Published: January 2022

Contextualización: El café se cultiva en el 64 % de los municipios de Nariño, donde la variabilidad climática es adecuada para que la planta pueda realizar sus actividades metabólicas.
Vacío de conocimiento: El desconocimiento y la falta de estudios relacionados con la respuesta de los componentes de rendimiento, en diferentes ambientes, dificulta interpretar las variables que influyen en el rendimiento del café variedad Castillo.
Propósito: El objetivo fue establecer la relación causa-efecto entre variables relacionadas con los componentes morfológicos, fisiológicos y climáticos del rendimiento del café, variedad Castillo, considerando tres condiciones altitudinales (Alta-A = 2015 msnm, Media-M = 1700 msnm y Baja-B= 1536 msnm).
Metodología: El trabajo se realizó en el municipio de Sandoná, departamento de Nariño. Las variables registradas incluyeron: radiación fotosintéticamente activa, temperatura ambiente, precipitación, humedad relativa, altura de planta, número de hojas, diámetro basal del tallo, número de ramas primarias, longitud de ramas primarias, número de entrenudos por rama, largo de la hoja, área foliar e índice de área foliar. Estas se evaluaron a través del Análisis de Sendero. 
Resultados y conclusiones: Los componentes de rendimiento en el cultivo de café de la variedad Castillo variaron con la altitud. Las zonas M y B obtuvieron los rendimientos más altos. Para la altitud M (1700 msnm), los efectos directos sobre el rendimiento (RTO) los tuvo la variable ramas primarias (RP). Dentro de los efectos indirectos, los más importantes fueron los causados por humedad relativa (RH) a través de la temperatura (T). La altitud B (1536 msnm) presentó efectos directos en el largo de rama (LR), área foliar (AF) y Radiación Fotosintéticamente Activa (RFA); y los efectos indirectos estuvieron en la T a través de la RFA, el número de entrenudos (NE) a través de la altura de planta (AP), el diámetro basal (DB) a través del número de hojas (NH), el RP a través de la longitud de la hoja (LH), AF y   HR. La zona con menor rendimiento fue la altitud A (2015 msnm), mostrando como efectos directos AP, NE y HR; y los indirectos, NH, DB, LR y AF a través de AP. Es necesario estudiar la arquitectura de la planta y su relación con la HR para potenciar el RTO del café.

Abstract Background: The level of pollen in Korea has increased over
recent decades. Research suggests that pollen-food allergy syndrome
(PFAS) may be more frequent in childhood than previously recognized. We
aimed to investigate the prevalence and characteristics of PFAS in
children aged 6–10 years from a general population-based birth cohort.
Methods: We analyzed 930 children from the COhort for Childhood Origin
of Asthma and allergic diseases (COCOA) birth cohort. Allergic diseases
were diagnosed annually by pediatric allergists. The skin prick tests
were performed with 14 common inhalant allergens and four food allergens
for children aged 3 and 7 years. Results: Of the 930 eligible children,
44 (4.7%) aged 6–10 years were diagnosed with. The mean age at onset
was 6.74 years. PFAS prevalence was 7.2% among children with allergic
rhinitis (AR) and 19.1% among those with pollinosis, depending on
comorbidity. PFAS was more prevalent in schoolchildren with atopic
dermatitis, food allergy, and sensitization to food allergens and grass
pollen in early childhood. In schoolchildren with AR, only a history of
food allergy before 3 years increased the risk of PFAS (aOR 2.971, 95%
CI: 1.159–7.615). Conclusion: Food allergy and food sensitization in
early childhood was associated with PFAS in schoolchildren with AR.
Further study is required to elucidate the mechanism by which food
allergy in early childhood affects the development of PFAS.

