¿Está exenta de consecuencias adversas la perforación iatrogénica de la vesícula biliar durante la colecistectomía laparoscópica electiva?
Authors: Domínguez-Comesaña Elías , Domínguez-Fernández Elías , Domínguez-Fernánde Rubén 
Published: September 2021

Objetivo: Este estudio se llevó a cabo para valorar las consecuencias de la perforación iatrogénica de la vesícula biliar (PIVB), investigando su asociación con complicaciones postoperatorias, uso de antibióticos y drenajes, duración de la cirugía y estancia postoperatoria.Materiales y métodos: Se incluyeron 1.703 pacientes con colecistectomía laparoscópica electiva, divididos en dos grupos: con PIVB (Grupo 1; n=321) y sin PIVB (Grupo 2; n=1382). Se compararon los resultados entre ambos grupos.Resultados: El porcentaje de PIVB fue de 18,85 %. El vertido aislado de bilis ocurrió en 241 pacientes (14,15 %) y el de bilis y cálculos en 80 pacientes (4,64 %). La incidencia de infección del sitio quirúrgico no fue diferente entre ambos grupos. La incidencia de PIVB fue mayor en varones (43,3% vs 31,3%), pacientes con adherencias perivesiculares (17,75% vs 10,5%) y pacientes con diagnóstico histológico de colecistitis aguda (11,52% vs 4,92%). La PIVB se asoció significativamente con mayor duración de la cirugía (77,3 vs 65,4 minutes), mayor uso de drenajes y antibióticos y mayor estancia postoperatoria. No hubo complicaciones tardías.Discusión y Conclusión: La PIVB no aumenta la incidencia de infección, pero se asocia con un mayor uso de drenajes y antibióticos, mayor duración de la cirugía y mayor estancia postoperatoria.

Introducción: Debido a su eficacia en el tratamiento de la obesidad mórbida, el bypass gástrico (BPG) sigue siendo una intervención realizada frecuentemente. Sin embargo, un grupo reducido de pacientes puede desarrollar complicaciones nutricionales y metabólicas que no logran controlarse con un tratamiento médico óptimo. En estos casos, puede ser necesario reestablecer la continuidad del tracto gastrointestinal por medio de la reversión del BPG (R-BPG).Objetivo: Presentar las indicaciones y resultados obtenidos en una serie de pacientes sometidos a una R-BPG.Materiales y método: Identificación y evaluación retrospectiva de todos los pacientes sometidos a una R-BPG en nuestra institución de manera consecutiva. Se registraron las características demográficas y antropométricas de la cirugía original y al momento de la reversión. Las complicaciones se registraron de acuerdo a la clasificación de Clavien-Dindo.Resultados: Se identificaron 7 pacientes en los cuales se realizó una R-BPG. En 2 casos la reversión fue por síndrome de intestino corto, en 3 casos por hipoglicemias severas refractarias a manejo médico y en 2 casos por diarrea crónica. La mediana de edad al momento de la reversión fue de 55 años. La mediana de tiempo desde la cirugía original hasta el momento de la reversión fue de 77 meses . La mediana de estadía hospitalaria fue de 6 días. No hubo complicaciones Clavien-Dindo ≥ III. La R-BPG logró revertir en todos los casos las complicaciones nutricionales y metabólicas.Conclusión: La restauración de la continuidad del tracto gastrointestinal permite el control de las complicaciones nutricionales y metabólicas.
PADANAN BONITA DENGAN KELAS KESESUAIAN LAHAN HUTAN TANAMAN JATI
Authors: Dwi R Heru 
Published: September 2021

Pendekatan bonita untuk menunjukan suatu kualitas suatu lahan dapat cepat diketahui pada hutan tanaman yang telah dikelola secara baik. Bila lahan tersebut belum dikelola atau baru saja dilakukan penanaman maka akan menjadi pembatas untuk mengetahui kelas kualitas lahannya. Sehingga diperlukan pendekatan lain selain bonita sebagai penilai kualitas lahan. Pendekatan tersebut adalah Kelas Kesesuaian Lahan (KKL), Pendekatan KKL merupakan pendekatan melalui pengukuran parameter-parameter lingkungan secara langsung. Untuk lebih mengintegrasikan dua pendekatan tersebut, maka perlu dipadu padankan antar dua pendekatan tersebut. Hasil padu padan antara bonita dengan KKL tersebut diharapkan evaluasi lahan hutan jati dapat dilakukan dalam keadaaan apapun, baik dalam keadaan lahan belum tertanami, lahan dengan tanaman muda yang belum dapat dievaluasi secara bonita. Meskipun KKL ini dapat dipergunakan untuk menilai/mengevaluasi kesuburan lahan hutan jati, ini bukan berarti akan menggantikan fungsi peran bonita dalam mengevaluasi lahan hutan jati. Aspek kepraktisan bonita dibanding dengan KKL dalam evaluasi lahan hutan jati, bonita sepertinya akan sulit tergantikan.
The executive function of bilingual and monolingual children: A technical efficiency approach
Authors: Papastergiou Athanasia , Pappas Vasileios , Sanoudaki Eirini 
Published: September 2021

