To compare the long-term outcomes of monovision surgery using implantable collamer lens (ICL) V4c and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) in myopic patients with early presbyopia. This case series study included 48 eyes of 24 patients (male/female: 10/14, mean age 45.50 ± 3.82 years) and followed-up for 4.5 years (54.00 ± 9.77 months). Patients were examined for spherical equivalent, uncorrected distance visual acuity, corrected distance visual acuity, intraocular pressure, presbyopic add power, visual acuity (VA) (logMAR) of dominant eyes (D-eye), non-dominant eyes (nD-eye), and both eyes (Bi) at 0.4 m, 0.8 m, and 5 m, corneal wavefront aberration, and contrast sensitivity (CS). All surgeries were uneventful. The safety indices of ICL V4c group and FS-LASIK group were 1.17 ± 0.30 and 0.98 ± 0.20 (p < 0.05), and the efficacy indices were 0.79 ± 0.07 and 0.52 ± 0.07 (p < 0.05) respectively. The binocular VA (logMAR) of ICL V4c group and FS-LASIK group at 5.0 m were: 0.02 ± 0.11, 0.18 ± 0.30; 0.8 m: 0.09 ± 0.12, − 0.01 ± 0.11; 0.4 m: − 0.02 ± 0.06, − 0.03 ± 0.08, (p > 0.05 at three distances). Compared with ICL V4c group, lower CS was observed at 1.0 cpd in the FS-LASIK group (1.07 ± 0.31 vs. 0.80 ± 0.51, p = 0.043). Monovision surgery using ICL V4c and FS-LASIK provides good binocular visual acuity at near-to-far distances in myopia patients in the presbyopia age group.

Global hunger has increased recently, returning to levels observed a decade ago. Climate change is identified as a key factor contributing to these increases and is a significant cause of severe food crises. When combined with population growth and globalization, future climate variability is expected to significantly affect global food security. This study examined the influence of climate variability, globalization, and population growth on food security (FS) in Pakistan from 1995 to 2023. Food security data was sourced from the Food and Agricultural Organization, and globalization data was obtained from the KOF Globalization Index. Datasets on climate variability, population growth, unemployment, and inflation were collected from the World Development Indicators. A two-layer principal component analysis was utilized to develop the food security index. Multivariate Generalized Auto-Regressive Conditional Heteroscedasticity was used to assess the impact of globalization, population growth, and climate variability on food security. All indexed components explained more than 50% of the variance, resulting in a food security eigenvalue of 3.603 with a 0.901 proportion. The findings indicated that population growth and climate variability significantly negatively affect Pakistan’s food security. Furthermore, the study found that globalization notably mitigates the adverse effects of climate variability and population growth on food security. This research may help alleviate the risk of future undernourishment, reverse current trends of escalating food insecurity, and support the sustainable development goal of eliminating global hunger by 2030.

1. IntroductionComplex remote sensing scene interpretation is becoming increasingly important, wherein scene classification is one of the fundamental tasks. This is a technique for constructing the correspondence between image and scene functional areas [1,2] with the objective of categorizing the content of remote sensing scene images into respective semantic clusters.

PatientsThis retrospective study included 389 NPC patients who received NACT between January 2017 and January 2023. The MRI used to construct the predictive models were all obtained prior to the performance of the NACT treatment. The patients were from three institutions: the Affiliated Hospital of Southwest Medical University (n = 311), Qingyang People’s Hospital (n = 36), and Xinzhou People’s Hospital (n = 42).