Published: January 2022

Endometriosis is a chronic and relatively common disease in women of
childbearing age. Complications of this disease include a wide range of
disorders. The cause of this disease is not known for sure, but several
hypotheses have been proposed for it. In this disease, the entry of
endometrial tissues into the peritoneal cavity causes oxidative stress
through the Fenton reaction and inflammation in this site. Oxidative
stress can be associated with many complications of endometriosis. In
this review, an attempt has been made to discuss the effects of
oxidative stress on various complications of this disease.

Introduction: Larger left atrial appendage (LAA) ostium area
and greater left atrial (LA) volume have been associated with an
increased risk of ischemic stroke. Catheter ablation (CA) of atrial
fibrillation (AF) leads to morphological and functional changes within
the LA and LAA, some of which are not well studied. Here, we present
findings regarding post-ablation changes of the LAA ostia and correlate
them with various LA, LAA and left ventricular (LV) functional and
morphological metrics. Methods: This retrospective analysis
included patients scheduled to undergo first-time radiofrequency CA for
AF. Catheter ablation techniques included PVI with or without additional
ablations. Cardiac magnetic resonance imaging (CMR) was used to assess
LA, LAA and LV morphology and function, including LAA ostium area,
LA/LAA volume and volume index, LA ejection fraction, LA strain, and LV
ejection fraction. A Kruskal-Wallis test was used for correlating LAA
ostial dimensions with other LA morphological and functional metrics.
The t-test or two-sample Wilcoxon test were used to compare LA and LAA
morphological parameters. Results: A total of 101 patients with
AF were included in this study. The mean age was 60.1 ± 11.1 years, 69%
were male, the average BMI was 29.22 ± 5.08. The LAA ostial area reduced
significantly from 3.84 ± 1.15 cm before ablation to
3.42 ± 0.96 cm after ablation (p=0.0004). This
reduction was asymmetrical, as the minor axis length decreased from 1.92
cm to 1.77 cm without significant changes in the major axis. LVEF
increased from a pre-ablation average of 48.26% to a post-ablation
average of 53.62% (p=0.015). Correlation of pre-ablation LVEF and LAA
ostium area showed a near-significant negative trend (r=-0.21, p=0.083).
LAEF correlated negatively with LAA ostial area (r=-0.289, p=0.0057),
total LA strain (r=-0.248, p=0.0185), and passive LA strain (r=-0.208,
p=0.049). Conclusion: There is a significant asymmetrical
reduction of the LAA ostial area after AF ablation that is independent
of LVEF changes. Larger LAA ostial area was associated with lower LAEF
and LA strain. Remodeling of the LAA after AF ablation may help account
for reduced risk of stroke and increased cardiac function.

1.Herbaceous aboveground biomass (HAB) is a key indicator of grassland
vegetation and indirect estimation tools, such as remote sensing
imagery, increase the potential for covering larger areas in a timely
and cost-efficient way. Structure from motion (SfM) is an image analysis
process that can create a 3D model from a set of images. 2: Computed
from UAV and ground camera measurements, the SfM potential to estimate
the herbaceous aboveground biomass in Sahelian rangelands was tested in
this study. Both UAV and ground camera recordings were used at three
different scales: temporal, landscape and national (across Senegal). All
images were processed using PIX4D software and were used to extract
vegetation indices and heights. 3: A random forest algorithm was used to
estimate the HAB and the average estimation errors were around 150 g.m-²
for fresh mass (20% relative error) and 60 g.m-² for dry mass (around
25% error). A comparison between different datasets revealed that the
estimates based on camera data were slightly more accurate than those
from UAV data. 4:It was also found that combining datasets across scales
for the same type of tool (UAV or camera) could be a useful option for
monitoring HAB in Sahelian rangelands or in other grassy ecosystem.

Published: January 2022

Objective: Fat content and volume of liver and pancreas
are associated with risk of diabetes in observational studies; whether these
associations are causal is unknown. We conducted a Mendelian randomization (MR)
study to examine causality of such associations.

