RESUMEN
Inflammatory skin diseases are known to negatively impact patient psychology, with individuals experiencing higher rates of stress and subsequent diminished quality of life, as well as mental health issues including anxiety and depression. Moreover, increased psychological stress has been found to exacerbate existing inflammatory skin diseases. The association between inflammatory skin diseases and psychological stress is a timely topic, and a framework to better understand the relationship between the two that integrates available literature is needed. In this narrative review article, we discuss potential neurobiological mechanisms behind psychological stress due to inflammatory skin diseases, focusing mainly on proinflammatory cytokines in the circulating system (the brain-gut-skin communications) and the default mode network in the brain. We also discuss potential descending pathways from the brain that lead to aggravation of inflammatory skin diseases due to psychological stress, including the central and peripheral hypothalamic-pituitary-adrenal axes, peripheral nerves and the skin barrier function.

Aims: Pulmonary atresia with intact ventricular septum (PA/IVS) can be treated by catheter-based interventions and complemented by various surgical procedures. We aim to determine a long-term treatment strategy to enable patients to be surgery free, depending solely on percutaneous interventions. Methods and Results: We selected five patients from among a cohort of patients with PA/IVS treated at birth with radiofrequency perforation and dilatation of the pulmonary valve. Patients had reached a pulmonary valve annulus of 20 mm or larger on their biannual echocardiographic follow-up, with right ventricular dilatation. The findings, together with the right ventricular outflow tract and pulmonary arterial tree, were confirmed by multislice computerised tomography. Based on the angiographic size of the pulmonary valve annulus, all patients were successfully implanted with either Melody® or Edwards® pulmonary valves percutaneously, regardless of their small weights and ages. No complications were encountered. Conclusion: We managed to stretch the age and weight limitations for performing percutaneous pulmonary valve implantation (PPVI): interventions were attempted whenever a pulmonary annulus size of >20 mm was reached, which was rationalised by the prevention of progressive right ventricular outflow tract dilatation and accommodating valves between 24 and 26 mm, which is enough to sustain a normal pulmonary flow in adulthood.

PURPOSE: Ureteroenteric anastomosis after cystectomy is usually performed using the Bricker or Wallace technique. Deterioration of renal function is the most common long-term complication of urinary diversion (UD). To improve surgical care and optimize long-term renal function, we compared the Bricker and Wallace anastomotic techniques and identified risk factors for ureteroenteric strictures (UES) in patients after cystectomy. MATERIAL AND METHODS: Retrospective, monocentric analysis of 135 patients who underwent cystectomy with urinary diversion at the University Hospital Essen between January 2015 and June 2019. Pre- and postoperative renal function, relevant comorbidities, prior chemo- or radiotherapy, pathological findings, urinary diversion, postoperative complications, and ureteroenteric strictures (UES) were analyzed. RESULTS: Of all 135 patients, 69 (51.1%) underwent Bricker anastomosis and 66 (48.9%) Wallace anastomosis. Bricker and Wallace groups included 134 and 132 renal units, respectively. At a median follow-up of 14 (6-58) months, 21 (15.5%) patients and 30 (11.27%) renal units developed UES. We observed 22 (16.6%) affected renal units in Wallace versus 8 (5.9%) in Bricker group (p < 0.001). A bilateral stricture was most common in Wallace group (69.2%) (p < 0.001). Previous chemotherapy and 90-day Clavien-Dindo grade ≥ III complications were independently associated with stricture formation, respectively (OR 9.74, 95% CI 2-46.2, p = 0.004; OR 4.01, 95% CI 1.36-11.82, p = 0.013). CONCLUSION: The results of this study show no significant difference in ureteroenteric anastomotic techniques with respect to UES development regarding individual patients but suggest a higher risk of bilateral UES formation in patients undergoing Wallace anastomosis. This is reflected in the increased UES rate under consideration of the individual renal units.

