Authors: Dwivedi Namrata , Jain Shalini , Kumar Ashok 
Published: March 2022

Aims:
This study aims to study and compare the outcome of tympanic membrane grafting medial or lateral to handle of malleus in terms of graft uptake and closure of air bone gap.

Materials and Methods:
This prospective randomized study included 60 patients who presented in the ENT Outpatient Department of ABVIMS and Dr. Ram Manohar Lohia hospital with Inactive chronic Otitis media (COM) (tubo tympanic disease). Patients were randomly allocated to two groups of 30 patients each. Group A contained patients with graft placed medial to handle of malleus and Group B contained patients with graft placed lateral to handle of malleus. Patients were followed up at the 4th, 6th, and 12th week postoperatively for graft uptake and hearing gain were assessed.

Results:
There was significant mean hearing gain postoperatively compared to preoperative in pure tone audiometry, however, there is no significant difference in short-term outcomes of both the grafting techniques for graft uptake and audio metric results.

Conclusion:
Both medial and lateral placement of grafting material to malleus handle into type I underlay tympanoplasty are good methods for graft uptake and audiological outcome for inactive COM (Tubo tympanic disease).

Authors: Jibril Yasir Nuhu , Shamsu Khadija Ahmad , Adamu Auwal , Abdullahi Hamisu , Kolo Emmanuel Sara , Ahmed Sagir Gumel 
Published: March 2022

Background:
Sickle cell disease is characterized by vaso-occlusion which leads to impaired blood supply to several organs. The cochlear in particular has been known to be highly sensitive to anoxia which is, in turn, a proven cause of sensorineural hearing loss (SNHL). Early detection of hearing loss is paramount in these patients, as the cochlear ischemic damage is repetitive and progressive. Once the damage is sufficiently enough to cause noticeable hearing loss, the loss is mostly substantial and irreversible. Otoacoustic emission is useful in detecting early cochlear damage.

Materials and Methods:
Children with sickle cell anemia (SCA) (HbSS) aged between 1 and 12 years diagnosed by hemoglobin electrophoresis and equal number of controls matched (HbAA) matched for age and sex were recruited for the study. All participants underwent a detailed ear, nose, and throat examination and tympanometry. Those with normal middle ear function were further subjected to transient-evoked otoacoustic emissions (TEOAEs) testing.

Results:
There were 60 patients with SCA (cases) and 60 controls. The age of the participants ranged between 1–12 years with a mean of 6.5 ± 3.74 among the cases and 7.02 ± 3.54 among the controls. The male–female ratio was 0.9:1. Among participants with normal middle ear function, TEOAE was abnormal in 43 (48.8%) ears of the cases and 70 (73.7%) ears of the controls. There was a statistically significant difference in abnormal TEOAEs outcome between cases and the control group (P = 0.002).

Conclusion:
Children with SCA had a high rate of abnormal cochlear function. Therefore, there is a need for periodic monitoring of cochlear function in these patients so as to detect and treat SNHL early.

Authors: Sheikh Mohammed , Zain Adnan , Marai Majdi 
Published: March 2022

The electrocardiogram (ECG) signals provide information on the heart rate where it provides evidence to support the diagnoses of cardiac diseases and arrhythmias. Currently ,T-wave has been used to forecast Sudden Cardiac Death (SCD). T-wave recognition is an excellent indicator in the analysis and interpretation of cardiac arrhythmia. Based on this aspect, it is necessary to develop an accurate technique for the detection of these waves. The main aim of this current study is to develop a new threshold-free method for the detection of T wave peak in an (ECG), which was characterized by a threshold free detection of T peak with a special moving window for T wave (and can be used for P wave) between each two RR peaks. A Band pass filter and a notch filter are used to enhance the detection of these required peaks. This algorithm is implemented using MATLAB tools. The database used in this work is downloaded from MIT-BIH Arrhythmia(Lead II). The method is validated using 40 recorded data. The obtained average sensitivity and average positive predictivity of the detection method are 98.4% and 99.0% respectively.