Research design and methods: We used genetic variants associated (p <
5×10−8) with the exposures (liver and pancreas volume and fat
content) using MRI scans of UK Biobank participants (n=32,859). We obtained summary-level
data for risk of type 1 (9,358 cases) and type 2 (55,005 cases) diabetes from
the largest available genome-wide association studies. We performed inverse-variance
weighted MR as main analysis and several sensitivity analyses to assess
pleiotropy and to exclude variants with potential pleiotropic effects.

Results: Observationally, liver fat and volume were
associated with type 2 diabetes (odds ratio (OR) per one standard deviation
(SD) higher exposure 2.16 [2.02 - 2.31] and 2.11 [1.96, 2.27], respectively). Pancreatic
fat was associated with type 2 diabetes (1.42 [1.34, 1.51]) but not type 1
diabetes, and pancreas volume was negatively associated with type 1 diabetes
(0.42 [0.36, 0.48]) and type 2 diabetes (0.73 [0.68, 0.78]). MR analysis
provided evidence only for a causal role of liver fat and pancreas volume on
risk of type 2 diabetes (1.27 [1.08,1.49] or 27% increased risk and 0.76
[0.62,0.94] or 24% decreased risk per 1SD, respectively) and no causal
associations with type 1 diabetes.

Conclusions: Our findings assist in understanding the
causal role of ectopic fat in the liver and pancreas and of organ volume in the
pathophysiology of type 1 and 2 diabetes.

The article specifies the forms of medical intervention in relation to a healthy person and further examines the criminal legal limits of the implementation of appropriate medical manipulations.
Advanced characterisation of microstructural evolution and liquation mechanisms in RR1000 employing a novel semi-solid testing facility
Authors:   , John Sean E.
Published: January 2022

Inertia friction welding is a joining technique that is used in many industries as it can create high quality welds with narrow heat affected zones. The nickel superalloy RR1000 is routinely joined via inertia friction welding, during the manufacture of compressor components for gas turbine engines, at Rolls-Royce Plc. The conditions experienced at the weld interface of an inertia friction weld are extreme, with a combination of rapid heating rates to high temperatures and severe strain rates. These conditions are such that liquation of RR1000 is to be expected. The liquation mechanisms of two variants of RR1000 have been investigated, building on previous research, to further understand the dynamic evolution of microstructure and mechanical properties during inertia friction welding of RR1000. This investigation was accomplished by the design and commissioning of a novel semi-solid testing facility. The facility underwent numerous modifications to allow representative replication of the conditions experienced during inertia friction welding. To investigate the liquation mechanisms occurring in RR1000, fine grain and coarse grain compression specimens were heated to temperatures between 900°C and 1200°C at heating rates between 1°Cs-1 and 25°Cs-1. The fine grain and coarse grain variants were found to liquate via two mechanisms. The fine grain primarily experienced constitutional liquation of the primary γ’ precipitates, while incipient melting of the γ phase was experienced by the coarse grain variant. The liquid propagation rate in both variants was characterised. The knowledge and understanding gained via the use of this facility was then applied to analyse the microstructures from a series of interrupted RR1000 inertia friction welds. Inspection of these interrupted welds revealed evidence of liquation like that observed in the specimens tested in the semi-solid testing facility. This research has given an insight into the role of liquation during inertia friction welding of RR1000.

Nursing Care of Low-Risk Newborns in Low Resource Setting: Nurses' Aides May Bridge the Gap at Community Hospitals
Authors: Daga Subhashchandra
Published: January 2022

Objective: To study the role of a nurses' aide in the care for newborns weighing between 1500 and 2000 g at birth in a low resource setting.

Study Design: Observational.

Setting: The General hospital in 1994-95, in a public sector, located in a remote area in India

Intervention: A female ward assistant with seven years of schooling trained, on-the-job, to keep babies warm, initiate maternal breastfeeding, and to detect rapid breathing. The nursing staff from the pediatric ward supervised her performance. A separate "warm room" appropriately heated for preterm and sick babies became a makeshift nursery. The nursing staff administered enteral feeding, oxygen, and antibiotics. Services of the resident doctors or general duty medical officers were not available.