The modification of chitosan represents a challenging task in obtaining biopolymeric materials with enhanced removal capacity for heavy metals. In the present work, the adsorption characteristics of chitosan modified with carboxyl groups (CTS-CAA) towards copper (II) and zinc (II) ions have been tested. The efficacy of the synthesis of CTS-CAA has been evaluated by studying various properties of the modified chitosan. Specifically, the functionalized chitosan has been characterized by using several techniques, including thermal analyses (differential scanning calorimetry and thermogravimetry), spectroscopies (FT-IR, XRD), elemental analysis, and scanning electron microscopy. The kinetics and the adsorption isotherms of CTS-CAA towards both Cu (II) and Zn (II) have been determined in the aqueous solvent under variable pH. The obtained results have been analyzed by using different adsorption models. In addition, the experiments have been conducted at variable temperatures to explore the thermodynamics of the adsorption process. The regeneration of CTS-CAA has been investigated by studying the desorption process using different eluents. This paper reports an efficient protocol to synthesize chitosan-based material perspective as regenerative adsorbents for heavy metals.

Streptococcus gordonii is a commensal oral organism. Harmless in the oral cavity, S. gordonii is an opportunistic pathogen. S. gordonii adheres to body surfaces using surface adhesive proteins (adhesins), which are critical to subsequent formation of biofilm communities. As in most Gram-positive bacteria, S. gordonii surface proteins containing the C-terminal LPXTG motif cleavage sequence are processed by sortase A (SrtA) to become covalently attached to the cell wall. To characterize the functional diversity and redundancy in the family of SrtA-processed proteins, an S. gordonii DL1 markerless deletion mutant library was constructed of each of the 26 putative SrtA-processed proteins. Each library member was evaluated for growth in rich medium, biofilm formation on plastic, saliva and salivary fractions, cell surface hydrophobicity (CSH), hemagglutination, and integration into an ex vivo plaque biofilm community. Library members were compared to the non-SrtA-processed adhesins AbpA and AbpB. While no major growth differences in rich medium were observed, many S. gordonii LPXTG/A proteins impacted biofilm formation on one or more of the substrates. Several mutants showed significant differences in hemagglutination, hydrophobicity, or fitness in the ex vivo plaque model. From the identification of redundant and unique functions in these in vitro and ex vivo systems, functional stratification among the LPXTG/A proteins is apparent.IMPORTANCES. gordonii interactions with its environment depend on the complement of cell wall proteins. A subset of these cell wall proteins requires processing by the enzyme sortase A (SrtA). The identification of SrtA-processed proteins and their functional characterization will help the community to better understand how S. gordonii engages with its surroundings, including other microbes, integrates into the plaque community, adheres to the tooth surface, and hematogenously disseminates to cause blood-borne infections. This study identified 26 putative SrtA-processed proteins through creation of a markerless deletion mutant library. The library was subject to functional screens that were chosen to better understand key aspects of S. gordonii physiology and pathogenesis.

BACKGROUND: A variety of minimally invasive techniques are available for the treatment of varicose great saphenous vein (GSVs). Non-tumescent, non-thermal ablation methods have been developed. This study compared mechanochemical ablation (MOCA), a non-tumescent, non-thermal ablation technique, with two endovenous thermal ablation methods requiring tumescence in an RCT. METHODS: Patients with GSV reflux were randomized to undergo MOCA, or thermal ablation with endovenous laser (EVLA) or radiofrequency (RFA). The primary outcome measure was the occlusion rate of the GSV at 1 year. RESULTS: The study finally included 125 patients, of whom 117 (93·6 per cent) attended 1-year follow-up. At 1 year, the treated part of the GSV was fully occluded in all patients in the EVLA and RFA groups, and in 45 of 55 in the MOCA group (occlusion rates 100, 100 and 82 per cent respectively; P = 0·002). The preoperative GSV diameter was associated with the recanalization rate of the proximal GSV in the MOCA group. At 1 year after treatment, disease-specific life quality was similar in the three groups. CONCLUSION: The GSV occlusion rate 1 year after treatment was significantly higher after EVLA and RFA than after MOCA. Quality of life was similar between interventions.

