Round ligament management during minimally invasive groin hernia repair in women: a systematic review and meta-analysis.

BACKGROUND: Female sex has been associated with worse outcomes after groin hernia repair (GHR), including a higher rate of chronic pain and recurrence. Most of the studies in GHR are performed in males, and the recommendations for females extrapolate from these studies, even though females have anatomy intricacies. The round ligament of the uterus (RLU) is associated with pelvic stabilization and plays a role in sensory function. Transection of the RLU during GHR is controversial as it can allow easier mesh placement but can favor genitourinary complications and chronic pain. As no previous meta-analysis compared preserving versus transecting the RLU during minimally invasive (MIS) GHR, we aim to perform a systematic review and meta-analysis evaluating surgical outcomes comparing the approaches. METHODS: Cochrane Central, Embase, and PubMed databases were systematically searched for studies comparing transection versus preservation of the RLU in MIS groin hernia surgeries. Outcomes assessed were operative time, bleeding, surgical site events, hospital stay, chronic pain, paresthesia, recurrence rates, and genital prolapse rates. Statistical analysis was performed using RevMan 5.4.1. Heterogeneity was assessed with I2 statistics. A review protocol for this meta-analysis was registered at PROSPERO (CRD 42023467146). RESULTS: 1738 studies were screened. A total of six studies, comprising 1131 women, were included, of whom 652 (57.6%) had preservation of the RLU during MIS groin hernia repair. We found no statistical difference regarding chronic pain, paresthesia, recurrence rates, and postoperative complications. We found a longer operative time for the preservation group (MD 6.84 min; 95% CI 3.0-10.68; P = 0.0005; I2 = 74%). CONCLUSION: Transecting the RLU reduces the operative time during MIS GHR with no difference regarding postoperative complication rates. Although transection appears safe, further prospective randomized studies with long-term follow-up and patient-reported outcomes are necessary to define the optimal management of RLU during MIS GHR.

Transinguinal preperitoneal (TIPP) versus Lichtenstein for inguinal hernia repair: a systematic review and meta-analysis.

PURPOSE: We aimed to perform a systematic review and meta-analysis comparing postoperative outcomes in inguinal hernia repair with TIPP versus Lichtenstein technique. METHODS: Cochrane Central, Scopus, and PubMed were systematically searched for studies comparing TIPP and Lichtenstein´s technique for inguinal hernia repair. Outcomes assessed were operative time, bleeding, surgical site events, hospital stay, the Visual Analogue Pain Score, chronic pain, paresthesia rates, and recurrence. Statistical analysis was performed using RevMan 5.4.1. Heterogeneity was assessed with I2 statistics and random-risk effect was used if I2 > 25%. RESULTS: 790 studies were screened and 44 were thoroughly reviewed. A total of nine studies, comprising 8428 patients were included, of whom 4185 (49.7%) received TIPP and 4243 (50.3%) received Lichtenstein. We found that TIPP presented less chronic pain (OR 0.43; 95% CI 0.20-0.93 P = 0.03; I2 = 84%) and paresthesia rates (OR 0.27; 95% CI 0.07-0.99; P = 0.05; I2 = 63%) than Lichtenstein group. In addition, TIPP was associated with a lower VAS pain score at 14 postoperative day (MD - 0.93; 95% CI - 1.48 to - 0.39; P = 0.0007; I2 = 99%). The data showed a lower operative time with the TIPP technique (MD - 7.18; 95% CI - 12.50, - 1.87; P = 0.008; I2 = 94%). We found no statistical difference between groups regarding the other outcomes analyzed. CONCLUSION: TIPP may be a valuable technique for inguinal hernias. It was associated with lower chronic pain, and paresthesia when compared to Lichtenstein technique. Further long-term randomized studies are necessary to confirm our findings. Study registration A review protocol for this meta-analysis was registered at PROSPERO (CRD42023434909).

What happens when you are not on social networks? A survey among middle-school teens in Switzerland.