AbstractThis paper introduces a novel approach to evaluate performance in the executive functioning skills of bilingual and monolingual children. This approach targets method- and analysis-specific issues in the field, which has reached an impasse (Antoniou et al., 2021). This study moves beyond the traditional approach towards bilingualism by using an array of executive functioning tasks and frontier methodologies, which allow us to jointly consider multiple tasks and metrics in a new measure; technical efficiency (TE). We use a data envelopment analysis technique to estimate TE for a sample of 32 Greek–English bilingual and 38 Greek monolingual children. In a second stage, we compare the TE of the groups using an ANCOVA, a bootstrap regression, and a k-means nearest-neighbour technique, while controlling for a range of background variables. Results show that bilinguals have superior TE compared to their monolingual counterparts, being around 6.5% more efficient. Robustness tests reveal that TE yields similar results to the more complex conventional MANCOVA analyses, while utilising information in a more efficient way. By using the TE approach on a relevant existing dataset, we further highlight TE’s advantages compared to conventional analyses; not only does TE use a single measure, instead of two principal components, but it also allows more group observations as it accounts for differences between the groups by construction.
Does C reactive protein/Albumin ratio have prognostic value in patients with COVID-19
Authors: Kalabin Aleksandr , Mani Vishnu R , Valdivieso Sebastian C , Donaldson Brian 
Published: September 2021

Introduction: There is paucity of data regarding C reactive protein/Albumin (CRP/Alb) ratio in patients with SARS-CoV-2 infection. We aimed to evaluate the significance of CRP/Alb ratio in COVID-19 patients.
Methodology: Patients hospitalized between March – April 2020 with COVID-19, who had CRP and Albumin levels documented within 24 hours from admission were retrospectively analyzed. Unpaired Student’s t-test was used for continuous and Pearson Chi-square (χ²) test for categorical variables. Univariate and multivariate logistic regression models were developed to assess the relationship between CRP/Alb and mortality. Nonparametric correlations were calculated using Spearman’s Rho correlation coefficient.
Results: 75 patients were included. Mean age was 62.92, 26 females (34.67%) and 49 males (65.33%), mean Body Mass Index (BMI) 29.86, mean body temperature 101.3 and mean length of stay (LOS) was 14.80 days. 24 (32%) patients required invasive mechanical ventilation and 51 (68%) did not, mean CRP/Alb ratio was 6.89 and 4.7 respectively (p = 0.036). 15 (20%) patients died, 60 (80%) survived and the mean CRP/Alb difference between these groups was also statistically significant (7.74 vs 4.83, p = 0.02). LOS (OR 0.71, 95% CI 0.57.-0.88, p < 0.001) and BUN (OR 1.04, 95% CI 1.01.-1.07, p = 0.006) were independent predictors of mortality by multivariate logistic regression, whereas CRP/Alb (OR 1.21, 95% CI 0.96.-1.51, p = 0.06) was not.
Conclusions: CRP/Alb ratio could be useful as a prognostic indicator of disease severity in COVID-19, but we could not corroborate its potential to predict mortality. The work was conducted at Columbia University College of Physicians and Surgeons at Harlem Hospital.
L'essor de la diagrammatologie
Authors: Stjernfelt Frederik , Chevalier Jean-Marie 
Published: September 2021

