire du curriculum Montessori incluant les facteurs contextuels influant sur sa mise en oeuvre
Authors: Gaudreau Joëlle , Brabant Christine 
Published: August 2024

L’engouement contemporain pour l’approche éducative instaurée par Maria Montessori est indéniable dans les réseaux professionnels et au sein de la communauté scientifique à travers le monde. Le corpus scientifique relatif aux effets de cette approche sur les apprenant⋅e⋅s est prometteur, mais encore exploratoire, sa principale limite méthodologique étant le manque d’évaluation de la fidélité de son implantation dans les milieux scolaires desquels sont tirés les échantillons. Pour contribuer à remédier à ce problème, cette étude propose un modèle logique du volet primaire (6 à 12 ans) du curriculum Montessori incluant les facteurs contextuels influant sur sa mise en oeuvre.
La place du programme dans les pédagogies alternatives : trois conceptions du savoir scolaire chez les enseignants
Authors: Legavre Amélia 
Published: August 2024

Les pédagogies alternatives héritent d’une réputation ambivalente quant à la place qu’elles réservent à la réussite scolaire. L’article analyse trois conceptions du savoir scolaire chez les enseignants qui s’inscrivent dans de telles pédagogies : le savoir en douceur ; le savoir pour questionner ; le savoir selon l’envie. Ces conceptions dépendent du positionnement de chaque enseignant par rapport à deux éléments : 1) la valeur accordée au savoir scolaire comparativement aux autres types de contenus ; 2) la représentation de l’enfant et du degré de contrainte jugé opportun pour son acquisition du savoir scolaire.

Published: August 2024

Background
High dose rate (HDR) image-guided brachytherapy with Cobalt-60 isotope is a relatively recent approach. The aim of the study is to evaluate the clinical and dosimetric parameters in terms of tumour response, bladder, and rectal toxicity in patients undergoing Co-60 HDR brachytherapy.

Materials and Method
All patients were initially treated with chemoradiation (CT-RT) at our center or other referral centers with external beam radiation therapy (EBRT) for a dose of 45 Gy–60 Gy at 1.8-2Gy/fraction (including nodal boost) with concomitant chemotherapy with either cisplatin or carboplatin. Patients were then scheduled for brachytherapy within 1 week after completion of CT-RT and are assessed by local examination. Depending on local examination parameters at the time of brachytherapy they were eligible either for intracavitary brachytherapy (ICBT) or interstitial brachytherapy (ISBT).

Results
The complete response (CR) observed in stage I, II, III, IVA were 60%, 79.4%, 86% and 76.2% respectively. Complete response was seen in patients with mean EQD2 of 78.67 Gy10, 83.33 Gy10, 84.23 Gy10, 85.63 Gy10 in stages I, II, III, IVA respectively. 79.2% of cisplatin-treated patients and 87.5% of carboplatin-treated patients had a complete response indicating that patients treated with either chemotherapy had similar response rates.

Conclusions
According to results obtained from the study we conclude by saying that higher rates of complete response to treatment in cervical cancer is seen in patients with shorter overall treatment time (OTT), shorter interval between end of definitive CT-RT and beginning of brachytherapy and squamous cell histology. The study also noted the trend of increasing mean EQD2 to tumor with increasing stage for achieving complete response. Higher acute bladder and rectal toxicity is seen in patients who received EQD2 of ¿70-90Gy3 and ¿70Gy3 respectively. The study findings suggest that the clinical outcomes and the toxicities are clinically comparable with other radioisotope based HDR brachytherapy treatment.

AbstractLarge uncertainty exists in model projections of the land carbon (C) sink response to increasing atmospheric CO2. Free‐Air CO2 Enrichment (FACE) experiments lasting a decade or more have investigated ecosystem responses to a step change in atmospheric CO2 concentration. To interpret FACE results in the context of gradual increases in atmospheric CO2 over decades to centuries, we used a suite of seven models to simulate the Duke and Oak Ridge FACE experiments extended for 300 years of CO2 enrichment. We also determine key modeling assumptions that drive divergent projections of terrestrial C uptake and evaluate whether these assumptions can be constrained by experimental evidence. All models simulated increased terrestrial C pools resulting from CO2 enrichment, though there was substantial variability in quasi‐equilibrium C sequestration and rates of change. In two of two models that assume that plant nitrogen (N) uptake is solely a function of soil N supply, the net primary production response to elevated CO2 became progressively N limited. In four of five models that assume that N uptake is a function of both soil N supply and plant N demand, elevated CO2 led to reduced ecosystem N losses and thus progressively relaxed nitrogen limitation. Many allocation assumptions resulted in increased wood allocation relative to leaves and roots which reduced the vegetation turnover rate and increased C sequestration. In addition, self‐thinning assumptions had a substantial impact on C sequestration in two models. Accurate representation of N process dynamics (in particular N uptake), allocation, and forest self‐thinning is key to minimizing uncertainty in projections of future C sequestration in response to elevated atmospheric CO2.
Long‐term decrease in the response of midlatitude stations to high‐speed solar wind streams in 1914–2000
Authors: Martini D. , Mursula K. , Orispää M. , Linthe H.‐J. 
Published: March 2015

AbstractWe investigate geomagnetic activity at two high‐latitude, two midlatitude, and two low‐latitude stations of the northern hemisphere and find that the increasing trend of geomagnetic activity in 1914–2000 is considerably lower at the two midlatitude stations (Niemegk and Fredericksburg) than at low‐ or high‐latitude stations. As Niemegk occupies a specific position among geomagnetic stations, serving as the standard station for the K/Ak index derivation, it is crucial to understand the origin and long‐term characteristics of this difference. We show here that geomagnetic activity at the studied midlatitude stations is relatively stronger in the declining phases of the 1 and 2 first solar cycles (15 and 16) than elsewhere, leading to the smaller long‐term trend. We also find that the latitudinal differences in the trends are strongly dependent on local time, being considerably larger in the dawn sector. These differences can be explained by the relatively stronger contribution of high‐speed streams to geomagnetic activity at the particular range of midlatitudes, compared to the stations at lower and higher latitudes.
Low‐salinity water off West Luzon Island in summer

Published: March 2015

AbstractLow‐salinity water with two cores is found off West Luzon Island in the South China Sea (SCS) during summer. A series of salinity observations and model results show that the low‐salinity water begins to appear in June, reaches its lowest salinity in September, and disappears after October. Rainfall associated with the summer monsoon impinging on the Philippine mountain ranges plays an important role in the formation of the low‐salinity water, while upward Ekman pumping of high‐salinity subsurface water caused by the strong winter monsoon is important for its disappearance. Variation in mixed layer depth is responsible for the formation of the two cores of the low‐salinity water, while advection also contributes. The study further demonstrates that the low‐salinity water has considerable interannual variability associated with El Niño‐Southern Oscillation (ENSO): during the summer of the decaying year of an El Niño, an anticyclonic wind anomaly occurs in the SCS. The anticyclonic wind anomaly is associated with a northeasterly anomaly south of 18°N, reducing precipitation and causing salting of the low‐salinity water off West Luzon Island. The situation is reversed during the summer of the decaying year of a La Niña.
