Published: September 2022

Introduction: Human Immunodeficiency Virus causes an immense amount of problems throughout the world, especially in sub-Saharan countries. Recently viral load is thought to be a good indicator in assessing HIV progression. Complementary feeding practice and type of complementary food are the major factors that affect VL Status. However, in Ethiopia there is paucity of evidence on the factors that could affect viral load among HIV exposed infants. Therefore, this study aimed to identify factors that affect VL Status among HIV positive children on ART at Zewditu Memorial Hospital (ZMH), Addis Ababa, Ethiopia using a case control study design. Methods: Institution based unmatched case- control study was employed among a total of 241 (71 cases and 170 controls) children attending for follow up in ZMH ART clinic from July to August 2020. The interviewer conducts a face-to-face interview for 24 hour’s dietary diversity from mothers using standardized and pre tested questioner. SPSS 20 was used for data entry and cleaning, while Stata 14 was used for data analysis. Backward stepwise logistic regression analysis was used to determine the association of the factors with the outcome variable. A P-value ≤ 0. 05 was considered statistically significant at 95% confidence level throughout the study. Result: Out of 241 children, 71 of them had high VL status, while the rest 170 of them had low VL status. Poor dietary diversity increases the risk of high VL on ART children [AOR= 4. 37, 95% CI: 2. 12-10. 71]. The risk of high VL increase on children whose mother’s marital status was single [AOR=4, 95% CI: 1. 40, 9. 70], among children who have a daily laborer mothers [AOR= 10. 6, 95% CI: 3. 20, 21. 67], and working on nongovernmental organizations [AOR=5. 32, 95% CI: 1. 68, 10. 51]. Children on WHO clinical stage 3 and 4 [AOR =15. 22, 95% CI: 4. 1, 39. 41], those children who started complementary feeding lately (after 6 months) [AOR= 4. 69, 95% CI: 2. 35, 13. 6] and children with poor Infant dietary diversity score [ AOR= 4. 37, 95% CI: 2. 12-10. 71]. Conclusion: Maternal marital status, maternal occupation, WHO clinical stage, late initiation of complementary feeding practice, and infant dietary diversity score are the factors affecting VL status in HIV positive children on ART at Zewditu memorial hospital.

Life skill erat kaitannya dengan kecakapan atau kemampuan yang diperlukan sesorang agar menjadi independen dalam kehidupan. Pendidikan life skills mengorientasikan siswa untuk memiliki kemampuan dan modal dasar agar dapat hidup mandiri dan survive di lingkungannya. Pendidikan life skills diperlukan dan mendesak untuk diterapkan di Indonesia karena muatan kurikulum di Indonesia cenderung memperkuat kemampuan teoritis-akademik (academic skills). Pembelajaran life skills merupakan salah satu alternatif sebagai upaya mempersiapkan peserta didik agar memiliki sikap dan kecakapan hidup sebagai bekal bagi kehidupannya kelak melalui sebuah kegiatan pembelajaran yang aktif, kreatis dan menyenangkan.

Kegiatan ekstra kurikuler dalam pendidikan dimaksudkan sebagai jawaban atas tuntutan dari kebutuhan anak didik, membantu mereka yang kurang, memperkaya lingkungan belajar dan memberikan stimulasi kepada mereka agar lebih kreatif. Suatu kenyataan bahwa banyak kegiatan pendidikan yang tidak selalu dapat dilakukan dalam jam-jam sekolah yang terbatas itu, sehingga terbentuklah perkumpulan anak-anak diluar jam sekolah yang dianggap dapat menampung dan memenuhi kebutuhan serta minat mereka.

kecakapan hidup (life skills) dapat difahami sebagai usaha untuk membantu dan membimbing aktualisasi potensi peserta didik untuk mencapai sejumlah kopetensi, baik berupa pengetahuan, keterampilan sikap dan nilai, yang mengarah pada kemampuan memecahkan permasalahan hidup, menjalani kehidupan secara mandiri dan bermartabat, serta proaktif dalam mengatasi masalah

Epidemiological and economic burden of pneumococcal diseases in Canadian
children

Authors: Petit G , De Wals P , Law B , Tam T , Erickson LJ , Guay M , Framarin A
Published: September 2022