Authors: Aldambi Abdulla Ali , Al-Khudafi Abbas Mohamed 
Published: March 2022

The accuracy of many petroleum engineering calculations (e.g., material balance calculations, reserve estimation, well test analysis, advanced production data analysis, nodal analysis, surface network modeling, surface separation, and numerical reservoir simulations) largely depends on the accuracy of the data on pressure, volume, and temperature (PVT). An approach to improve the material balance calculation method is presented in this study. To achieve the objective, PVTP and MBAL Software programs were applied. PVT model was built by different methods. Software was implemented to calculate stock-tank oil, initially in place (STOIIP), using different approaches. Sensitive analysis was performed to investigate the effect of different parameters on material balance calculation. Illustration of the proposed approach was done on the data obtained from AL-Nasr oil field. The Average absolute error of PVT properties such as bubble-point pressure, relative volume, oil formation volume factor, Solution gas oil ratio and oil density is used to compare between actual and calculated values. Results showed a good agreement. History production (cumulative oil production, cumulative gas production, cumulative water production) were also calculated to investigate the match between history parameters and calculated parameters. Results indicated that the impact of PVT errors on material balance calculations can be significant.

Authors: Ebrahim Balqis AL-Sayeed Abdulla 
Published: March 2022

Malaria and dengue are the most prevalent vector-borne diseases worldwide and represent major public health problems; both are endemic in similar tropical regions and, therefore, may result in the possibility of co-infection. Aim: To determine the occurrence of concurrent malaria and dengue infection Methods: we carried out retrospective cohort study for a total of 218 febrile patients attending Al-Sadaqa Teaching Hospital Out Patient Department over a period from August to November 2019. Blood samples were collected for malaria and dengue investigations and were tested for thin and thick film for malaria and NS-1 antigen and IgM ELISA for dengue fever. Result: Out of 218 patients, the total prevalence in malaria, dengue and co-infection patients were 50%, 62.4%, and 40.3% respectively. In term of age, the highest percentage was recorded among patients with malaria of the age over 58 was 78.3%, in dengue fever patients of the age 38-47 was 72.5 % with p value 0.05 and in co-infection among of the age 18-27 was 49.3% with p value 0.001. In term of sex the prevalence was 66.9%, 43.5% and 39.1 % in malaria, co-infection and dengue fever respectively. Conclusion: High prevalence of co-infection was observed among febrile infection compared to the isolated infection. Simultaneous infection among febrile patients is a true burden and there is a need for further study for patients in endemic areas.

Published: March 2022

Laparoscopic cholecystectomy become the treatment of choice for symptomatic gallstone disease. Difficult procedure may confront the surgeon, but these situations are often predictable based on a number of clinical and paraclinical factors. This study aimed to determine which clinical and paraclinical factors are associated with difficult laparoscopic cholecystectomy. Total of 405 patients with symptomatic gallstone disease, who underwent laparoscopic cholecystectomy between 1st Marc 2018 and 29th February 2020,in 22 May Hospital, Aden, were included in the study. Patient with gallbladder cancer or acalcular cholecystitis were excluded from the study. Relevant data which include clinical and paraclinical findings as well as operative findings were collected to a specially designed questionnaire form. Data analysis was done by SPSS version 17 software. Univariate analysis for categorical variables was done using Chi square or Fischer's exact test. Continuous data were tested for normal distribution and analyzed using Mann Whitney test. P- value <0.05 was considered statistically significant. Female preponderance (88.1%) was observed. Mean age was 42.6 ± 13.7. Difficult laparoscopic cholecystectomy found in 137 patients (33.8%). A statistically significant association were found between difficult laparoscopic cholecystectomy and gender (p-value <0.001), history of obstructive jaundice (p-value<0.001), previous endoscopic retrograde cholangio-pancreaticography (p-value <0.001), previous abdominal surgery (p-value =0.005), white blood cell count (p-value= 0.001), gallbladder wall thickness ≥ 4mm (p-value <0.001) , impacted stone in cystic duct (p-value <0.001), pericholecystic fluid collection (p-value <0.001), dilated common bile duct more than 7 mm (p-value =0.001), contracted gallbladder despite adequate fasting (p-value <0.001). Number of preoperative factors were identified, which have statistically significant association with difficult laparoscopic cholecystectomy. Knowledge of these factors by the surgeon before operation is imperative to make the necessary precautions before operation.