AIM: The aim of the study was to describe the differences between users and non-users of social networks controlling for explanatory factors. METHODS: Data were drawn from a survey on media and Internet use carried out among 2893 10th graders in Switzerland. Participants were asked whether they were active in 10 different social networks and divided into two groups: Not active (answering no to the 10 networks; n = 176) and Active (answering positively to at least one; n = 2717). The groups were compared on sociodemographic, health, and screen-related variables. All variables significant in the bivariate analysis were included in a backward logistic regression. RESULTS: The backward logistic regression revealed that inactive participants were more likely to be males, younger, to live in an intact family, and to assess their screen time as below average, and less likely to practice extracurricular sport, to spend ≥4 h of screen time per day, to be around their smartphone at all times, to have parental rules about Internet content, or to discuss Internet use with parents. CONCLUSION: Most young adolescents use social networks. However, this activity does not seem to be associated with academic problems. Therefore, the use of social networks should not be demonized but considered part of their social life.

Analysis of the small chromosomal Prionium serratum (Cyperid) demonstrates the importance of reliable methods to differentiate between mono- and holocentricity.

For a long time, the Cyperid clade (Thurniceae-Juncaceae-Cyperaceae) was considered a group of species possessing holocentromeres exclusively. The basal phylogenetic position of Prionium serratum (Thunb.) Drège (Thurniceae) within Cyperids makes this species an important specimen to understand the centromere evolution within this clade. In contrast to the expectation, the chromosomal distribution of the centromere-specific histone H3 (CENH3), alpha-tubulin and different centromere-associated post-translational histone modifications (H3S10ph, H3S28ph and H2AT120ph) demonstrate a monocentromeric organisation of P. serratum chromosomes. Analysis of the high-copy repeat composition resulted in the identification of two centromere-localised satellite repeats. Hence, monocentricity was the ancestral condition for the Juncaceae-Cyperaceae-Thurniaceae Cyperid clade, and holocentricity in this clade has independently arisen at least twice after differentiation of the three families, once in Juncaceae and the other one in Cyperaceae. In this context, methods suitable for the identification of holocentromeres are discussed.

Is vulnerability associated with substance use? A study among youth in Switzerland.

Adolescence is a period of exploration and experimentation that includes risk behaviors such as substance use. Adolescents living in a situation of vulnerability could be more prone to using substances. In this cross-sectional study, we aimed to evaluate the association between the level of vulnerability and substance use considering explanatory factors. Data were obtained from the first wave of the GenerationFRee project (http://www.generationfree.ch), a longitudinal study based on data collected yearly between 2014 and 2019 on youth aged 15-24 years in high schools and professional schools. The sample included 5179 participants. We designated four risk behaviors: current tobacco smoking, alcohol misuse, cannabis use, and other illegal drug use. We defined vulnerability based on three criteria: the relationship with parents, school performance, and the family socioeconomic status (SES). According to this definition, participants were divided into three groups: no vulnerability, moderate vulnerability, and high vulnerability. Each substance was compared by vulnerability level and controlled with explanatory factors such as age, gender, perceived health, emotional well-being, academic track, nationality, living with parents, residence, family structure, money earned, and perceived personal financial situation. The results show that all substances except alcohol misuse are associated with vulnerability at the bivariate level. All the explanatory factors were also significant with the exception of academic track and amount of money earned per month. In the multinomial regression, for the moderate- and high-vulnerability groups, cannabis use was the only behavior that remained significant. In conclusion, this study shows the association between level of vulnerability and substance use, especially cannabis use. The results also demonstrate the complexity around vulnerability and how the interaction with social aspects influences vulnerability. Youths presenting familial, educational, or financial problems need to be especially screened for substance use by healthcare providers.

Identification of passion fruit (Passiflora edulis) chromosomes using BAC-FISH.