AIMS: To estimate the incidence of Type 2 diabetes in children aged <17 years, compare this with similar data 10 years ago, and characterize clinical features at diagnosis in the UK and Republic of Ireland. METHODS: Using the British Paediatric Surveillance Unit reporting framework, cases of Type 2 diabetes diagnosed in children aged <17 years between 1 April 2015 and 30 April 2016 were reported each month. RESULTS: A total of 106 cases were reported, giving a UK incidence of 0.72/100 000 (95% CI 0.58-0.88). Children from ethnic minorities had significantly higher incidence compared with white children (0.44/100 000) with rates of 2.92/100 000 and 1.67/100 000, in Asian and BACBB (black/African/Caribbean/black British) children respectively. Sixty-seven percent were girls and 81% had a family history of Type 2 diabetes. The mean BMI sd score at diagnosis was 2.89 (2.88, girls; 2.92, boys); 81% were obese. Children of Asian ethnicity had a significantly lower BMI sd score compared with white children (P<0.001). There was a trend in increased incidence from 2005 to 2015, with a rate ratio of 1.35 (95% CI 0.99-1.84), although this was not statistically significant (P=0.062). There was statistical evidence of increased incidence among girls (P=0.03) and children of South-Asian ethnicity (P=0.01) when comparing the 2005 and 2015 surveys. CONCLUSIONS: Type 2 diabetes remains far less common than Type 1 diabetes in childhood in the UK, but the number of cases continues to rise, with significantly increased incidence among girls and South-Asian children over a decade. Female gender, family history, non-white ethnicity and obesity were found to be strongly associated with the condition.

AIM: To assess cholesterol screening of children with Type 1 diabetes by diabetes professionals using a survey of current practice, given that National Institute of Health and Care Excellence guidelines on childhood Type 1 diabetes do not recommend cholesterol screening, yet the National Paediatric Diabetes Audit has an annual cholesterol measure (> 12 years) as a key outcome indicator. METHODS: An online survey was sent to 280 members of the Association of Children's Diabetes Clinicians to assess cholesterol screening practice in children. RESULTS: A total of 87 diabetes professionals (31%) responded. The results showed that 94% of respondents measured cholesterol, 33% did this annually on all children, and 7% measured fasting cholesterol. A total of 63% used no guidelines to decide treatment or further investigation. The definition of 'high' cholesterol varied from > 4.5 to > 8 mmol/l, with 40% giving no response or specific level. Only 14% of clinicians had started statin therapy in their diabetes clinic in the previous 5 years. CONCLUSION: Whilst the majority of diabetes professionals measured cholesterol in children with Type 1 diabetes, there was marked variability in sampling, in children screened and in action taken if levels were considered abnormal. It is debatable whether cholesterol measures should be undertaken, certainly more than once, and whether cholesterol level should feature as a key outcome in the national audit in future.

OBJECTIVES: The purpose of this prospective study was to evaluate the occlusion rate, clinical severity, disease specific health related quality of life (HRQoL), and safety in patients with great saphenous vein (GSV) reflux 3 years after a single treatment session of catheter directed foam sclerotherapy (CDFS) combined with peri-saphenous infiltration of tumescent local anaesthesia (TLA). METHODS: A total of 249 patients with symptomatic unilateral GSV incompetence underwent CDFS combined with TLA and were followed up for 3 years. The primary outcome was complete obliteration of the treated segment of the GSV. Secondary outcomes were changes in Venous Clinical Severity Score (VCSS) and Chronic Venous Insufficiency Quality of Life Questionnaire (CIVIQ) score, absence of above knee GSV reflux, and safety of treatment. RESULTS: Three years after CDFS, the estimated cumulative proportion of persistently obliterated above knee GSV was 81.5%. Freedom from above knee GSV reflux was demonstrated in 89.6% of patients. Both the VCSS and CIVIQ score improved significantly (p < .0001 and <.0001, respectively). No major adverse events were encountered. Thrombophlebitis, skin pigmentation/matting, and transient scotomata were reported in 2%, 7.8%, and 0.8% of cases, respectively. CONCLUSION: CDFS combined with TLA for treatment of GSV incompetence yields good mid-term results in terms of occlusion rate, clinical severity, patients' QoL, and safety.

OBJECTIVES: To explore centre-level variation in fluoride treatment and oral health outcomes and to examine the association of individual- and area-level risk factors with dental decay in Cleft Care UK (CCUK). SETTING: Two hundred and sixty-eight 5-year-old British children with non-syndromic unilateral cleft lip and palate (UCLP). MATERIALS AND METHODS: Data on caries and developmental defects of enamel (DDE) were collected. The child's history of fluoride ingestion and postcode was used to assess exposure to fluoridated water. Centre-level variation in fluoride exposure and caries was examined using hierarchical regression. Poisson regression was used to estimate the association between individual- and area-level fluoride exposures and outcome. RESULTS: Children had high levels of caries, rampant caries and DDE. There was no evidence of variation between centres in the number of children with caries or rampant decay. There was evidence of variation in prescription of fluoride tablets and varnish and the type of toothpaste used. Area level of deprivation was associated with a higher risk of dental caries-risk ratio (RR) in the lowest quartile versus the rest was 1.43 (95% CI 1.13 to 1.81). Use of fluoride tablets and varnish was associated with higher risk of caries-RR 1.73 (95% CI 1.29 to 2.32) and RR 1.33 (95% CI 1.04 to 1.70), respectively, adjusted for age, sex and deprivation. CONCLUSION: The association with use of fluoride tablets and varnish probably reflects reverse causality but indicates the need for early preventative interventions in children with UCLP.