Novel assessment of numerical forecasting model relative humidity with satellite probabilistic estimates
Authors: Radice Chloé , Brogniez Hélène , Kirstetter Pierre-Emmanuel , Chambon Philippe 
Published: March 2022

Abstract. A novel method of comparison between an atmospheric model and satellite
probabilistic estimates of relative humidity (RH) in the tropical atmosphere
is presented. The method is developed to assess the Météo-France
numerical weather forecasting model ARPEGE (Action de Recherche Petite Echelle Grande Echelle) using probability density
functions (PDFs) of RH estimated from the SAPHIR (Sondeur Atmosphérique du
Profil d'Humidité Intertropicale par Radiométrie) microwave sounder. The
satellite RH reference is derived by aggregating footprint-scale
probabilistic RH to match the spatial and temporal resolution of ARPEGE over
the April–May–June 2018 period. The probabilistic comparison is discussed
with respect to a classical deterministic comparison confronting each model
RH value to the reference average and using a set confidence interval. This
study first documents the significant spatial and temporal variability in
the reference distribution spread and shape. We demonstrate the need for a
finer assessment at the individual case level to characterize specific
situations beyond the classical bulk comparison using determinist “best”
reference estimates. The probabilistic comparison allows for a more
contrasted assessment than the deterministic one. Specifically, it reveals
cases where the ARPEGE-simulated values falling within the deterministic
confidence range actually correspond to extreme departures in the reference
distribution, highlighting the shortcomings of the too-common Gaussian
assumption of the reference, on which most current deterministic comparison
methods are based.
A case study of a ducted gravity wave event over northern Germany using simultaneous airglow imaging and wind-field observations

Published: March 2022

Abstract. An intriguing and rare gravity wave event was recorded on the night of 25 April 2017 using a multiwavelength all-sky airglow imager over northern
Germany. The airglow imaging observations at multiple altitudes in the
mesosphere and lower thermosphere region reveal that a prominent upward-propagating wave structure appeared in O(1S) and O2 airglow
images. However, the same wave structure was observed to be very faint in OH airglow images, despite OH being usually one of the brightest airglow
emissions. In order to investigate this rare phenomenon, the altitude
profile of the vertical wavenumber was derived based on colocated meteor
radar wind-field and SABER temperature profiles close to the event location.
The results indicate the presence of a thermal duct layer in the altitude
range of 85–91 km in the southwest region of Kühlungsborn, Germany.
Utilizing these instrumental data sets, we present evidence to show how a
leaky duct layer partially inhibited the wave progression in the OH airglow
emission layer. The coincidental appearance of this duct layer is responsible for the observed faint wave front in the OH airglow images compared O(1S) and O2 airglow images during the course of the night over northern Germany.
Economía y Pandemia por COVID-19: Efectos sobre la subjetividad social. El caso de Chile
Authors: Madariaga Araya Carlos 
Published: March 2022

Se analiza la relación existente entre economía y pandemia por Covid-19, a partir del debate que cursa a nivel internacional respecto de la crisis civilizatoria que ha develado el fenómeno pandémico. Se revisan las opiniones de teóricos sociales sobre las características de esta crisis y los caminos probables de salida de la misma. Luego se caracteriza la pandemia como un hecho social total y se describen los fundamentos epistemológicos de este concepto y su relación con la multideterminación del pathos viral. Posteriormente se debate alrededor de las formas de subjetividad que son propias del capitalismo tardío y las nuevas producciones de sujeto derivadas de la influencia del fenómeno pandémico, especialmente sobre el proceso salud/enfermedad/atención. Finalmente, se describen las características específicas del desarrollo económico chileno en su fase neoliberal, su influencia en el diseño de las políticas públicas con las que se ha abordado la pandemia y la participación de ambos en la producción de subjetividad. Se concluye que la pandemia por Covid-19 es un componente estructural del capitalismo en su versión necroneoliberal y genera formas diferenciadas de afectación biopsicosocial, cultural, económica, social, política y medioambiental en correspondencia con las inequidades de clase, género, étnicas, generacionales, territoriales y ecológicas. Así ha sido en Chile, país donde las políticas sanitarias contra el virus operan con un enfoque economicista y no salubrista.
Una aproximación al problema del suicidio en el Paraguay
Authors: Estigarribia Ángel 
Published: March 2022