Passiflora edulis, the yellow passion fruit, is the main crop from the Passiflora genus, which comprises 525 species with its diversity center in South America. Genetic maps and a BAC (bacterial artificial chromosome) genomic library are available, but the nine chromosome pairs of similar size and morphology (2n = 18) hamper chromosome identification, leading to different proposed karyotypes. Thus, the aim of this study was to establish chromosome-specific markers for the yellow passion fruit using single-copy and repetitive sequences as probes in fluorescent in situ hybridizations (FISH) to allow chromosome identification and future integration with whole genome data. Thirty-six BAC clones harboring genes and three retrotransposons (Ty1-copy, Ty3-gypsy, and LINE) were selected. Twelve BACs exhibited a dispersed pattern similar to that revealed by retroelements, and one exhibited subtelomeric distribution. Twelve clones showed unique signals in terminal or subterminal regions of the chromosomes, allowing their genes to be anchored to six chromosome pairs that can be identified with single-copy markers. The markers developed herein will provide an important tool for genomic and evolutionary studies in the Passiflora genus.

Transition from paediatric to adult care: what makes it easier for parents?

OBJECTIVE: To assess differences between parents of adolescents with chronic illness (CI) going through a self-reported easy or difficult transfer. METHODS: Seventy-two parents of CI youths who had already transferred to adult care were divided according to whether they considered that the transfer had been easy (n = 45) or difficult (n = 27). We performed a bivariate analysis comparing both groups and variables with a significance level < .1 were included in a logistic regression. Results are presented as adjusted odds ratio (aOR). RESULTS: Over one third of parents (27/72) reported a difficult transfer. At the multivariate level, higher socioeconomic status (aOR: 7.74), parents feeling ready for transfer (aOR: 6.54) and a good coordination between teams (aOR: 7.66) were associated with an easy transfer. CONCLUSIONS: An easy transfer for parents is associated with feeling ready and considering that the coordination between teams is good. Health providers should consider these requisites for a successful transfer.

The relation between internet use and overweight among adolescents: a longitudinal study in Switzerland.

OBJECTIVE: This longitudinal study aimed to investigate the characteristics and predictive risk factors of overweight among adolescents. The hypothesis was that baseline overweight predicted most overweight over time compared to other factors, especially excessive internet use. SUBJECTS: A sample of 621 youths were followed from age 14 (T0 Spring 2012) to age 16 (T1 Spring 2014) in Switzerland. Participants were divided into two groups according to their weight at the final assessment: overweight and non-overweight. At T0, participants reported demographic, health, substance use and internet use data. A logistic regression was performed to assess the explanatory variables of overweight at T1. Data are presented as adjusted odds ratios (aORs) with 95% confidence interval. RESULTS: The 2-year evolution showed a net BMI increase of 4.8%. Overweight adolescents were significantly more likely to be male, to live in an urban area, to be on a diet and to report using the internet more than 2 h per day on weekends at T0. However, with the addition of baseline overweight, only the excessive use of internet on weekends remained as an explanatory variable. An adolescent who was already overweight at T0 had a more than 20-fold risk (aOR 21.04) of being overweight 2 years later. Moreover, among adolescents becoming overweight between T0 and T1, internet use did not show any significant effect. CONCLUSION: The risk of being overweight is mostly influenced by weight status at baseline compared to excessive internet use. Thus, our results do not confirm the negative effect of internet on healthier activities. Internet use could at most reinforce an already existing risk of being overweight.

Preference of patient information leaflets over standard drug monographs by patients prescribed hydrochlorothiazide, nifedipine and enalapril.