OBJECTIVES: To explore centre-level variation in otitis media with effusion (OME), hearing loss and treatments in children in Cleft Care UK (CCUK) and to examine the association between OME, hearing loss and developmental outcomes at 5 and 7 years. SETTING AND SAMPLE POPULATION: Two hundred and sixty-eight 5-year-old British children with non-syndromic unilateral cleft lip and palate (UCLP) recruited to CCUK. MATERIALS AND METHODS: Children had air and bone conduction audiometry at age 5. Information on grommet and hearing aid treatment was obtained from parental questionnaire and medical notes. Hearing loss at age 5 was defined as >20 dB in the better ear and history of OME and hearing loss was determined from past treatment. Children with sensorineural hearing loss were excluded. Associations were examined with speech, behaviour and self-confidence at age 5 and educational attainment at age 7. Centre variation was examined using hierarchical models and associations between hearing variables and developmental outcomes were examined using logistic regression. RESULTS: There was centre-level variation in early grommet placement (variance partition coefficient (VPC) 18%, P=.001) and fitting of hearing aids (VPC 8%, P=.03). A history of OME and hearing loss was associated with poor intelligibility of speech (adjusted odds ratio=2.87, 95% CI 1.42-5.77) and aspects of educational attainment. CONCLUSIONS: Hearing loss is an important determinant of poor speech and treatment variation across centres suggest management of OME and hearing loss could be improved.

OBJECTIVES: The aims of this study were to describe child behavioural and psychosocial outcomes associated with appearance and speech in the Cleft Care UK (CCUK) study. We also wanted to explore centre-level variation in child outcomes and investigate individual predictors of such outcomes. SETTING AND SAMPLE POPULATION: Two hundred and sixty-eight five-year-old children with non-syndromic unilateral cleft lip and palate (UCLP) recruited to CCUK. MATERIALS AND METHODS: Parents completed the Strengths and Difficulties questionnaire (SDQ) and reported their own perceptions of the child's self-confidence. Child facial appearance and symmetry were assessed using photographs, and intelligibility of speech was derived from audio-visual speech recordings. Centre-level variation in behavioural and psychosocial outcomes was examined using hierarchical models, and associations with clinical outcomes were examined using logit regression models. RESULTS: Children with UCLP had a higher hyperactive difficulty score than the general population. For boys, the average score was 4.5 vs 4.1 (P=.03), and for girls, the average score was 3.8 vs 3.1 (P=.008). There was no evidence of centre-level variation for behaviour or parental perceptions of the child's self-confidence. There is no evidence of associations between self-confidence and SDQ scores and either facial appearance or behaviour. CONCLUSIONS: Children born with UCLP have higher levels of behaviour problems than the general population.

OBJECTIVES: To investigate centre-level variation in speech intervention and outcome and factors associated with a speech disorder in children in Cleft Care UK (CCUK). SETTING AND SAMPLE POPULATION: Two hundred and sixty-eight 5-year-old British children with non-syndromic unilateral cleft lip and palate recruited to CCUK. MATERIALS AND METHODS: Centre-based therapists undertook audio-video recordings. Perceptual analysis was undertaken using the CAPS-A tool. Speech outcomes were based on structural and articulation scores, and intelligibility/distinctiveness. Between-centre variation in treatment and outcomes were examined using multilevel models. These models were extended to estimate the association between a range of factors (hearing loss, speech intervention, fistula, secondary speech surgery for velopharyngeal insufficiency, socio-economic status, gender, and parental happiness with speech) and speech outcomes. RESULTS: There was centre-level variation in secondary speech surgery, speech intervention, structure and intelligibility outcomes. Children with a history of speech intervention had a lower odds of poor intelligibility/distinctiveness, 0.1 (95% CI: 0.0-0.4). Parental concern was associated with a higher odds of poor intelligibility/distinctiveness, 13.2 (95% CI: 4.9-35.1). Poor speech outcomes were associated with a fistula, secondary speech surgery and history of hearing loss. CONCLUSIONS: Within the centralized service there is centre-level variation in secondary speech surgery, intervention and speech outcomes. These findings support the importance of early management of fistulae, effective management of velopharyngeal insufficiency and hearing impairment, and most importantly speech intervention in the preschool years. Parental concern about speech is a good indicator of speech status.