Background: With the arrival of a new conjugate pneumococcal vaccine, it is
important to estimate the burden of pneumococcal diseases in Canadian children. The
epidemiological data and the economic cost of these diseases are crucial elements in
evaluating the relevance of a vaccination program.
Methods: Using provincial
databases, ad hoc surveys and published data, agespecific incidence rates of
pneumococcal infections were estimated in a cohort of 340,000 children between six
months and nine years of age. The costs of these diseases to the health system and to
families were also evaluated using data from Quebec and Manitoba.
Results:
Cumulative risks were one in 5000 for pneumococcal meningitis, one in 500 for bacteremia
and one in 20 for pneumonia, leading to 16 deaths in the cohort. About 262,000 otitis
media episodes and 32,000 cases of myringotomy with ventilation tube insertion were
attributable to Streptococcus pneumoniae. Societal costs were estimated at $125 million,
of which 32% was borne by the health system and 68% was borne by families. Invasive
infections represented only 2% of total costs, while 84% were generated by otitis
media.
Conclusion: Pneumococcal infections represent a significant burden for
Canadian children and society that could be significantly reduced through
immunization.

SYNOPSIS: This valuable resource on digital signal processing (DSP) principles and
approaches is designed to inform and guide anyone interested in hearing sciences. The
text focuses on the complexities of signal processing algorithms used in modern digital
hearing aids and therein presumes the reader has a basic understanding of hearing aid
fitting algorithms and their mathematical concepts and representations. Common features
found in modern hearing aids such as feedback cancellation, wind protection screens,
dynamic range compression, multiple and single microphones arc described with clarity in
the text and additionally illustrated with mathematical representations.
The
textbook contains 13 chapters that range from the basics of analog to digital Hearing
Aid Technologies, in Chapter 1 through the specific algorithms required to balance
Bilateral Signal Processing in the final Chapter 13. In between these chapters, the
reader is confronted with the myriad of insights and challenges to the hearing aid user
including “the Cocktail Party” and other effects that compromise desired signal to noise
ratios. Chapter 2 introduces Signal Processing Basics; Chapters 3 - 7 deal with the DSP
hardware and algorithms; 3) the Electro-acoustic System; 4) Directional Microphones; 5)
Adaptive and Multi-microphone Arrays; 6) Wind Noise-, and 7) Feedback Cancdlation.Thc
remaining chapters cover signal processing related to physiological and perception
dynamics: 8) Single Microphone Noise Suppression; 9) Spectral Subtraction; 10) Spectral
Modifications; II) Sound Modifications (to improve speech intelligibility); and 12)
Sound Classification to help determine parameters for algorithms in challenging
listening environments.
Otological Findings Among Nigerian Children with Sickle Cell
Anaemia

Authors: Alabi S , Ernest K , Eletta P , Owolabi A , Afolabi A , Suleiman O
Published: September 2022

Background/aim: Various degrees of hearing loss have been associated with sickle
cell anaemia, especially of the sensorineural type (SNHL). However, there is little
information on hearing pattern among sickle cell children in Nigeria. This study is to
determine the prevalence of sensorineural hearing loss (SNHL) among children with sickle
cell anaemia (SCA).
Patients and methods: Eighty (80) stable children aged 4-15
with Hbss attending the pediatric sickle cell clinic and also 60 control patients with
HbAA, matched for age. sex at the pediatric general medical clinic of the University of
llorin teaching hospital. llorin, Nigeria, all had prospective study of their pure tone
audiological assessment (PTA) and tvmpanometric evaluations done over a year
period.
Results: Their age range was 4-15 years with a mean of 9.4 for the 1 ibss
and 9.7 for the control group. The male/fcmale ratio was 1.3:1 and 15:1 for SCA and
control subjects respectively. 25 subjects (50 ears) had abnormal audiograms among the
SCA subjects and OME was the cause in 22 subjects and only three (3) had mild SNHL which
was bilateral. However, in the control group 15 had abnormal audiograms and all were due
to OME and none had SNHL OME was bilateral in 19 subjects with SCA. two on the left and
only one on the right In the control group. 11 of the OMK was bilateral and only four
were on the left side. The prevalence of SNHL was 3.8% and OME was 27.5%.

Conclusion: We have found a prevalence rate for SNHL of 3.8% for 80 subjects with HbSS,
and all cases have been a mild bilateral high frequency SNHL. Our findings suggested
that SNHL is uncommon in early childhood, specifically during the years of language
acquisition and early schooling. This could mean an age dependant prevalence rate of
SNHL among SCA patients. However, no difference in the incidence of OMK among both
groups which can lead to educational difficulties from the resultant speech and language
defects.