En 2007, le philosophe danois Frederik Stjernfelt a donné une nouvelle vigueur aux études sur les diagrammes en publiant son opus majeur Diagrammatology . Ce terme a acquis l’extension d’une sous-discipline à part entière à l’intérieur des études sémiotiques. La diagrammatologie fédère aujourd’hui des recherches venues des sciences cognitives aussi bien que du post-structuralisme, des mathématiques et des études littéraires. Frederik Stjernfelt explique comment la diagrammatologie résulte pour lui d’une redéfinition de certains concepts fondamentaux (ceux de signe, de proposition et de diagramme au premier chef) amorcée par le père du pragmatisme, Charles S. Peirce.
GenIDA : l’histoire naturelle et les comorbidités des troubles du neurodéveloppement d’origine génétique
Authors: Burger Pauline , Coutelle Romain , Strehle Axelle , Colin Florent , Collot Nicole , Koolen David , Kleefstra Tjitske , Mandel Jean-Louis 
Published: September 2021

Au sein des troubles du neurodéveloppement, la déficience intellectuelle (DI), avec ou sans Trouble du spectre de l’autisme (TSA) et/ou épilepsie touche 1 à 2 % des enfants et jeunes adultes, et il est estimé que plus de 50 % de ces cas ont une cause génétique unique. Plus de 1 000 gènes et anomalies chromosomiques récurrentes sont impliqués dans ces formes génétiques de DI ou TSA, correspondant à autant de maladies différentes, qui sont le plus souvent très insuffisamment décrites, du fait de leur rareté, de leur découverte en général récente, et du nombre souvent limité de patients. GenIDA est une base de données participative internationale initiée en 2016, dans le but de mieux caractériser les manifestations cliniques et les histoires naturelles de ces formes génétiques de DI et/ou TSA, afin d’en tirer des informations pouvant être utiles à la prise en charge des personnes atteintes. Pour cela, les parents de ces personnes sont sollicités pour répondre à un questionnaire structuré portant sur les paramètres physiques, médicaux, cognitifs et comportementaux. Les informations cliniques ainsi collectées sont analysées afin d’identifier de nouvelles informations ayant du sens pour les familles et les professionnels concernés par une maladie donnée. Disponible en 7 langues, le questionnaire a été rempli pour plus de 1 150 patients : les principales cohortes correspondent aux syndromes de Koolen-de Vries (KdVS), Kleefstra et KBG. L’analyse des données collectées a notamment permis d’identifier des problèmes respiratoires chez les patients KdVS non signalés auparavant, et des profils cognitifs dans ces 3 syndromes. GenIDA permet également d’envisager, de par ses propriétés et les résultats précédemment obtenus, la réalisation d’études longitudinales qui permettraient de suivre, en particulier, l’évolution des compétences en socialisation et la typologie des troubles du comportement.
Première consultation au Centre Psychiatrique d’Orientation et d’Accueil (CPOA) de l’hôpital Sainte-Anne à Paris. Récit d’une usagère
Authors: Ozenne Jessica 
Published: September 2021

Une usagère du CPOA à Sainte-Anne nous propose un témoignage simple et authentique de son expérience. Le CPOA est un service parisien qui accueille les urgences psychiatriques, et reçoit et oriente ceux qui ont besoin d’aide. A travers le regard d’une personne qui n’a jamais connu de service de psychiatrie et qui est confrontée à sa première consultation aux urgences, nous découvrons également le CPOA sous un autre jour, un autre regard. C’est du point de vue de l’usager néophyte, qui n’a pas de connaissance des rouages des secteurs de psychiatrie, que nous pouvons découvrir certaines particularités de cet accueil dans des urgences « qui ne ressemblent pas aux urgences générales ». Au décours de ce témoignage c’est la question de la connaissance de l’existence d’un tel service, pourtant indispensable à la population, qui se pose.

Authors: Tañá-Sanz Pedro , Rodríguez-Carrillo María Dolores , Elvira-Giner Belén , Ruiz-Santos María , Montés-Micó Robert , Tañá-Rivero Pedro 
Published: September 2021

PURPOSE:
To evaluate the refractive and visual outcomes following cataract surgery and implantation of a new enhanced monofocal extended depth of focus (EDOF) intraocular lens (IOL).

METHODS:
Fifty eyes of 25 consecutive patients who underwent implantation of the xact Mono-EDoF IOL (Santen Pharmaceutical Co, Ltd) were enrolled in this study. Main outcome measures were refractive error and monocular corrected (CDVA) and uncorrected (UDVA) distance visual acuity values. Monocular visual acuity at different vergences (defocus curve) was obtained. Patients were evaluated at 12 months postoperatively.