Standard drug monographs (SDMs) have been described as deficient in providing information in a manner simplified enough for patient reading. The aim of this study was to design patient information leaflets for hydrochlorothiazide, nifedipine and enalapril with content indicated by patients as relevant and to evaluate them against the SDM. Patient information leaflet (PIL) for each drug was designed to contain information on name, use of drug, how it works, how it is to be taken, common side effects, storage, missed dose action, things to avoid and when to contact the physician. Appropriateness was assessed by 10 practising pharmacists. For each drug, 40 patients were recruited, of which 20 were given SDM and 20 PIL. The knowledge of each participant was examined before and after exposure to SDM or PIL, as well as opinion on ease of reading and attractiveness using Pearson s Chi-square analysis. The results showed that both SDM and PIL improved knowledge of common side effects when compared with responses before exposure (chi2 = 24.26 for SDM and 27.64 for PIL, p < 0.001) with no difference between the groups. Respondents receiving PILs were better able to recall "things to avoid" after exposure to PIL (chi2 =10.85, p < 0.001). After exposure to SDM or PIL, the respondents who received PIL were more aware of when to contact the physician, compared to the SDM group (chi2 = 8.41, p < 0.01). When compared with SDM, respondents receiving PIL were more likely to indicate that PIL was easy to read (chi2 = 20.00, p < 0.001), attractive (chi2 = 12.45, p < 0.001) and they were more likely to recommend distribution of their reading material to other patients (chi2 = 22.11, p < 0.001). We conclude that there is benefit in designing information leaflets that simplify language and medication information contained in SDMs, including better understanding of precautions to take while on medication and when to consult physicians.

Preference of patient information leaflets over standard drug monographs by patients prescribed hydrochlorothiazide, nifedipine and enalapril / Preferencia por los prospectos de información al paciente en lugar de las monografías estándar sobre medicamentos, por parte de los pacientes a quienes se les ha prescrito hidroclorotiazida, nifedipina y analapril

Las monografías de medicamentos estandarizadas se han considerado deficientes a la hora de proporcionar información de manera suficientemente simple para que el paciente pueda entenderlas. El objetivo de este estudio fue disenar prospectos con información sobre la hidroclorotiazida, la nifedipina y el analapril con contenidos indicados como relevantes por los pacientes, y evaluarlos en comparación con las monografías estandarizadas de medicamentos (MEM). El prospecto de información para el paciente (PIP) fue disenado de modo que apareciera información sobre el nombre del medicamento, su uso, modo de operar, manera de tomarse, efectos secundarios comunes, almacenamiento, qué hacer en caso de perder una dosis, cosas que deben evitarse, y cuando debe contactarse el médico. Se evaluó la adecuación por parte de 10 farmacéuticos practicantes. Para cada medicamento, se reclutaron 40 pacientes, a 20 de los cuales se les dio monografías (MEM), en tanto que a 20 se les ofreció prospectos (PIP). El conocimiento de cada participante se examinó antes y después de la exposición a MEM o PIP, así como la opinión en cuanto a facilidad de lectura y grado de atracción, usando el análisis del Chi-cuadrado de Pearson. Los resultados mostraron que tanto MEM como PIP mejoraron el conocimiento sobre los efectos secundarios comunes, cuando se hacía una comparación con las respuestas antes de la exposición (χ² = 24.26para MEMy 27.64para PIP, p < 0.001) sin diferencia entre los grupos. Los encuestados que recibieron prospectos pudieron recordar mejor las "cosas a evitar" luego de la exposición a PIP (χ² =10.85, p < 0.001). Después de la exposición a MEM o PIP, los encuestados con PIP tenían mayor conciencia en cuanto a cuando contactar a un médico, en comparación con el grupo MEM (χ² = 8.41, p < 0.01). Cuando se les comparó con el grupo MEM, los encuestados que recibieron PIP mostraron por una parte mayor probabilidad de indicar que PIP era más fácil de leer (χ² = 20.00, p < 0.001) y atractivo (χ² = 12.45, p < 0.001), y por otra, una mayor tendencia a recomendar la distribución de su material de lectura a otros pacientes (χ² = 22.11, p < 0.001). Se llegó a la conclusión de que es beneficioso disenar prospectos que simplifiquen el lenguajey la información médica contenida en las monografias estándar del medicamento, incluyendo una mejor comprensión de las precauciones a tomar mientras se está bajo medicación, y sobre cuándo consultar al médico.