A systematic review of the interventions to promote the wearing of hearing
protection

Authors: El Dib RP , Atallah AN , Andriolo RB , Soares BG , Verbeek J
Published: September 2022

Context and Objective: Noise-induced hearing loss can only be prevented by
eliminating or lowering noise exposure levels. When the source of the noise cannot be
eliminated, workers have to rely on hearing protection equipment. The aim here was to
summarize the evidence for the effectiveness of interventions to enhance the wearing of
hearing protection among workers exposed to noise in the workplace.
Data Source:
Studies with random assignment were identified by an electronic search of the medical
literature up to 2005. Data were double-entered into the Review Manager software,
version 4.2.5.
Data Synthesis: Two studies were found. A computer-based
intervention tailored to individual workers risks and lasting 30 minutes was not found
to be more effective than a video providing general information for workers. A second
randomized controlled trial evaluated the effect of a four-year school-based hearing
loss prevention program among schoolchildren working on their parents farms. The
intervention group was twice as likely to wear some kind of hearing protection as was
the control group (which received only minimal intervention).
Reviewers’
Conclusions: The limited evidence does not show whether tailored interventions are more
or less effective than general interventions among workers, 80% of whom already use
hearing protection. Long-lasting school-based interventions may increase the use of
hearing protection substantially. Better interventions to enhance the use of hearing
protection need to be developed and evaluated in order to increase the prevention of
noise-induced hearing loss among workers.

Published: September 2022

Background: It was the aim of this study to analyze the clinical manifestations,
the incidence of each variant and the co-morbid conditions of benign paroxysmal
positional vertigo (BPPV) as well as the response to treatment.
Methods: One
hundred and fifty-seven patients with BPPV were reviewed prospectively. An extensive
neurotologic examination was performed. All patients were treated with an appropriate
canalith repositioning maneuver (CRM).
Results: In 138 patients, the posterior
canal (PC) was involved, in 14 patients, the horizontal canal (HC), in 2 patients, the
anterior canal (AC), and in 3 patients, both the PC and HC. A history of head trauma was
identified in 17 patients. In 1 patient, sensorineural hearing loss on the affected side
and, in another, bilateral peripheral vestibular loss was present. A history of migraine
was reported in 21 cases. A resolution attributable to the first CRM was achieved in 132
patients.
Conclusions: PC involvement was the most frequent type, constituting
87.9% of all BPPV cases. HC, AC and mixed canal types were relatively rare constituting
8.9, 1.3 and 1.9% of the cases, respectively. Response to the first CRM was recorded in
84.1%. Association with migraine was recorded in 13.4% of the patients.

Effect of climate on the bacteriology of chronic suppurative otitis
media

Authors: Yildirim A , Erdem H , Kilic S , Yetiser S , Pahsa A
Published: September 2022

Objectives: We evaluated the correlation between the microbial content of chronic
suppurative otitis media (CSOM) and regional climatic parameters.
Methods: We
assessed the interrelations between monthly mean records of temperature, maximum
temperature, atmospheric pressure, and humidity and the aerobic microbial flora in
CSOM.
Results: Forty-three bacteria of Enterobacteriaccae, 67 Staphylococcal spp,
51 Pseudomonas aeruginosa, 9 Streptococcus pneumoniae, 1 alpha-hemolytic Streptococcus,
1 Enterococcus sp, and 2 Edwardsiella tarda strains were recovered from 173 patients
with CSOM. There was a good relationship between enteric bacteria and monthly mean
temperature (r = 0.501) and significant colonization rates due to increasing monthly
mean temperature (p = .040) and monthly mean maximum temperature values (p = .048).

Conclusions: When the weather warmed, the frequency of isolation of enteric bacteria
increased significantly. Temperature changes may affect the enteric bacterial
colonization of CSOM.