OBJECTIVES: To summarize and discuss centre-level variation across a range of treatment and outcome measures and examine individual and ecological determinants of outcome in children in Cleft Care UK (CCUK). SETTING AND SAMPLE POPULATION: Two hundred and sixty-eight 5-year-old British children with non-syndromic unilateral cleft lip and palate (UCLP) recruited to CCUK and treated within a centralized service. MATERIALS AND METHODS: Children had a range of treatment and outcome measures collected at a 5-year audit clinic. These outcomes included dento-alveolar arch relationships from study models, measures of facial appearance from cropped photographs, hearing loss from audiological assessment, speech from speech recordings, self-confidence and strengths and difficulties from parental self-report. Data were collected on educational attainment at age 7 using record linkage. Centre variation was examined using hierarchical regression and associations between variables were examined using logistic or poisson regression. RESULTS: There was centre-level variation for some treatments (early grommet placement, fitting of hearing aids, fluoride treatment, secondary speech surgery and treatment for cleft speech characteristics) and for some outcomes (intelligibility of speech). Hearing loss was associated with a higher risk of poor speech while speech therapy was associated with a lower risk of poor speech. Children had high levels of caries but levels of preventative treatment (fluoride varnish and tablets) were low. CONCLUSIONS: Further improvements to and monitoring of the current centralized model of care are required to ensure the best outcomes for all children with cleft lip and palate.

OBJECTIVES: Outline methods used to describe centre-level variation in treatment and outcome in children in the Cleft Care UK (CCUK) study. Report centre-level variation in dento-facial outcomes. SETTING AND SAMPLE POPULATION: Two hundred and sixty-eight five-year-old British children with non-syndromic unilateral cleft lip and palate (UCLP). MATERIALS AND METHODS: Between January 2011 and December 2012, data were collected on a comprehensive range of outcomes. Child facial appearance and symmetry were assessed using photographic pictures. Dental arch relationships were assessed from standardized dental study models. Hierarchical statistical models were used to predict overall means and the variance partition coefficient (VPC)-a measure of amount of variation in treatment or outcome explained by the centre. RESULTS: Data on dento-alveolar arch relationships and facial appearance were available on 197 and 252 children, respectively. The median age of the children was 5.5 years, and 68% were boys. Variation was described across 13 centres. There was no evidence of centre-level variation in good or poor dento-alveolar arch relationships with a VPC of 4% and 3%, respectively. Similarly, there was no evidence of centre-level variation in good or poor facial appearance with a VPC of 2% and 5%, respectively. CONCLUSIONS: There was no evidence of centre-level variation for dento-facial outcomes although this study only had the power to detect large variation between sites.

Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable.

Formaldehyde is frequently used in occupational environments, its toxicity concerns to all who work closely with it such as anatomists. Nigella sativa is an amazing herb with a rich historical and religious background; its seeds are the source of its active ingredients. The purpose of the present study was to evaluate the role of Nigella sativa oil on corneal injury induced by formaldehyde in adult male albino rats. Forty adult male albino rats were divided randomly to four groups 10 rats each: I - Control group, II - Formaldehyde exposed group, III - Nigella sativa oil group (40 mg/kg/day) via intragastric tube daily for 2 weeks and IV - Formaldehyde and Nigella sativa group. Rats were sacrificed with ether, the corneas were extracted, one processed for haematoxylin and eosin stain and the other was used for transmission electron microscopic examination. Our results in group II revealed marked disorganisation, erosion, vacuolation and necrosis of epithelial cells with loss of parts of epithelial layer. Large congested invasion of blood vessels with separation and disorganisation of stromal fibrils. The corneas of group IV showed intact layers of epithelial cells with appearance close to control group. Star shaped cells (limbal stem cells) were obviously noticed in basal and intermediate layer with intact Bowman's membrane. Stroma showed regular parallel collagen, limbal stem cells were also noticed in group III. We concluded that Nigella sativa oil can ameliorate the toxic changes of formaldehyde on rat corneas. (.