El suicidio como causa de muerte supera a muchas enfermedades muy extendidas en el mundo también constituye la causa más frecuente de muerte violenta no accidental. A escala planetaria causa más muertes que el terrorismo y las guerras. En las últimas dos décadas en el Paraguay, el incremento en el número de suicidios ha sido notable y bastante preocupante si se toma en cuenta que no existe un servicio público de auxilio para situaciones de riesgo de suicidio y el presupuesto de salud mental del país es el más bajo del Cono Sur. Al mismo tiempo que la crisis económica, el desempleo y la precariedad laboral, afectan sobre todo a la franja etaria juvenil, allí también es donde se ubica la cantidad más alta de suicidios de los últimos años, el análisis de este trabajo comporta sobre todo el año 2020. No hay peor problema que desconocer el problema. El número de suicidios en Paraguay es más alto que los homicidios y feminicidios, en 12 años hubo un incremento del 218%. Urge investigar causas y detonantes y pensar en respuestas políticas de urgencia y también estructurales.

The prognostic and clinicopathological significance of desmoglein 2 in human cancers: a systematic review and meta-analysis
Authors: Wang Jiantao , Hao Siyuan , Gu Junjie , Rudd Sean G. , Wang Yan 
Published: March 2022

Objective
The survival and clinicopathological significance of desmoglein 2 (DSG2) in various cancers is controversial. Thus, we performed this systematic review and meta-analysis to explore the preliminary prognostic value of DSG2.

Methods
Eligible studies were identified from databases including PubMed, the Cochrane Library, Embase, Web of Science and Scopus. Hand searches were also conducted in relevant bibliographies. We then extracted and pooled hazard ratio (HR) of overall survival (OS) and odds ratio (OR) of clinicopathological features.

Results
A total of 11 eligible studies containing 1,488 patients were included. Our results demonstrated that in non-small cell lung cancer (NSCLC), high DSG2 expression is associated with poor OS. However, in digestive system cancer and female reproductive system cancer, there were no statistically significant associations between OS and DSG2.

Conclusions
Based on the findings of this study, high DSG2 expression is associated with worse prognosis in patients with NSCLC, and thus DSG2 expression could be a biomarker for prognosis in NSCLC.
Evaluation of change in trabecular bone structure surrounding dental implants by fractal dimension analysis and comparison with radiomorphometric indicators: a retrospective study
Authors: Karadag Ilkim , Yilmaz Hasan Guney 
Published: March 2022

Background
The trabecular bone surrounding dental implant show some structural changes during healing period. The purpose of this study is to observe the change in trabecular bone with fractal dimensional analysis from baseline to 3rd month of implant placement. It was also aimed to determine the correlation of fractal dimension (FD) change with morphometric indices, mandibular cortical index (MCI) and mandibular cortical width (MCW).

Methods
Digital panoramic radiographs taken from 14 patients were evaluated in this study. A total of 30 implants which were placed on mandibular premolar or molar region were included. MCI and MCW assessments were made on baseline radiograph and FD were analyzed on baseline and 3rd month radiograph. FD change by time was recorded separately for every ROI. A paired sample t-test was used to evaluate the change between FD-baseline and FD-3rdmonth values. One-way ANOVA was used to determine the relationship between FD change and MCI. FD change and MCW measurements correlation was calculated by Pearson correlation analysis

Results
FD value increased in 75 of 90 implant-adjacent regions evaluated in the 3rd month and it was observed that the FD values were statistically significantly increased in the mesial, distal and apical regions at the 3rd month measurements. There was no statistically significant relationship between mean FD change and MCI, and there was no correlation between mean FD change and MCW value.

Discussion
There are many studies evaluating the resorptive changes in bone. However, there are few studies investigating whether there is a correlation between pre- and post-operative trabecular pattern with MCI and MCW. The results of this study indicate that the implants have an improving effect on bone trabeculation in the region where they are placed.