Bacteriological profile in chronic suppurative otitis media in Eastern
Nepal

Authors: Sharma S , Rehan HS , Goyal A , Jha AK , Upadhyaya S , Mishra SC
Published: September 2022

Aural swabs were collected from 250 patients with chronic suppurative otitis media
(CSOM) (tubotympanic disease). Duration of car discharge was more than 6 months for
culture and sensitivity test. The disease was unilateral in 178 (71.2%) and bilateral in
72 (28.8%) patients. From a total of 322 aural swab cultures, 324 organisms were
isolated with predominance of Pseudomonas aeruginosa (36.4%) followed by Staphylococcus
aureus (30.2%). All the isolated Gram-negative organisms showed in vitro sensitivity to
ciprofloxacin, amikacin, ofloxacin, and gentamycin, whereas cloxacillin, ofloxacin,
erythromycin, ciprofloxacin, gentamicin and tetracycline were more effective against
Grampositive isolates. Most isolates were resistant to amoxycillin. It is concluded that
ciprofloxacin is preferred to aminoglycosides as an important tool in the treatment of
CSOM because of its lower cost, lack of ototoxicity and availability as topical oral
preparations.

Management of an ‘Ear Camp’ for children in Namibia

Authors: Lehnerdt G , Van Delden A , Lautermann J
Published: September 2022

Objective: In this publication, we present our experiences with managing an ‘Ear
Camp’ in northern Namibia, where the population is predominantly black. Medical coverage
for ear problems is poor in this part of the country. Methods: Within 10 days, 38
children (median age 12 years) were operated mainly for (sub) total defects of the
tympanic membrane. In two cases, an open cavity had to be created because of a
cholesteatoma. We performed a tympanoplasty type I in 18 cases and a tympanoplasty type
III in 20 cases. Additionally, in 8 cases an antrotomy and in another 8 cases a
mastoidectomy was performed. The ossicular chain was reconstructed with a titanium-PORP
(14 cases), a titanium- TORP, interposition of the head of the malleus or a cartilage
columella (one case each) or by placing the reconstructed tympanic membrane directly
onto the head of the stapes (three cases). The tympanic membrane was reconstructed by
the use of tragal cartilage with overlapping perichondrium in underlay-technique.
Results: Thirty-one children could be followed up. A defect of the tympanic membrane was
found in five cases because of continuous purulent discharge. The average improvement of
air conduction thresholds in the frequencies between 250 and 4000Hz was 15dB.
Conclusions: Surgical techniques, antibiotic treatment and perioperative management have
to be adapted to limited possibilities of pre-treatment and aftercare. As development
aid should support people to look after themselves, we started to instruct local doctors
with regard to pre- and postoperative care in ear surgery. Training of the local doctors
will be continued in our next ‘Ear Camp’ in 2004. Published courtesy of:Int J Pediatr

Early hearing detection at immunization clinics in developing
countries

Authors: Olusanya BO , Okolo AA
Published: September 2022

Early hearing detection has become a standard of neonatal care in most parts of
the developed world. A growing number of developing countries arc also currently
exploring practical and culturally appropriate options for early hearing detection.
Recent findings from ongoing infant hearing screening programs in Nigeria and South
Africa suggest that hearing screening programs are feasible if integrated into early
childhood immunization programs in developing countries, especially where a significant
number of births occur outside regular hospitals. A major challenge for a multi-stage
screening protocol is how to minimize default rates for follow-up till diagnosis.
However, this could be systematically addressed through improved parental education and
appropriate support at various stages of the program.

Congenital rubella syndrome burden in Morocco: a rapid retrospective
assessment

Authors: Bloom S , Rguig A , Berraho A , Zniber L , Bouazzaoui N , Zaghloul Z , Reef S , Zidouh A , Papania M , Seward J
Published: September 2022

Background: WHO recommends that countries considering introduction of rubella
vaccine into their immunisation programme assess their burden of congenital rubella
syndrome, to determine whether vaccination is warranted. However, few guidelines exist
for such assessments in developing countries. We retrospectively estimated the burden of
congenital rubella syndrome in Morocco, and assessed our methods of rapid case
finding.
Methods: We undertook case finding in the two cities with Morocco’s main
tertiary care referral centres, using medical records from births between Jan 1, 1990,
and May 31, 2002, disability records from 1965 to 1997, and retinal examinations from
deaf students born between 1985 and 1994, applying the WHO definition for a clinically
confirmed case of congenital rubella syndrome. We also reviewed disability data for
evidence of epidemic periodicity and estimated yearly incidence of the syndrome from
congenital cataract data for births between 1990 and 2001.
Findings: We identified
62 clinically confirmed cases of congenital rubella syndrome from medical records, 148
from disability records, and 15 in deaf students. We noted no epidemic periodicity in
disability data, and estimated a yearly incidence of the syndrome in Morocco of 8.1-12.7
cases per 100,000 livebirths.
Interpretation: We show evidence of congenital
rubella syndrome in Morocco and support the addition of rubella vaccination to the
national programme. Various data sources can be explored to rapidly assess burden of the
syndrome; ophthalmology departments and outpatient cardiology clinics could offer the
most potential for such case finding, dependent on documentation practices.