Results: The survival rate was nearly 100% for babies with birthweights between 1,500 and 2,000 g (none referred out).

Conclusions: A nurses' aide may facilitate the delivery of special care for newborns where nursing personnel are grossly inadequate and saving babies weighing between 1,500 and 2,000 g may need minimal inputs. It may be worthwhile to target 1,500 and 2,000 g birthweight categories even when resources are meager.

What is already known about this subject?

Low resource settings face staff shortages, especially nursing staff.

Health workers with midwifery skills can deliver nearly 90% of essential care services for maternal and neonatal health.

A substantial proportion of neonatal deaths occur among moderately low birth weight babies.

What does this study add?

It is possible to train a semi-literate person to facilitate early breastfeeding and to keep a baby warm.

A large proportion of deaths among babies with birthweight ranging from 1500 to 2000 g are preventable with meager resources.

How might this impact on clinical practice or future developments?

The facilities facing shortage of nursing staff in low resource settings, may employ nurses’ aide to deliver basic newborn care.

Published: January 2022

The spread of Diseases like Cholera and Diarrhea, which leads to loss of lives in developing countries is commonly caused by use of contaminated water. In this study ceramic pot filters for rural area water purification were developed. The clay sample was tested for physical properties and the mixtures of the clay and sawdust were made in seven (7) proportions of 75/25, 70/30, 65/35, 60/40, 55/45, 50/50, 45/55. The soil tests conducted on the different portions of the clay and sawdust material revealed that the shrinkage of the sawdust blended clay reduced to the minimum of 6.3 compared to the pure clay with 13.7. A fluid dynamic test experiment on each filter was conducted; similarly total dissolved solids (TDS), pH and turbidity tests for both raw water and filtered water were conducted. From fluid dynamic test results, filter 50/50 % tends to have higher filtration rate compared to the other two filters. From the TDS, pH, and turbidity test, the results obtained show that the filtered water quality has fallen within the world health organization (WHO) standard. It can therefore be concluded that the filtered water is safe for consumption.
Controlling Factors of the Particle Size of Spherical Silica Synthesized by Wet and Dry Processes
Authors: Saiki Keiji , Ishikawa Toshihiro
Published: January 2022

We clarified the controlling factors of the particle size of the amorphous silica synthesized by wet and dry processes. In the wet process using methyl-trimethoxy-silane as a starting monomer, the obtained particle size can be easily controlled by changing the reaction time appropriately. However, to obtain larger particles, a relatively long time is needed. After the condensation reaction was conducted for 50h, the silica particles (D50: 3μm) were synthesized by calcination at 550oC in air. To synthesize larger silica particles, we used silica-seed particles (8μm) to obtain very large spherical silica particles (D50: 20μm). Thus, although the wet process needs a relatively long reaction time, it is very useful for synthesizing spherical silica particles with a wide range of particle size. In the dry process, we used methyl-trimethoxy-silane (MTMS), tetra-ethoxy-silane (TEOS), and octamethyl-cyclotetrasiloxane (OMCTSO) as the starting materials. In this process, the size of the silica particles was dominated by the molecular structure of the monomer, in particular, the number of silicon atoms contained in the monomer and the bulkiness of the substituent group. The largest silica particles were synthesized from OMCTSO, which contains the largest number of silicon atoms.
Effect of Hydrological Data on Flood Management in Urban Areas
Authors: Sumiharni . , Afriani Lusmeilia
Published: January 2022

Floods can occur due to rising water levels due to above-normal rainfall, changes in temperature, broken embankments/dams, rapid snowmelt, obstruction of water flow in other places, and putting people at risk of annual disasters due to flooding. The purpose of this study was to obtain a more detailed description of hydrological conditions so that flooding in the Bandar Lampung urban area can be optimally managed or controlled. The method used in flood control research is the analysis of the calculation of the average rainfall in the watershed, and the calculation of the planned discharge. The results of the analysis show that the existing drainage channels that have been carried out for each channel point have dimensions that are not large enough so that they are not sufficient to accommodate water runoff. so that for a 5-year discharge of 28.058 m3/s, the dimensions of the channel are 3 m wide and 2.6 m deep and for a 10-year discharge of 30.609 m3/s, the channel dimensions are 3.1 m wide and 2.7 m deep.