Poor nutrition of women during pregnancy causes reduction in foetal growth and can adversely affect the development of the foetal lungs. The purpose of the present study was to assess the effects of maternal protein restriction on the postnatal lung development in neonatal period, and on lung structure in adult rat offspring. Female virgin Sprague-Dawley albino rats (more than 200 g) were used. One male rat was introduced into a cage with one female for matting. Once the pregnancy was confirmed, pregnant rats were divided into two main groups; each consists of 6 female as follow: 1 - normally nourished group; 2 - protein deficient group. After delivery, offspring were subdivided into three groups: 1 day after delivery, 2 weeks and 2 months postnatal. Rat body and lung weight were recorded and ratio of lung weight to body weight was assessed. Total plasma protein and serum albumin were assessed for all groups. Lung tissue stained with H&E for histological and morphometric analysis. Immunohistochemistry was performed to evaluate the number of cells positive for pulmonary surfactant protein A. Our results showed that protein restriction interfere with neonatal and postnatal lung development resulting in morphological and morphometric changes of normal lung development. We concluded that protein deficiency lead to developmental retardation of lung.
RESUMEN
OBJECTIVE: Superficial venous reflux and varicose veins are common. The aim of this randomized controlled trial was to assess effectiveness of compression therapy compared with surgery for superficial venous reflux. METHODS: 153 patients with CEAP class C2-C3 and superficial venous reflux were randomized to receive either conservative treatment (compression stockings) (n = 77) or surgery (n = 76). Clinical examination including duplex ultrasound (DUS) was performed at entry and 1 and 2 years after randomization (compression group) or surgery (surgery group). Venous Clinical Severity Score without compression stockings (VCSS-S), Venous Segmental Disease Score (VSDS), Venous Disability Score (VDS), and health-related quality of life (HRQoL) were assessed at entry and at the follow-ups. Data were analysed on an intention-to-treat basis and according to the actual treatment performed. RESULTS: At 2 years, 70/76 patients in the surgery group and 11/77 patients in the compression group had been operated on. VCSS-S decreased from 4.6 to 3.5 in the compression group (p < .01) and from 4.8 to 0.6 in the surgery group (p < .001). VSDS decreased from 7.7 to 7.0 in the compression group and from 8.2 to 0.9 in the surgery group (p < .0001). HRQoL did not change in the compression group, but improved significantly in the surgery group. CONCLUSION: The surgical elimination of non-complicated superficial venous reflux is an effective treatment when compared with providing compression stockings only.

Cataracts, known for lens clouding and being a common cause of visual impairment, persist as a primary contributor to vision loss and blindness, presenting notable diagnostic and prognostic challenges. This work presents a novel framework called the Cataract States Detection Network (CSDNet), which utilizes deep learning methods to improve the detection of cataract states. The aim is to create a framework that is more lightweight and adaptable for use in environments or devices with limited memory or storage capacity. This involves reducing the number of trainable parameters while still allowing for effective learning of representations from data. Additionally, the framework is designed to be suitable for real-time or near-real-time applications where rapid inference is essential. This study utilizes cataract and normal images from the Ocular Disease Intelligent Recognition (ODIR) database. The suggested model employs smaller kernels, fewer training parameters, and layers to efficiently decrease the number of trainable parameters, thereby lowering computational costs and average running time compared to other pre-trained models such as VGG19, ResNet50, DenseNet201, MIRNet, Inception V3, Xception, and Efficient net B0. The experimental results illustrate that the proposed approach achieves a binary classification accuracy of 97.24% (normal or cataract) and an average cataract state detection accuracy of 98.17% (normal, grade 1-minimal cloudiness, grade 2-immature cataract, grade 3-mature cataract, and grade 4-hyper mature cataract), competing with state-of-the-art cataract detection methods. The resulting model is lightweight at 17 MB and has fewer trainable parameters (175, 617), making it suitable for deployment in environments or devices with constrained memory or storage capacity. With a runtime of 212 ms, it is well-suited for real-time or near-real-time applications requiring rapid inference.