Self-reported outcomes of aural rehabilitation in a developing
country

Authors: Olusanya B
Published: September 2022

The aim of this study was to evaluate self-reported outcomes among hearing aid
users (age 16-89 years; mean 45.8 years) to determine the effectiveness of aural
rehabilitation in Nigeria based on the International Outcome Inventory for Hearing Aids
(IOI-HA). The responses were evaluated with descriptive statistics, factor analysis of
the principal components and multiple regressions. Most respondents reported favorable
outcomes in all domains of the inventory, comprising: daily use (mean 4.1; SD 1.2),
benefits (mean 3.5; SD 1.1), residual activity limitation (mean 3.4; SD 1.2),
satisfaction (mean 3.7; SD 1.2), residual participation restriction (mean 3.5; SD 1.3),
impact on others (mean 3.4; SD 1.3) and changes in quality of life (mean 3.8; SD 1.0).
The mean score distribution compared favorably with those reported in the developed
world. There were significant intercorrelations among all items, and two factors
(eigenvalue>1) accounted for 68% of the underlying variance. Impact on others was the
only domain associated with demographic/audiologic variables. The study showed that
aural rehabilitation is feasible and effective in enhancing activity and participation
for the hearing impaired in a developing country.

Published: September 2022

In the Bolivian Amazon, in a town by the name of Riberalta, exists a wonderful
school for deaf children. The Principal is a highly qualified Swiss deaf person married
to a wonderful deaf woman from Bolivia. The couple have two hearing boys. One evening,
before the children went to bed, the young mother put a cassette tape of German
lullabies for her two little boys to hear. She then looked at the author and asked: “Is
this music beautiful? I put it on every night for our boys to hear because I want them
to grow up also appreciating the culture of their Swiss grandparents”. And the answer
was: “Yes, it is very beautiful!” This happened in 1998 and it has always been an
excellent example of quality education for and of deaf people. These deaf parents were
preparing deaf children and their own hearing children to conquer the world.
Strategy Towards Accurate Location of Seismic Events Sources in Mining Environments: Effect of Voids and Backfill

Published: September 2022

Seismic events may occur naturally or unnaturally as a result of human activity. The focus of this research is on seismicity caused by human activities in underground mines. Despite significant technological advances in the mining industry, the phenomenon of rockburst and its mitigation measures are still controversial technique. Predicting the time of occurrence of rockbursts remains a challenge. At best we can estimate the potential location of seismic events from numerical modelling. Seismic monitoring systems play a major role in the mitigation of rockbursts by identifying their potential source locations. The accuracy of seismic event source locations depends on the reliability of the velocity model. Because the mining environment is constantly changing, a constant input velocity may result in spurious seismic event locations. In this paper physical laboratory models mimicking the continuously changing mining environment are used to investigate the impact of the changing mining environment on seismic wave velocity to provide means for predicting the seismic wave velocity in real-time to improve the accuracy of seismic source locations.

1. INTRODUCTION

Seismicity can occur naturally or be caused by human activity. This study focuses on underground mine seismicity induced by mining operations. A seismic event that occurs suddenly resulting in a damage to an excavation, equipment and or injury to personnel is known as a rockburst (Zhou, Li & Mitri, 2018). Rockbursts are a common problem in deep underground mines and affect mine operations in terms of safety, productivity and efficiency. Predicting the time of rockburst occurrence is difficult due to its complex nature. The only way to deal with the problem is to identify possible locations of rockburst occurrence through site experience or numerical modelling (Trifu & Suorineni, 2009).