Authors: Dinwoke Onodagu P. , Henry Aginam C. , Franklin Uzodinma C.
Published: January 2022

This paper analysed the flexural behaviour of SSSS thick isotropic rectangular plates under transverse load using the Ritz method. It is assumed that the line that is normal to the mid-surface of the plate before bending does not remain the same after bending and consequently a shear deformation function f (z) is introduced. A polynomial shear deformation function f (z) was derived for this research. The total potential energy which was established by combining the strain energy and external work was subjected to direct variation to determine the governing equations for the in – plane and out-plane displacement coefficients. Numerical results for the present study were obtained for the thick isotropic SSSS rectangular plates and comparison of the results of this research and previous work done in literature showed good convergence. However, It was also observed that the result obtained in this present study are significantly upper bound as compared with the results of other researchers who employed the higher order shear deformation theory (HSDT), first order shear deformation theory (FSDT) and classical plate theory (CPT) theories for the in – plane and out of plane displacements at span – depth ratio of 4. Also, at a span - depth ratio of  and above, there was approximately no difference in the values obtained for the out of plane displacements and in-plane displacements between the CPT and the theory used in this study.

The content of four heavy metals (zinc, iron, chromium and copper) in muscles, liver and gonads has been studied for the five most consumed fish species (Cephalopholus taeniops, Scomber japonicus, Lagocephalus laevigatus, Pagellus bellottii and Pagrus caeruleostictus) in the Soumbedioune region. The samples were digested by acid digestion. The metal contents were quantified using a PF-11 type photometer. The results obtained show that metals such as zinc, iron and chromium are significantly higher (p <0.05) in the muscles of the four species than in the liver and gonads. However, the levels of heavy metals in the muscles, liver, and gonads of the five species are above the acceptable limit recommended by the FAO and WHO, with the exception of the copper levels in the gonads of the species Pagellus bellottii.

The world population is continuously growing at a rapid rate, so a great challenge for this time is to ensure the security of food and nutrition for this increased population seeking for new crop as a source of food and nutrition. In such state mushrooms, a great source of protein, can be a favor that can be cultivated by landless people using agricultural waste material. The research work was about to analyze the effect of three lighting conditions namely dark condition (C1), medium lighting condition (C2), and sunlight (C3) on growth, yield, and nutrient content of pleurotus ostreatus (white oyster mushroom). Vertical farming technology was applied in mushroom production in order to minimize the land use. Three vertical structures each of three layers were used. This study also encompassed the effects of different layers (bottom later L1, middle layer L2, top layer L3) on the growth and yield of mushroom. The findings of this investigation revealed that there were significant differences in growth and yield at different conditions and structural layers. The highest average growth and yield (stalk height 3.87 cm, cap size 11.89 cm, stipe size 2.65 cm, crops per bag 15.78, fresh weight 60.03 g, and dry weight 17.03 g) was observed in dark condition (C1). On the other hand, lowest growth, and yield (stalk height 1.59 cm, cap size 3.67 cm, stipe size 1.51 cm, crops per bag 4.22, fresh weight 18.38 g, and dry weight 4.47 g) was found in sunlight (C3). Oyster mushroom cultivated in dark condition C1 also have high nutrient content. The study suggested that maintaining the absolute darkness is capable of producing high-quality white oyster mushroom.