RESULTS:
At 1 year of follow-up, all eyes showed a postoperative spherical equivalent within ±1.00 diopters (D) and 95% of eyes within ±0.50 D. The mean postoperative spherical equivalent was −0.15 ± 0.28 D. A total of 88% and 100% of eyes showed UDVA and CDVA of 20/25 or better, respectively. The mean values of UDVA and CDVA (Snellen decimal) were 0.94 ± 0.09 (range: 0.70 to 1.00) and 0.99 ± 0.03 (range: 0.79 to 1.00), respectively. Defocus curve showed good visual acuity at distance and intermediate distances with a depth of focus value of 1.25 D. No visual disturbances were reported in the whole sample during the entire follow-up.

CONCLUSIONS:
The current study shows that this EDOF IOL provides good visual performance at far and intermediate distances. The lens may be considered for patients interested in reducing spectacle independence at intermediate distances.

Accelerated CXL Versus Accelerated Contact Lens–Assisted CXL for Progressive Keratoconus in Adults
Authors: Matlov Kormas Ran , Abu Tailakh Muhammad , Chorny Alexander , Jacob Soosan , Knyazer Boris 
Published: September 2021

PURPOSE:
To compare the clinical and tomographic properties of adult patients with keratoconus treated with accelerated corneal cross-linking (A-CXL) versus accelerated contact lens–assisted corneal cross-linking (A-CACXL).

METHODS:
Patients who underwent A-CXL and A-CACXL due to progressive keratoconus were enrolled from January 2015 to January 2018 in this retrospective case–control study. The treatment group (minimum corneal thickness of less than 400 µm after epithelium removal; 30 patients, 30 eyes) was treated with A-CACXL; the control group (minimum corneal thickness of 400 µm or greater, 32 patients, 32 eyes) was treated with A-CXL. Assessments occurred before treatment and 12 months postoperatively. Demographic, clinical, and tomographic data were obtained from outpatient clinic reports.

RESULTS:

Significant improvement in visual acuity was evident at 12-month follow-up for the control group in uncorrected distance visual acuity (0.62 ± 0.42 vs 0.43 ± 0.31 logMAR,
P
= .01) and the treatment group in corrected distance visual acuity (0.51 ± 0.30 vs 0.40 ± 0.49 logMAR,
P
= .03). Progression of keratoconus was halted at similar rates for both groups (76.7% treatment, 84.4% control,
P
= .21). Mean minimum corneal thickness showed minor but significant thinning at the 12-month follow-up visit compared to baseline (control group = 463 ± 31 vs 450 ± 35 µm,
P
> .01; treatment group = 398 ± 32 vs 388 ± 41 µm,
P
= .02).

CONCLUSIONS:
A-CACXL halted keratoconus progression in 76.7% of eyes and achieved regression in 33.3% of eyes, with rates comparable to A-CXL. Visual outcomes improved for both groups, with similar keratometry changes. A-CACXL is an effective and safe option for patients with keratoconus and thin corneas, with results similar to A-CXL treatment in patients with a minimum corneal thickness of 400 µm or greater.

Pain Control Following Photorefractive Keratectomy: A Prospective Clinical Trial Comparing Codeine Versus Oxycodone for the Management of Postoperative Pain
Authors: Palochak Cherilyn Mae A. , Reed Donovan S. , Apsey Douglas A. , Legault Gary L. , Carlton Darrel , Caldwell Matthew C. , Townley James R. , Madsen Michael H. , Evangelista Charisma B. 
Published: September 2021

PURPOSE:
To compare the efficacy of oral codeine plus acetaminophen versus oxycodone plus acetaminophen for severe pain control following photorefractive keratectomy (PRK).

METHODS:
This single-center trial randomized 200 patients to receive codeine 30 mg/acetaminophen 325 mg (codeine group) or oxycodone 5 mg/acetaminophen 325 mg (oxycodone group)every 4 hours as needed for severe pain for 4 days following PRK. Patients recorded postoperative pain, tablet consumption, and tetracaine use. Patients were monitored at postoperative 1 day, 1 week, and 1, 3, and 6 months for visual acuity and follow-up. Study outcomes were mean postoperative pain, treatment and tetracaine use, and visual acuity.

RESULTS:

Analysis of 197 patients who completed the trial (97 codeine group and 100 oxycodone group) showed mean pain scores were lower in the codeine group throughout the intervention period. Mean pain scores were higher in the oxycodone group than the codeine group on postoperative days 2 and 4 (
P
= .017 and
P
= .034, respectively). The oxycodone group consumed more tablets than the codeine group, with a difference on postoperative day 2 (
P
= .019), and used a greater number of tetracaine drops (
P
= .015). Repeated measures analysis of variance showed significant improvement in visual acuity in both groups with no difference in visual outcomes (
P
= .81).