Microseismic monitoring systems are common tools used for monitoring seismicity for the estimation of different hazard sources. These equipment are widely used in deep underground mines and are vital to control and mitigate the risks caused by seismicity. The microseismic monitoring system helps to detect, locate and identify seismic events in underground mines, and therefore they are essential part of the rockburst understanding mechanism.
Analytical Model to Effective Permeability Loss Monitoring and Boundary Effects Identification in Oil Wells with Finite Hydraulic Fractures
Authors: Fernandes F. B. , Braga A. M. B. , Souza A. L. S. , Soares A. C.
Published: September 2022

Hydraulic fracturing technology has been used by petroleum industry to solve a variety of problems and providing the understanding for many of difficult issues. This work presents a new analytical model to evaluate the effective permeability response during the oil’s production through a vertical well fully penetrating a pressure-sensitive reservoir with a finite extent hydraulic fracture. The nonlinear hydraulic diffusivity equation (NHDE) is solved analytically through an integro-differential model coupled to Green’s function (GF) related to an oil source plan that represents the finite hydraulic fracture. A new effective hydraulic diffusivity deviator factor is also derived to represent the permeability loss as function of the pore pressure throughout the well-reservoir life-cycle. For this oil flow modeling, the general solution is expressed by the sum of the linear solution (constant permeability) plus a corrective term given by the combination of the exponential function Ei(xD,yD,tD) and the complementary error function erfc(xD,yD,tD). The proposed model is implemented in Matlab software to evaluate the effect of the effective deviator factor in the permeability response over the oil’s production’s period. The model calibration is performed through a numerical oil flow simulator, widely used in the petroleum industry and scientific works and the results were accurate.

1 INTRODUCTION

Reservoir stimulation techniques e.g. acidizing, acid and hydraulic fracturing are used to make the production’s curve economically attractive (Fernandes, 2021a,b; Fernandes et al., 2021a). These techniques are also used to improve the oil production curve when the reservoir permeability drops and the minimum viable oil flow rate is reached.

Hydraulically fractured petroleum reservoirs may increase significantly the oil production’s curve and make many projects more attractive economically (Almisned and Al-Awad, 2017; Miskimins, 2019). Various works related to proppant transport and hydraulic fractures behavior in conventional and unconventional pressure-sensitive oil reservoirs have been published to reach the maximum stimulated reservoir volume to improve the oil recovery (Miskimins, 2019; Miskimins and Alotaibi, 2019). There-with, hydraulic fracturing is a continuously evolving well stimulation method to enhance, accelerate and restore production by reducing the oil flow-path resistance from the porous media to the well (Howard and Fast, 1957; Zoback and Haimson, 1982; Warpinski et al., 1981a,b, 1982a,b, 1985, 1993, 1998; Gringarten, 2008; Economides and Noltes, 2000; Miskimins, 2019; Miskimins and Alotaibi, 2019).
Effect of Parent Well Production on Wellbore Breakout of Child Well in Coalbed Methane Reservoirs

Published: September 2022

The accurate estimation of parent well production induced in-situ stress change is of great significance for evaluating wellbore breakout of child wells. For conventional reservoirs, poromechanical effect is considered to be the main factor that controls in-situ stress evolution. However, for coalbed methane (CBM) reservoirs, gas desorption-induced coal shrinkage also contributes to the stress change, which is rarely included in the theoretical models. In this work, the in-situ stress evolution during coalbed depletion is first investigated through combining the effect of poromechanics and gas desorption. Then, the calculated stresses are incorporated into the geomechanical model to analyze the effect of gas desorption-induced coal shrinkage on wellbore breakout of child wells. The obtained results indicate that with pore pressure decreasing, both the maximum and minimum horizontal stresses decrease at a larger rate when gas desorption effect is considered. For vertical wellbore section of child wells, the larger Langmuir strain leads to the smaller breakout length and width, while for horizontal wellbore section of child wells, the larger Langmuir strain leads to the larger breakout length and smaller breakout width. The modeling results offer new insights for understanding the wellbore breakout of child wells in CBM reservoirs.

1. INTRODUCTION

With the worldwide energy consumption rate steadily increasing, more drilling practices are taken place in the mature oil and gas fields (Yang and Liu, 2021). For instance, in CBM reservoirs, infill-wells are drilled and stimulated around the parent-wells to improve the production performance of the depleted formation (Salmachi et al., 2013). When an infill-well is drilled, stress concentration will occur around the borehole which may damage the rocks if the concentrated stress exceeds the rock strength (Zoback et al., 1985). Breakout is a typical type of wellbore instability problem during the drilling process (Mohammadali et al., 2021) and, in vertical wells, borehole enlargement orientation is consistent with the minimum horizontal stress direction, as shown in Fig. 1. However, in depleted reservoirs, pore pressure decline alters the original in-situ stresses and thus the stresses around the wellbore. Therefore, drilling mud weight window changes for the new wells and also the wellbore breakout shape will be different from the old ones.