The livestock farming especially dairy industry is among the important components of the livestock sector in Zanzibar in terms source of animal protein, income, and employment. The present study was meant to investigate milking hygiene and handling practices among smallholder dairy farmers in Zanzibar. Cross-sectional study was conducted whereby a structured questionnaire was addressed to 359 dairy cattle farmers. The assessment of milking hygiene and handling practices among smallholder dairy farmers on were analyzed and then judged based on the selected indicators of good dairy farming practices of FAO and International Dairy Federation (IDF) and IDF, (FAO, 2011) and Zanzibar Food and Drug Board standard. The results revealed low milking hygiene and good handling practices. In addition, based on the Zanzibar Food and Drug Board’ standards, farmers comply lowly with milk quality standards and food safety regulations. It was also found that farmers, traders and processors practised milking hygiene and handling measures like hand washing, udder and utensils cleaning milking boiling and packaging. However, key un-hygiene practices include the use of plastic containers, untreated water, and lack of teat dipping. It is recommended that, for safe and quality milk availability, farmers must be equipped with knowledge and skills on good milking hygiene and handling practices. There is a need to improve farmers’ knowledge and implement hygienic milking practices in the milk production process to meet required milk quality and food safety standards. In addition, awareness creation on the importance of good milking and handling practices will create behavioural change and lead to an improvement in milk quality in Zanzibar.

The aim of this study was to analyse the risk coping strategies among catfish farmers in Ikorodu division of Lagos State, Nigeria. Primary data were obtained from 100 catfish farmers with the aid of a pre-tested questionnaire and focus group discussion using multistage sampling technique. Descriptive statistics and multivariate probit regression model were employed for data analysis. Results revealed that majority (68.1%) of the respondent were male with a mean age of 41 years and a mean stock size of 1130. The major sources of risks in the study area were fluctuation in price (89.4%), cost and quality of feed (79.8%), high cost of labour (76.6%), quality of fingerling (75.6%), bird invasion (75.6%) among others. Reduced volume of stock (87.2%), treated pond before stocking (77.7%), purchased good feed quality (74.5%), and used personal savings (72.3%) were the major coping strategies adopted by the farmers in the study area. The estimate of the multivariate probit regression model revealed that sex, age, education, household size, catfish experience, start-up capital, farming status, membership of cooperative association and access to loan were the factors determining the adoption of risk coping strategies in the study area. Therefore, government, both at the federal and state level should intensify efforts at implementing the various agricultural support programs such as anchor borrowers, poverty alleviation fund and other subsidy programs that can help the farmers expand their capital base and better cope with risk in the study area.

Price stability is the primary monetary policy objective in any economy since it protects the interests of both consumers and producers. As a result, forecasting is a common practice and a vital aspect of monetary policymaking. Future predictions guide monetary and fiscal policy tools that that be used to stabilize commodity prices. As a result, developing an accurate and precise forecasting model is critical. The current study fitted and forecasted the food and beverages price index (FBPI) in Kenya using seasonal autoregressive integrated moving average (SARIMA) models. Unlike other ARIMA models like the autoregressive (AR), Moving Average (MA), and non-seasonal ARMA models, the SARIMA model accounts for the seasonal component in a given time series data better forecasts. The study relied on secondary data obtained from the KNBS website on monthly food and beverage price index in Kenya from January 1991 to February 2020. R-statistical software was used to analyze the data. The parameter estimation was done using the Maximum Likelihood Estimation method. Competing SARIMA models were compared using the Mean Absolute Error (MAE), Mean Absolute Scaled Error (MASE),.and Mean Absolute Percentage Error (MAPE). A first-order differenced SARIMA (1,1,1) (0,1,1)12 minimized these model evaluation criteria (AIC = 1818.15, BIC =1833.40). The forecasting ability evaluation statistics MAE = 2.00%, MAPE = 1.62% and MASE = 0.87%. The 24-step ahead forecasts showed that the FPBI is unstable with an overall increasing trend. Therefore, the monetary policy committee ought to control inflation through monetary or fiscal policy, strengthening food security and trade liberalization.
Multi-Modal Oral Implantology. The Screw-Blade Single-Implant for the Replacement of the Upper Molar: A Case Report
Authors: Dal Carlo Luca , Dal Carlo Zeno , Pasqualini Marco E. , Rossi Franco , Shulman Mike
Published: January 2022