CONCLUSIONS:
Codeine/acetaminophen is as effective and safe as oxycodone/acetaminophen for pain control following PRK, with no clinical difference in overall pain control and long-term visual outcomes. This implies that treating postoperative pain after PRK with a Schedule III opioid (codeine) is effective and potentially decreases the risk of misuse by a higher regulated Schedule II opioid (oxycodone), lowering the potential for abuse and dependence.

Comparison of Axis Determination With Different Toric Intraocular Lens Power Calculation Methods
Authors: Röggla Veronika , Schartmüller Daniel , Schwarzenbacher Luca , Chbib Rima Al , Leydolt Christina , Menapace Rupert 
Published: September 2021

PURPOSE:
To compare the axis position of the measured total corneal astigmatism (TCA) with the axis of the anterior keratometry and the calculated axis position of different toric intraocular lens (IOL) calculators.

METHODS:
A total of 163 astigmatic eyes of 163 patients were retrospectively analyzed. The axis of the actual TCA, measured with anterior segment optical coherence tomography, was compared to the anterior keratometric value (Group I) and three different methods of TCA calculation for toric IOL power determination: Abulafia-Koch regression formula (Group II), Barrett Toric Calculator V2.0 (Group III), and Barrett Toric Calculator V2.0 including measured posterior keratometric value (Group IV). Eyes were assigned to three subgroups: with-the-rule, against-the-rule, and oblique astigmatism.

RESULTS:
The mean deviation calculated from measured TCA was +0.56° (Group I), −0.32° (Group II), −0.37° (Group III), and −1.00° (Group IV). For with-the-rule astigmatism, the TCA axis agreed most with Group I (6.5% outliers > 5° deviation). For against-the-rule astigmatism, Group IV and Group II were closest to the measured TCA axis (1.5% and 3% outliers with > 5° deviation).

CONCLUSIONS:
The means of the calculated axis were similar to the measured TCA, but the proportion of outliers with an axis deviation of greater than 5° showed remarkable differences. Isolated anterior keratometric value measurements showed the fewest outliers in with-the-rule astigmatism. In against-the-rule astigmatism, Abulafia-Koch calculation should be used for axis determination.

Authors: Sayin Osman , Altinkaynak Hasan , Adam Mehmet , Dirican Emrah , Agca Okan 
Published: September 2021

BACKGROUND AND OBJECTIVE:
To investigate the reliability and quality of vitreoretinal surgery videos posted on YouTube.

PATIENTS AND METHODS:
A search was made using the keywords “vitrectomy,” “retinal surgery,” and “vitreoretinal surgery” on YouTube. Total view counts, numbers of comments, likes and dislikes, publishing dates, and source of videos were recorded. Educational quality and accuracy of the video content were evaluated using the DISCERN score, Journal of the American Medical Association (JAMA) scoring system, and Global Quality Scores (GQS).

RESULTS:
There were 208 videos included in the study; 152 (73.1%) videos were uploaded by doctors and 56 (26.9%) videos uploaded by non-doctors. Mean DISCERN, JAMA, and GQS scores were 37.65 ± 10.49 (20–69), 0.82 ± 0.52 (0–4), 2.86 ± 0.86 (1–5), respectively.

CONCLUSIONS:
Vitreoretinal surgery videos on YouTube were of low quality and reliability. Those who want to use YouTube videos as a reference for vitreoretinal surgery should pay extra attention to selection of content.

Invertibility Threshold for Nevanlinna Quotient Algebras
Authors: Nicolau Artur , Thomas Pascal J. 
Published: September 2021

AbstractLet
$\mathcal {N}$
be the Nevanlinna class, and let B be a Blaschke product. It is shown that the natural invertibility criterion in the quotient algebra
$\mathcal {N} / B \mathcal {N}$
, that is,
$|f| \ge e^{-H} $
on the set
$B^{-1}\{0\}$
for some positive harmonic function H, holds if and only if the function
$- \log |B|$
has a harmonic majorant on the set
$\{z\in \mathbb {D}:\rho (z,\Lambda )\geq e^{-H(z)}\}$
, at least for large enough functions H. We also study the corresponding class of positive harmonic functions H on the unit disc such that the latter condition holds. We also discuss the analogous invertibility problem in quotients of the Smirnov class.