Intense forces are naturally downloading on molar roots. Due to inflammation, the post-extraction sockets of the upper molars are often poor of bone on one side. A single implant supporting a prosthetic crown can easily go subject to displacing forces that reabsorbed and recently healed bone can hardly bear. By utilizing a couple of prosthetic roots, i.e.: one screw implant in the side in which bone is richer and one blade implant in the side in which the bony wall has gone subject to reabsorption, it is possible to build a better supported prosthetic crown. The clinical cases performed by the Authors confirm the validity of this implant architecture.

Aim of the work is to describe a post-extraction multi-modal implantological technique useful for replacing the roots of upper molars with poor bone support on one side.

Materials and Methods: Combination of submerged screw implant and submerged blade implant or emergent screw implant and emergent blade implant welded intraorally.

Discussion: The combination of a palatal screw implant and a buccal blade implant, or vice versa, allowed to solve clinical cases and to make reliable prosthetic crowns.

Conclusions: The presence of variable residual anatomies in the molar area of the upper jaw recommends the use of morphologically different implant shapes, suitable for the construction of a biomechanically functional prosthetic abutment. Specifically in the presence of bone resorption, the combination of a screw implant and a blade implant allowed us to obtain a reliable abutment. Given the small number of cases performed, further research will confirm the positive results of this technique.

Cataracts are the second most common cause of blindness in the world at 33%. The incidence of cataracts is 0.1% of the total population, so the number of new cataract cases in Indonesia is estimated at 250,000 per year. This study aims to compare the visual acuity of post cataract surgery patients with Small Incision Cataract Surgery and Phacoemulsification techniques at Sanjiwani Hospital, Gianyar. This study was a retrospective cohort at Ophthalmologist’s Outpatient Departement of Sanjiwani Hospital, Gianyar, Bali. The sample of this study was 60 patients with 84 eyes with senile cataract. The surgical techniques performed were Small Incision Cataract Surgery (53.6%) and Phacoemulsification (46.4%). After that, an Uncorrected Visual Acuity (UCVA) examination was carried out on day 1 and day 42. The result were cataract patients at Sanjiwani Hospital, Gianyar aged 60-65 years who were male. Comparison of visual acuity after Small Incision Cataract Surgery and Phacoemulsification had the same results. On day 1 and day 42, there was no different uncorrected visual acuity result between Small Incision Cataract Surgery and Phacoemulsification statistically.

As we know, the Philadelphia chromosome (Ph) is a highly specific marker for chronic myeloid leukemia (CML). This hematological disease is characterised by the formation of the BCR/ABL1 fusion gene, usually with typical translocation pattern including 9q34 and 22q11. In this paper we describe a 55 years old female patient with typical clinical and haematological signs of CML and a chromosome 9 differing from that which normally participates in translocation t(9;22). The karyotype of this Ph positive patient is characterised by pericentric inv(9)(p13q34) of the der(9)t(9;22)(q34;q11). Reverse transcriptase-polymerase chain reaction revealed a e14a2 type of BCR/ABL1 fusion transcript. As a consequence of this unusual translocation, FISH also found the separation of the ABL1/BCR1 fusion gene on chromosome 9. On reviewing the literature, to date only 10 Ph-positive leukemia patients have been noticed to have pericentric inversion inv(9)(p22q34)der(9)t(9;22)(q34;q11). No one case has been described with pericentric inversion inv(9)(p13q34) of the der(9)t(9;22)(q34;q11). This indicate that pericentric inv(9)(p13q34) of the der(9)t(9;22)(q34;q11) is a novel, rare, chromosomal abnormality in Ph-positive CML.
